What is the slope of the line through the points (2, 4) and (2, -11)?

Shkiper50 [21]

Answer:

The slope of the line would be undefined

Step-by-step explanation:

First you take the y of the second point and subtract it from the y of the first point. -11 - 4. That leaves you with -15. Then you take the x of the second point and subtract it from the x of the first point. that leaves you with 0. Then you put y over x. You then have -1`5/0. That is undefined.

Answer:

The correct option is A.

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let y be the profit (in millions) after x years.

From the given graph it is clear that the line passes through the point (1,-100).

The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).

The line passes through (1,-100) and (4,80). So, the equation of line is

$y-(-100)=\frac{80-(-100)}{4-1}(x-1)$

$y+100=\frac{180}{3}(x-1)$

$y+100=60(x-1)$

$y+100=60x-60$

Subtract 100 from both sides.

$y+100-100=60x-60-100$

$y=60x-160$

The function form is

$f(x)=60x-160$

Therefore, the correct option is A.

The global surface water area is 361, 132,000 square metres. Calculate the volume of water needed to cause a 3mm in sea level.

vovangra [49]

Answer:

The volume of water is 396 cubic meter.

Step-by-step explanation:

Area of water, A = 132000 square meter

Height, h = 3 mm = 0.003 m

The volume of water is given by

V = Area x height

V = 132000 x 0.003

V = 396 cubic meter.
