Assuming that by "16t2" you mean
:
First of all, let's compute the position at the two required times:


So, the ball traveled a total distance of
, during the time
.
The average rate of change is the ratio between these two:

Answer:
- 12x +9y ≥ 510
- y ≤ 2x
- y ≥ 25
Step-by-step explanation:
Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...
12x +9y ≥ 510
__
Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...
y ≤ 2x
__
Richie will walk at least 25 dogs, so ...
y ≥ 25
Answer:
Step-by-step explanation:
Given that:
Distance to friends's house = 1.8 miles
Time taken = 12 minutes
Since the rate is constant :
The rate Is related to distance and time :
The two variable equation which represents the equation is :
Speed = Distance / time
Step-by-step explanation:
g*f(x)=g(x+4)=(x+4)³
g*f(-3)=(-3+4)³
= 1³=1
