Answer:
they are both divisible by 4
so you could write
4 (5 + 4)
Step-by-step explanation:
You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15
Answer:
1/4x = 15/16
Step-by-step explanation:
1/4x = 15/16
Hey there!
First, we will multiply -100 by a.
-100 x a = -100a
Now we have:
-100a x 56
Let’s multiple this as well.
-100a x 56 = -5600a
Your answer is -5600a.
Hope this helps!

Explanation:
To prove x^m · x^n=x^m+n, let's assign numbers to x, m and n
let x = 2
m = 3, n = 4
x^m · x^n = 2^3 . 2^4
x^m+n = 2^(3+4)
Solve each of the above seperately and comparew the answer:



This expression x^m · x^n=x^m+n has been proved to be equal
