Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how th

Dominik [7]

Answer:

We obtain equivalent fractions by multiplying both numerator and denominator by one constant:

Step-by-step explanation:

Equivalent fractions are fractions that represent the same quantity. We obtain equivalent fractions by multiplying both numerator and denominator by one constant:

$\frac{a}{b}=\frac{a*n}{b*n}\\$

For instance, in this case, we have these equivalent fractions for n=2,and n=3:

$\frac{1*2}{2*2}=\frac{2}{4}\\\frac{1*3}{2*3}=\frac{3}{6}$

So, if we place any given constant and multiply both numerator and denominator then we have equivalent fractions.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

Firlakuza [10]

Answer:

Time required to hit the ground is 7.9 s.

Step-by-step explanation:

The height of the rocket is given by

$y =- 16 x^2 + 119 x + 57$

For the time to hit the ground, put y = 0

$-16x^2+119x+57=0\\\\16 x^2 - 119 x - 57 = 0 \\\\x = \frac{119\pm\sqrt{14161+3648}}{32}\\\\x = \frac{119\pm133.45}{32}\\\\t = - 0.45 s, 7.9 s$

Time cannot be negative, so time to hit the ground is 7.9 s.
