Answer:
x=3 or x= -8
Step-by-step explanation:
Answer is 9 root3
this is because it is one of the special triangle: with special ration of 2x:root3x:1x
you could plug values into the sin formula as well.
9 cm is the smallest length since it is across from the 30° angle. so there fore 9 is 1x
x is 9.
root3x = 9root3
Answer:
a. this b>9 B. the first one C. the second one
Step-by-step explanation:
D is the first one
Steps to solve:
3 + x(-2) = 10
~Simplify
3 - 2x = 10
~Subtract 3 to both sides
-2x = 7
~Divide -2 to both sides
x = -3.5
Best of Luck!
Answer:
504 ways.
Step-by-step explanation:
In this case, order matters. If Amy were lead, Bob were record keeper, and Charles were researcher, that would be different than if Bob were lead, Charles were record keeper, and Amy were researcher. So, we will be using a permutation formula to compute.
The formula is n! / (n - k)!, where n is the total number of people (9), and k is the number you are selecting (3).
9! / (9 - 3)! = 9! / 6! = (9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (6 * 5 * 4 * 3 * 2 * 1) = 9 * 8 * 7 = 72 * 7 = 504 ways.
Hope this helps!
