Answer:

X²-64 = 0

Step-by-step explanation:

(x = 8)\: (x =  - 8)= 0 \\= (x  - 8 )\:  \: (x + 8) \\ x ^{2} + 8x - 8x - 64 = 0  \\ x^{2} - 64 = 0 \\ mark \: brainliest

Answer:

y = x^2 - 64

Step-by-step explanation:

Hello!

We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.

<h3>Factored Form: y = a(x - h)(x - k)</h3>

The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.

  • y = a(x - h)(x - k)
  • y = a(x - 8)(x+ 8)

This will give roots 8 and -8 for x.

  • y = 1(x - 8)(x + 8)\\
  • y = x^2 - 64

A possible equation is y = x^2 - 64.

Which statements are true about a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4
tigry1 [53]

Answer:

- The area of the base of the pyramid, B, is 24 cm

- A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.

Step-by-step explanation:

Volume of a rectangular based pyramid = 1/3{Base area × Height}

Base Area = Length × Breadth

Volume = 1/3{(Length × Breadth) × Height}

Given a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4

centimeters by 6 centimeters

Base Area = 4cm × 6cm

Base area = 24cm²

If Height =9cm

Volume of the pyramid = 1/3 × 24 × 9

Volume = 24 × 3

Volume of the pyramid = 72cm³

If the shape is a prism, the volume will be base area × height

= 24 × 9

= 216cm³

It can be seen that volume of rectangular prism = 3 × volume of rectangular pyramid.

If you are given the graph of h(x) = log. x, how could you graph m(x) = log2(x+3)?
Agata [3.3K]

Answer:

Option (d).

Step-by-step explanation:

Note: The base of log is missing in h(x).

Consider the given functions are

h(x)=\log_2x

m(x)=\log_2(x+3)

The function m(x) can be written as

m(x)=h(x+3)           ...(1)

The translation is defined as

m(x)=h(x+a)+b           .... (2)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

On comparing (1) and (2), we get

a=3,b=0

Therefore, we have to translate each point of the graph of h(x) 3 units left to get the graph of m(x).

Hence, option (d) is correct.
