A stone is thrown vertically upward from a platform that is 20 feet height at a rate of 160 ft/sec. Use the quadratic function h

Nutka1998 [239]

Check the picture below.

$\textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{-16}x^2\stackrel{\stackrel{b}{\downarrow }}{+160}x\stackrel{\stackrel{c}{\downarrow }}{+20} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\left(-\cfrac{ 160}{2(-16)}~~~~ ,~~~~ 20-\cfrac{ (160)^2}{4(-16)}\right) \implies \left( - \cfrac{ 160 }{ -32 }~~,~~20 - \cfrac{ 25600 }{ -64 } \right) \\\\\\ \left( 5 ~~~~ ,~~~~ 20 +400 \right)\implies (\stackrel{seconds}{5}~~,~~\stackrel{feet}{420})$

I don’t know how to figure out the ratio of the areas. The area for HGEF is 60.5 (121/2) and the area for JKLM is 378.125 (3025/

natima [27]

Answer:

25 : 4

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b , then

ratio of area = a² : b²

For the given figures the ratio of corresponding sides is

JK : EF = 20 : 8 = 5 : 2 , thus

ratio of areas = 5² : 2² = 25 : 4

Josh bought some cases of water. Each case has 12 water bottles.

Akimi4 [234]

Hello!

Equation D. t = 12c shows how many bottles of water Josh bought.

Explanation:

The first three equations would NOT give you the answer, because if you divide, you'll find out how many bottles are in each case.

If you subtract and add, it'll also result in the wrong answer, so D is the right equation.
