I want to believe the equation is,
f(x) = -5/x
This can be written as;
f(x) = y
y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
= 5x⁻²
Derivative at x=11,
dy/dx = 5(11)⁻²
= 5/(11²)
= 5/121
So, the derivative of f(x) = -5/x at x=11 is 5/121.
Answer: height= 7.24 inches
Step-by-step explanation:
-4.5 if you were to graph the linear function.
After 2 hours, she was (62 mph -50 mph)*2h = 24 miles behind her trip average, so she had to make that distance up in the last 3 hours. That is, her average for the last 3 hours was (24 mi)/(3h) = 8 mph more than her trip average.
Jiamin averaged 62+8 = 70 mph for the last 3 hours of her trip.
