Answer:
a. 10.2 in²/in
10.02 in²/in
b. 10 in²/in
Step-by-step explanation:
The area of a square is given by the following function:
The average rate of change between two points a and b is:
a. For x = 5 and 5.2:
For x = 5 and 5.02
b. The instantaneous rate of change in area with respect to x is given by:
For x = 5
Y/9 = 32
y is being divided by 9.
You want y alone, so to undo the division by 9, multiply both sides by 9.
y/9 * 9 = 32 * 9
y = 288
Answer:
x does equal -2
Step-by-step explanation:
Substitue x = -2:
[5(-2) -2 = -12]
Simplify:
[-10-2 = -12]
Add/Subtract from left to right:
[-12 = -12]
Therefore:
x = -2
Answer: 1.8 kg
Step-by-step explanation: Because 55-3 ½ is 52 so you need to do to 53.8 minus what equals 52, which is 1.8.
