Answer:option A is the correct answer.
Step-by-step explanation:
The given triangle UVW is a right angle triangle. This is because one of its angles is 90 degrees. The sum of the two other angles is 180. To determine Cos U, we will apply trigonometric ratio.
Cos U = adjacent side/ hypotenuse.
Looking at the triangle with C as the reference angle,
Adjacent side = 12
Hypotenuse( always the longest side of the triangle) = 13
Therefore,
Cos U = 12/13
Answer:
72 yellow balls
Step-by-step explanation:
80% of 90 is (0.80*90) = 72 yellow balls.
Answer:
x = 
Step-by-step explanation:
3x+6 = 4x^2
4x^2 -3x -6 = 0
x = 
I need to know the distance.
speed= distance/ time
If you want to figure thier speed you need to divide the distance ( miles) by their time ( hours)
Recall Euler's theorem: if
, then

where
is Euler's totient function.
We have
- in fact,
for any

Now,

where the
are positive integer coefficients from the binomial expansion. By Euler's theorem,

so that
