Answer:
C. 16x+9=4x
Step-by-step explanation:
Answer:
I think it is -24t+20 if you want to simplify
Step-by-step explanation:
I will get you started.
Let sin x = u
Then 7sin^2x -14sinx+2=-5 become
7u^2 - 14u = - 5
7u^2 - 14u + 5 = 0
Steps:
1. Solve for u.
2. Back- substitute for u.
3. Take the arcsin on both sides to find the angle(s).
You finish.
Answer:
a median
b center
Step-by-step explanation:
The middle value of a set of numbers is the median
The mean is the average value and the range is the largest minus the smallest.
This value is a measure of the center ( or a measure of the middle)
The range is a measure of the spread
30 + 70 + D = 180
100 + D = 180
D = 80°
