Which situation best represents causation?

I think the answer here would be D. When it rains several inches, the water level of the lake increases, because the word Causation means: the relationship between cause and effect; causality. If it rains a lot, it will cause the lake to increase.

Answer: D.when it rains several inches, the water level of a lake increases

Step-by-step explanation:

Causation indicates a relationship between two quantities where one quantity is directly affected by the other.

i.e. There should be a direct link between the variables.

From all the given options, option D represents causation since the occurrence of rain several inches is increasing the water level.

i.e water level is effected by rain, which is true.

Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)

QveST [7]

Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)$

So the midpoint of your segment is

$\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)$

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.

Write a formula that can be used to find the area of a sector of a circle explain and justify the formula you wrote

Airida [17]

Answer:

X/360 (r^2)

Step-by-step explanation:

If X is the number of degrees of the sector, then the area will be given by

X/360 *r^2

Where r^2 is the radius of the circle. The denominator of X is 360 because the degrees of a circle add up to 360

For instance, if the sector is half the circle, then we have

180/360 *r^2 (or 0.5(360)*r^2)

Recall the equation for a circle with center ( h , k ) (h,k) and radius r r. At what point in the first quadrant does the line w

garri49 [273]

Equation of this circle is
x^2 + (y - 2)^2 = 36
y = 2.5x + 2

Substitute for y in the equation of the circle:-

x^2 + (2.5x + 2 - 2)^2 = 36

x^2 + 6.25x^2 = 36

x^2 = 36 / 7.25

x = +/- 6 / 2.693 = +/- 2.228

when x = 2.228 y = 2.5(2.228) + 2 = 7.57 to nearest hundredth

when x = -2.228 y = 2.5(-2.228) + 2 = -3.57

So they intersect at 2 points but the intersect in the first quadrant is at (2.23, 7,57) to nearest hundredth.
