Answer:
the vertex is at (2, 8) and the axis of symmetry is x = 2
Step-by-step explanation:
In h(x)=−2x2+8x please use the symbol " ^ " to indicate exponentiation:
h(x)=−2x^2+8x
This is a quadratic equation with coefficients a = -2, b = 8 and c = 0.
The axis of symmetry equation is x = -b/ (2a).
-8
Here, with a = -2 and b = 8, the axis of symmetry is x = --------- = 2
2(-2)
To find the y-coordinate of the vertex, substitute 2 for x in h(x)=−2x^2+8x, obtaining
h(2) = -2(2)^2 + 8(2) = -2(4) + 16 = 8
In summary, the vertex is at (2, 8) and the axis of symmetry is x = 2.
The correct answer is 1/3f +36 = 85. You can figure this out by reading this "<span>The number of State Parks in California is <u>36 more than one third the number of State Parks in Florida</u>" and writing it as an equation.
85 = <u>1/3f + 36</u></span>
Answer:
the surface area of the cube is 150 inches squared
Step-by-step explanation:
The computation of the surface area of the cube is shown below:
As we know that
The surface area of the cube is
= 6s^2
= 6(5)^2
= 150 inches squared
hence, the surface area of the cube is 150 inches squared
Answer:
-23
Step-by-step explanation:
A quadratic equation is given to us and we are interested in finding the discriminant of the quadratic equation . As we know that ,
If the quadratic equation is in Standard form ,
The discriminant is ,
The given quadratic equation is ,
On comparing it with the Standard form , we have ,
So that ,
Also note that if D < 0 , then the roots are complex conjugates .
<h3>Hence the discriminant is (-23).</h3>
