3-3 Additional Practice 1. Two linear functions are shown below. Which function has the greater
rate of change?

Function A

Step-by-step explanation:

Function A rate of change:

Using two given pairs of values, (4, 32) and (8, 44):

Rate of change = ∆y/∆x

= (44 - 32)/(8 - 4)

= 10/4

Rate of change = ⁵/2

Function B rate of change:

Using two points on the line, (2, 4.5) and (4, 6.5):

Rate of change = ∆y/∆x

= (6.5 - 4.5)/(4 - 2)

= 2/2

Rate of change = 1

Function A has the greater rate of change

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
