What is the y-value of the vertex of the function f(x)=−(x−3)(x+11)? −8 −4 33 49
alisha [4.7K]

Answer:

y - value of the vertex is 49.

Step-by-step explanation:

Given function is f(x) = -(x - 3)(x + 11)

f(x) = -(x² - 3x + 11x - 33)

     = -(x² + 8x - 33)

     = -(x² + 8x + 16 - 49)

     = -[(x + 4)² - 49]

     = -(x + 4)² + 49

Comparing this equation with the vertex form of a quadratic function,

f(x) = -(x - h)² + k

Where (h, k) is the vertex of the function.

Vertex of the parabola is (-4, 49)

Therefore, y-value of the vertex is 49.

The rectangular prism is made of 8 cubes and has and edge length of 1/2 in, what is the volume
sashaice [31]
Hello!

To find the volume of the prism you first have to find the volume of a cube

To do this you use the equation

V =  a^{3}

V is volume
a is side length

Put in the values you know

V =  \frac{1}{2}^{3}

Solve

V = 0.125

Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism

0.125 * 8 = 1

The answer is 1 cubic inch

Hope this helps!
