Hello!
We have to find how fast the car goes a minute
To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour
This gives us 0.95 miles a minutes
3/4 is greater hope that helped
I hope that’s right. Sorry if I got it wrong. Have a good day!
Answer:
4123
Step-by-step explanation:
A=Pert,
where A is the balance of the account, P is the principal, r is the annual interest rate (as a decimal), and t is the time (in years). We are given that P=2800, r=0.043, and t=9. Substituting the values into the formula and using a calculator to evaluate, we find
A=Pert=2800e(0.043)(9)≈4123.16
