1)
Y=(X-1)(x+8)(x+4)
Y=(x-1)(x^2+12x+32)
Y=x^3+12x^2+32x-x^2-12x-32
Y=x^3 + 11x^2 + 20x - 32

2)
Y=2(x-2)^3
Y=2(x-2)(x-2)(x-2)
Y=2(x-2)(x^2-4x+4)
Y=2(x^3-4x^2+4x-2x^2+8x-8)
Y=2(x^3-6x^2+12x-8)
Y=2x^3 - 12x^2 + 24x - 16

I’m pretty sure these are right. Hope it helps

If = {2,12,19,23,29} and b={2,23,34,40,45} then what is A∩B
exis [7]

9514 1404 393

Answer:

  A∩B = {2, 23}

Step-by-step explanation:

The intersection of two sets is the list of elements common to both.

  2 is found in both

  12, 19 are only in set A

  23 is found in both

  29 is only in set A

  34, 40, 45 are only in set B

The intersection of the two sets is {2, 23}.

Write the standard form of the equation of the circle with center (-5,-7) that passes through the point (7,5).
shutvik [7]

Answer:

(x + 5)² + (y + 7)² = 288

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The radius is the distance from the centre (- 5, - 7) to the point on the circle (7, 5)

Use the distance formula to calculate r

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, - 7) and (x₂, y₂ ) = (7, 5)

r = \sqrt{(7+5)^2+(5+7)^2} = \sqrt{12^2+12^2} = \sqrt{288}

Hence

(x - (- 5))² + (y - (- 7))² = (\sqrt{288})², that is

(x + 5)² + (y + 7)² = 288

Jared and Zach are practicing their free throws. Jared attempted x shots and made 75% of them. Zach attempted 10 more shots than
Alexandra [31]

The equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101

<h3>How to compute the equation?</h3>

From the information, Jared attempted x shots and made 75% of them. Zach attempted 10 more shots than Jared did and made 80% of them.

Therefore the equation that represents the situation will be:

= (0.75 × x) + 0.8(x + 10) = 101

= 0.75x + 0.8(x + 10) = 101.

Therefore, the equation that represents the situation will be (0.75x) + 0.8(x + 10) = 101
