Answer:

vertex = (- 3, 24)

Step-by-step explanation:

Given a quadratic in standard form y = ax² + bx + c : a ≠ 0, then

The x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = - x² - 6x + 15 ← is in standard form

with a = - 1, b = - 6, thus

$x_{vertex}$ = - $\frac{-6}{-2}$ = - 3

Substitute x = - 3 into the function for corresponding value of y

y = - (- 3)² - 6(- 3) + 15 = - 9 + 18 + 15 = 24

vertex = (- 3, 24)

VOLLEBALL.Pick one volleyball skill and cover the most important content for learning that skill.

Cerrena [4.2K]

Answer:

The six basic volleyball skills are passing, setting, spiking, blocking, digging, and serving. Passing is often thought of as the most important skill in volleyball. If you can't pass the serve, then you won't ever put your team in a position to score a point. The importance of serving is often undervalued.

Hi could somebody help me

Assuming both vertical lines are parallel and assuming I'm supposed to find all the unmarked angles...

Angle C:

Supplementary Angles.

x+36=180

180-36=x

x=144

Angle B:

Corresponding Angles.

Angle B ≅ Angle C

144

Angle A:

360 degrees in a quadrilateral

36+144+81+x=360

261+x=360

x = 99

A quadrilateral has three angles that measure 90o , 100o, and 120o. Which is the measure of the fourth angle?

Reptile [31]

$360 - (100 + 90 + 120) \\ 360 - 310 = 50$
it measures 50

good luck

A group of students are planning a mural at a wall the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning

zvonat [6]

Answer: $46x^2+73x+15$

Step-by-step explanation:

The area of a rectangle can be calculated with the formula:

$A=lw$

l: the length of the rectangle.

w: the width of the rectangle.

The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.

Knowing that the dimensions of the wall are $(6x+7)$ by $(8x+5)$ , its area is:

$A_w=(6x+7)(8x+5)\\\\A_w=48x^2+30x+56x+35\\\\A_w=48x^2+86x+35$

As they are planning that the dimensions of the mural be $(x+4)$ by $(2x+5)$ , its area is:

$A_m=(x+4)(2x+5)\\\\A_m=2x^2+5x+8x+20\\\\A_m=2x^2+13x+20$

Then the area of the remaining wall after the mural has been painted is:

$A_{(remaining)}=A_w-A_m\\\\A_{(remaining)}=48x^2+86x+35-(2x^2+13x+20)\\\\A_{(remaining)}=48x^2+86x+35-2x^2-13x-20\\\\A_{(remaining)}=46x^2+73x+15$
