Answer:

52,500

Step-by-step explanation:

We can convert the word problem into an equation:

1.36x= 71,400

x represents the number of people in the previous population

We divide both sides by 1.36

x=52,500

The previous population was 52,500!

Hope this helps!

Answer:

3rd Option

Step-by-step explanation:

Since the denominator cannot equal 0, x ≠ 5. Therefore, our domain stops and starts again at 5. So our answer is 3rd option.

The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing [tex]R_0, 270^{\circ}[/tex] is not correct as we don't rotate 270 degrees counterclockwise.

The solution is Option A.

The rotation angle is given by R0 ( 90° )

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the triangle be represented as ABC

The coordinate of A = A ( 1 , 4 )

The coordinate of B = B ( 3 , 4 )

The coordinate of C = C ( 3 , 2 )

Now , when the triangle ABC is rotated 90° counterclockwise rotation: (x,y) becomes (-y,x)

Substituting the values in the equation , we get

The coordinate of A' = A' ( -4 , 1 )

The coordinate of B = B ( -4 , 3 )

The coordinate of C = C ( -2 , 3 )

Hence , the rotation is 90° counterclockwise

Answer:

A.) gf(x) = 3x^2 + 12x + 9

B.) g'(x) = 2

Step-by-step explanation:

A.) The two given functions are:

f(x) = (x + 2)^2 and g(x) = 3(x - 1)

Open the bracket of the two functions

f(x) = (x + 2)^2

f(x) = x^2 + 2x + 2x + 4

f(x) = x^2 + 4x + 4

and

g(x) = 3(x - 1)

g(x) = 3x - 3

To find gf(x), substitute f(x) for x in g(x)

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

gf(x) = 3x^2 + 12x + 12 - 3

gf(x) = 3x^2 + 12x + 9

Where

a = 3, b = 12, c = 9

B.) To find g '(12), you must first find the inverse function of g(x) that is g'(x)

To find g'(x), let g(x) be equal to y. Then, interchange y and x for each other and make y the subject of formula

Y = 3x + 3

X = 3y + 3

Make y the subject of formula

3y = x - 3

Y = x/3 - 3/3

Y = x/3 - 1

Therefore, g'(x) = x/3 - 1

For g'(12), substitute 12 for x in g' (x)

g'(x) = 12/4 - 1

g'(x) = 3 - 1

g'(x) = 2.

Option "C" is the correct answer to the following question.

Step-by-step explanation:

Given:

Number of people speak Mandarin = 1,000 million (Approx)

Number of people speak Hindi = 500 million (Approx)

Find:

Number of people more speak Mandarin.

Computation:

Number of people more speak Mandarin = Number of people speak Mandarin - Number of people speak Hindi

Number of people more speak Mandarin = 1,000 million - 500 million

Number of people more speak Mandarin = 500 million

I believe your answer might be

D) About 550 million more people speak Mandarin than speak Hindi.  

Answer:

Attached pleased find the screen grab of the graph with the line y = x - 4 included

The solution of the system of equations, y = x² - 4·x and y = x - 4 is directly found from the graph by the points of the intersection of the lines y = x² - 4·x and y = x - 4 which are (4, 0) and (1, -3)

x = 1 y = -3

or

x = 4 y = 0

Step-by-step explanation:

To verify, we have;

Equations y = x² - 4·x and y = x - 4 can be solved where they are equal as follows

Thus equating the value of y in both equations gives;

x² - 4·x  = x - 4

x² - 4·x -x - 4 = 0

x² - 5·x  + 4 = 0

(x - 4) × (x - 1) = 0

Therefore; x = 4 or 1

When x = 4, y = x - 4 = 1 - 4 = -3.

Step-by-step explanation:

Let the rhombus be $ABCD$, where $\angle DAB = 120^\circ$. Then $\angle ABC = 180^\circ - \angle DAB = 180^\circ - 120^\circ = 60^\circ$.

