Check the picture below, so it reaches the maximum height at the vertex, let's check where that is

h(t)=64t-16t^2+0 \\\\[-0.35em] ~\dotfill\\\\ \textit{vertex of a vertical parabola, using coefficients} \\\\ h(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+64}t\stackrel{\stackrel{c}{\downarrow }}{+0} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left(-\cfrac{ 64}{2(-16)}~~~~ ,~~~~ 0-\cfrac{ (64)^2}{4(-16)}\right)\implies \stackrel{maximum~height}{(2~~,~~\stackrel{\downarrow }{64})}

A Fruit Stand sells 6 oranges for $3.00 and grapefruit for $2.40 people buy 10 oranges and 11 grapefruits much does the fruit sp
Harlamova29_29 [7]
<span>The <u>correct answer</u> is:

$31.40.

Explanation<span>:

Since 6 oranges cost $3.00, we can divide to find the cost of one orange:

3.00/6 = $0.50. Each orange costs $0.50.

If ten oranges are bought, this would cost 10(0.50)=$5.00.

Each grapefruit costs $2.40; 11 of them would cost 11(2.40) = 26.40.

Together the total cost is $5+$26.40 = $31.40.</span></span>

List the fractions and decimals in order from least to greatest: -0.6,-5/8,-7/17,-0.72
zhuklara [117]
First, let's convert all of these numbers to decimal form:

(This will make it much easier to compare.)

- 0.6, - 0.625, - 0.4117, - 0.72

Now we can list them from least to greatest!

-0.4117, - 0.6, -0.625, -0.72

And don't forget to convert the selective decimals that we converted earlier back into fractions!

Therefore, the final list would be:
- 7/17, - 0.6, - 5/8, - 0.72

Hope this helps!
