How do I figure the pythegeroen theorm

The Pythagorean theorem is a^2+ b^2= c^2.

The variables, A and B are the legs of the triangle and c is the hypotenuse of the triangle.

We can use the Pythagorean theorem to find any side of the triangle when two of the sides of the triangle is known.

Hope this helps!

The quadratic function h(t) = -16.1? + 150 models a ball's height, in feet, over time, in seconds,

Sliva [168]

<h2>Hello!</h2>

The answer is: The first graphic representation.

We are given a quadratic equation, meaning that it could be two possible solutions for the exercise, however, we are talking about time, so we have to consider only the obtained positive values.

Let's make the equation equal to 0 in order to find the values of "t"

$h(t) = -16.1t^2 + 150$

$0=-16.1t^2+150$

$16.1t^2=150$

$t^2=\frac{150}{16.1} =9.32$

$t=+-\sqrt{9.32} =+-3.05$

$t1=3.05$

$t2=-305$

So, discarding the negative value, we can use the possitive value to find the correct graphic representation.

To find the correct graphic representation we must take into consideration the following:

- We must remember that the sign of the coefficient of the quadratic term (t^2) will define if the parabola opens downward or upward.

From the given quadratic (or parabola) equation we have:

$a=-1$

$b=0$

$c=150$

So, since the coefficient of the quadratic term is negative, the parabola opens downward.

- Since we are looking for a graphic that represents the change in height over time, we need to look for a graphic that shows only positive values for the x-axis (time)

- We are looking for a parabola which y-axis intercept is equal to 150.

Therefore, the graphic representation of the quadratic function that models a ball's height over time is the first graphic representation.

Have a nice day!

Briana bought a lot of snacks from Dollar General last night for $193.84, not including tax. If the tax rate was 9%, how much di

lina2011 [118]

Answer:

17.4456 Pretty sure they want you to round up not sure

Step-by-step explanation:

I like to divide by 100 the get the rate for 1% and then multiply by the actual number in your case 9 you can use a calculator for this to make it easy and you can get it pretty simple this usually works for all percent's if you have multiple like 9.74 use the lowest percent .04 that way you can use it to find the rest I hope this helps :) lmk if you want me to explain more

A vertex can be the max or min. The vertex is the highest point or lowest point of a function.
