Are you looking for D on the graph? if so, then the final coordinate to complete the rectangle is (-2,-8)

Any and all help would be appreciated!

SpyIntel [72]

The way we can find out the unit rate (also known as the <em><u>SLOPE</u></em>) is by using the table as coordinates!

The slope formula is $\frac{y2 - y1}{x2 -x1}$

With the table, the TIME column can be "x"

The DISTANCE column can be "y"

____________________________

As coordinates, it would look like...

(0,0)

(20, 25)

(30, 37.5) and so on!

_____________________________

All we need to do now is use 2 of these coordinates and plug them into the slope formula in their correct places to find the unit rate!

Example:

solve!

$\frac{37.5 - 25}{30 - 20}$ = 12.5/10 ⇒ 1.25 ( or 5/4 in fraction form)

Write an equation that is perpendicular to y= 1/2x+5 and passes through (4,8)

goblinko [34]

Answer:

y = -2x + 16.

Step-by-step explanation:

The slope of the perpendicular line = -1 / slope of the given line

= -1 / 1/2 = -2.

Using the point slope form of the equation of a straight line:

y - y1 = m (x - x1)

y - 8 = -2(x - 4)

y - 8 = -2x + 8

y = -2x + 16 is the required equation.

After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil ide

dimaraw [331]

Answer:

The revised probabilities are;

The probability of finding soil with oil = 0.8

The probability of finding soil with good oil = 0.16

The probability of finding medium quality oil = 0.64

Step-by-step explanation:

The given probability of finding soil with high quality oil, P(QO) = 0.20

The probability of finding soil with medium-quality oil, P(OM) = 0.80

The probability of finding soil with no oil, P(ON) = 0.2

Therefore, given that the probability of finding soil with no oil = 0.2, we have;

The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil

P(OP) = 1 - 0.2 = 0.8

Which gives;

The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;

P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16

The probability of finding good oil = 0.16

Similarly;

The probability of finding medium quality oil P(FM) = P(OM) × P(OP) = 0.8 × 0.8 = 0.64

Which gives the revised probability as follows;

The probability of finding soil with oil, P(OP) = 0.8

The probability of finding soil with good oil, P(FG) = 0.16

The probability of finding medium quality oil, P(FM) = 0.64.
