Which statements correctly describe the graph of the function f(x) = x3 – 2x2 - 19x + 20? Select three options.
As the x-values increase, the y-values always increase.
As x approaches negative infinity, y approaches negative infinity.
O The domain of the function is all real numbers.
The range of the function is y > 20.
The graph has a positive y-intercept.

Answer:

0.05(2x +4) +0.25x =2.65

Step-by-step explanation:

The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.

Answer:

0.05(2x +4) +0.25x =2.65 or b

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

x=26/7

y=115/7

Step-by-step explanation:

7x+10=36>>subtract 10 from 10 and 36 you get 7x=26>>>divide both sides by 7>>>>x=26/7

To find find y you substitute the x for 26/7>>2(26/7)+9=115/7

Answer:

x = 4 & 2

Step-by-step explanation:

-2x²+12x-16 = 0

-2(x²-6x+8) = 0 // Factor what's in the parentheses

-2(x-4)(x-2) = 0

-2(x-4) = (-2x+8)

(-2x+8) = 0 // Subtract 8 on both sides

-2x = -8 // Divide both sides by -2

x = 4

x-2 = 0 // Add 2 on both sides

x = 2

Answer:

x=72

Step-by-step explanation:

180-36=144 (180 degrees in a triangle)

144/2=72

In the isosceles triangle having one angle is 36° and rest two equal angles are x then the value of x is, 72°

Any triangle with any two sides that have the same length is known as an isosceles triangle. An isosceles triangle has two angles that are equal in size and opposed to its equal sides.

In an isosceles triangle, the two equal angles are congruent, so we can call one of them "x". The sum of the angles in a triangle is 180°, so we can set up an equation to solve for x:

x + x + 36° = 180°

Simplifying the equation:

2x + 36° = 180°

Subtracting 36 from both sides:

2x = 144°

Dividing both sides by 2:

x = 72°

So, the value of x is 72°.

Answer:

54

Step-by-step explanation:

What I would do is multiply 12x4 first to get 48, then after I'd multiply 12x1/2 to get 6 then I'd add them together to get 54.

Answer and Step-by-step explanation:

We are given a triangle and are asked to solve for the value of y.

We know that the angles in a triangle add up to 180 degrees. So let's add all of the angles together and equal it to 180.

2y + y + 10 + 50 = 180

Combine like terms.

3y + 60 = 180

Now subtract each side by 60.

3y = 120

Finally, divide each side by 3.

y = 40

We get the value of y to be 40.

Answer:

Option C

{ - ⁵/₃ , ³/₂ }

Step-by-step explanation:

6x² + x - 15 = 0

6x² + 10x - 9x - 15 = 0

2x(3x + 5) - 3(3x + 5) = 0

(2x - 3) (3x + 5) = 0

2x - 3 = 0 or 3x + 5 = 0

x = ³/₂ or x = - ⁵/₃

Thus, The answer is { - ⁵/₃ , ³/₂ }

x^4-3x^3+x^2-4

mrk me brainliest plz

Step-by-step explanation:

Given the following functions

R(x) = 2x^4 – 3x^3 + 2x – 1 and

C(x) = x^4 – x^2 + 2x + 3

We are to find the profit function P(x)

P(x) = R(x) - C(x)

P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)

P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3

Collect the like terms

P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3

P(x) = x^4-3x^3+x^2+0-4

P(x) = x^4-3x^3+x^2-4

Hence the required profit function P(x) is x^4-3x^3+x^2-4

Answer:

Below.

Step-by-step explanation:

The parabola will open to the right and will be symmetrical about y = 3.

The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).

The p value is the distance between the vertex and the focus - here it is 1 - -3

= 4.

Answer:

The parabola has a vertex at (-3, -6), has a p-value of 4 and it opens right.

Answer:

64π^2  cubic inches

Step-by-step explanation:

The question is not complete, the shapes are not given

Diameter of base= 16π

Radius of base= 8π

Height of cylinder = 8 inches

Let us find the volume of the cylinder

V= πr^2h

V= π* (8π)* 8

V= 64π^2  cubic inches

Hence the volume of the cylinder is 64π^2  cubic inches

Answer:

Step-by-step explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines.   so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer:

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.

Answer:

m∠b=m∠c=61°

Step-by-step explanation:

The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.

[tex]b+119=180[/tex]

[tex]b=61[/tex]

Since b and c are equal, c=61 too.
