The fuel economy of a car, measured in miles per gallon, is modeled by the function ƒ(s) = –0.009s2 + 0.699s + 12 where s repres

Kisachek [45]

Answer:

The maximum fuel economy of the car is 25.57225

Step-by-step explanation:

we are given

$f(s)=-0.009s^2+0.699s+12$

where

where s represents the average speed of the car, measured in miles per hour

So, we have to maximize f(s)

So, firstly we will find derivative

$f'(s)=-0.009*2s+0.699*1+0$

$f'(s)=-0.018s+0.699$

now, we can set it to 0

and then we can solve for s

$f'(s)=-0.018s+0.699=0$

$s=\frac{233}{6}$

To find maximum fuel economy , we can plug s into f(s)

$f(\frac{233}{6})=-0.009(\frac{233}{6})^2+0.699(\frac{233}{6})+12$

$f(\frac{233}{6})=25.57225$

So,

The maximum fuel economy of the car is 25.57225

What number should be added to both sides of the equation to complete the square in x^2 +8x=17

Papessa [141]

Hey there! :)
The formula for (a + b)^2 is a^2 + 2ab + b^2. In this case, x is a, and so b would have to be 4. We would need to add 4^2 = 16 to both sides of the equation to complete the square.
