The answer is 7/5. I attached the work below.
Answer:
9% fund: $ 210,000
13% fund: $70,000
Step-by-step explanation:
As she wants to have a $28,000 annual return for her $280,000 investment, she is expecting a return rate of 10%:
If we call x the proportion of the capital in the 9% fund, then (1-x) is the proportion of the capital in the 13% fund,and the return of the combination has to be the expected return of 10%:
Then, we know that 75% of the capital should be invested in the 9% fund and 25% in the 13% fund.
This correspond to a capital of:
9% fund: 0.75*$280,000 = $ 210,000
13% fund: 0.25*$280,000 = $70,000
First graph it
#1
Maximum height is the y coordinate of vertex
- (2,144)
Max height
- 144m
#2
Time is the x coordinate of vertex
- 2s
#3
- y is 0
x intercepts are the solutions
- (-1,0)U(5,0)
Take it positive
- t=5s
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
