Ahot air balloon rose from a height of 100 m to 400 m in 3 minutes what was the ballons rate of change

100 m/minute

Step-by-step explanation:

We are given that

Initial height of balloon=100 m

Final height of  balloon=400 m

Time taken =3 minute

We have to find the rate of change of balloon height.

Change in height of balloon=Final height-initial height=400 -100= 300 m

Rate of change of balloon height=

Hence, the rate of change of balloon height is 100 m/minute.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
