A car travels at an average speed of 64 miles per hour. how many miles does it travel in 3 hours and 45 minutes

ELEN [110]

64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.

Find the inverse function of f(x)=4x-8

kipiarov [429]

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2

-3•e^(2m-5)-3=-27 how to solve

zzz [600]

Answer:

m = 3.53972077085

Step-by-step explanation:

-3 × $e^{2m - 5}$ - 3 = -27

Subtracting -3 from both sides of the equation gives;

-3 × $e^{2m - 5}$ = -24

Dividing by -3 on both sides of the equation gives;

$e^{2m - 5}$ = 8

Let 2m - 5 = x

xloge = 3log2

x = $\frac{3log2}{loge}$ = 2.0794415417

So,

2m - 5 = 2.0794415417

2m = 2.0794415417 + 5

2m = 7.0794415417

Dividing by 2 on both sides of the equation gives:

m = 3.53972077085
