Answer:
Option D.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
f(t) = a*sin (b*t +c) + d
Please, see attached picture below.
By looking at the picture with all the possible cases, we can tell that the correct option is D.
The function has a period of T = 6π
Max . Amplitude = 9
Min . Amplitude = -5
Answer:
$50
Step-by-step explanation:
We have been given an equation 
. We are supposed to solve our given equation for k.
We can rewrite our given equation as:
Let us multiply both sides of equation by 0.9.
Therefore, the value of the k is 0.6.
Answer: 40 times.
Step-by-step explanation:
If the probability in a sigle spin of getting the colour pink is p = 0.2
This means that in 0.2*100% = 20% of the spins we should see the colour pink.
Then, out of 200 spins, the 20% of 200 is
(20%/100%)*200 = 0.2*200 = 40
This means that out of 200 spins, in around 40 of them we will se the colour pink.
Fifteen because 208/26 = 8 and 223 - 208 = 15