[asy] unitsize(1 cm); pair A, B, C, D; A = (0,1); B = (sqrt(3),0); C = (0,-1); D = (-sqrt(3),0); draw(A--B--C--D--cycle); draw(A--C); label("$A$", A, N); label("$B$", B, E); label("$C$", C, S); label("$D$", D, W); label("$6$", (A + D)/2, NW); [/asy]

Since $AB = BC$, triangle $ABC$ is equilateral. By the same argument, triangle $ACD$ is also equilateral. Each triangle has area

\[\frac{\sqrt{3}}{4} \cdot 6^2 = 9 \sqrt{3},\]so the area of the rhombus is $2 \cdot 9 \sqrt{3} = \boxed{18 \sqrt{3}}$.

The exponential function represented by the values is f(x) = 4(0.5)ˣ.

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

From the table, at point (0, 4):

4 = ab⁰

a = 4

At point (2, 1):

1 = ab²

1 = 4b²

b² = 0.25

b = 0.5

The exponential function represented by the values is f(x) = 4(0.5)ˣ.

After folding the piece of paper, the result will be 1/4 the size of the original square.

Answer:

Yes, you are as far as I can tell it looks right to me,

Answer:

I would use the pounds.

Step-by-step explanation:

The reasoning behind using the pound is, if you are using fractions per say to get a side by side ration when you are doing 16 ounces to 1 pound you would want to have a unit rate.

750 ounces          16 ounces

-------------------       -----------------    

  x pounds              1 pound

Do you see how much easier it is to convert from ounces to pounds when you have a unit rate? Now once you see how many times you had to multiply 16 to get 750 you can easily multiply that number by 1!

Answer: 11 balls

For x intercepts, plug in 0 for y.

               0 = (x^2) - 2x - 35

*factoring* = (x-7)(x+5)

x intercepts = 7,-5

As for the vertex, you can use the equation -b/2a for the x-coordinate of the vertex

so,

x = -b/2a = -(-2)/2 = 1

then just find the y value by plugging it back in to the equation.

y = ((1)^2) - 2(1) - 35

= -36

so, vertex is at (1,-36)

Answer:

Applies are £0.50 each and bananas £0.80 each.

Step-by-step explanation:

Represent the numbers of apples and bananas by a and b respectively.

Then:

5a + 4b = £5.70, and:

4a + 2b = £3.60

Let's solve this system using elimination by addition/subtraction.  Multiply the 2nd equation by -2, obtaining the equivalent system

5a + 4b = £5.70

-8a  - 4b = -£7.20

--------------------------

-3a         =  -£1.50

Dividing both sides by -3, we get £0.50.  Apples are £0.50 apiece.

How much are bananas per piece?  Use the first equation; substitute £0.50 for a:

5(£0.50) + 4b = £5.70, or

                  4b = £3.20.  Then b = £0.80.

Applies are £0.50 each and bananas £0.80 each.

Step-by-step explanation:

In the question, it says that her coach wants her to run 2 1/2 TIMES the original 3/4 she had ran. Therefore, you would want to make the fractions into improper fractions, and then multiply, which is how you would get 13/4 * 5/2.

Answer:

Option C.

Step-by-step explanation:

It is given that Tatiana made a two-way table to describe what her friends like at the amusement park.

Two way table represents the data for two categorical variables. The categories are labeled at the top and the left side of the table.  

In the given case, water rides labeled on the top and roller coasters  labeled on left side.  Row represents one variable and column represents the other.

Tatiana two-way table is in the form of below table:  

                                          likes water rides       doesn’t like water rides  

likes roller coasters                           a                          b

doesn’t like roller coasters               c                          d

where, a, b, c and d are constant.

columns: likes roller coasters, doesn’t like roller coasters; rows: likes water rides, doesn’t like water rides  

Therefore, the correct option is C.

12-3*y = 0

Subtract 12 from both sides:

-3 * y = -12

Divide both sides by -3:

y = 4

Answer:

y=4

Step-by-step explanation:

Standard form:

−3y + 12 = 0

Factorization:

−3(y − 4) = 0

Solutions:

y = 12/3   = 4

Isolate the variable by dividing each side by factors that don't contain the variable:

y=4
