As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others
8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^
Answer:
The equation to find the number of groups can be formed is given as:
where represent the number of groups that can be formed.
We get on solving
Step-by-step explanation:
Number of 4th grade students who become cheerleader = 22
Number of 5th grade students who become cheerleader = 26
Number of cheerleaders in each cheer leading groups = 8
We need to divide the total number of cheer leaders into groups of 8.
Let represent the number of groups that can be formed.
Total number of students who want to become cheerleaders =
So, equation to find the number of groups can be given as :
⇒
⇒
Thus,a total of 6 cheer leading groups can be formed.
Answer: f(x^-1) = x/5 - 3/5
Step-by-step explanation:
1. Replace f(x) with y
2. Swap the positions of x and y to make x = 5y + 3
3. Solve for y by subtracting 3 from both sides and dividing each side by 5
Well first you have find out how many miles she drove in march. To find that you have to divide 825 by 3. That equals 275. Well if she drove 4 times more you take 275 x 4 and that equals 1100. She drove 1100 miles.
Answer:
B) -|x + 3| = 3
D) |x + 3| + 6 = 3
Step-by-step explanation:
A) |x + 3| = 3
B) -|x + 3| = 3
Divide by -1
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
C) |x + 3| + 3 = 3
Subtract 3 from each side
|x + 3| + 3-3 = 3-3
|x + 3| = 0
D) |x + 3| + 6 = 3
Subtract 6 from each side
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
