24th is the answer, you just double the 12 because it’s both a number 3 and 4 go into

Write the equation of the function whose graph is shown. y = (x + )2 +

Deffense [45]

Quadratic form is given in the form
$y= ax^{2}+bx+c$ , where a, b, and c are constants

We substitute the value (8, 12) and (5,3) in turn

$12= a(8)^{2}+b(8)+c$
$12=64a+8b+c$ ... Equation 1

$3=a(5)^{2}+b(5)+c$
$3=25a+5b+c$ ... Equation 2

Equation 1 - Equation 2 gives
$39a+3b=9$ , we call this Equation 3

We also know that (5, 3) is the turning point of the curve, where the value of $x$ is given by $x=- \frac{b}{2a}$
Substitute $x=5$
$5=- \frac{b}{2a}$
$10a=-b$
$b=-10a$ ... Equation 4

Substitute Equation 4 into Equation 3
$39a+3b=9$
$39a+3(-10a)=9$
$39a-30a=9$
$9a=9$
$a=1$

Now we need to work out the value of $b$ and $c$

Substitute $a=1$ back into equation 4
$-10a=b$
$-10(1)=b$
$b=-10$

Substitute $a=1$ and $b=-10$ into either equation 1 or equation 2

$64a+8b+c=12$
$64(1)+8(-10)+c=12$
$64-80+c=12$
$c=12+80-64$
$c=28$

Hence the equation of the quadratic curve is
$y= x^{2} 10x+28$

Factor completely p^4-81

kobusy [5.1K]

$(p^{2}-9)(p^{2}+9) = p^4+9p^{2}-9p^{2}-81 = p^{4}-81$

The left side of the equation is what you get if you apply the "foil" method to the middle. This is the first step. Now the left-hand side is only partially factored, because you can still factor one of the remaining terms. Notice that one of the terms on the left has a similar form to that of the original question p^4-81. You can apply the same method I did to that term and then you will have fully factored p^4-81. You should have 3 factors in the end. Hope this helps!

A square-based pyramid has a base side length of 10 feet and a height of 15 feet.

madam [21]

By the pythagorean theorem we know that.
s2 = r2 + h. ...
since r = a/2.
s2 = (1/4)a2 + h2, and.
s = √(h2 + (1/4)a2)
This is also the height of a triangle side.
I don’t know the answer but this might help.
