the vertex of the parabola is calculated by the formula

$\displaystyle\ ax^2+bx+c\quad ;\quad \boxed{x_0=\frac{-b}{2a} \ \ ;\quad y_0 =ax_0^2+bx_0+c} \\\\x_0=-\frac{-8}{2} =4 \quad ; \ \ y_0 =16-32-9=-25 \\\\\ \ Answer: Coordinates \ \ of \ the \ vertex \ of \ the \ \ parabola \ \ (4;-25)$

Can someone help? This is so hard

Answer:

#1 x = 31°

#2 x = 125°

Step by Step Explanation:

By the theorem of intersecting secants outside of the circle, we have:

$x=\frac{1}{2}(103\degree-41\degree)$

$\implies x=\frac{1}{2}(62\degree)$

$\implies \red{\bold{x=31\degree}}$

By the theorem of intersecting chords, we have:

$x=\frac{1}{2}(96\degree+154\degree)$

$\implies x=\frac{1}{2}(250\degree)$

$\implies \purple{\bold{x=125\degree}}$

HELP 20 POINTS!

Butoxors [25]

For the first blank where it asks for the perimeter, the perimeter is all the outside sides of a shape added up. So, 6 + 1 + 2 + 4 + 4 + 5 = 22.

For the second blank, you just multiply the entire perimeter by 5, so, 22 times 5=110.

For the third blank, it is basically the same as the previous question. The answer is 5.

For the fourth blank, it is the same perimeter as the first blank, but instead of centimeters, it is in k. So, 22k.

Hope this helped! :)

Q # 1 Graph the function Y = |X + 2| - 3

Svetllana [295]

First of all we know the Absolute Value Function that is:

$\left | x \right |= \left \{ {{x \ \ \ \ x \geq 0} \atop {-x \ \ \ \ x\ \textless \ 0}} \right.$

This is called the Parent Function of the Absolute Value Function.

From the equation:

$y=\left | x+2 \right |-3$

The term:

$\left | x+2 \right |$

means that the the Parent Function is shifted two units to the left.

On the other hand, the term:

$-3$

means that the function $\left | x+2 \right |$ is shifted three units downward. So the result is the graph shown below
