Step-by-step explanation:

If the question is to factorize

$x^4-17x^2+16\\\\x^4-x^2-16x^2+16\\\\=x^2(x^2-1)-16(x^2-1)\\\\=(x^2-1)(x^2-16)\\\\=(x+1)(x-1)(x-4)(x+4)\\$

Sophia is dilating a figure. One of her pre-image points with coordinates (-3, 5) has an image with coordinates (-9, 15). If one

Galina-37 [17]

The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3

Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)

You're uncle is having a new roof installed in his house. The roof is a square pyramid. The side length of the base of the roof

Kaylis [27]

Answer:

The height of the roof in his house is 72.43 ft.

Step-by-step explanation:

The volume of square pyramid is :

$V=\frac13 Bh$

B= area of the base.

h= the height.

Given that,

The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.

The side length of the base of the roof is 28 feet.

Since the base of the roof is square in shape.

The area of the square is = side²

The area of the base is =(28×28) square feet

=784 square feet

Assume the height of the roof be h ft.

Then, the volume of the roof is = $\frac13 Bh$

$=\frac13 \times 784 \times h$ square feet.

According to the problem,

$\frac13 \times 784 \times h= 18929.3333$

$\Rightarrow h=\frac{18929.3333\times 3}{28}$

$\Rightarrow h\approx 72.43$ ft.

The height of the roof in his roof is 72.43 ft.
