Answer:

13.6

Step-by-step explanation:

We can use the pythagorean therom since we know the 2 side leanths and solve for the longest side of the triangle which is the rectangle cut diagonally

11^2+8^2=c^2

121+64=c^2

185=c^2

√185= √c^2

13.6=c

Hope that helps !

Answer:

The answer is G. y=2x-2

Step-by-step explanation:

y+6=2(x+2)

First you multiply 2 by what is in the parenthesis

y+6=2x+4

Next you get y by itself by subtracting 6

y=2x+4-6

Simplify

y=2x-2

Which two numbers add up to -19 and multiply to make 35

iris [78.8K]

x+y = -19
x*y = 35

x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437

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
