Answer:
(f+g)(2) = 4
(f-g)(4) = 8
(f ÷g)(2) = 7
(f x g)(1) = 0
Step-by-step explanation:
We are given these following functions:


(f+g)(2)

At 

Then
(f+g)(2) = 4
(f-g)(4)

At x = 4

Then
(f-g)(4) = 8
(f ÷g)(2)

At x = 2

Then
(f ÷g)(2) = 7
(f x g)(1)

Then

So
(f x g)(1) = 0
Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³
Answer:
1) The mean is actually 31
2) True, the mean would be about 35.
3) True, the mean would change because more medals were added for the USA.
4) True, the mean would be effected because two is added. It results in a increase
Answer:
The answer to your question is Area = 50.27 m²
Step-by-step explanation:
Data
Area = ?
Diameter = 8 m
π = 3.1416
Formula
Area = πr²
Process
1.- Find the length of the radius
radius = diameter/2
- Substitution
radius = 8/2
- Result
radius = 4 m
2.- Find the area of the circle
Area = (3.1416) (4)²
Simplification and result
Area = (3.1416) (16)
Area = 50.27 m²
The Formula for the volume of a sphere is 
- r --> length of radius --> 2ft
<u>Volume</u> = 
The <u>volume is 33.51 cubic feet</u>
<u></u>
Hope that helps!
