By the Pythagorean theorem
.. 15^2 = 10^2 +a^2
.. 225 = 100 +a^2
.. 125 = a^2
.. √125 = a
.. 5√5 = a ≈ 11.18
The missing side length is 5√5 cm.

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
