f(x) = 2x - 2
Which graph represents the inverse of function f

Answer:

c

Step-by-step explanation:

If I'm correct, you're asking which variable is the dependent variable y from the question

Answer and explanation:

The equation can be modelled:

y= 1.5x

Where y is the current length of the hair

x is the number of months of hair growth

We can see from the equation therefore that y is a dependent variable that depends on x the independent variable, the number of months, to get a value. In other words given that her hair grows at a constant rate of 1.5 inches per month, her hair length is based on number of months x of growth in inches of hair.

Answer:

98 x 3 = 294 or 3 x 98 = 294

Step-by-step explanation:

Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:

3 x 98 = 294

We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.

Step-by-step explanation:

The best way to select the 100 phone calls would be to randomly select the same amount of phone numbers from each individual type of business. This would make sure that there are no bias choices and would be 100% representative of the overall business market in every single type of business. If you choose the first 100 phone numbers you are choosing from only a handful of the same types of business and leaving out a lot of other types of business. This makes it impossible for the information gathered to be representative of the entire market.

Answer:

Circumference of a circle   is C=2 pi r =2(3.1415) (6.7500)=42.4575

Step-by-step explanation

C= 42.4575 , now round to the nearest 1000th...= 42.5000

Answer:

. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

(which is the same as the number of sides).

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

2. 540°

Sum of Interior Angles of a Polygon

A pentagon has five sides, thus the interior angles add up to 540°, and so on.

Answer:

The height of the storage tank would be approximately 1.2 m.

Step-by-step explanation:

The cattle drink 3 cubic meters of water each day.

For 5 days,

the cattle would drink = 3 cubic meters x 5

                                      = 15 cubic meters of water

Thus,

The volume of the storage tank = 15 cubic meters

But,

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

where r is the radius and h the height.

So that,

15 = [tex]\frac{22}{7}[/tex] x [tex]2^{2}[/tex] x h

15 = [tex]\frac{22}{7}[/tex] x 4 x h

15 = 12.57h

h = [tex]\frac{15}{12.57}[/tex]

  = 1.1933

h = 1.2 m

The height of the storage tank would be approximately 1.2 m.

Answer:

23 m and 15 m

Step-by-step explanation:

THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?

Let the height of the rectangle is h.

Base = 8+h

Area of the rectangle, A = 65 m²

We need to find the base and height of the rectangle. The area of a rectangle is given by :

A = bh

So,

[tex]65=(8+h)\times h\\\\65=8h+h^2\\\\h^2+8h-65=0\\\\(h-5)(h+13)=0\\\\h=5\ m\ \text{and}\ x=-13\ m[/tex]

Neglecting negative value, h = 15 m

Base  = 8+15 = 23 m

So, the base and height of the rectangle is 23 m and 15 m respectively.

Answer:

Month since April                                   Number of Ants

          0                                                         10,000

           1                                                         30,000

          2                                                         90,000

          3                                                        270,000

          4                                                         810,000

Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.

0 months from April = 10,000 * 1 = 10,000 ants

1 month from April = 10,000 * 3 = 30,000 ants

2 months from April = 30,000 * 3 = 90,000 ants

3 months from April = 90,000 * 3 = 270,000 ants

4 months from April = 270,000 * 3 = 810,000

Step-by-step explanation:

Given :

The scale of a model train is 1 inch to 13.5 feet.

One of the cars of the model train is 5 inches long.

To Find :

The length, in feet, of the actual car.

Solution :

It is given that scale of the model is 1 inch to 13.5 feet. It means that 1 inch in the actual scale is equal to 13.5 feet in real.

So, length of car real is :

Length = 5 × 13.5 feet

Length = 67.5 feet

Therefore, the length of the actual car is 67.5 feet.

Step-by-step explanation:

Answer:

12.8 units

Step-by-step explanation:

Adding a diagonal makes it into 2 of the same right-angled triangles.

In right angled triangles, you can use Pythagoras' therorem which says that a^2+b^2=c^2 where a and b are the shorter sides and c is the diagonal.

This means that 8^2+10^2=diagonal^2=64+100=164

The diagonal is then the square root of 164 which equals 12.806248...

Answer:

18

Step-by-step explanation:

continuous function

is correct :D

Answer:

That is the format for a slope so you already have it but its incorrect

Step-by-step explanation:

Slope format is y=mx+b

Your x shouldnt be next to the 3

This question isnt accurate or your missing information

====================================================

Explanation:

Because we can add two numbers in any order, the equation y = -1+3x is the same as y = 3x+(-1).

Compare this to y = mx+b, which is slope intercept form.

We see that m = 3 is the slope and b = -1 is the y intercept.

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches
