Answer:

y = 5x - 21

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, 4 ) and (x₂, y₂ ) = (8, 19 )

m = [tex]\frac{19-4}{8-5}[/tex] = [tex]\frac{15}{3}[/tex] = 5 , then

y = 5x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (5, 4 ) , then

4 = 5(5) + c = 25 + c ( subtract 25 from both sides )

- 21 = c

y = 5x - 21 ← equation of line

a. The triangle can be sketched as shown in the attached image.

b.  The side length OE is 4√11 inches

c. The measure of ∠G is 27.82°

a. The triangle can be sketched as shown in the attached image.

b. We can use Pythagoras theorem  to calculate the side length OE. That is:

OE = √(15² - 7²)

OE = 4√11 inches

c. Using trig. ratio:

sin G = (4√11)/15    (opposite/hypotenuse)

sin G = 0.8844

G =  sin⁻¹ (0.8844)

G = 27.82°

Thus, the measure of ∠G is 27.82°

A. Please see attached photo for diagram

B. The length of side OE is 13 inches

C. The measure of  of angle G, ∠G is 62°

We can obtain the the length of OE by using Pythagoras theorem as shown below:

OE² = OG² - GE²

OE² = 15² - 7²

OE² = 225 - 49

OE² = 176

Take the square root of both sides

OE = √176

OE = 13 inches

Thus, the length of OE is 13 inches

The value of angle G, ∠G can be obtained as follow:

Cos G = Adjacent / Hypothenuse

Cos G = 7 / 15

Cos G = 0.4667

Take the inverse of Cos

G = Cos⁻¹ 0.4667

G = 62°

Machines A and B worked for 66 minutes and 6 seconds.

An inequality is a mathematical statement that compares two quantities using one of the inequality symbols: "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).

Inequalities can be solved just like equations, with the goal of finding the set of values that satisfy the inequality.

Here we have

Machine A can pack 8 boxes per​ minute, and Machine B can pack 11 boxes per minute.

Let Machines A and B work for 'x' minutes

Number of boxes packed by Machine A = 8x

Number of boxes packed by Machine B = 11x

The difference between the number of boxes that Machine B has packed and the number of boxes that Machine A has packed is less than 200.

=> | 11x - 8x| < 200

=> 3x < 200

Divide by 3 into both sides

=> 3x/3 < 200/3

=> x < 66.67

=> x < 66.6

The difference is not constant, the sequence is not arithmetic.

An arithmetic sequence is a set of integers where each term is created by multiplying the preceding term by a fixed constant value (known as the common difference). A constant rate of change is modelled by arithmetic sequences in fields like engineering, physics, and financial computations.

For the given series we need to determine if the sequence is arithmetic, by checking difference between consecutive terms is constant.

The answer to this question is that it depends. The distance of Ken’s house from the park cannot be determined without knowing the distance of the school and the pet shop from the park, and other factors such as terrain, local roads, and traffic can also affect the distance between Ken’s house and the park.

Distance is the amount of space between two points. It is a physical quantity that can be measured in various units such as meters, kilometers, miles and light-years. Distance can be calculated using the formula d = s × t, where d is the distance, s is the speed, and t is the time.

Ken lives at a point between the school and the pet shop, so it is impossible to answer this question without knowing how far away the school and the pet shop are from the park. If the park is close to the school or the pet shop, then Ken’s house would be close to the park, but if the park is further away from the school or the pet shop, then Ken’s house would be further away from the park. Therefore, the distance of Ken’s house from the park cannot be determined unless the distances of the school and the pet shop from the park are known.

In addition, other factors such as terrain, local roads, and traffic can also affect the distance between Ken’s house and the park. For example, if there is a hilly terrain between Ken’s house and the park, then the distance between them may be greater than if the terrain were flat.

The answer of the given question based on finding  the area of the shaded sectors the answer is  approximately 18.8 + 4.2 = 23.0 square units.

An angle is geometric figure formed by the two rays or lines that share common endpoint, called  vertex. The rays or lines are often referred to as arms or sides of angle

We need to know the central angles of each sector. We can find these angles by using the formula:

angle = (arc length / radius) * (180/π)

where π is pi, approximately equal to 3.14.

