Answer:

C(t)=30+3.5t

Step-by-step explanation:

Time increases by 2, the average difference in the cost is approximately 7.

So if d is the common difference of the function modeling this relationship, then  2d≈72.

Therefore,  d≈ 7/2 = 3.5

Since the initial cost of the land is 30 thousand dollars, the function that best models its cost t years since 1990 is C(t)=30+3.5t

A window is being replaced with tinted glass. The plan at the right shows the design of the window. Each unit length represents
PolarNik [594]
The answer is $911.68.

After a little research on the internet, I found the design of the window.
First, you need to find the area of the window which is a composite figure made up of a rectangle and a circle. So, the total area (A) is the sum of the area of the rectangle (A1) and the area of the circle (A2).

Area of the rectangle with length l and width w is:
A = l * w
According to the image, l = 5 ft and w = 4 ft.
A1 = 5 * 4 = 20 ft²

Area of the circle with radius r is:
A = r²π
According to the image, r = 2 ft.
A2 = 2² * 3.14 = 12.56 ft²

The area of the window is:
A = A1 + A = 20 ft² + 12.56 ft² = 32.56 ft²

<span>The glass costs $28 per square foot, so to replace the glass will cost:
</span>32.56 ft² * $28/ft² = $911.68

Question #7
Sever21 [200]

Answer:

The area is 56.7 square inches

Step-by-step explanation:

Given

See attachment for corner shelf

Required

The area

The corner shelf is a quadrant with radius;

r = 8.5in

The area of a quadrant is:

Area = \frac{\pi r^2}{4}

So, the area of the corner shelf is:

Area = \frac{\pi * 8.5^2}{4}

Area = \frac{\pi * 72.25}{4}

Area = \pi * 18.0625

Take \pi as 3.14

Area = 3.14 * 18.0625

Area = 56.7 -- approximated
