Answer:
r = -189
Step-by-step explanation:
-13 - 8 = r/9
- 21 = r/9
r = 9 * -21
r = -189
24.08 because 60.20 divided by 5 is 12.04 then you gotta multiply by 2 because she’s not paying for only herself so it’s 24.08
The equation of the tangent to the curve at the point corresponding to the given value of the parameter will be x + y = c.
<h3>How to calculate the tangent of the parameter curves at a point?</h3>
The curves are given below.
x = t⁵ + 1 and y = t⁶ + t
Then differentiate the functions with respect to t, then we have
...1
and
...2
Divide equation 2 by equation 1, then we have

Then the slope of the equation at t = −1, then we have
dy/dx = [6(-1)⁵ + 1]/[5(-1)⁴]
dy/dx = (-6+1)/5
dy/dx = -5/5
dy/dx = -1
Then the equation of the tangent line will be
y = -x + c
x + y = c
Where c is a constant.
