Find the volume of the cube.
inna [77]

We will find the volume by multiplying length * width * height, like this:

10 cm * 3 cm * 2 cm = 60 cm^3

For ml, when we talk about volume, we know that the 1 ml = 1 cm^2, so the answer for ml is 60ml.

solve 5x^2-7x+2=0 completing the square. what is the constant added on to form the perfect square trinomial
kenny6666 [7]
Best to factor 5 out of the first 2 terms:

5x^2-7x+2=0  =>  <span>5(x^2 - [7/5]x)                          +2=0

Take half of [-7/5]:  That'd be -7/10.

Square 7/10, add it to  </span>5(x^2 - [7/5]x)                          +2=0  and then subtract it:


5(x^2 - [7/5]x)+ 49/100       -  49/100       )                  +2=0

Then we have   5(x- [7/10] )^2 - 49/100 ) + 200/100 = 0

                          5(x-7/5)^2  - 245/100 + 200/100 = 0
                           5(x-7/5)^2 - 45/100 = 0
Dividing all terms by 5,  x-7/5 = plus or minus sqrt( 9/100 )
                                       x-7/5 = plus or minus 3/10

Then one root is x = 7/5 + 3/10, or  x= 17/10  (answer #1)

The other is        x = 7/5 - 3/10, or x = 14/10 - 3/10, or x = 7/10  (answer #2)

The illustration below shows the graph of yyy as a function of xxx.
Alisiya [41]
  1. The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
  2. The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
  3. The greatest value of y is y = 4.
  4. The smallest value of y is y = -3.

<h3>How to complete the sentences?</h3>

By critically observing the graph shown in the image attached below, we can logically deduce that the slope of the graph of this function is equal to 0 for x, between x = -3 and x = -2.

Similarly, the slope of the graph of this function is also equal to 0 for x, between x = 3 and x = 4.

Based on the graph (see attachment), the greatest value of y is 4 while the smallest value of y is -3.

5. A rectangular pool ha a length that is 13 meters longer than its width. perimeter is74 meters. What is the width Its of this
gregori [183]
Good evening Brian,

For this problem, let's look at what we're given.  So we have a pool with a length that is 13 m (meters) longer than its width, and we're given the perimeter, or distance around the entire pool, which is 74 m.

We know that the pool has a rectangular shape and that the perimeter of a rectangle is <span>width + length + width + length ⇒ 2(W) + 2(L)</span>.

Given the information provided, we can rewrite the equation to fit this problem.  Since we're told that the length is equal to 13 m + the width, so we can represent the length as W +13 m.  We can now rewrite the perimeter equation to be:

2(w) + 2 (w + 13 m) ⇒ 2(w) + 2(w) + 2(13 m) ⇒ 4(w) + 26 m = 74 m.

We're down to one variable now so this should be easy.  Subtract 26 m from both sides,

4(w) = 48 m

Now divide each side by 4 in order to find the width.

w = 12 m

-Hope this helps!
