61•bcThe answer to this question
(a) With a unit rate of 8, repeated (iterated) 72 times, we can simply multiply 8 by 72 to get the net change: 8 × 72 = 576 fish.
(b) For the unit rate (i.e. rate of change per time - minutes in this case) we can simply divide the total water pumped out by the total time it took to perform this. So: 48 ÷ 8 = 6 gallons/min.

Answer: 880 cm
Step-by-step explanation:
Given: Radius of the hula hoop = 35 cm
Hula hoop is circular in shape
Then, Circumference =
, where r = radius
Now , Circumference of hula hoop = 
Now , the distance the hula hoop rolls in 4 full rotations = 4 × (Circumference of hula hoop)

Hence, the required distance = 880 cm
Answer:
slope = - 14
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 8) and (x₂, y₂ ) = (- 3, - 6)
m =
=
= - 14
