Answer:
Step-by-step explanation:
200(1+r)⁵⁻³ = 200(1+r)² = 800
(1+r)² = 4
1+r = 2
r = 100%
800(1+r)⁷⁻⁵ = 800·2² = 3200
Answer:
3.25 +7.25m
Step-by-step explanation:
The cost of membership in Jump Rope Gym can be modeled by ...
total cost = initial fee + m × (monthly fee)
j = 6.50 +17.50m
Likewise, the cost for Run Run Run Gym is ...
r = 9.75 +24.75m
Then the savings by joining the Jump Rope Gym is ...
r -j = (9.75 +24.75m) -(6.50 +17.50m) = 3.25 -7.25m . . . .savings
I believe the answer is 87.5
Harry's trainer recommends Harry drink
8*(8 oz) = 64 oz
of water per day.
A pint is 16 oz, so this amounts to
(64 oz)*(1 pt)/(16 oz) = 4 pt
of water per day.
By drinking 3 full bottles of water, Harry drank
3*(1 1/4 pt) = 3 3/4 pt
of water.
This amount of water (3 3/4 pt) is less than the 4 pt recommended by the trainer. Harry's claim that he drank the full amount is not true.
A cubic polynomial function has 3 zeroes, which is why it is cubic. The student says there are 4 zeroes, which is not possible.
