Hello there!
the answer would be A 

Hope this helps! :)
~Zain

Answer:

Option: C is the correct answer.

[tex]f(x)=x^3+x^2-9x-9[/tex]

Step-by-step explanation:

Clearly from the graph we could see that:

3 and -3 are zeros of the function f(x).

since the graph crosses these two points on the x-axis.

i.e. when x=3 or -3 ⇒ f(x)=0

Now when we put x=3 in each of the equation we see that:

A)

[tex]f(x)=x^3+2x^2-4x-8[/tex]

when x=3

[tex]f(x)=3^3+2\times 3^2-4\times 3-8\\\\f(x)=27+18-12-8\\\\f(x)=25\neq0[/tex]

Hence, option A is incorrect.

B)

[tex]f(x)=x^3+4x^2-x-4[/tex]

when x=3

[tex]f(x)=27+36-3-4\\\\f(x)=56\neq0[/tex]

Hence, option B is incorrect.

D)

[tex]f(x)=x^3+3x^2-3x-9[/tex]

when x=3

[tex]f(x)=27+27-9-9\\\\f(x)=36\neq0[/tex]

Hence, option D is incorrect.

Hence all the three options are discarded.

Hence, option C is the correct answer.

The function best represents the graph is:

HELP! A scale model of an ancient Egyptian pyramid is 29 centimeters high, with a base length of 46 centimeters.

The height of the real pyramid is 145 meters. What is the base length of the real pyramid?

Enter your answer, in simplest form, in the box

Answers

Scale models are used to draw large scale models on paper using smaller dimensions. The dimensions on paper should be in the proper ratio as in the actual model.
In this question, the height of the real pyramid is 145 meters.
However in the drawing, 145 meters have been represented in 29 cm.
lets make both measurements in the same unit,
145 m ---> 14 500 cm
29 cm
29 cm on the scale diagram represents 14 500 cm on the actual model
therefore 1 cm  represents - 14 500/29 = 500 cm on the actual model 
Therefore ratio is 1:500

base length of the scale pyramid is - 46 cm
1 cm on model represents 500 cm 
Therefore 46 cm represents ---> 46 x 500 cm
 the actual base length = 23 000 cm
                                     = 230 m

A building lot in a city is shaped as a 30°-60°-90° triangle, like the figure shown.

The side opposite the 30° angle measures 41 feet.

A) find the length of the side of the lot opposite the 60° angle.(show how I know).

B) find the length of the hypotenuse of the triangular lot.(show how I know)

Answers

check the picture below.
A) You can find the length of the side of the lot opposite the 60° angle  (which we will call "x") as below:

 Tan(α)=Opposite/Adjacent

 α=60°
 Opposite=41 feet
 Adjacent=x

 When you substitute these values into Tan(α)=Opposite/Adjacent, you obtain:

 Tan(60°)=x/41
 (41)Tan(60°)=x
 x=41√3
 x=71.01 feet

 B) Now, you can find the length of the hypotenuse:

 Cos(α)=Adjacent/Hypotenuse

 α=60°
 Adjacent=41 feet
 Hypotenuse=y

 When you substitute these values into Cos(α)=Adjacent/Hypotenuse, you obtain:

 Cos(60°)=41/y
 yCos(60°)=41
 y=41/Cos(60°)
 y=82 feet

Given is a Right triangle PQR with angle Q = 90 degrees.

Given are sides PQ = 8 cm, QR = 15 cm, PR = 17 cm.

Side PR is the hypotenuse.

We can use formula for "sin" given as follows :-

[tex] sin(\theta)=\frac{Opposite}{Hypotenuse} [/tex]

For angle R, opposite side would be PQ.

[tex] sin(R)=\frac{PQ}{PR} \\\\
sin(R)=\frac{8}{17} \\\\
sin(R)=0.470588235 \\\\
R=sin^{-1}(0.470588235) \\\\
R = 28.07248694 \;\;degrees \approx 28.07 \;degrees [/tex]

For angle P, opposite side would be QR.

[tex] sin(P)=\frac{QR}{PR} \\\\
sin(P)=\frac{15}{17} \\\\
sin(P)=0.882352941 \\\\
P=sin^{-1}(0.882352941) \\\\
P = 61.92751306 \;\;degrees \approx 61.93 \;degrees [/tex]

Hence, R = 28.07 degrees and P = 61.93 degrees.

To solve the problem we must know about Trigonometric functions.

