Answer:
30
Step-by-step explanation:
4.50=15%
30=100%
check;
30*0.85=25.5
30-25.5=4.50
Given:
The function is .
To find:
The function .
Solution:
We have,
Substitute f(x)=y.
Interchange x and y.
Divide both sides by 3.
Taking power 4 on both sides.
Subtract 7 from both sides.
Substitute .
Therefore, the correct option is C.
Answer:
-14-2i
Step-by-step explanation:
-9-i+(-5-i)
collect like terms(real-real, imaginary-imaginary)
=(-9-5)+(-i-i)
=-14-2i
You would use the equation y = A(1+r)^t
A = Original amount = 200
r = interest rate = 0.042 (when converted from percent to decimal)
t = time = x
Plug them in and you get the model: y = 200(1+0.042)^x
or just simplify the parentheses to (1.042)
