Answer:

-6x^2+4x+5

Step-by-step explanation:

g(x)+f(x)=(-8x^2-3x+5)+(2x^2+7x)

=-8x^2-3x+5+2x^2+7x

=-8x^2+2x^2-3x+7x+5

=-6x^2+4x+5

Write an addition expression and a subtraction expression, each with a value of 2.4 X 10 the power of negative 3.
Zolol [24]

Okay so first figure out what 2.4 times 10 with the power of negative 3 is.

2.4 times 10 is 24 and 24 to the power of 3 is 13,824

so an addition problem could be 5,986+7,838= 13,824

then you could do for a subtraction problem 23,789- 9,965 = 13,824

I hope this helped you. (;

If a car has tires with a diameter of 28 inches and is traveling at 55 mph, how fast are its tires spinning, in rpm^ prime s (re
Aleksandr-060686 [28]

Answer:

The tires are spinning at 660.49 revolutions per minute.

Step-by-step explanation:

The speed of the tires (v) is the same that the speed of the car, so to find the angular velocity of the tires we need to use the equation:

\omega = \frac{v}{r}

Where:

r: is the radius of the tires = d/2 = 28 inches/2 = 14 inches

\omega = \frac{55 mph}{14 inches*\frac{1 mile}{63360 inches}} = 2.49 \cdot 10^{5} \frac{rad}{h}*\frac{1 h}{60 min}*\frac{1 rev}{2\pi rad} = 660.49 rpm              

Therefore, the tires are spinning at 660.49 revolutions per minute.

   

I hope it helps you!
