Answer:
x ≈ 73.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos39° = 
= 
( multiply both sides by x )
x × cos39° = 57 ( divide both sides by cos39° )
x = 
≈ 73.3 ( to the nearest tenth )
The correct answer is f^-1(x)=1/2x+2.
1. Substitute y for f(x). ( y=2x+4 )
2. Interchange the variables x and y. ( x=2y-4 )
3. Swap the sides. ( 2y-4=x )
4. Move the constant to the right. ( 2y=x+4 )
5. Divide both sides by 2. ( y=1/2x+2 )
6. Use substitution to substitute f^-1(x) for y.
Thus the inverse is f^-1(x)=1/2x+2
What is the third quartile of the following data set? 24, 20, 35, 39, 28, 42, 25, 29, 44, 21, 37?
aivan3 [116]
First, put the numbers in order. 20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44
Find the median, the median is 29.
Find the median of the 5 numbers AFTER 29 which is 39, therefore, 39 is your third quartile.
Answer: The volume is approximately 62.8
Step-by-step explanation:
v= 
* r^2 *h
v= 3.14 * 4 * 5
v= 62.8
Answer:
5,236 in
Step-by-step explanation:
volume for head: 2144.66
volume for torso: 2714.34
volume for arms: 376.99
add it up and equals 5235.99, round it up to 5,236
