Just calculating the differential. Step by step:

If you want to know where the tangent has no slope:
Answer:
Step-by-step explanation:
6/9+x=7/10
x=7/10-6/9
when adding fractions both denominators must be equal, we’ll make them 90
x=(7/10)(9/9)-(6/9)(10/10)
x=63/90-60/90
x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3
x=(3/3)/(90/3)
x=1/30
The surface area of the cylinder to the nearest tenth is: 628.3
The surface area without rounding is: 628.32
Pentagons are and example.
