D, y-y1=m(x-x1)
^^^^^^^^^^^^^^^
Answer:
the answer is c: s=40(1.1)^m, s=20(1.15)^m
Step-by-step explanation:
in option A, (0.10) and (0.15) make it exponential decay rather than exponential growth like it's supposed to be.
In option B, the rate of growth is supposed to be on the exponent, not the sales themselves in the equation
option c is correct I just finished the test
option d has the same mistake as a and b combined
<span>.09X+.08(7,000-X)=588
.09X+560-.08X=588
.01X=588-560
.01X=28
X=28/.01
X=2,800 AMOUNT INVESTED @ 9%.
7,000-2,800=4,200 AMOUNT INVESTED @ 8%
PROOF:
.09*2,800+.08*4,200=588
252+336=588
588=588</span>
Answer:
3. w=P/2-L
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for w:</u>
- P=2(l + w)
- P/2 = 2(l + w)/2
- P/2 = l + w
- P/2 - l = l + w - l
- P/2 - l = w
- w = P/2 - l
<u>Correct answer choice is:</u>
