A book sold 33,400 coples in its first month of release. Suppose this represents 7.6% of the number of coples sold to date. How many coples have been sold todate?Round your answer to the nearest whole number.

Answers

The number sold in the first month is given as 33,400.

This number is 7.6 percent of the total copies sold till date. This means x copies have been sold till date, and x copies represents 100 percent.

Therefore, you would have the following proportion;

[tex]\begin{gathered} \frac{33400}{x}=\frac{7.6}{100} \\ \text{Cross multiply and you'll have;} \\ \frac{33400\times100}{7.6}=x \\ 439473.684210\ldots=x \\ x\approx439474\text{ (rounded to the nearest whole number)} \end{gathered}[/tex]

The number of copies sold till date is 439,474 (rounded to the nearest whole number)

Answers

Part A: Use the graph to identify the zeros of the polynomial.

As it is said in the introduction the graph crosses 3 times the x -axis and touched it at (2,0).

Values of x for which the function is zero can be identified by knowing the x-coordinate of these points:

[tex]x=-4[/tex][tex]x=2[/tex]

And the following two that are approximate values taken from the graph:

[tex]x\approx-1.6[/tex]

[tex]x\approx3.6[/tex]

Part B: Use the behaivor of the graph to explain whether the dregree of the polinomial is even or odd.

The graph the graph corresponds to an odd function because has no symmetry abopur the y-axis and when the value of x get smaller the values of y also. To the left from a certain point lower values are always obtained and to the right from a certain point higher values are always obtained.

Jessica bought a house at auction for $82,500. The auction company charges a 15% premium on the final bid. how much will jessica pay for the house

Answers

First, we need to find the 15% of $82,500 as:

[tex]82,500\cdot15\text{ \% = 82,500 }\cdot\frac{15}{100}=12,375[/tex]

It means that Jessica will pay $82,500 for the house plus $12,375 to the auction company. So, in total, Jesica will pay for the house:

$82,500 + $12,375 = $94,875

• A horizontal plane, that cuts through the pyramid, parallel to the base:, ,square

,

• A vertical plane that cuts through the base and two opposite lateral faces:, ,trapezoid

EXPLANATION

• A vertical plane that cuts through the top vertex, perpendicular to the base,: if we draw a rectangle perpendicular to the base that passes through the vertex,

Hence, the cross-sectional shape is a triangle.

• A horizontal plane, that cuts through the pyramid, parallel to the base:, if it is a plane parallel to the base, then it should have the same shape as the base,

Hence, the cross-sectional shape is a square.

• A vertical plane that cuts through the base and two opposite lateral faces:, again, we can draw this plane. The cross-sectional shape will have one pair of parallel sides and one pair of non-parallel sides,

Hence, the cross-sectional shape is a trapezoid.

Answer: (-2,3)

Step-by-step explanation:

2x-5y=-19    (1)

-3x+y=9       (2)

2x-5y=-19     (3)

y=3x+9          (4)

2x-5(3x+9)=-19

2x-15x-45=-19

-13x=-19+45

-13x=26

Divide both parts of the equation by -13:

x=-2

Substitute the value of x=-2 into equation (4):

y=3(-2)+9

y=-6+9

F(x)=2|x-1| Graph using transformations and describe the transformations of the parent function y =x^2.

Answers

[Please see that in the question should be a mistake regarding the parent function. It should be written y = |x| instead of y = x².]

To answer this question, we need to know that the below function is a transformation of the parent function, f(x) = |x|:

[tex]f(x)=2|x-1|[/tex]Describing the transformations

To end up with the above function from the parent function, we need to follow the next steps:

1. Translate the function, y = |x| one unit to right. We can do this by subtracting one unit to the parent function as follows:

[tex]f(x)=|x-1|[/tex]

We can see this graphically as follows:

The blue function is the first transformation of the parent function, f(x) = |x|.

2. The function has been dilated by a factor of 2 from the x-axis. That is, the function has been dilated by a factor of 2 vertically. Then, we have:

[tex]f(x)=2|x-1|[/tex]

And now, we can see the transformation graphically as follows:

Therefore, the blue line is the graph representation of the function:

[tex]f(x)=2|x-1|[/tex]

All questions relate to the equation y=9 x^2-36 x+37Got it.1. Which way does the parabola open? Your answerYour answerYour answer2. What is the minimum value of y?Your answer3. What is the maximum value of y?Your answer5. What is the axis of symmetry?7. What is the y-intercept?Your answer8. Rewrite the equation in vertex form.

Answers

Given the parabola:

[tex]y=9x^2-36x+37[/tex]

Part 1

To determine the way the parabola opens, we consider the coefficient of x².

