1.- What type of parabola is this?

xz_007 [3.2K]

Answer:

Part 1

Sideways or "horizontal" parabola with a horizontal axis of symmetry.

Part 2

The vertex is the turning point: (-3, 1)

Part 3

Vertex form of a horizontal parabola:

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

where:

(h, k) is the vertex
a is some constant
If a > 0 the parabola opens to the right.
If a < 0 the parabola opens to the left.

Point on the curve: (-1, 2)

Substituting the vertex and the found point into the formula and solving for a:

$\implies -1=a(2-1)^2-3$

$\implies -1=a-3$

$\implies a=2$

Part 4

Equation for the given parabola in vertex form:

$x=2(y-1)^2-3$

Equation in standard form:

$x=2y^2-4y-1$

30 is 120% of what number? show ur work

Yanka [14]

Answer:

30 is 120% of 25

Step-by-step explanation:

30 = 120% of y

$\frac{120}{100}$ × y = 30

After multiplying both sides by 100 and dividing both sides by 120, we have

y = 30 × $\frac{100}{120}$

y = 25

On a coordinate plane, a parabola opens down with solid circles along the parabola at (negative 3, negative 5), (negative 2, 0),

Svetradugi [14.3K]

The true statement regarding the intervals where the function is increasing and decreasing is option A: The function is increasing from (–∞, 0).

<h3>What is a function?</h3>

A function is defined as a relation between the set of inputs having exactly one output each.

On a coordinate plane, a parabola opens down with solid circles along the parabola at (-3, -5), (-2, 0), (-1, 3), (0, 4), (1, 3), (2, 0), (3, -5).

The domain is all real numbers.

The range is all real numbers.

If for an interval I, when x decreases meanwhile staying in interval I, the function's output increases (or can stay same), then we say that the function is increasing in the interval.

The true statement regarding the intervals where the function is increasing and decreasing is option A: The function is increasing from (–∞, 0).

12x+6x^2(3x-2)-8x^2-7x

Colt1911 [192]

Answer:

x⋅(2x+1)⋅(2x+3)⋅(3x−2)

Step-by-step explanation:

Equation at the end of step 1

(((12•(x4))+(16•(x3)))-7x2)-6x

STEP

Equation at the end of step

(((12 • (x4)) + 24x3) - 7x2) - 6x

STEP

Equation at the end of step

(((22•3x4) + 24x3) - 7x2) - 6x

STEP

Pulling out like terms

5.1 Pull out like factors :

12x4 + 16x3 - 7x2 - 6x =

x • (12x3 + 16x2 - 7x - 6)

Checking for a perfect cube :

5.2 12x3 + 16x2 - 7x - 6 is not a perfect cube
