35 POINTS ANSWER FOR BRAINLIST
Colbie solved the equation below by completing the square. Did she complete the square correctly? Explain why or why not? Correct the mistake(s) – if there are any.
Answers
Answer:
Colbie did not complete the square correctly.
Colbie failed to add the square of half the coefficient of the term in x to both sides of the equation. She only added 25 to the left side of the equation. She also factored x² + 10x + 25 incorrectly by using a subtraction sign in the binomial rather than an addition sign.
Step-by-step explanation:
Given quadratic equation:
[tex]2x^2+20x-48=0[/tex]
As the leading coefficient is not one, to complete the square we must first divide both sides of the equation by the leading coefficient, 2:
[tex]\dfrac{2x^2+20x-48}{2}=\dfrac{0}{2}[/tex]
[tex]x^2+10x-24=0[/tex]
Now move the constant to the right side of the equation by adding 24 to both sides of the equation:
[tex]\begin{array}{rcr}x^2+10x-24&=&0\\\vphantom{\dfrac12}+24 & &+24\\\cline{1-3}\vphantom{\dfrac12}x^2+10x\phantom{-24.}&=&24\end{array}[/tex]
We need to make the left side of the equation a perfect square trinomial. To do this, add the square of half the coefficient of the term in x to both sides of the equation.
The coefficient of the term in x is 10. Therefore, the square of half of this is 25:
[tex]\left(\dfrac{10}{2}\right)^2=5^2=25[/tex]
This is the point at which Colbie made her first mistake. She didn't add the square of half the coefficient of the term in x to both sides of the equation - she only added it to the left side.
Add 25 to both sides of the equation:
[tex]x^2+10x+25=24+25[/tex]
[tex]x^2+10x+25=49[/tex]
To continue to solve the equation, factor the perfect square trinomial on the left side of the equation:
[tex](x+5)^2=49[/tex]
↑ Colbie made her second mistake here. She factored x² + 10x + 25 incorrectly by using a subtraction sign in the binomial rather than an addition sign.
Square root both sides:
[tex]\sqrt{(x+5)^2}=\sqrt{49}[/tex]
[tex]x+5=\pm7[/tex]
Subtract 5 from both sides:
[tex]x+5-5=-5\pm7[/tex]
[tex]x=-5\pm7[/tex]
Therefore, the solutions are:
[tex]x=-5+7=2[/tex]
[tex]x=-5-7=-12[/tex]

If sin 0 = 3/4 and angle 0 is in quadrant I, what is the exact value of tan20 in simplest radical form?
Answers
The exact value of tan2θ in simplest radical form is -21/√7.
What is the value of tan2θ?The value of tan2θ is calculated as follows;
From Pythagorean identity, we know that;
sin² θ + cos² θ = 1
cos² θ is calculated as follows;
(3/4)² + cos² θ = 1
9/16 + cos² θ = 1
cos² θ = 1 - 9/16
cos² θ = 7/16
cos θ = √(7/16)
tan θ = sin θ / cos θ = 3/4 x 4/√7 = 3/√7
Now, we will find tan 2θ;
tan 2θ = 2tan θ / (1 - tan² θ)
tan 2θ = 2(3/√7) / (1 - (3/√7)²)
tan 2θ = (6/√7) / (-2/7)

