Total $19.75
Adding 5%
Taking away 20%
1). $19.75 x 0.20(20%) = 3.95
3.95 + 19.75 = 23.7
2). $19.75 x 0.05(5%) = 0.9875
0.9875 + 23.7 = 24.6875
= 24.6875
Answer:
A
Step-by-step explanation:
The values of sin (x/2) = 4/√17, cos (x/2) = 1/√17 and tan (x/2) = 4.
<h3>What is Trigonometry?</h3>
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.
Here, cos x = -15/17 (given)
we know, cos x = 2cos²x/2 - 1
cos²(x/2) = (cos x + 1)/2
cos²(x/2) = (-15/17 + 1)/2
cos²(x/2) = 1/17
cos (x/2) = 1/√17
then, sin (x/2) = √(1- cos²(x/2))
sin (x/2) = √(1 - 1/17)
sin (x/2) = √16/17
sin (x/2) = 4/√17
and tan (x/2) = sin (x/2) / cos (x/2)
tan (x/2) = 
tan (x/2) = 4
Thus, the values of sin (x/2) = 4/√17, cos (x/2) = 1/√17 and tan (x/2) = 4.

Answer:
The average rate of change is 10.
Step-by-step explanation:
Since the average rate of change is the slope of a line, you'd solve this problem by finding the slope.
First, you can start by using the
method.
Plug in the points (0,10) and (1,20).

Therefore your answer is 10.
