Answer:

Step-by-step explanation:
Given



Required
The solution
Differentiate

Next, we solve for c1 and c2
implies that; x = 1 and y = 0
So, we have:

--- (1)
implies that: x = 1 and y' = e
So, we have:


--- (2)
Add (1) and (2)


Divide both sided by e

Divide both sides by 2

Substitute
in 

Rewrite as:

Multiply both sides by e

So, we have:



Answer:
Subtraction.
Step-by-step explanation:
As the question has said, 7/8 ft shorter than table which means you must substract it from the table's height.
For example :
if a stool is 7/8 ft longer than table which means you must add up the table's height
Answer:
There are four different possible outcomes: both coins are heads, the red coin is heads and the blue coin is tails, the red coin is tails and the blue coin is heads, or both coins are tails. Each outcome has equal probability. So the probability of both being heads is 1/4.