Analyze a CSR capital investment proposal for Ganon Inc.
Ganon Inc. is evaluating a proposal to replace its HID (high intensity discharge) lighting with LED (light emitting diode) lighting throughout its warehouse. LED lighting consumes less power and lasts longer than HID lighting for similar performance. The following information was developed:
Line Item Description Value
HID watt hour consumption per fixture 500 watts per hr.
LED watt hour consumption per fixture 300 watts per hr.
Number of fixtures 800
Lifetime investment cost (in present value terms)
to replace each HID fixture with LED $300
Operating hours per day 10
Operating days per year 300
Metered utility rate per kilowatt-hour (kwh)* $0.12
*Note: A kilowatt-hour is equal to 1,000 watts per hour.
a. Determine the investment cost for replacing the 800 fixtures.
$240,000
b. Determine the annual utility cost savings from employing the new energy solution.
c. Should the proposal be accepted?
Yes
Evaluate the proposal using net present value, assuming a 15-year life and 8% minimum rate of return. (Click here to view Present Value of Ordinary Annuity.)
Answers
a)
The investment cost for replacing the 800 fixtures is $240,000.
b)
Annual utility cost savings is $57,600/year.
c)
Since the NPV is positive, the proposal should be accepted as it generates a positive return and is expected to be profitable.
We have,
a.
The investment cost for replacing the 800 fixtures is given as $300 per fixture, so the total investment cost would be:
Total Investment Cost = Number of fixtures x Investment cost per fixture
Total Investment Cost = 800 x $300
Total Investment Cost = $240,000
b.
To calculate the annual utility cost savings, we need to find the difference in the watt-hour consumption per fixture between HID and LED lighting, and multiply it by the number of fixtures, operating hours per day, operating days per year, and the metered utility rate per kilowatt-hour:
Energy consumption savings per fixture per hour = HID watt hour consumption - LED watt hour consumption
Energy consumption savings per fixture per hour = 500 watts/hr - 300 watts/hr
Energy consumption savings per fixture per hour = 200 watts/hr
Total energy consumption savings per hour for 800 fixtures:
= Energy consumption savings per fixture per hour x Number of fixtures
Total energy consumption savings per hour for 800 fixtures.
= 200 watts/hr x 800
Total energy consumption savings per hour for 800 fixtures.
= 160,000 watts/hr
Total energy consumption savings per year = Total energy consumption savings per hour x Operating hours per day x Operating days per year
Total energy consumption savings per year = 160,000 watts/hr x 10 hrs/day x 300 days/year
Total energy consumption savings per year = 480,000,000 watt-hours/year
Total energy consumption savings per year in kilowatt-hours (kWh):
= Total energy consumption savings per year / 1,000
Total energy consumption savings per year in kWh = 480,000,000 / 1,000
Total energy consumption savings per year in kWh = 480,000 kWh/year
Annual utility cost savings:
= Total energy consumption savings per year in kWh x Metered utility rate per kWh
Annual utility cost savings = 480,000 kWh/year x $0.12/kWh
Annual utility cost savings = $57,600/year
c.
To evaluate the proposal using net present value (NPV), we need to calculate the present value of the investment cost and the present value of the annual utility cost savings over a 15-year period.
Using the Present Value of the Ordinary Annuity formula with a 15-year life and 8% minimum rate of return, we get:
PV of Investment Cost = -$240,000 (negative because it's a cash outflow)
PV of Annual Utility Cost Savings = $514,883.81
NPV = PV of Annual Utility Cost Savings - PV of Investment Cost
NPV = $514,883.81 - (-$240,000)
NPV = $754,883.81
Therefore,
The investment cost for replacing the 800 fixtures is $240,000.
Annual utility cost savings is $57,600/year.
Since the NPV is positive, the proposal should be accepted as it generates a positive return and is expected to be profitable.

the sum of three numbers is 56. the difference of the larges and smallest is 44 and the sum of the two smaller numbers is 16. what are the numbers?
Answers
The three numbers are -2, 42 and 16 these we obtained by solving the equations
Let the three numbers x, y, and z. We know that:
x + y + z = 56 (Equation 1)
z - x = 44 (Equation 2)
x + y = 16 (Equation 3)
From Equation 3, we can solve for one of the variables in terms of the other:
y = 16 - x
Substituting this into Equation 1, we get:
x + (16 - x) + z = 56
Simplifying this equation, we get:
z = 40 - x (Equation 4)
Substituting Equation 4 into Equation 2, we get:
(40 - x) - x = 44
Simplifying this equation, we get:
40 - 2x = 44
Subtracting 40 from both sides, we get:
-2x = 4
Dividing both sides by -2, we get:
x = -2
z = 40 - (-2) = 42
Finally, using Equation 1, we can solve for y:
-2 + y + 42 = 56
y=16
Hence, the three numbers are -2, 42 and 16

The area of a square table top can be represented by (9x^2-30x+25) square feet. The perimeter of the table top is 34 feet. What is the value of x? Explain ow you solved this problem.
Answers
The requried value of x that satisfies the problem is 4.5,
Let's start by finding the side length of the square tabletop, which is equal to the square root of its area. We have:
Area = 9x² - 30x + 25
Side length = √(Area) = √(9x² - 30x + 25)
To find x, we need to use the fact that the perimeter of the table top is 34 feet. The perimeter of a square is given by 4 times the length of one of its sides, so we can write:
Perimeter = 4 * Side length
34 = 4 * √(9x² - 30x + 25)
8.5 = √(9x² - 30x + 25)
9x² - 30x - 47.25 = 0
We can solve this quadratic equation by using the quadratic formula gives,
x = 4.5 and -1.16
Therefore, the value of x that satisfies the problem is approximately 4.5, since the other solution is negative and not meaningful in this context.