• If the coefficient is positive, it opens downwards.

,

• If the coefficient is negative, it opens upwards.

In this case, the coefficient of x²=9 (Positive).

The parabola opens downwards.

Part 2

The minimum value of the parabola occurs at the line of symmetry.

First, we find the equation of the line of symmetry.

[tex]\begin{gathered} x=-\frac{b}{2a};a=9,b=-36,c=37 \\ \therefore x=-\frac{(-36)}{2\times9} \\ x=2 \end{gathered}[/tex]

Find the value of y when x=2.

[tex]\begin{gathered} y=9x^2-36x+37 \\ y=9(2)^2-36(2)+37 \\ =36-72+37 \\ Min\text{imum value of y=1} \end{gathered}[/tex]

Part 3

Since the graph has a minimum value, the maximum value of y will be ∞.

Part 5

As obtained in part 2 above, the axis of symmetry is:

[tex]x=2[/tex]

Part 6

The vertex is the coordinate of the minimum point.

At the minimum point, when x=2, y=1.

Therefore, the vertex is (2,1).

Part 7

The y-intercept is the value of y when x=0.

[tex]\begin{gathered} y=9x^2-36x+37 \\ y=9(0)^2-36(0)+37 \\ y=37 \end{gathered}[/tex]

The y-intercept is 37.

Part 8

We rewrite the equation in Vertex form below:

[tex]\begin{gathered} y=9x^2-36x+37 \\ y-37=9x^2-36x \\ y-37+36=9(x^2-4x+4) \\ y-1=9(x-2)^2 \\ y=9(x-2)^2+1 \end{gathered}[/tex]

Answer: 0.021

First, we will find the total number of results by adding up all the subject results in the table:

Now, we know there are 435 total results. We are asked to find the probability that the subject has the disease given that the test result is negative.

Looking at the table, we can see that the number of subjects that has the disease despite having negative results is 9. We will then divide these results by the total number of subject results to find the probability being asked:

[tex]P=\frac{9}{435}=0.020689\approx0.021[/tex]

With this, we know that the probability of the subject having the disease given the results is negative is 0.021.

Find all the roots of y = x4 + 7x3 + 25x2 - 11x – 150

Answers

Given the equation :

[tex]y=x^4+7x^3+25x^2-11x-150[/tex]

to find the roots of he function , y = 0

so,

[tex]x^4+7x^3+25x^2-11x-150=0[/tex]

the factors of 150 are;

1 x 150 , 2 x 75 , 3 x 50 , 5 x 30 ,

We will check which number give y = 0

so, when x = 1 , y = -128

When x = -1 , y = -120

when x = 2 , y = 0

So, x = 2 is one of the roots

so ( x - 2 ) is one of the factors of the given equation :

Make a long division to find the other roots:

so,

[tex]\frac{x^4+7x^3+25x^2-11x-150}{x-2}=x^3+9x^2+43x+75[/tex]

See the following image:

Now , we will repeat the steps for the result

the factors of 75

1 x 75 , 3 x 25 , 5 x 5

We will check which number give y = 0

when x = 1 , y = 128

when x = -1 , y = 40

When x = 3 , y = 312

when x = -3 , y = 0

so, x = -3 is another root

So, ( x + 3 ) is one of the factors

so, make a long division again to find the other roots:

[tex]\frac{x^3+9x^2+43x+75}{x+3}=x^2+6x+25[/tex]

See the following image :

Now the last function :

Second statement:

what is the size of rectungle 2x2x2

Answers

Perimeter: 8 u

Area: 4 u^2

Volume: 8 u^3

Explanation:

u = unit (cm / m etc...)

side = 2 u

Formula for a rectangle:

Perimiter : 2*(side + side)

=> 2 * ( 2 + 2) = 8 u

Area: side * side

=> 2 * 2 = 4 u^2

Volume: Area * Height

=> 2 * 4 u^2 = 8 u^2

Which of the following sets number could not represent the three sides of a right triangle

Answers

Given 4 sets of three sides of a triangle

We will find Which of the following sets of numbers could not represent the three sides of a right triangle

First, for any right triangle, the sum of the square of the legs is equal to the square of the hypotenuse

The hypotenuse is the longest side of the triangle

We will check the options:

a) { 11, 60, 61}

[tex]11^2+60^2=121+3600=3721=61^2[/tex]

So, option a represent a right triangle

b) {46, 60, 75 }

[tex]46^2+60^2=2116+3600=5716\ne75^2[/tex]

So, option (b) does not represent a right triangle

No need to check the other options

So, the answer will be {46, 60, 75}
