storchak [24]

Answer:

$99/$115 x 100% = 86.086% of the original price

So 100% - 86.086

= 13.9 = 14%

Or you could just do (115 - 99) x 100 which gets the same answer.

How do the average rates of change for f(x) = -0.5x² and g(x) = -1.5x² over the interval -5 ≤ x ≤ -2 compare?

masha68 [24]

Pick an x-value between the interval givens. I’ll choose “1”. If you sub in one for both f(x) and g(x) you get that f(1) = -1.5 and g(1) = -0.5. Now you can divide f(1) by g(1) to get average rate of change. -1.5/-0.5 = 3.

Answer:

draw lines center to vertex
43.5 square inches
261 square inches

Step-by-step explanation:

Part A:

The area can be decomposed into triangles by drawing a line from the center to each vertex of the hexagon.

Part B:

The area of each triangle is given by the triangle area formula:

A = (1/2)bh

A = (1/2)(10 in)(8.7 in) = 43.5 in²

Part C:

The area of the table top is 6 times the area of one triangle:

surface area = 6(43.5 in²) = 261 in²
