Answer:

Thus, our system of equation becomes,

x^2-y=0  and  y-2x=4

Step-by-step explanation:

Given equation : x^2=2x+4

We have to set up the given equation as a system of equations.

We can set an equation as a system of equations by placing its both side equal to a single variable term.

Consider the given equation x^2=2x+4.

since, the  given equation x^2=2x+4 has two sides right side and left side , let put them equal to a same variable y ,

then we get,

x^2=y and 2x+4=y

Thus, our system of equation becomes,

x^2-y=0  and  y-2x=4

\bf x^2=2x+4\implies 
\begin{cases}
y=x^2
\\\\
y=2x+4
\end{cases}\implies  y=y

DochEvi [55]
<span>The square is equal so all sides have equal sides. Soooo...

s2 (s squared) + s2 = 15 (squared)

15 x 15 = 225

225/2 = 112.5

Now you just have to get the square root. So go onto ur calculator. Which equals 10.606

The spherical container has a radius of 21 cm. What is the approximate volume of the container? Use 3. 14 to approximate pi. Rou
Gemiola [76]

Volume of a figure is the measure of the space that figure occupies. The approximate volume of the specified container is 87.92 cm³

<h3>What is the volume of sphere?</h3>

If the given sphere is of radius r units, then its volume is given as:

V=  \dfrac{4}{3} \pi r^3 \: \rm unit^3

For the given case, the radius of the sphere is given to be 21 cm, and the value of pi is instructed to be used  as 3.14

Thus, we have the volume of container as:

V = \dfrac{4}{3} \pi r^3 = \dfrac{4}{3} \times 3.14 \times 21 = 87.92 \: \rm cm^3{

Thus,

The approximate volume of the specified container is 87.92 cm³

Do the sides 4, 5, and 6 form a Pythagorean Triple?
NemiM [27]

Answer:

They do not form a Pythagorean Triple.

If it was a Triple,  4^2+5^2 should equal 6^2.

4^2+5^2=16+25=41

6^2=36

41≠26

It doesn't work, therefore it is not a Pythagorean Triple.

Solve x(x-1) (X-5) &lt;=O​
lara [203]

Answer:

x <= 0 or  1 = < x <= 5.

Step-by-step explanation:

First we find the critical points:

x(x - 1)(x - 5) = 0

gives x = 0, x = 1 and x = 5.

Construct a Table of values:

               <u>  x < 0 </u>  <u>x = 0 </u> 0<u>< x < 1</u>  <u>1 =< x <= 5</u>     <u>x = 5</u>

x                  <0        0          >0             <0           0

x - 1             <0       -1           >0              <0           0

x - 5            < 0       0          > 0             <0           0

x(x-1)(x-5)    < 0      0          >0              <0          0 

So the answers are x =< 0 or  1 =< x <= 5.
