Answer:
x= 5y where y is no of revolutions and x is the distance traveled
Step-by-step explanation:
Let y be no. of revolutions and x be the distance traveled so the equation will be
x=5y
when y= 1 x=5 ft
when y=2 x=10 ft
when y=3 x=15 ft
when y=4 x= 20 ft
when y=8, x=40 ft
Answer:
and
Step-by-step explanation:
The equation of curve is
We need to find the equation of the tangent line to the curve at the point (-3, 1).
Differentiate with respect to x.
The point of tangency is (-3,1). It means the slope of tangent is .
Substitute x=-3 and y=1 in the above equation.
Divide both sides by 130.
If a line passes through a points with slope m, then the point slope form of the line is
The slope of tangent line is and it passes through the point (-3,1). So, the equation of tangent is
Add 1 on both sides.
Therefore, and .

Answer:
Emanuel did a mistake in her first step.
Step-by-step explanation:
The given expression is
Emanuel solve this problem but she did a mistake in her first step. She distributes negative sign with 1 and 2 both which is incorrect. We can write negative sign with either 1 or 2 but not both.
Correct steps are:
Step 1:
Step 2:
Step 3:
Therefore, she did a mistake in her first step.
