Answer:
D. 12.3 ft
Step-by-step explanation:
This problem requires the use of trigonometric ratios. This one specifically uses the cosine ratio as it provides the hypotenuse and is asking for the side that is adjacent to the angle.
cos(40°)=a/16
cos(40°)×16=a/16×16
cos(40°)×16=a
a=12.256 ft
The length of side a is D. 12.3 ft.
So you would plug in 0 for a from the beginning since this is numerical slope definition of a derivative
Answer:
-2.85
Step-by-step explanation:
I looked it up tbh
The mean is 7.5 you add up all the numbers and then divide by the amount of numbers there is
It’s (-8z^2 +8x +4y -2z)
Hope it helps