(a + 2)/(1 + a + a ^ 2) - (a - 2)/(1 - a + a ^ 2) - (2a ^ 2)/(1 + a ^ 2 + a ^ 4)
Answers
The first term has a denominator of 1 + a + a^2, the second term has a denominator of 1 - a + a^2, and the third term has a denominator of 1 + a^2 + a^4.
To find a common denominator, we need to factor each of the three denominators.
The first denominator can be factored as (a + 1/2)^2 + 3/4.
The second denominator can be factored as (a - 1/2)^2 + 3/4.
The third denominator can be factored as (a^2 - a√2 + 1)(a^2 + a√2 + 1).
Now we can rewrite the expression with a common denominator:
[(a + 2)((a - 1/2)^2 + 3/4) - (a - 2)((a + 1/2)^2 + 3/4) - 2a^2(a^2 - a√2 + 1)(a^2 + a√2 + 1)] / [(a + 1/2)^2 + 3/4][(a - 1/2)^2 + 3/4](a^2 - a√2 + 1)(a^2 + a√2 + 1)]
We can simplify this expression by multiplying out the terms in the numerator and combining like terms. After doing so, we get:
[-4a^4 + 8a^3 - 4a^2 - 4a√2 + 12a - 4√2] / [(a + 1/2)^2 + 3/4][(a - 1/2)^2 + 3/4](a^2 - a√2 + 1)(a^2 + a√2 + 1)]
So the simplified expression is:
(-4a^4 + 8a^3 - 4a^2 - 4a√2 + 12a - 4√2) / [(a + 1/2)^2 + 3/4][(a - 1/2)^2 + 3/4](a^2 - a√2 + 1)(a^2 + a√2 + 1

The distance between (2,2) and (8,2) is 6 units on a coordinate plane. Select all of the pairs of points that are 6 units apart.
Answers
The points are not at a distance of 6 units from each other.
Given that the distance between point (2, 2) and point (8, 2) is 6 units a coordinate plane.
We need to find which other pairs of points are also 6 units apart.
The distance between two points (x₁, y₁), (x₂, y₂) are 6 if and only if either
( x₂ - x₁ = 6 and y₂ = y₁ )or ( x₂ = x₁ and y₂ - y₁ = 6 ).
If either of the conditions is satisfied, then only we can say that the two points has distance of 6 units between them.
Now, As given
Let (x₁, y₁) = ( 2, 2) , (x₂, y₂) = (8, 2)
Check whether the conditions are satisfied or not .
Here x₁ = 2 , x₂ = 8, y₁ = 2, y₂ = 2
Now,
x₂ - x₁ = 8 - 2 = 6 , y₂ - y₁ = 2 - 2 = 0
∴ we get
1st condition is satisfied, So the points have a distance of 6 units between them.
Now,
Let us suppose another point (x₁, y₁) = ( 4, 3) , (x₂, y₂) = (3, 3)
Here x₁ = 4 , x₂ = 3, y₁ = 3, y₂ = 3
Now,
x₂ - x₁ = 4 - 3 = 1 , y₂ - y₁ = 3 - 3 = 0
Here neither of the conditions are satisfied.
So, the points are not at a distance of 6 units from each other.