Trigonometric functions

[tex]\rm {Cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\rm {tan\theta=\dfrac{Perpendicular}{Base}[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

The value of the ∠R is 28.0724°.The value of the ∠P is 61.9275°.

Given to usPR = 17 cmQR = 15 cmPQ = 8 cm

1. For ∠R

For ∠R, the opposite side will be PR, therefore, PR will be the Perpendicular,

Substituting the values in the formula of Sine,

[tex]\rm {Sin (\angle R)=\dfrac{PQ}{PR}\\\\ [/tex]

The measure of variation for a numerical data set describes how the values of a number vary with the single number. This measurement shows the difference in the properties of a certain number to the rest of the numbers in the numerical data set.

Final answer:

The term that describes how values of a numerical data set vary with a single number is 'variation'. It quantifies the spread of data values, helping to add context and meaning to averages in a data set.

Explanation:

A measure of variation for a numerical data set describes how its values vary with a single number. Variation is a statistical concept that is used to quantify the spread or dispersion of a set of data values. A low variation indicates that the data points tend to be close to the mean (or expected value), while a high variation indicates that the data points are spread out over a wider range.

For example, if we have a data set of test scores, the variation can help us understand how close or far the scores are from the average test score. This provides more context and meaning to the overall average.

Jordan is a manager of a car dealership. He has two professional car washers, Matthew and Arianna, to clean the entire lot of cars. Matthew can wash all the cars in 14 hours. Arianna can wash all the cars in 11 hours. Jordan wants to know how long it will take them to wash all the cars in the lot if they work together.

Write an equation and solve for the time it will take Matthew and Arianna to wash all the cars together. Explain each step.

Answers

Assuming that X represents the number of hours worked and f(x) the number of cars washed, the equation would be f(x)=11x+14x.

The 11x represents the number of cars washed by Arianna in x number of hours and the 14x represents the number of cars washed by Matthew in x number of hours. You add the two because they are each washing their own car at their own pace but working on one lot. 

Answer:

They will take 6.16 hrs or 6 hrs, 9 minutes and 36 seconds.

Step-by-step explanation:

Consider the provided information.

Let x is the number of cars in a lot.

Matthew can wash all the cars in 14 hours. That means in 1 hr he can wash x/14 cars.

Arianna can wash all the cars in 11 hours. That means in 1 hr Aranna can wash x/11 cars.

Together there rate will be:

[tex]\frac{x}{14}+\frac{x}{11}=\frac{x}{y}[/tex]

Here y represent the time taken by them if they work together.

Divide both sides by x, we get

[tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]

Thus, the required equation is: [tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]

Now solve for time, Here time is represents by y.

[tex]\frac{1}{14}+\frac{1}{11}=\frac{1}{y}[/tex]

[tex]\frac{11+14}{154}=\frac{1}{y}[/tex]

[tex]\frac{25}{154}=\frac{1}{y}[/tex]

[tex]y=\frac{154}{25}[/tex]

[tex]y=6.16[/tex]

Hence, they will take 6.16 hrs or 6 hrs, 9 minutes and 36 seconds.

Answers

1. (18/5,0)
First let us find the equation of AB. It should be in the form of y=mx + b
From the given coordinates, you can get m, x, and b.

m= y2-y1 divided by x2 - x1
m=(6-2)/(7- -3)= 4/10 or 2/5
m= 2/5

b is your y intercept
To get it, use 1 coordinate either from point A or B.
Let point A be the coordinates
y=mx + b
-3= 2/5(2) + b
b= - 3- 4/5
b= 16/5


Now we will find the equation of CD,
y=mx + b
y= (-5/2)x + b
Then get the coordinates of point C through midpoint equation,
(x1+x2) /2, (y1+y2) /2
(-3+7)/2, (2+6)/2
=C(2,4)
We will use this coordinates to find b,
y=mx+b
4=(-5/2)2+b
4+5=b
b=9
If we are finding the x intercept, y value should be 0.
0=(-5/2)x+9
0-9(2)/-5=x
x= 18/5
The x intercept of CD is (18/5,0)

Find the lateral area of a right circular cone whose radius is 6 feet and height is 8 feet.

Answers

Final answer:

The lateral area of a right circular cone with a radius of 6 feet and height of 8 feet is 60π square feet. We calculate this by first finding the slant height using the Pythagorean Theorem and then substituting the radius and slant height into the formula for the lateral area of a cone.

