Mathematics
1 answer:
Vera_Pavlovna [14]3 years ago

Answer:

38.13 ft squared

Step-by-step explanation:

Since it is half of a circle we first find the area of a normal circle then divide by two.

So to find the area of  a circle it is pi times radius squared which in this case it would be 3.14 times 9 = 28.26

Then since it is a half circle we divide by two so

28.26/2 = 14.13

Then to find the area of the triangle we do 4 times 6 which is 24.

now we add the two which is 14.13 + 24 which is

38.13

Fine the slope of the line through each pair of points . (-8,-20),(5,2)
kozerog [31]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-8, -20) and (5, 2). Substitute:

m=\dfrac{2-(-20)}{5-(-8)}=\dfrac{22}{13}

Answer: The slope is \dfrac{22}{13}

What is the equation of the line that passes through the point (-5,2) and has a slope of 4/5
dedylja [7]

Answer:

4x - 5y + 30 = 0

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here $m = \frac{4}{5} $ and $ (x_1 , y_1) = (-5,2) $.

Substituting in the equation we get

$ (y - 2) = \frac{4}{5} (x + 5) $

$ \implies 5y - 10 = 4x + 20 $

$ \implies 4x - 5y + 30 = 0 $

2) Lucy spent $15, 500 to purchase a new car this year. Lucy can expect her car to depreciate at a rate of 7% per year.
Lelechka [254]

Answer:

<u>Equation: V = C * (1 - r)^t</u>

<u>Answer: $ 8,066.37</u>

Step-by-step explanation:

Let's recall that depreciation on a car can be determined by the formula:

V = C * (1 - r)^t , where:

V is the value of the car after t years,

C is the original cost

r is the rate of depreciation

t is the number of years of utilization of the car

Therefore, we have:

V = C * (1-r)^t

V = 15,500 * (1 - 0.07)⁹

V = 8,066.37 (rounding to the next cent)
