What is the first term of the quotient of the following division problem? (x3 – 1) ÷ (x + 2)

Answer:

The mode is 10.

Step-by-step explanation:

A mode is basically the number that occurs most in a data set, so first to make it easier you can list the number least to greatest. After that look at the data set and see what number occurs the most. In this situation it is 10 because it occurs 3 times.

In a data set, the mode is the value that appears the most frequently. A set of data can have just one mode, multiple modes, or none at all.

To solve mode given series is

[tex]10\\16\\15\\14\\8\\21\\10\\5\\19\\18\\4\\5\\16\\12\\10\\9\\[/tex]

Rearranging series we get

[tex]4\\5\\5\\8\\9\\10\\10\\10\\12\\14\\15\\16\\16\\18\\19\\21\\[/tex]

hence, mode is number with highest frequency which is 10 in this series

Answer:

The answer is 6 cups of flour.

To find the amount of flour needed for 3 sticks of butter, a proportion based on the original recipe ratio is used, resulting in 6 cups of flour.

Jermiah's recipe calls for 1 1/2 cups of flour for every 3/4 stick of butter. Therefore, if he uses 3 sticks of butter, we need to find out how many cups of flour that corresponds to.

To determine the amount of flour needed, we set up a proportion, where the original amount of butter and flour are proportional to the new amount of butter and flour.

Since 3/4 stick of butter corresponds to 1 1/2 cups of flour, 3 sticks of butter would be 4 times as much, because 3 divided by 3/4 equals 4. Therefore, he will need 4 times the original amount of flour.

Here is the math: 1 1/2 cups of flour x 4 = 6 cups of flour.

Answer:

A) 12,14,16

B) 3x+1=16

Step-by-step explanation:

A)

They already gave you the equation to solve:

n+(n+2)+(n+4)=42

n+n+2+n+4=42

Put like terms together:

n+n+n+2+4=42

Combine the like terms:

3n+6=42

Subtract 6 on both sides:

3n=42-6

Simplify:

3n=36

Divide both sides by 3:

n=36/3

Simplify:

n=12

If n=12,

then

n+2=14 and

n+4=16.

Check the addition of those numbers: 12+14+16=26+16=42.

B)

There is a lot of equations that have a solution of 5.

It might be good start with x=5.

Then just remember whatever you do to one side, you must do to the other.

x=5

Multiply both sides by 3:

3x=15

Add 1 on both sides:

3x+1=16

An example of equation that solution 5 is 3x+1=16.

Answer:

30√3 - 21 √6

Step-by-step explanation:

The given expression is:

3√2 (5√6 -7√3)

We cannot subtract the values inside the bracket because the values inside the radicals are not same.

So multiply 3√2 with the bracket.

=3*5√2*6 -  3*7√2*3

=15√12 - 21√6

Now break √12

=15√4*3 - 21√6

write √4*3 separately:

=15√4 *√3 - 21√6

We know that √4 = 2

=15*2*√3 - 21√6

=30√3 - 21 √6

Therefore the answer is 30√3 - 21 √6 ....

To find the percetage of data points that lie between the points -3.01 and 2.61, on a normal distribution we're going to need the help of a calculator. The result is: 99.42%

Attached you will find the graph that represents the result.

Answer:

y=5/4x-4

Step-by-step explanation:

C. y = 5/4x - 4.

One of the three ways we may express a straight line is in slope-intercept form. The other forms are known as point slope form and standard form, however in this section we will mostly use slope-intercept form. The slope-intercept form is used to write a line's equation as y = mx + c.

You may be aware that a point's coordinates on a graph are x and y.

Given two coordinates of a line from that, we can calculate the slope.

slope m = (y₂ - y₁)  /  (x₂- x₁)

m = 5/4

Put the value of m and one coordinate value in the slope-intercept equation

-4 = 5/4 * 0 + c

c = -4

therefore slope-intercept equation of given coordinates is y = 5/4x - 4.