Explanation:

The lateral area of a cone can be calculated using the formula πrl, where r is the radius and l is the slant height. However, in this question, we're not provided the slant height, but the height. Therefore, we first need to find the slant height using the Pythagorean theorem, since a right circular cone forms a right triangle with the radius and the height. Using Pythagorean theorem, the slant height (l) can be found as

l = √(r² + h²) = √((6ft)² + (8ft)²) = 10ft.

Substitute the values of r and l into the formula for lateral area: πrl = π × 6ft × 10ft = 60π ft².

So, the lateral area of the cone is 60π square feet.

The length of a rectangle is 3 times its width. if the width is diminished by 1 inch and the length is increased by 3 inches. the area of the the new rectangle is 72 square inches. find the dimensions of the original rectangle.

Answers

Final answer:

The width of the original rectangle is 5 inches and the length is 15 inches.

Explanation:

Let's assume the width of the original rectangle is x inches. According to the problem, the length of the rectangle is 3 times its width, so the length of the original rectangle is 3x inches.

When the width is diminished by 1 inch, the new width becomes x - 1 inches. And when the length is increased by 3 inches, the new length becomes 3x + 3 inches.

The area of a rectangle is given by length multiplied by width, so we can set up the following equation:

(x - 1)(3x + 3) = 72

By multiplying out the terms and rearranging the equation, we get:

3x^2 + 6x - x - 3 = 72

Combining like terms and simplifying further:

3x^2 + 5x - 75 = 0

Solving this quadratic equation gives us two possible answers for x: x = -5 or x = 5.

Since the width cannot be negative, we discard the negative value of x. Therefore, the width of the original rectangle is 5 inches and the length is 3 times the width, which is 3 * 5 = 15 inches.

as per the given relation the value of g(x) for x = 2 is 4 and 4+1 = 5. Which makes that g(x) be not a function.

3) j(x) is not a function because the image of x = -4 is -3(-4) = 12 and 3.

4) h(x) is a function, because there is not any ambiguity in its definition, for every x in its domain there is only one image h(x).

Answer:

option c is correct

Step-by-step explanation:

The wheels on Annie's bicycle are $20$ inches in diameter. If each wheel makes $3$ full revolutions every second, then how many feet does Annie travel in $1$ second? Give your answer as an integer, rounded to the nearest foot.

Answers

we have that
diameter=20 in---------------> r=d/2--------> 20/2---------> r=10 in
[length of a circumference]=2*pi*r-------> 2*pi*10-------> 20*pi in

we know that
 1 revolution----------------> 20*pi in
3 revolutions (one second)----------------> X
X=3*20*pi---------> X=60*pi in  ( this is in one second)

1 foot--------------> is equal to 12 in
X-----------------> 60*pi in
X=60*pi/12--------> 5*pi ft------------> 15.708 ft---------> 16 ft (in one second)

the answer is
16 ft/sec

Final answer:

To calculate the distance Annie travels on a bicycle with 20-inch diameter wheels making 3 revolutions per second, use the formula for calculating distance traveled.

Explanation:

The diameter of the wheels is 20 inches, which means the radius is half of the diameter, so radius = 10 inches = 10/12 feet. Each wheel makes 3 revolutions per second.

To find how many feet Annie travels in 1 second, you can use the formula:

Distance traveled = 2 * pi * radius * number of revolutions per second.

Substitute the values into the formula and then round to the nearest foot to get the answer.

The answer is 0 feet.

A line passes through (–7, –5) and (–5, 4).Write an equation for the line in point-slope form.
--------
Slope m = diffy/diffx
m = 9/2
----

y - y1 = m*(x - x1) where (x1,y1) is either point.
Rewrite into any form.
================
Or,
| x y 1| |-7 -5 1| = 0 |-5 4 1| --- x*(-5-4) - y*(-7+5) + (-28-25) = 0

Answer:

The equation of the line in slope-intercept form is y = 92x + 532.

The equation of the line in standard form is 9x−2y=−53

 

Explanation:

The slope of the line passing through (−7,−5)and(−5,4) is m=y2−y1x2−x1=4+5−5+7=92

 

Let the equation of the line in slope-intercept form be y=mx +cory =92x+c The point (-7,-5) will satisfy the equation . So, −5=92⋅ (−7)+corc=632−5=532

 

Hence the equation of the line in slope-intercept form is y=92x+532.

 

The equation of the line in standard form is

y=92x+532.or2y=9x+53

 

or 9x−2y =−53 {Ans]
