The correct answer is 30+100u. Hope this helps!!
Answer:
f(3) = 7
Step-by-step explanation:
Using the recursive formula and f(1) = - 3 , then
f(2) = f(1) + 5 = - 3 + 5 = 2
f(3) = f(2) + 5 = 2 + 5 = 7
<u>Given</u>:
The triangle ABC is a right triangle.
The length of AC = 25, the length of AB = 7 and the length of BC = 24
We need to determine the ratios of sin C, cos C and tan C.
<u>Ratio of sin C:</u>
Using the trigonometric ratio, the ratio of sin C is given by

where
and 
Thus, we get;

Substituting the values, we get;

Thus, the ratio of sin C is 
<u>Ratio of cos C:</u>
The ratio of cos C can be determined using the trigonometric ratio.
Thus, we have;

where
and 

Substituting the values, we get;

Thus, the ratio of cos C is 
<u>Ratio of tan C:</u>
The ratio of tan C can be determined using the trigonometric ratio.
Thus, we have;

where
and 
Thus, we have;

Substituting the values, we get;

Thus, the ratio of tan C is 
Answer:
Yes, this graph represents a function
Step-by-step explanation:
The function passes the vertical line test, which tests for if any input has more than one unique output by moving a vertical line from left to right. If the vertical line doesn't pass 2 or more points at a time, then the function is indeed a function.
