Hello!
First you have to find what the temperature was at the 3 stages
It started at 87
Then went down 10
87 - 10 = 77
Then up 17
77 + 17 = 94
Then you take the difference from the current temperature from the lowest temperature
94 - 77 = 17
The answer is D
Hope this helps!
Answer:
x=6
Step-by-step explanation:
We can write this as a ratio
x 9
---- = --------
10 15
Using cross products
15x = 10*9
15x = 90
Divide by 15
15x/15 = 90/15
x =6

Answer:
Option C) The value of a is correct, but the value of b is incorrect.
Step-by-step explanation:
z = 8(cos(300°) + isin(300°))
z = 8cos(300°) + 8isin(300°)

So we can see that a = 4 which is correct but b =
and b in the question says it is b
so its incorrect so Option C is your answer.
