Angle between 16 and 18 = 90 + 55 = 145°

$d= \sqrt{16^2+18^2-2*16*18*cos(145^o)}= \\ \\ \sqrt{256+324+471.83}= \sqrt{1051.83} \approx 32$

Colton earns $7 per hour plus $1.50 for each pizza delivery. The expression 7h + 1.50d can be used to find the total earings aft

Rina8888 [55]

Since the expression 7h + 1.50d can be used to find the total earnings. We just need to substitute the given data to the expression to solve the problem.

7(15) + 1.50(8)
105 + 12 = 117

Colton's total earnings after working 15 hours and making 8 deliveries is 117 dollars.

Rina8888 [55]

Answer:

Step-by-step explanation:

Rate of change is the slope

Function A:

Slope = change in y/Change in x

= (9-3)/(3-0) = 6/3 = 2

Function B:

Clearly the slope is 3

(y = mx + c, m is the slope)

Rate of change of B is more than A
