You are right good job and now i'm going to do the same
first i'm gooing to work with the dollars 1.00 + 1.00 =2.00 now 2.00 + 1.00 =3.00 then you count by 30's 30,60,90 now add 3.00 + 0.90 = 3.90
F(C) = 9/5C + 32
I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32
inverse...
x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9
Sooooo
F(C) = 5/9C - 160/9
I believe it is C. The quadratic function.
The amount A when the principal P is compounded continuously is given by the formula :
Here r is rate of interest and t is time .
In the question P=1600 ,r=6.5%=0.065 ,t= 6 years
Substituting these values in the formula
A= 1600(1.48)
A=2363.17
Balance after 6years is $2363.17
If 42% of paint is white to get the result we just have to finid 42% of 18.
42% of 18 = 0.42*18=7.56$ - its our result
