Answer: option A. the surface of a flat plane.

Justification:

A plane in geometry is an infinite surface that does not have curvature, which means it is flat

It is an idealization and it does not have thickness and is unlimited in width and length. Those are the properties of a plane.

Here you have some examples that may represent the idea of a plane:

1) The surface of a hardcover book

2) The surface of the floor of a house

3) The surface of a wall

4) The surface of a flat mirror.

So, the clue to distinguish the correct answer is the word flat.

Rgarding the other options, the B. the edge of a desk describes a line, the C. describes a curve, and the D. describes a point.

A new car is purchased for $49,000 and over time its value depreciates by one half every 5 years. What is the value of the car 2

vovikov84 [41]

Principal: $49,000

Depreciation Rate: 50%

Depreciation Time: 5 years

Exponential Function: y = 49,000 (0.50)^x

Plug it in: y = 49,000 (0.50)^4

0.5^4= 0.0625

0.0625 x 49,000 = 3062.5

Value of Car after 20 years: 3062.5

Now, we need to find out how much the car decreases in ONE year.

Half of 3062.5 = 1531.25

1531.25/5 = 306.25

3062.5 - 306.25 = 2756.25

Value of car after 21 years: $2756 ---> 2800 (nearest hundred dollars my bad)

Hope this helps! Have a great day!

The combined area of the triangular faces = 4 * 1/2 * 4 * 6 = 48 sq ins

c
Surface area of the pyramid = 48 + area of base = 48 + 16 = 64 sq ins.
