(3x + 5)(4x^2 + 8x + 40)

Answer:

Step-by-step explanation:

The total number of marbles is 6 + 8 + 4 = 18]

If the first marble drawn is yellow, that happens with a probability of 8/18

So the important thing to note is that now there are 17 marbles,

Now a red marble is drawn. We didn't replace the yellow.

There are 6 red marbles.

So the chances of getting a red marble is 6/17

Answer. P(Y then R) = 8/18 * 6/17 = 48/306

48 / 306 reduces down to 8/51  = 0.156

Answer:

2064

Step-by-step explanation:

18 + 21 + 24 + ...

This is an arithmetic series with first term 18 and common difference 3.

The nth term is

18 + 3(n - 1)

The 32nd term is the number of seats in the 32nd row:

18 + 3(32 - 1) = 18 + 3(31) = 18 + 93 = 111

The sum of the series is:

n/2(a + L) = (32/2)(18 + 111) = 2064

Answer: as a square and four semicircles

Step-by-step explanation:

The composite shape area can be found by first decomposing the figure as: a square and four semicircles.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

to Find the Area of a Composite Figure:

To find the area of a composite figure, the first thing to do is to identify the individual shapes that make up the figure, then find the area of each shape before adding all the areas together.

For a composite figure that is comprised of a square and 4 semicircles, the composite figure would be decomposed into: a square and four semicircles.

Hence, The composite shape area can be found by first decomposing the figure as: a square and four semicircles.

The function which is the vertex form of the equation whose first three steps shown in writing is  f(x)=5(x +4)²- 80.

Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.

The standard equation of the vertex form of parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

Here, (h, k) is the vertex point.

The first three steps in writing the function in vertex form are shown.

[tex]f(x) = 40x +5x^2[/tex]

Write the function in standard form.

[tex]f(x) = 5x^2+ 40x[/tex]

Factor out of the first two terms by taking out the common number 5 from the equation,

[tex]f(x) = 5(x^2 +8x)[/tex]

Form a perfect square trinomial with (8/2)² = 16,

[tex]f(x) = 5(x^2 +8x+ 16) - 5(16)\\f(x) = 5(x+4)^2 - 80[/tex]

n = 7

Step-by-step explanation:

n+ 4 = 11       subtract 4 from both sides of the equation

n + 4 -4 = 11-4

n = 7

Hey there!

n + 4 = 11

SUBTRACT 4 to BOTH SIDES

n + 4 - 4 = 11 - 4

CANCEL out: 4 - 4 because it give you 0

Answer:

If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased,

the f(x) will be increased by 0.5. The graph function should be: 

f(x)= x/2A positive difference means that the value should be always positive.
To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:

f(x+3) - f(x)f(3)- f(0)=1.5 - 0= 1.5The answer would be: 1.5

[tex]\rightarrow \sf y = 2x+1[/tex]

Answer:

[tex]y = 2x- 1[/tex]

Step-by-step explanation:

To determine which equation passes through the points (3, 7) and (-1, -1), we need to determine the slope of the equation. Then, we shall use point slope form to determine the equation of the line.

Determining the slope of the line:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run} } =\dfrac{\text{y}_{2} - \text{y}_{1} }{\text{x}_{2} - \text{x}_{1} }[/tex]

Substituting the points in the slope formula:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

Simplifying the slope:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

[tex]\text{Slope} =\dfrac{-8}{-4 } = 2[/tex]

Determining the equation of the line:

We shall use point slope form to determine the equation of the line.

[tex]\text{Point slope form:} \ y - y_{1} = m(x- x_{1} )[/tex]

Substitute the slope and the coordinates of any two points stated above.

[tex]y -7= 2(x- 3 ) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Using the point (3,7)}][/tex]

Simplify the equation and organize it to slope intercept form:

[tex]y -7= 2x- 6[/tex]

[tex]y = 2x- 6 + 7[/tex]

[tex]y = 2x+ 1[/tex]

The quadratic regression equation of company X sales would have a degree of 2

To determine the quadratic regression equation, we make use of a graphing calculator

From the graphing calculator,we have the following calculation summary

A quadratic regression equation is represented as:

y = ax^2 + bx + c

So, we have:

y = -507.61x^2 +23372.94x -170697.85

Hence, the quadratic regression equation is y = -507.61x^2 +23372.94x -170697.85

This means that:

x = 22.75

So, we have:

y = -507.61 * 22.75^2 + 23372.94 * 22.75 -170697.85

Evaluate

y = 98316.63

Hence, the profit for selling at $22.75 is $98316.63

We will see that the length of the browser window is 4.9 inches, and the screen is a square of sidelength 10.2 in

We know that the area of the browser window is 24 in^2, we will assume that the window is a perfect square, then the area is equal to the square of the length x, we have:

x^2 = 24 in^2

x = √(24 in^2) = 4.9 in

We know that the browser covers 3/13 of the screen, so the area of the screen is 13/3 times the area of the browser:

A = (13/3)*24 in^2 = 104 in^2

Again, if the screen is square of sidelength s, we have:
