What is density?

Density is a physical property of matter that describes how much mass is present in a given volume of a substance. It is defined as the amount of mass per unit volume and is usually expressed in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The formula for density is:

Density = Mass / Volume

First, we need to find the volume of 48.5 kg of gasoline using its density:

Volume = Mass / Density = 48.5 kg / 900 g/L = 0.05389 L

Next, we can find the cost of this volume of gasoline:

Cost = Volume x Price per liter = 0.05389 L x $0.83/L = $0.0448

Rounding this to the nearest cent, we get:

Cost = $0.04

Therefore, the cost of 48.5 kg of gasoline is approximately $0.04.

The correct statement regarding the average rate of change of the functions f(x) and g(x) on the interval [-2,2] is given as follows:

Over the interval [-2,2], the function f is increasing at a faster rate than function g is decreasing.

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.

For the function f(x), the numeric values at x = -2 and x = 2 are given as follows:

Hence the rate is of:

(26 - 14)/(2 - (-2)) = 12/4 = 3. -> positive rate -> increasing.

For function g(x), the rate is given as follows:

The probability against Brian winning a gift card are approximately 3.118 to 1.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event happening is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in various fields, such as statistics, finance, science, engineering, and gaming, to make predictions and decisions based on uncertain events.

In the given question,

The probability of the arrow stopping on a black slice is 3/10. Therefore, the probability of the arrow stopping on a non-black slice is 7/10.

If the arrow stops on the border of two slices, the wheel is spun again, so Brian has another chance to win. The probability of the arrow stopping on a non-black slice is 7/10, so the probability of the arrow stopping on a black slice on the second spin is 3/7.

To find the odds against Brian winning a gift card, we first find the probability of him not winning a gift card on either spin:

P(not winning) = P(non-black on first spin) + P(black on first spin and non-black on second spin)

P(not winning) = (7/10) + (3/10) × (4/7)

P(not winning) = 0.7571

The probability of not winning is 0.7571, so the odds against winning are:

Odds against winning = P(not winning) / P(winning)

Odds against winning = 0.7571 / 0.2429

Odds against winning = 3.118

Therefore, the odds against Brian winning a gift card are approximately 3.118 to 1.

y/8 ≤ 2 is equivalent to y ≤ 16.

Inequality in math is a statement that two expressions or values are not equal. This can be expressed using symbols such as >, <, ≥, or ≤. Inequality problems are used to solve for a variable that is not necessarily equal to a given value. An example of an inequality problem is finding the value of a variable in the equation x > 5. The solution to this problem is all real numbers greater than 5.

This is happening because when we divide both sides of the inequality y/8 by 8, we are essentially dividing both sides of the inequality by the same number. This preserves the order of the numbers and the inequality sign. So, dividing both sides by 8 results in y ≤ 16, which is the same as y/8 ≤ 2.

Answer:

the value of x for which the volume of the box will be as large as possible is approximately 2.67 inches.

Step-by-step explanation:

Let x be the length of the side of the squares that are cut out of the corners of the cardboard. Then the dimensions of the base of the rectangular box will be:

Length = 16 - 2x (since two squares of side x are cut out of each end of the 16-inch length)

Width = 16 - 2x (since two squares of side x are cut out of each end of the 16-inch width)

The height of the box will be x, since that is the height of the squares that were cut out.

The volume of the box can be expressed as:

V = Length × Width × Height

V = (16 - 2x) × (16 - 2x) × x

V = 4x^3 - 64x^2 + 256x

To find the value of x that maximizes the volume of the box, we can take the derivative of V with respect to x and set it equal to zero:

dV/dx = 12x^2 - 128x + 256 = 0

We can solve this quadratic equation for x using the quadratic formula:

x = [128 ± sqrt(128^2 - 4 × 12 × 256)] / (2 × 12)

x = [128 ± sqrt(16384)] / 24

x = [128 ± 128] / 24

x = 10.67 or x = 2.67

Since x represents the length of a side of a square, it must be non-negative. Therefore, the only valid solution is x = 2.67 inches.

So, the value of x for which the volume of the box will be as large as possible is approximately 2.67 inches.

Answer: Let x be the side length of the square corners that are cut out of the cardboard. Then the dimensions of the base of the box (after the corners have been cut out and the flaps folded up) are 16-2x by 16-2x, and the height of the box is x.

The volume V of the box is given by:

V = (16-2x)(16-2x)(x)

Expanding this expression gives:

V = 4x^3 - 64x^2 + 256x

To find the value of x that maximizes V, we can take the derivative of V with respect to x and set it equal to zero:

dV/dx = 12x^2 - 128x + 256 = 0

Dividing both sides by 4 gives:

3x^2 - 32x + 64 = 0

This quadratic equation can be factored as:

(3x - 16)(x - 4) = 0

So the solutions are x = 16/3 and x = 4.

Since x must be less than half of 16 (the side length of the cardboard), we can reject x = 16/3. Therefore, the value of x that maximizes the volume of the box is x = 4 inches.

Considering the definition of perimeter, the length and width of the rectangle is 85 in and 7 in respectively.

The perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.

The perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure.

