F a ball with an original velocity of zero is dropped from a tall structure and it takes 7 seconds to hit the ground, what veloc
ss7ja [257]
For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time

Vf = Vi + at. 

Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*

All you have to do then, is simplify to get 68.6 m/s which is B.

The prices of houses in Tennessee have been on a steady incline for the last several years. If the average price of a house has
sveticcg [70]

Answer:

The average price of a house last year was = $124,423.96

Step-by-step explanation:

Let the average price of houses in Tennessee last year in dollars be = x

This year the increase percentage in average price was = 8.5%

The change in average price can be calculated in dollars as:

⇒ 8.5\%\ of\ \textrm{Last year average price}

⇒ 0.085\times x

⇒ 0.085x

New increased average price in dollars can be calculated as:

\textrm{Last year average price + Increase in average price}

⇒ x+0.085x

⇒ 1.085x

The new increased average price actually is = $135,000

So, we have,

1.085x=135000

Dividing both sides by 1.085

\frac{1.085x}{1.085}=\frac{135000}{1.085}

∴ x=124423.96

Thus average price of a house last year was = $124,423.96
