VARVARA [1.3K]

Answer:

\theta=24.4^\circ

Step-by-step explanation:

The formula you wrote has the fraction the other way around. You can find that the range​ of a projectile is in reality approximated by the equation x=\frac{v^2}{g} sin(2\theta)=\frac{v^2}{32ft/s^2} sin(2\theta), where we will use ft for distances.

From the given equation we have then \frac{x32ft/s^2}{v^2} =sin(2\theta), which means \theta=\frac{Arcsin(\frac{x32ft/s^2}{v^2})}{2} since the arcsin is the inverse function of the sin.

Since we have x = 170 ft and  v = 85 ft/s, we can substitute these values from the equation written, and we will have \theta=\frac{Arcsin(\frac{(170ft)(32ft/s^2)}{(85ft/s)^2})}{2}, and from now on we have just to use a calculator, obtaining \theta=\frac{Arcsin(0.75294117647)}{2}=\frac{48.84579804^\circ}{2}=24.4^\circ

What is the solution to this equation?<br> 7x + 3 = 10x - 5.4
stich3 [128]

Answer:

x=2.8

Step-by-step explanation:

7x+3=10x-5.4

Subtract 3 from both sides:

7x+3-3=10x-5.4-3

7x=10x-8.4

Subtract 10x from both sides:

7x-10x=10x-8.4-10x

-3x=-8.4

Divide both sides by -3:

\frac{-3x}{-3}=\frac{-8.4}{-3}

x=2.8
