There are still 9 candies. The color of them is besides the point.
The radius going through the tangent point is perpendicular to the tangent line, so ΔQRT is a right triangle.
QT²=QR²+RT²
QR and QS are both radii, so QR=QS=15
QT²=15²+36²
QT=39
Here we have to use the fact that the domain of the function is equal to the range of the inverse function and range of the function is equal to the domain of the inverse function .
The range of the function is given . It means, the domain of the inverse function is given .
Correct option is the last option .
Answer:
Yvonne's bill = $16.5
Step-by-step explanation:
let
Total of the bill = a
If they split the bill equally = a/3
Yvonne's bill = 3 + a/3
Victoria's bill = $12
Wanda's bill = $12
a = 3 + a/3 + 12 + 12
collect like terms
a - a/3 = 27
(3a - a )/3 = 27
2a/3 = 27
cross multiply
2a = 81
divide both sides by 2
a = 81/2
a = 40.5
Yvonne's bill = 3 + a/3
Yvonne's bill = 3 + 40.5/3
Yvonne's bill = 3 + 13.5
Yvonne's bill = $16.5
