Answer:

Part A.

w = √(d^2 - l^2)

Part B.

w = 6ft

Step-by-step explanation:

length l = 8ft

diagonal d = 10ft

width w = ?

we can see it as a Trangle, so using a Pythagorean theorem,

d^2 = l^2 + w^2

w = √ (d^2 - l^2)

w = √ (10^2 - 8^2)

w = √ (100 - 64)

w = √ 36

w = 6

Luda [366]

Answer: In 1 minute, the temperature goes up 50 degrees.

Step-by-step explanation:

This is the rate of change in this graph because 50 degrees is in 1 minute, so we divide 50 by 1. We get 50, so we add 50 to 50 and 100, and so forth. The answer is In 1 minute, the temperature goes up 50 degrees.
