The answer is 81 feet. This is because the maximum height is the y-value of the vertex since the vertex is the maximum point. So, it is 81 feet

At a supermarket, the price of yellow onions dropped from $0.58 per pound to $0.43 per pound.

Answer:

a. 25.9% b. $.76 per pound

Step-by-step explanation:

For part a. the formula for percent decrease is

% dec = $\frac{orig-new}{orig}*100$

We are solving for % dec. Filling in:

% dec = $\frac{.58-.43}{.58}*100$ simplifies to

% dec = $\frac{.15}{.58}*100$ which gives us, rounded to one decimal place:

% dec = 25.9%

For part b. we are going to use that percent decrease and fit it into a new equation to solve for the new price of tomatoes when we know the original price. Filling in:

$25.9=\frac{(1.03-new)}{1.03}*100$ which could be written instead as

$25.9=\frac{(1.03-new)100}{1.03}$

Now you can see what will happen on the right when we divide by 100...they cancel out. That looks like this, when we divide both sides by 100, as we must because this is an equation:

$\frac{25.9}{100}=\frac{(1.03-new)100}{(1.03)(100)}$

Simplifying on both sides:

$.259=\frac{1.03-new}{1.03}$

Now we will multiply both sides by 1.03:

.26677 = 1.03 - new and

-.76323 = -new so

the new price is .76 per pound

If BC = 6 and AD = 5, find DC.<br><br> A) 4<br> B) 4.5<br> C) 7.2

We have three similar triangles, because each has a right angle and shares an angle. Let's write the angles in order: opposite to short leg, long leg, hypotenuse.

CAB similar to BAD similar to CBD

Or as ratios,

CA:AB:CB = BA:AD:BD = CB:BD:CD

We also know

AC = AD + CD

(AD+CD):AB:CB = BA:AD:BD = CB:BD:CD

(AD+CD)/CB=CB/CD

We have CB=6, AD=5 and seek x=CD.

$(5 + x)/6 = 6/x$
