A power function of the form ()=^ f(x)=ax^b is used to model the wind chill , in degrees Fahrenheit, with wind speed
x, in miles per hour, when the temperature is 30°

A) It is the wind chill when the temperature is 30°
30 °F and the wind speed is 0 miles per hour.

B)It is the wind chill when the temperature is 0°
0° F and the wind speed is 0 miles per hour.

C) It is the wind speed in miles per hour when the temperature is 30° and the wind is 0.

D) It is the wind speed in miles per hour when the temperature is 0° and the wind chill is 0°.

the answer is a

step-by-step explanation:

39.00 x 24 = total installment price

carrying installment price - cash price

needed to save the .00/

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
