Answer:

3 2/3

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

Complete the multiplication and the equation becomes

The two fractions now have like denominators so you can add the numerators.

Then:

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 6 using

Convert to a mixed number using

long division for 11 ÷ 3 = 3R2, so

Therefore:

Abigail tosses a coin off a bridge into the stream below. The distance, in feet, the coin above the water is modeled by the equa
melomori [17]

Answer:

7 seconds

Step-by-step explanation:

Distance of the coin above the water is modeled by the equation

y=-16x^2+96x+112

where x is time taken to cover the distance

Now equating with zero.

0=-16x^2+96x+112\\\Rightarrow 16x^2-96x-112=0\\\Rightarrow x=\dfrac{-\left(-96\right)\pm \sqrt{\left(-96\right)^2-4\times \:16\left(-112\right)}}{2\times \:16}\\\Rightarrow x=7, -1

So, time taken by the coin to hit the water is 7 seconds.
