Answer:
$46875.
Step-by-step explanation:
We have been given that Dr. Drake buys a sailboat for 125000. He borrows the money at an APR of 7.5% for five years.
We will find total interest after 5 years by using simple interest formula.
, where,
A= Amount after T years.
P= Principal amount.
r= The annual interest rate (in decimal form).
T= Time in years.
First of all we will convert our given interest rate from percent to decimal form.
Now let us substitute our given values in above formula.
To find the amount of total interest we will subtract principal amount from 171875.
Therefore, the total interest after 5 years will be $46875.
Answer:
X=4.35
Step-by-step explanation:
Let's start solving
3(x-3)^2-162=0
Add 162 to both sides
3(x-3)^2=162
Square root both sides
√3(x-3)=√162
1.73(x-3)=12.727
Open the bracket
1.73x-5.19=12.727
Add 5.19 to both sides
1.73x=7.5327
Divide both sides by 1.73
x=4.35
The answer to the given question is letter "B".
We will compute first individually
The distance at 1 min. =60
At 2 minutes= 60 +0.4*60 = 84
At 3 minutes = 84 +0.4*84 = 117.6
At 4 minutes = 117.6 + 0.4*117.6 = 164.64
At 5 minutes = 164.64 + 164.64*0.4 = 230.5
At 6 minutes = 230.5 + 230.5*0.4 = 323
Since the answer is letter "B" when we calculate using this equation in B, we will arrive at the same answer at 6 minutes:
D = 323
