-125=5p
-125/5=p
-25=p
Therefore, p= -25
Answer:
A. 77.4
Step-by-step explanation:
<u>Linear approximation formula</u>
Given function:
Use the chain rule to differentiate the function.
Differentiate the two parts separately:
Put everything back into the chain rule formula:
.
The <u>linear approximation</u> at a = 8 is:
Finally, substitute x = 7.8 into the <u>linear approximation equation</u>:
Answer:
60 square units
Step-by-step explanation:
We can use Pythagoras to solve this as appropriately projecting lines from any point will form a triangle. The vertical and horizontal lengths of which can be read of from the axis.
