explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction
Tomtit [17]
Think:  You're treating the numerator and the denom. in precisely the same way.  In doing so you are NOT changing the value of the fraction, only the appearance.

Example:  start with 2/3.  Mult num. and den. both by 7:  14/21.

2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.

A ball is thrown into the air from an apartment balcony and falls to the ground. The height of the ball, h metres, t seconds aft
andriy [413]

Answer:

1+2\sqrt{2} seconds

Step-by-step explanation:

When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:

0=-5t^2+10t+35 \\\\-5(t^2-2t-7)=0

Plugging this into the quadratic equation, you get:

t=\dfrac{2\pm\sqrt{4+28}}{2}= \\\\\dfrac{2\pm4\sqrt{2}}{2}= \\\\1\pm2\sqrt{2}

Since the time must be positive, it takes the ball 1+2\sqrt{2} seconds to hit the ground, or around 3.828. Hope this helps!
