The function is linear, so its rate of change is the same everywhere. That rate of change is the coefficient of the variable x, so is $2.90. Since the units of x are feet, and the units of P(x) are dollars, the rate of change $2.90 must be ...
... A. $2.90 per square foot
The answer is 30 laps. Don’t worry about anything else except for the laps and hours. Each hour have 60 minute so you just divide 1800 with 60 and get 30.
F(-1) = -2 -3x x (-1) = 3 and 3-5 is -2 :)

Answer:
angle B = 43°
side c = 12.31
side b = 8.40
Step-by-step explanation:
<u>Solve for angle B:</u>
sum of angles in a triangle = 180°
180 - (47+90) = 43°
<u>Solve for side c:</u>
sin(47) = opposite/hypotenuse
sin(47) = 9/c
.731 = 9/c
c = 12.31
<u>Solve for side b:</u>
a^2+b^2 = c^2
9^2 + b^2 = 12.31^2
81 + b^2 = 151.54
b = 8.40
