Answer:
- 3.68 feet using given equation (wrong)
- 12.5 feet using correct equation
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 <em>full revolutions</em>, so is back where it started — at 12.5 feet above the ground.
A: {-4, -2 -1, 2}<br>
B: {-4, 4}<br>
C: {-3, -2, 0, 2}<br>
D: {-4, -2, -1, 0, -2}

Answer:this is soooo compli
Step-by-step explanation:
The interest Raymond will pay this month is $54.98
What does APR mean?
APR means annual percentage rate, which means that since we are computing monthly interest, the annual rate which is the whole 12 months needs to be divided by 12 to ascertain the equivalent monthly interest rate
monthly interest=21.99%/12
What is the monthly interest amount in dollars?
The monthly interest amount in dollars is determined as the monthly interest rate multiplied by the credit card balance at the end of the month
monthly interest=$3,000*21.99%/12
monthly interest=$54.98

$20,000 is between $15,000 and $49,999, so we'll use the interest rate of 6.5% (see row 3)
r = 6.5% = 6.5/100 = 0.065
We'll use the decimal form of the interest rate as it is most common for financial math problems.
P = 20,000 is the amount deposited
t = 1 year is the amount of time
We will plug those values into the formula
i = P*r*t
to get the following:
i = P*r*t
i = 20000*0.065*1
i = 1300
So Mark earns $1,300 in simple interest each year.
A mixed number and one and two-ninths.
Hope this helps! :D
