Answer:
A, D, H
Step-by-step explanation:
The function models exponential decay because the factor is 0.8 which is < 1
0.8 means 80% of the previous which is a decay of 100 - 80 = 20%
50(0.8^x)
50(0.8²)
= 32
Answer:
2/3
Step-by-step explanation:
Answer:
[22 x 21] / 2=231 or "c"
Step-by-step explanation:
First problem:
cos (theta)=1
Using the inverse cosine function, you get theta = 0.
Now we find tan 0 = 0
cot(theta) = 1/tan(theta) = 1/0
Division by zero is undefined, so the answer is d. undefined
Second problem:
cos (theta)=1
Use the inverse cosine function.
theta = 0°
Answer: c. 0°
