Answer:
Y=240sin(180πx)
Step-by-step explanation:
All i really looked at was the last part 180πx since it was running 90 cycles per second my natural instinct was to do this
90 times 2π and i got 180π
Answer:
The scale factor is 3 and the translation is (-8,2)
Step-by-step explanation:
(I'm not very good at translation/dilation but since you asked, I'm pretty sure this is the answer!)
56.25 minutes
Explanation: to find how long it takes to run one mile, divide 50 minutes by 8 miles.
50/8 = 6.25
Then you can multiply 6.25 by 9 to find the answer.
9 x 6.25 = 56.25 minutes
If your asking for the answer it’d be
x= -1
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have

![t=1\ year\\ I=\$75\\ P=\$2,500\\r=?](https://tex.z-dn.net/?f=t%3D1%5C%20year%5C%5C%20I%3D%5C%2475%5C%5C%20P%3D%5C%242%2C500%5C%5Cr%3D%3F)
substitute in the formula above
solve for r
