Answer with Step-by-step explanation:
We are given that an equation of curve
We have to find the equation of tangent line to the given curve at point
By using implicit differentiation, differentiate w.r.t x
Using formula :
Substitute the value x=
Then, we get
Slope of tangent=m=
Equation of tangent line with slope m and passing through the point is given by
Substitute the values then we get
The equation of tangent line is given by
This is required equation of tangent line to the given curve at given point.
Since one knot is 1.15 mph.
We multiply 35 time 1.15, which equals 40.25 mph.
Then we subtract. 175 - 4.25 = 134.75
Round, and you'll get 135mph
Therefore, your answer is 135mph
Unit rate= $$/lbs.
2.40/12=0.2
Your unit rate is $0.20

You have the formula. Put in the numbers and solve for r.
The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B
