Ralph owns a circular farm as shown. He is planning to fence a triangular pigpen ABC in the farm. Point M is the midpoint of the
Flauer [41]

Answer:

Total = \$942

Step-by-step explanation:

Given

A = (0,0)

C = (3,4)

See attachment for farm

Required

The cost of fencing the farm

First, calculate the radius of the farm.

The radius is represented with AC.

So, we have:

AC = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} ---- distance formula

So, we have:

AC = \sqrt{(0 - 3)^2 + (0 - 4)^2}

AC = \sqrt{(- 3)^2 + ( - 4)^2}

AC = \sqrt{9+16}

AC = \sqrt{25}

AC = 5

Hence:

r = 5 --- radius

Calculate the circumference of the circle

C = 2\pi r

C = 2 * 3.14 * 5

C = 31.4yd

If 1 yard costs $30, 31.4 yards will cost:

Total = 31.4 * 30

Total = \$942

Find the area of the trapezoid
nata0808 [166]

Answer:

15 + 23 = 38

38 x 9 = 342

342 x 1/2 (basically just dividing by 2) 171

Step-by-step explanation:

Formula of a trapezoid:

B1(base 1) + B2(base 2) x H(height) x 1/2(basically just dividing by 2)

In this case,

12 and 23 are your bases, 9 is your height.

A part-time house cleaner made $9258.13 last year. If he claimed himself as an exemption for $3650 and had a $5700 standard dedu
kari74 [83]

Once we sort through the tax terms, that's just

9258.13 - 3650 - 5700 = $ -91.87
A negative numbers mean the deduction and exemption sheltered all of his income, so he has $0 taxable income, choice D.

A triangle with constant base b and height h is changing with time where h(t)=3t +1. What is the rate of change of the area of t
Keith_Richards [23]

The rate of change of the area of the triangle when t=1 is also equal to 3.

<h3>Rate of change</h3>

Given the function of height of a triangle expressed as:

  • h(t) = 3t + 1

The rate of change is expressed as

  • dh/dt = 3

The rate of change of the area of the triangle when t=1 is also equal to 3.
