Answer:
The correct option is C) 
Step-by-step explanation:
Consider the provided ordered pairs.
The function will be exponential function if the ratio of y value remains the same.
Consider the option
Option A: 
The ratio of 1/4 and 1 is 1/4 but the ratio of 1/3 and 1/4 is not 1/4.
Therefore, option A is incorrect.
Option B: 
The ratio of 1/4 and 1 is 1/4 but the ratio of 1/9 and 1/4 is not 1/4.
Therefore, option B is incorrect.
Option C: 
The ratio of 1/4 and 1/2 is 1/2, the ratio of 1/8 and 1/4 is 1/2
Similarly the ratio of 1/16 and 1/8 is 1/2,
Therefore, option C is correct.
Option D: 
The ratio of 1/4 and 1/2 is 1/4 but the ratio of 1/6 and 1/4 is not 1/4.
Therefore, option D is incorrect.
Answer:

Step-by-step explanation:
Now for question, first find the percentage of balls that passed inspection
How to find percentage?
whatever
- - - - - - - - - - - - - - - - - - - x 100
The total of that whatever
Therefore in this case, your whatever is the golf balls
48
----------- x 100
60
= 80%
Now since now u know, 80percent of the golf balls will pass inpection
Now u have 2500, how many will pass? So just
2500 x 80%
= 2000
Answer:
Step-by-step explanation:
Complementary angles are angles that add up to 90°.
We have C and D as complementary.
Their sum is:
Substitute values and solve for x:
- 8x + 5x - 1 = 90
- 13x = 90 + 1
- 13x = 91
- x = 91/13
- x = 7
