Answer:

Step-by-step explanation:

I believe the answer is 17.

Simplify

=17

Now,

Consider point O at zero on the number line.

Mark a point A such at number 4 such that OA= 4

Draw a perpendicular AB at point A of unit length.

Join AB

Taking radius of length AB draw an arc to intersect the number line at C.

Finally, OC=\sqrt{17}

Thus proving the answer is 17 or $\sqrt{289} = 17$

A cube has a side length of inch. It would take blocks with a side length of inch to fill the cube. It would take blocks with a

Complete question:

A cube has a side length of 1/3 inch.It would take _ blocks with a side length of 1/6 inch to fill the cube.

B)It would take _ blocks with a side length of 1/9 inch to fill the cube.

Answer:

a) 8 blocks

b) 27 blocks

Step-by-step explanation:

Here we need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = $\frac{1}{3}$

Therefore,

V = $(\frac{1}{3})^3$

V = = $\frac{1}{27}$

Volume of the cube is $\frac{1}{27}$

To find volume of the block, let's use the formula:

V = a³

V = $(\frac{1}{6})^3$

V = $\frac{1}{216}$

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= $\frac{\frac{1}{27}}{\frac{1}{216}}$

$= \frac{1}{27} * 216$

= 8

It would take 8 blocks with a side length of 1/6 inch to fill the cube.

B) Here we also need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = $\frac{1}{3}$

Therefore,

V = $(\frac{1}{3})^3$

V = = $\frac{1}{27}$

Volume of the cube is $\frac{1}{27}$

To find volume of the block, let's use the formula:

V = a³

V = $(\frac{1}{9})^3$

V = $\frac{1}{729}$

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= $\frac{\frac{1}{27}}{\frac{1}{729}}$

$= \frac{1}{27} * 729$

= 27

It would take 27 blocks with a side length of 1/9 inch to fill the cube.

20 points and crown determine the product of each set of polynomials (2x-3)(4x+5)=0

bonufazy [111]

Remember to make the polynomials to equal zero, one or the other polynomial must equal zero. So...

2x-3 = 0

2x= 3

x=3/2

and

4x+5 = 0

4x = -5

x = -5/4

So the answers are x=3/2 and x = -5/4

Hope this helps!

Which of the following describes the graph of y = StartRoot negative 4 x minus 36 EndRoot compared to the parent square root fun

RoseWind [281]

Answer:

stretched by a factor of 2, reflected over the y-axis, and translated 9 units left

Step-by-step explanation:

The given function is $y=\sqrt{-4x-36}$

We can rewrite this function by factoring -4 in the radicand to get:

$y=\sqrt{-4(x+9)}$

We further simplify the square root of 4 to get:

$y=2\sqrt{-(x+9)$

The parent function is $y=\sqrt{x}$

When we compare to the parent function, there is a stretch by a factor of 2, reflection over the y-axis, and translation 9 units left

The last option is correct

Try to answer the following question without running the code in Python: If we run the following line: y = int(3 * '4') what is

LenKa [72]

Answer:

444.

Step-by-step explanation:

The '4' is considered to be a string so if you print y you would get 444. The int means 'integral, ( I believe).
