Answer:
2+2 equals 4
Step-by-step explanation:
If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay.
When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.
8x = 4x*2
This means the multiplier is 2
5y*2 = 10y
8*2 = 16
The missing values are 10y and 16
Answer:
C. 
Step-by-step explanation:
We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.
Law of cosines:
, where, a, b and c are sides opposite to angles A, B and C respectively.
Upon substituting our given values in law of cosines, we will get:








Now, we will use inverse cosine or arc-cos to solve for angle Z as:



Therefore, the measure of angle Z is approximately 51 degrees.
Answer:
9 times.
Step-by-step explanation:
56 multiplied by 9 is 504, and if you add another 56, the number would be greater than 512, so the answer is 9 times.
