Answer:
x(t) = 37cos(70o)t and y(t) = –16t2 + 37sin(70o)t
Step-by-step explanation:
It would be equal to −4x^3-14x^2-16x
I think your answers are a b and c but I’m not exactly sure, sorryy:)
Answer:
$1,085
Step-by-step explanation:
Data provided in the question:
Amount inherited and invested i.e principle = $31,000
Annual return for Mark on savings account = 2.9% = 0.029
Annual return for Charles on CD = 6.4% = 0.064
Now,
The Interest earned by Mark in 1 year = principle × Rate × Time
= $31,000 × 0.029 × 1
= $899
The Interest earned by Charles in 1 year = principle × Rate × Time
= $31,000 × 0.064 × 1
= $1,984
Therefore,
More Money that Charles have than Mark = $1,984 - $899
= $1,085
Answer:
Step-by-step explanation:
- Principal = $480
- Interest rate = 7% compounded
- Compound number = 4 per year
- Time = 9 years
<u>Final amount is:</u>
- 480*(1 + 0.07/4)^(9*4) =
- 480(1.0175)^36 =
- $896.36
