Which numbers are perfect squares? Check all that apply.

blagie [28]

Answer:

16, 100, 1,

Step-by-step explanation:

A perfect square is a number multiplied by itself to get that number. So 16 would be 4*4 and 100 would be 10*10, then 1 would just be 1*1

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –

SVETLANKA909090 [29]

We have to identify the function which has the same set of potential rational roots as the function $g(x)= 3x^5-2x^4+9x^3-x^2+12$ .

Firstly, we will find the rational roots of the given function.

Let 'p' be the factors of 12

So, p= $\pm 1, \pm 2, \pm 3, \pm 4, \pm 6$

Let 'q' be the factors of 3

So, q= $\pm 1, \pm 3$

So, the rational roots are given by $\frac{p}{q}$ which are as:

$\pm 1, \pm 2, \pm 3, \pm 4, \pm 6, \pm \frac{1}{3}, \pm \frac{2}{3}, \pm \frac{4}{3}$ .

Consider the first function given in part A.

f(x) = $3x^5-2x^4-9x^3+x^2-12$

Here also, Let 'p' be the factors of 12

So, p= $\pm 1, \pm 2, \pm 3, \pm 4, \pm 6$

Let 'q' be the factors of 3

So, q= $\pm 1, \pm 3$

So, the rational roots are given by $\frac{p}{q}$ which are as:

$\pm 1, \pm 2, \pm 3, \pm 4, \pm 6, \pm \frac{1}{3}, \pm \frac{2}{3}, \pm \frac{4}{3}$ .

Therefore, this equation has same rational roots of the given function.

Option A is the correct answer.

The edges of a cube are 5 cm each and the diaganol of a face is approximately 7 cm what is the approximate area of the cross sec

xxTIMURxx [149]

Answer:

The approximate area is 35 square centimeters

Step-by-step explanation:

we know that

The cross section passing through the diagonal of opposite faces of the cube is a rectangle

the approximate area is equal to

$A=bh$

where

b is the diagonal of a face

h is the length side of the cube

we have

$b=7\ cm\\h=5\ cm$

substitute

$A=7(5)=35\ cm^2$
