19, 62 mi/h =ft/sec
20.40 m/s = ft/min
21. 100 ft/s =mi/h
22.2 qt/s = gal/min
23.8 qt/min =fl. oz./sec
24.40 m/s =km/h

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

246

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