Answers
Answer: the answer is A=33∘, B=107.5∘, and C=39.5∘ is correct or c
Step-by-step explanation:
To find the angles of triangle ABC with side lengths a=12, b=21, and c=14, we can use the Law of Cosines and then apply the Law of Sines to find the remaining angles. Let's denote the angles as A, B, and C respectively.
According to the Law of Cosines:
c^2 = a^2 + b^2 - 2ab * cos(C)
Plugging in the given side lengths:
14^2 = 12^2 + 21^2 - 2 * 12 * 21 * cos(C)
196 = 144 + 441 - 504 * cos(C)
504 * cos(C) = 389
cos(C) = 389 / 504
C = arccos(389 / 504)

a = [tex]\sqrt{144}[/tex] = 12
then
perimeter = 35 + 37 + 12 = 84 feet

I am confused on this question. "George is building flower boxes to sell as gifts. Draw and label a net to represent a flower box. Then find the amount of material George needs for each box. Explain why you drew the net the way you did." There is also a picture that goes with it down below.
Answers
Answer:
To answer the question, you first need to understand what a net is. A net is a two-dimensional diagram that can be folded to form a three-dimensional object. In the context of this question, a net represents the unfolded and flattened-out shape of a flower box before it is assembled.
To draw a net that represents a flower box, you need to imagine what the box would look like if it were flattened out and unfolded. You can start by drawing a rectangle for the bottom of the box. Then draw four rectangles that represent the sides of the box. Each of the side rectangles should be the same length as the length of the bottom rectangle, and the width of each side rectangle should be the same as the height of the box.
Next, you need to label the net to indicate which sides will be connected to form the box. Label the edges of the rectangles with the corresponding letter to show how the box will be assembled. For example, label the top edge of the bottom rectangle as "A" and the bottom edge of one of the side rectangles as "B". Then, label the side edges of the side rectangle as "C" and "D".
To find the amount of material George needs for each box, you need to calculate the total surface area of the net. The surface area represents the amount of material needed to cover the entire box. You can find the surface area by calculating the area of each rectangle and adding them together.
In this case, the bottom rectangle has an area of 16 square inches, and each of the four side rectangles has an area of 8 square inches. Therefore, the total surface area of the net is:
16 + 4(8) = 48 square inches
This means that George needs 48 square inches of material to make one flower box.
You drew the net the way you did because it represents the flattened-out and unfolded shape of the flower box before it is assembled. Labeling the edges and rectangles helps to visualize how the box will be assembled and allows you to calculate the surface area needed to cover the entire box.

Answer:5.08
4.34 are correct
Step-by-step explanation:We can solve this quadratic equation in sin(θ) by using the substitution u = sin(θ):
6u^2 - 3u - 8 = 0
We can use the quadratic formula to solve for u:
u = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 6, b = -3, and c = -8. Substituting these values, we get:
u = (3 ± sqrt(9 + 192)) / 12
u = (3 ± sqrt(201)) / 12

clara is running a bakery she has made a street sign to direct people to her bakery . She painted one of the post and sign. What is the painted area?8in,8in,5in, 60in, 4in
Answers
The painted area of the sign is approximately 324 square inches. This was calculated by finding the area of the pole, square signboard, and triangle portion of the signboard and adding them together.
To find the painted area, we need to find the area of the pole, the area of the square signboard, and the area of the triangular portion of the signboard.
Area of pole
The pole is a rectangular prism with height 60in and width 4in. Therefore, the area of the pole is:
60in x 4in = 240 sq. in.
Area of square signboard
The square signboard has a side length of 8in. Therefore, the area of the square signboard is:
8in x 8in = 64 sq. in.
Area of triangular portion of the signboard
The triangular portion of the signboard has a base of 8in and a height of 5in. Therefore, the area of the triangular portion of the signboard is:
(1/2) x 8in x 5in = 20 sq. in.
Total painted area
The total painted area is the sum of the area of the pole, the area of the square signboard, and the area of the triangular portion of the signboard. Therefore, the painted area is:
240 sq. in. + 64 sq. in. + 20 sq. in. = 324 sq. in.

To check if a solution is correct for a system of equations, we substitute the values of the solution into both equations and see if they are true.
Let's assume that the solution for the system of equations is (x,y) = (1,-1).
To check if this solution is correct for the first equation y = 2x - 3, we substitute x = 1 and y = -1:
-1 = 2(1) - 3
-1 = -1
Since -1 = -1, the solution (1,-1) satisfies the first equation.
To check if this solution is correct for the second equation y = -1/2x + 2, we substitute x = 1 and y = -1:
-1 = -1/2(1) + 2
-1 = 1
Since -1 is not equal to 1, the solution (1,-1) does not satisfy the second equation.
Therefore, the solution (1,-1) is not a solution for the system of equations y = 2x - 3 and y = -1/2x + 2.
