5? *
A quadratic equation is in the form of ax²+bx+c. The graph of the equation y = -2x² + 4x -5 will not intersect the x-axis at any point.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The given equation is a quadratic equaion, therefore, to know if the equation will intersect with the x-axis we need to find the roots of the equation.
Since the value of the discriminant is negative for this equation, the roots of the equation will be imaginary. Plotting the graph, we will observe that the graph will not intersect the x-axis at any point.
Hence, the graph of the equation y = -2x² + 4x -5 will not intersect the x-axis at any point.

Step-by-step explanation:
=> x² - 36
=> x² - 6²

An above ground pool is shaped like a cylinder. It is 5.5 feet tall and has a diameter of 20 feet. If the pool is filled to 5 feet, what is the volume of the water? If the pool is filled to the top, what is the volume of the water?
First, we must know the formula for solving the volume of a cylinder, which is [tex]V = \pi r^2 h[/tex]. Since the water is only being filled to 5 feet, we do not care about the 0.5 feet of the height.
Using the formula, we need to plug-in the numbers for the radius (20 divided by 2 is 10) and height. Doing this, the equation should now look like this: [tex]V = 3.14 * 10^2 * 5[/tex]. When solving, the volume of the water is 1570 feet cubed.
Answer:
1570.796 feet cubed
Step-by-step explanation:
First you find the surface area of the base of the cylinder which should look like this:
(10^2)(π)
Next you multiply that by the height (5 feet) because 3d shapes are bases stacked on each other which should look like this:
314.1592654(5)
After that arithmetic you will get 1570.796 or 1570.8 rounded as your answer!

Hey ! Buddy .
As the question is in Spanish . So we have provided your answer in English as well as in Spanish language .
( ¡Oye! Amigo, la pregunta es en español. Así que hemos proporcionado su respuesta tanto en inglés como en español. )
Answer:
Value of x is 36 (El valor de x es 36)Step-by-step explanation:
In this question we have given with an equation that is -6x + 71 = -4x - 1 . And have to find the value of x .
( En esta pregunta hemos dado con una ecuación que es -6x + 71 = -4x - 1 . y hay que encontrar el valor de x )
Solution : -
( Soluciones : - )
[tex] \quad : \implies - 6x + 71 = - 4 - 1[/tex]
Step 1 : Subtracting 71 on both sides :
( Paso 1 : Restando 71 en ambos lados: )
[tex]\quad : \implies - 6x + \cancel{71} - \cancel{71} = - 4x - 1 - 71[/tex]
On calculating further, We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies - 6x = - 4x - 72[/tex]
Step 2 : Adding 4x on both sides :
( Paso 2 : Sumando 4x en ambos lados: )
[tex]\quad : \implies - 6x + 4x = - \cancel{4x} + \cancel{4x } - 72[/tex]
On calculating further, We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies \cancel{-} 2x = \cancel{-}72[/tex]
Step 3 : Dividing by 2 on both sides :
( Paso 3 : Dividiendo por 2 en ambos lados: )
[tex]\quad : \implies \frac{ \cancel{2}x}{ \cancel{2} } = \cancel{\frac{72}{2} }[/tex]
On calculating further , We get :
( Al calcular más, obtenemos : )
[tex]\quad : \implies \: \green{ \boxed{ \frak{x = 36}}}[/tex]
Therefore , value of x is 36 . ( Por lo tanto , el valor de x es 36 . )Verifying : -
( Comprobación :- )
We are verifying our answer by substituting value of x in given equation. So ,
( Estamos verificando nuestra respuesta al sustituir el valor de x en la ecuacióndada. Asi que, )
-6x + 71 = -4x - 1 -6 ( 36 ) + 71 = -4 ( 36 ) - 1-216 + 71 = -144 - 1-145 = -145L.H.S = R.H.S (Lado izquierdo = Lado derecho )Hence, Verified. ( Por lo tanto, Verificado. )Therefore, our solution is correct.

Consider two events, P and Q. The probability of event P occurring is 16. The probability of event Q occurring is 23. Which statement is true?
The event "P and Q" is a compound event in the probability, and the true statement about the probability is P(P and Q) = 1/9
How to determine the true statement?The probabilities are given as:
P(P) = 1/6
P(Q) = 2/3
The probability of the event P and Q is calculated using:
P(P and Q) = P(P) * P(Q)
This gives
P(P and Q) = 1/6 * 2/3
Evaluate the product
P(P and Q) = 1/9
Hence, the true statement about the probability is P(P and Q) = 1/9

1. Given: LMN ~ QPR, find RQ.
Answer:
C. 27
Step-by-step explanation:
If those two triangles are similar then look at how much one side is being increased to the other triangle. ML is similar to PQ and it increases by 1.5 to get there.
So find the side similar to RQ which is LN
1.5(x+7)=2x+5
1.5x+10.5=2x+5
5.5=0.5x
x=11
Then plug in 11 for x to find RQ which will be 27

Y=-x^2+8x+11
Y=5x-7
Answer:
ummmm..... let's see..
Step-by-step explanation:
using "Almighty formula"
{Y = –x +/– √b^2 – 4ac / 2a}
so we name all the values behind the coefficients which are; –1^2, 8 and 11
so let's assign a,b,c to these values:
a =–1, b =8, c = 11
all you just do now is to add these values to the formula
you should be having Y =1 +/– √8^2 – 4×–1×11
———————————
2×–1
Y =1 +108
———— or Y = 1–108
–2 –––––
–2
now add and divide to get Y.

Answer:
(- [tex]\frac{1}{5}[/tex] , 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
5x - 2(0) + 1 = 0
5x - 0 + 1 = 0
5x + 1 = 0 ( subtract 1 from both sides )
5x = - 1 ( divide both sides by 5 )
x = - [tex]\frac{1}{5}[/tex]
the line crosses the x- axis at (- [tex]\frac{1}{5}[/tex], 0 ) or ( - 0.2, 0 )
Answer:
(-1/5, 0).
Step-by-step explanation:
Where the line crosses the axis the value of y = 0.
5x - 2y + 1 = 0
Let y = 0, then:
5x - 2(0) + 1 = 0
5x + 1 = 0
5x = -1
x = -1/5.
So the point is (-1/5, 0).