In a scale model, Figure A has one side measuring 45 units and another side measuring x, while Figure B has corresponding sides of 27 and 18 units. By setting up a proportion, x is determined to be 30 units.

To find the value of x, we can set up a proportion based on the given information:

In Figure A, one side is 45, and in Figure B, it corresponds to a side of 27.

In Figure A, the other side is x, and in Figure B, it corresponds to a side of 18.

So, we can set up the following proportion:

(45 / 27) = (x / 18)

Now, cross-multiply and solve for x:

45 * 18 = 27x

810 = 27x

Now, divide by 27 to find the value of x:

x = 810 / 27

x = 30

So, the value of x is 30.

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the sector of circle of angle 68.9 degrees minus the area of the isosceles triangle

step 1

Find the area of sector of the circle

The area of circle is equal to

[tex]A=\pi r^{2}[/tex]

assume

[tex]\pi =3.14[/tex]

[tex]r=9.28\ cm[/tex]

substitute

[tex]A=(3.14)(9.28)^{2}[/tex]

[tex]A=270.41\ cm^{2}[/tex]

Remember that the area of a circle subtends a central angle of 360 degrees

so

using proportion Find out the area of a sector with a central angle of 68.90 degrees

Let

[tex]270.41/360=x/68.90\\\\x=68.90*270.41/360\\\\x=51.75\ cm^{2}[/tex]

step 2

Find the area of the isosceles triangle

Applying the law of sines

The area is equal to

[tex]A=(1/2)r^{2}sin(68.90)[/tex]

we have

[tex]r=9.28\ cm[/tex]

substitute

[tex]A=(1/2)(9.28)^{2}sin(68.90)=40.17\ cm^{2}[/tex]

step 3

When x≈2.7, the graphs of f(x) and g(x) intersect

f(x)=g(x) when x=0

Step-by-step explanation:

The graphs of two function y=f(x) and y=g(x) are shown in attached diagram.

These two graphs intersect at two points (0,-3) and about (2.7,2.3). This means that

f(0)=g(0)=-3

and

f(2.7)=g(2.7)=2.3

So, x=0, y=-3 is the solution to the system (the solution to the system is ordered pair (x,y), not only x)

Points (1.5,0) and (2,0) are not solutions, because they are not points of graphs intersection.

When x≈2.7, the graphs of f(x) and g(x) intersect (TRUE)

f(x)=g(x) when x=0 (TRUE)

Answer:

f(x)=g(x) when x=0.

x=0 is a solution to the system.

When x≈2.7, the graphs of f(x) and g(x)intersect because they are equal to each other at that value.

Answer:

Area of the polygon = 59 in²

Explanation:

From the given diagram, we can note that the given polygon is composed of an upper triangle, a side triangle and a rectangle

Therefore:

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

1- getting the area of the upper triangle:

We have:

base of triangle = 7 in

height of triangle = 6 in

Therefore:

Area of upper triangle = [tex]\frac{1}{2}*base*height = \frac{1}{2}*7*6=21[/tex] in²

2- getting the area of the side triangle:

We have:

base of triangle = 4 in

height of triangle = 5 in

Therefore:

Area of upper triangle = [tex]\frac{1}{2}*base*height = \frac{1}{2}*4*5=10[/tex] in²

3- getting the area of the rectangle:

We have:

length of rectangle = 7 in

width of rectangle = 4 in

Therefore:

Area of rectangle = length x width = 7 x 4 = 28 in²

4- getting the total area of the polygon:

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

Therefore:

Area of polygon = 21 + 10 + 28 = 59 in²

Step-by-step explanation:

So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.

So that means we have x^2=10(14+10).

After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.

To get rid of the square on the x, we square root both sides.

x=sqrt(240)

x=15.49193338

To the nearest tenths, the answer is x=15.5

So 15.5 inches is the length of x.
