How do you do this problem?

vazorg [7]

Production by Mexico is the same percentage (3%) of world production for the years of interest, so the relation is

... (mexico production) = 0.03 × (world production)

Then, dividing by 0.03, we get

... (mexico production)/0.03 = (world production)

The change in world production is the difference between the amounts for the two years, so is

... (production increase) = (2007 world production) - (2000 world production)

... = 24/0.03 - 18/0.03 = (24 - 18)/0.03

... = 6/0.03 = 200 . . . . million metric tons

The appropriate choice is (D) 200.

Whats the slope and the equation

vichka [17]

You can find the slope of a line by having two points. In this case we have 5 different point so we pick two.

so for the first one I will pick (2,17) and (7,37)

we use (y2-y1) / (x2-x1) this is rise over run

plug and chug to get slope.
(37-17)/(7-2)= 4

now use point slope using one of the point that we used to find the slope
y−b=m(x−a) or y-y1 = m (x-x1)

plug and chug again
m=4 ............ point (2,17)

y- 17 = 4 (x- 2)
y= 4x +10

hope this helps

PLEASE HELP ME WITH THIS KHAN ASAP I did 5 hours of Khan :(

Answer:

The functions have the same y-intercept.

OPTION C is correct.

Step-by-step explanation:

DEFINITIONS AND FORMULAS

The equation of a linear graph is given to be:

$y=mx+b$

Where m is the slope of the graph and b is the y-intercept.

To calculate the slope given a table, we can use the formula:

$m=\frac{y^{2}-y^{1} }{{}x^2 -x^1}$

SOLUTION

Function 1: The equation of the graph is given to be

$p=-\frac{3}{2}r-5$

Therefore, the y-intercept of the graph is given to be:

$b=-5$

Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.

On checking the graph, we can see that when r = 0, p = -5.

Therefore, the y-intercept is:

$b=-5$

ANSWER

The functions have the same y-intercept.

OPTION C is correct.

Find the area of the blue sector(s). The diameter of the wheel is 12

Ber [7]

We know that to find the area of the entire circle, we are going to use the equation:

$A=\pi r^{2}$

And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.

Now we can use this radius in the equation:

$A=\pi (6)^{2}$

$A=36\pi$

Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide $36 \pi$ by 5 to find the area of each section:

$\frac{36 \pi}{5} =7.2 \pi$

Each section has an area of $7.2\pi units^{2}$ or, using 3.14 for pi, $7.2*3.14=22.61units^{2}$ .

Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:

$22.61*2=45.22units^{2}$

Therefore, the answer is C) 45.2 $units^{2}$ .
