Answer:

=10x2−8

Step-by-step explanation:

4(x2−5)+2(3x2+6)

Distribute:

=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)

=4x2+−20+6x2+12

Combine Like Terms:

=4x2+−20+6x2+12

=(4x2+6x2)+(−20+12)

=10x2+−8

Diana has an end table in the shape of a right triangle. The triangular tabletop is twice as high as it is wide at the base. If

n200080 [17]

Answer:

The width of the base is 2.828 feet

Explanation:

Given the area of the table top is 4 square feet

The triangular table top is twice as high as it is wide at the base

Therefore, we can say that height = base

Area of a right angled triangle is calculated by, Area = ½ * base * height

In this case, height = base

Therefore, area = $\frac{1}{2}\times (base)^2$

Substituting the values,

4 = $\frac{1}{2}\times (base)^2$

$(base)^2$ = 8

Base = 2√2 = 2 * 1.414 = 2.828 feet

Therefore, the width of the base is 2.828 feet

Instructions: Given the vertex, fill in the vertex form of the quadratic function..

miskamm [114]

Answer:

$\implies y=(x-2)^2-6$

Step-by-step explanation:

Vertex form of a quadratic equation:

$y=a(x-h)^2+k$

where:

(h, k) is the vertex
a is some constant

Given vertex: (2, -6)

⇒ h = 2 and k = -6

Substitute the values of h and k into the formula:

$\implies y=a(x-2)^2+(-6)$

$\implies y=a(x-2)^2-6$

As we have not been given a value for the constant $a$ , assume this is 1.

Therefore, the vertex form of the quadratic function with vertex (2, -6) is:

$y=(x-2)^2-6$
