Let Z = measure of angle Z in terms of sin, cos, and tan.

sin Z = 9/15

cos Z = 12/15

tan Z = 9/12

You can reduce each fraction to the lowest terms if needed.

Evaluate 10C4. Type a numerical answer in the space provided. Do not type spaces in your answer.
SOVA2 [1]
10C4 represent the Combinations of 10 objects taken 4 at a time. 

The formula for nCr is:

nCr= \frac{n!}{r!(n-r)!}

In the given case, n=10 and r=4. Using these values we get:

10C4= \frac{10!}{4!(10-4)!} \\  \\ 
= \frac{10!}{4!*6!} \\  \\ 
=210

This means we can make 210 combinations of 10 objects taken 4 at a time.

Multiply y^2-16/2y . 5y/y-4
alisha [4.7K]
So, first we multiply the fraction by using the formula a/b times c/d= a times c/b times d
=(y^2-16) times 5y/2y(y-4)
Now, we cancel the common factor y
=(y^2-16) times 5/2(y-4)
Now, we factor 5(y^2-16)
We factor (y^2-16) first
y^2-16
Rewrite 16 as 4^2
y^2-4^2
Now, apply the formula x^2-y^2=(x+y)(x-y)
=y^2-4^2=(y+4)(y-4)
=5(y+4)(y-4)
=5(y+4)(y-4)/2(y-4)
Cancel the common factor y-4
=5(y+4)/2
Answer: 5(y+4)/2