Therefore, we can use trigonometry to find angle EOB:

sin(EOB) = EB/OA

sin(EOB) = 10.4/8

EOB = sin^-1(10.4/8)

EOB ≈ 56.7° degrees

Since angle EOA is a right angle, we know that angle AOB is 90° degrees, so angle AOE is 90 - EOB = 33.3° degrees.

Now, we can find the area of each sector using the formula:

area = (angle/360) * π * r²

Area of shaded sector ADE:

angle AOE = 33.3° degrees

radius = OA = 8

area = (33.3/360) * π * 8²

area ≈ 18.8 square units

Area of shaded sector EBC:

angle EOB = 56.7° degrees

radius = EB/2 = 5.2

area = (56.7/360) * π * 5.2²

area ≈ 4.2 square units

Therefore, the total area of the shaded sectors is approximately 18.8 + 4.2 = 23.0 square units.

A cat would probably have consumed about 6 meals if its activity level had been around 9.

A linear equation is a relation between two variables in which one is dependent on the other in such a manner that changing one of the variables causes the change in another variable "linearly".

The above statement can be represented mathematically as,

y=mx+b

where m represents the rate of the change and c is the initial value of the equation.

Let x stand for activity level and y for the number of meals consumed. Therefore:

y = 0.23x + 4.1

For an activity level of 9, we will put x as 9:

y = 0.23(9) + 4.1 = 6.17

Thereby, we can say that If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

Answer: a rational number

Answer:

  9

Step-by-step explanation:

You want the value of the constant 'a' in the solution y=√(a+b·cos(πx)) to the differential equation y'=3sin(πx)/(2y) with initial condition y(1/2) = 3.

Substitute the initial condition into the equation for y:

  y = 3 . . . . when x = 1/2

  y = √(a +b·cos(πx))

  3 = √(a +b·cos(π/2)) = √a

  3² = a = 9

The value of a is 9.

Additional comment

The value of 'b' is -3/π.

It can be found by putting the equation for y in the original differential equation, and solving for b.

The top of the ladder is sliding down the wall at the rate of 1.5 ft/s.

Given: A ladder is 25 ft long and is leaning against the wall of a house.

The base of the ladder is sliding away from the house at the rate of 2 ft/sec.

Asked: How fast is the top of the ladder sliding down the wall when its base is 15 feet from the wall?

Let the distance of the top of the ladder from the wall be x ft.

Then we have,

x² + y² = 25² (by Pythagoras theorem)

Differentiating both sides with respect to time t,

we get, 2x(dx/dt) + 2y(dy/dt) = 0 ...(1)

Given dx/dt = 2, and x = 15 ft.

⇒ 2(15)(dx/dt) + 2y(dy/dt) = 0

⇒ 30 × 2 + 2y(dy/dt) = 0 (substituting the given values)

⇒ 2y(dy/dt) = - 60⇒ dy/dt = - 30/ y

The negative sign indicates that y is decreasing (getting smaller) with time.

The values of y are negative because it lies below the level of the ground.

Substituting the value of x = 15 in the equation x² + y² = 25², we get

15² + y² = 25²

⇒ y² = 25² - 15² = 400

⇒ y = - 20

Substituting the values of dy/dt and y in the above equation, we get,

dy/dt = - 30/ (- 20)

dy/dt = 1.5 ft/s

The exponential regression equation that fits the given data points is y = [tex]4*3^(x-1).[/tex]

The exponential regression equation that fits these data is y = 4*3^(x-1). To calculate this, we need to first calculate the parameters a and b for the equation y = a*b^x. We can do this by finding the natural logarithm (ln) of both sides of the equation.

ln(y) = ln(a*b^x)

ln(y) = ln(a) + ln(b^x)

ln(y) = ln(a) + x*ln(b)

We can now calculate the parameters a and b by plotting the points (x, ln(y)) and performing a linear regression on the points.

ln(4) = 0.602

ln(8) = 2.079

ln(27) = 3.526

ln(85) = 4.443

ln(250) = 5.52

ln(600) = 6.398

The linear regression equation is ln(y) = 0.175x + 0.602. We can now solve for the parameters a and b by using the linear regression equation.

ln(a) = 0.602

a = e^0.602

a = 4

ln(b) = 0.175

b = e^0.175

b = 3
