Answer:

the answer should be y=35 and x=27.8

The way you get this is you look at how angle D and A are the same for both triangles. given this, they are equal to each other. So you'd do 2y-5=65. You will get 35. 35=y, so substitute that in for your other equation. You will get 2x+35=90.6. solve that and you will get 27.8=x

Find the quadratic function that fits curve below. Select the correct answer.

raketka [301]

<h2>Hello!</h2>

The answer is:

The quadratic function that fits the given picture is:

$y=-3x^{2}+13x-5$

We can solve the problem and find the correct function that fits the curve below by finding which function intercepts the y-axis at -5 (we can see it from the picture), also, we need to look for a function that represents a parabola opening upwards. We need to remember that when a parabola is opening upwards, its quadratic term coefficient is negative.

So, we can see that from the given functions, the only function that represents a parabola opening upwards and its y-intercept is located at y equal to -5 is the second option:

$y=-3x^{2}+13x-5$

We have that :

$a=-3(negative)\\b=13\\c=-5(y-intercept)$

We can see that the quadratic term (a) is negative, and the quadratic function intercepts the y-axis at y equal to -5.

Hence, the answer is:

The quadratic function that fits the given picture is:

$y=-3x^{2}+13x-5$

Have a nice day!

The cylinder is 10 meters wide and the volume is 300 cubic meters what's the height of the cylinder?

daser333 [38]

Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
$V=A*h= \pi r^{2}*h$
You get an equation to count height:
$h= \frac{V}{ \pi r^{2} }$
h≈3.82 meters

You drop a pencil out of window that is 20ft above the ground. Use the formula V^2=64s, where V is speed and s is the distance f

gizmo_the_mogwai [7]

First you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times <span>the square root of 5
V=16 times </span><span>the square root of 5

also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V</span>
