Answer:
Step-by-step explanation:
- Initial height is 2 in
- Height after 5 weeks is 8 in
<u>Rate of change is</u>
<u>So the equation is:</u>
Correct option is D
The slope of machine 1 is 0.3. And machine 2 is 3/8. Hope this helped
Remark
Let the amount invest = x
(1/3 x) * 5/100 + (1/2 x) * 5.5/100 = 735 Multiply numerators and denominators together on each side of the plus sign.
5x/300 + 5.5x / 200 = 735
Multiply both sides of the equation by 600 to get rid of the denominators.
(5x/300)*600 + (5.5x/200)*600 = 735 * 600
(5x * 2) + 5.5x * 3 = 441000
10x + 16.5x = 441000 Combine the like terms on the left.
26.5 * x = 441000 Divide by 26.5 on both sides.
x = 441000/26.5
x = 16641.51 = invested amount <<<<< answer
Check
1/3 * 5/100 * 16641.51 = 277.36
1/2 * 5.5/100*16641.51 = 457.63
The total = 735 which is what it should be.
D is the function that is graphed
