Solve the equation. <br> ×-9=-6× + 5

Serggg [28]

The answer is x=2. You add 6x to both sides to get 7x-9=5 then add 9 to both sides to get 7x=14. From there, you divide by 7 on both sides to get x=2.

Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall is 60 feet is 0.25 √6

aleksandrvk [35]

Answer:-1)The three sets of approximation of time will be

Time taken to fall tennis ball from height of 60 m =35.41014 s ≈35.410 s (to the nearest thousandth)

≈35.41s (to the nearest hundredth)

≈35.5 seconds(to the nearest tenth)

2)Time by the ball to hit the ground =35.5 seconds

Step-by-step explanation:

Time taken to fall tennis ball from height of 60 feet = 0.25 √60 s

So,time taken to fall tennis ball from height of 1 foot =0.25√60 divided by 60= $\frac{0.25\sqrt{60} }{60}s$

We know that 1 m = 0.3048 foot

⇒60 m =60×0.3048=18.288 feet

therefore, Time taken to fall tennis ball from height of 60 m = 18.288 ×time taken to fall tennis ball from height of 1 foot= $\frac{0.25\sqrt{60} }{60}\cdot18.288=35.41014\ s$
