Answer:
Given:
Principal= $5,000
After 3 years, Amount= $7,100
After 8 years, Amount= $10,350
Step-by-step explanation:
Interest after 3 years= $7,100- $5,000
=$2,100
Interest in last 5 years= $10,350- $7,100
=$ 3,250
Difference between first 3 years and last 5 years= $3,250- $2,100
=$1,150
Amount= Principal*
10,350=5000
=
2.07=
=1+
1.095-1=
0.095*100=r
r=9.5%
Average rate=
=$475

Answer:
Step-by-step explanation:
To find the inverse of a function, first let y= f(x).
f(x)= 2x +3
Let y= f(x).
y= 2x +3
Next, make x the subject of formula.
y -3= 2x
Divide both sides by 2:
Replace x with f⁻¹(x) and y with x to obtain the inverse of the function.
Thus, the 2nd option is correct.
