Answer:
Step-by-step explanation:
Given
Required
Find
First, we calculate the inverse function
Express f(x) as y
Swap the positions of x and y
Solve for y: Add 4 to both sides
Square both sides
Divide both sides by 2
Express y as an inverse function
Next, solve for:
Substitute 6 for x
Answer: Expected value of playing the game is $0.
Step-by-step explanation:
Since we have given that
Total number of colored chips = 20
Number of blue chips = 2
Number of purple chips = 4
Number of green chips = 7
Number of red chips = 7
Amount of prize he gets for blue chip = $10
Amount of prize he gets for a purple chip = $5
No amount is given for red or green
Amount he had to pay = $2
So, Expected value of playing the game is given by
Hence, Expected value of playing the game is $0.
The height of the triangular base of the pyramid is calculated through the equation,
h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of x is 30°. Substituting,
h = (cos 30°)(18 in)
h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.

Answer:
She need to walk 31/75 miles to school.
Step-by-step explanation:
It is given that,
Sofia has walk miles to school. She has already walk of a mile.
We need to find how much farther does she need to walk.
Total distance =
Let she has to walk x distance to school.
Hence, she need to walk 31/75 miles to school.
