Mike drives 110 miles in 4 hours what his rate of change
1 answer:
Answer:
The rate of change is 27.5 miles per hour
Step-by-step explanation:
Given:
Distance driven by mike = 110 miles
Time taken by mike to drive 110 miles = 4 hours
To Find:
Rate of change=?
Solution:
The rate of change is also known as speed . Here we have to find the speed at which the mike drives
So we know that
Substituting the values
Speed =
Speed =27.5

Price elasticity is defined as 
.
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate
by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)
