Apply the law of cosines. and solve for A

14^{2} = 11^{2} + 11^{2} - 2(11)(11)cos(A) \\ 
196 = 121 + 121 - 242cos(A)  \\ 
-46 = -242cos(A) \\cos(A) = 0.1900826446

 A = 79.04239272, or 79

What’s the square root of 108 a to the 7th power b to the 5th power
MissTica

Answer:

Step-by-step explanation:

Factor all the factors making up the square root.

108: 2*2*3*3*3

a^7: a*a*a*a*a*a*a

b^5:b * b * b * b * b

The rule for taking a square root of this is

For every pair, you get to take one number outside the root sign and throw the other one away.

2*3*a * a * a* b * b√(3*a * b)

6a^3b^2 * √(3*a*b)

At 1:00 PM, you have 24 megabytes of a movie. at 1:15 P.M., you have 96 megabytes. What is the download rate in megabytes per mi
sladkih [1.3K]
Megabyte difference = 96 - 24 = 72
time difference = 1:15 - 1:10 = 15 min.

Download rate would be: 72 / 15 = 4.8

So, Your Answer would be 4.8 mb/min

Hope this helps!