A rectangle is a geometric figure that has two pairs of sides of equal length. The expression to calculate the perimeter of a rectangle is:

Perimeter= 2× length + 2× width

In this case, you know

Replacing in the definition of the perimeter of the rectangle:

184= 2× (11×width + 8) + 2× width

Solving:

184= 2×11×width + 2×8 + 2× width

184= 22×width + 16 + 2× width

184 - 16= 22×width + 2× width

168= 24×width

168÷ 24= width

7 in= width

So, the length can be calculated as:

lenght= 11×7 in + 8 in

lenght= 85 in

Therefore , the solution of the given problem of triangle comes out to be  BZ = (8/9) * BC = 40/9 as a result.

Due to its two or more extra sections, a trapezoid is a polygon. Its shape is a simple rectangle. Only the three edges A, B, but instead C distinguish a triangle from a regular triangle. Euclidean geometry produces a singular area rather than a cube when the borders are not perfectly collinear. Triangular shapes are defined as having three sides and three angles. Angles are formed by the meeting of a quadrilateral's 3 sides.

Here,

Let D represent the intersection of the angle bisector BY and the side AC, and let E represent the intersection of the angle bisector CZ and the side AB.

=>BC² = AB² + AC² - 2AB * AC * cos(BAC)

However, since BY and CZ are angle bisectors, we can calculate BAC as follows:

=> BC² = 8² + 9² - 2(8)(9)cos[(180° - (ABC + ACB))/2]

If we simplify, we get:

=> BC² = 145 - 144cos[(ABC + ACB)/2]

Using the angle bisector theory once more, we have the following:

=> AD/DC = 8/BC

=> DC = BC(AD/8)

Simplifying and substituting into the Law of Cosines equation yields:

=> BC² = 145 - 144cos[(ABC + ACB)/2]

=>  145 - 144cos[(180° - BAC)/2]

=> 145 - 144cos(B/2)

in which B Equals ABC.

We can now replace the value of BZ that we discovered earlier with:

=> BZ = (8/9) * BC

and solve for BC:

=> BC² = 145 - 144cos(B/2)

=>  (9/8)² * (145 - 144cos(B/2)) + (8/9)² * BZ²

Simplifying and substituting BZ results in:

BC² = 25

Since BC is a length, we obtain: by taking the positive square root.

=> BC = 5

=> BZ = (8/9) * BC = 40/9 as a result.

a) Note that given the above function the height of the Frisbee each second it is in the air are:

b) The frisbee lasts  t [tex]\approx[/tex] 2.6 (s) in the air.

Recall that the function given is -16t² + 40t + 5
t=0; and h = 5

a)
Where t is 1
h = -16t² + 40t + 5

h= -16(1)² + 40(1) + 5

h= -16 + 40 + 5

h= 24 + 5

h= 29, thus, where = 1, h = 29

Using a similar sequence above, where t is
t=2; h = 21 feet; and where

t =3; h = -19

b) in this case, we must set h(t) = 0

⇒ -16t² + 40t + 5 = 0
To solve for t in the equation -16t² + 40t + 5 = 0, we can use the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation.

In this case, a = -16, b = 40, and c = 5, so substituting these values into the quadratic formula, we get:

t = (-40 ± √(40² - 4(-16)(5))) / 2(-16)

Simplifying:

t = (-40 ± √(1600 + 320)) / (-32)

t = (-40 ± √(1920)) / (-32)

t = (-40 ± 8 √(30)) / (-32)

t = (5/4) ± (√(30)/4)

Thus we have:

t = (5/4) + (√(30)/4) or t = (5/4) - (√(30)/4)

t₁ = 1.25 + (5.477225575051661134569697828008/4) or
t₂ = 1.25 - (5.477225575051661134569697828008/4)

t₁ = 1.25 + 1.369306393762915283642424457002

Answer:

the total force on the port hole due to liquid pressure is approximately 7400 pounds.

Step-by-step explanation:

The area of the circle is A = πr^2, where r = d/2 = 1 foot is the radius of the circle. So, the area is A = π(1 ft)^2 = π ft^2.

The port hole is submerged in water, with a height of 6 feet. The pressure of water at a depth of h feet is given by the formula P = ρgh, where ρ = 62.4 lb/ft^3 is the density of water, and g = 32.2 ft/s^2 is the acceleration due to gravity.

The total force on the port hole due to liquid pressure is the product of the pressure and the area of the circle, so we have:

F = P × A = ρgh × A = 62.4 lb/ft^3 × 32.2 ft/s^2 × 6 ft × π ft^2 ≈ 7400 lb

Therefore, the total force on the port hole due to liquid pressure is approximately 7400 pounds.

The employee must sell $32,000 worth of merchandise in the month to make a total of $4,000.

Let's first find out how much commission an employee would earn if they sold $x in a month,

where x is the amount of sales over $7,000.

The commission earned would be 8% of x, or 0.08x.

To earn a total of $4,000 for the month, the employee would need to earn a base salary of $2,000 plus an additional $2,000 in commission.

So we can set up the following equation:

0.08x + 2000 = 4000

Subtracting 2000 from both sides, we get:

0.08x = 2000

Dividing both sides by 0.08, we get:

x = 25000

Therefore, the employee must sell $25,000 in a month to make a total of $4,000 for the month. Note that this is the amount of sales over $7,000, so the total sales for the month would be $25,000 + $7,000 = $32,000.
