Which situation best represents causation?

2 answers:

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.

(2 x 106) x (0.00009) = ?

RSB [31]

I think you meant to write

(2 × 10⁶) × 0.00009

First, convert 0.00009 to scientific notation:

0.00009 = 9 × 10 ⁻⁵

Then

(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)

… = (2 × 9) × (10⁶ × 10 ⁻⁵)

… = 18 × 10¹

… = 1.8 × 10²

Jim leaves the gym running 5 mph. Ten minutes later Bob leaves the gym on his bike traveling at a speed of 8 mph. how long will

podryga [215]

Answer:

26 2/3 minutes: The two boys meet after 26 2/3 minutes

Step-by-step explanation:

Distance covered by Jim = Distance covered by Bob

(5 mph)(t) = (8 mph)(t - 10)

Simplify this by performing the indicated multiplication:

(5 mph)(t) = (8 mph)(t) - 80 mi

or:

80 mi = (3 mph)(t), or

80 mi

t = ----------- = 26 2/3 minutes

3 mph

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), i

pychu [463]

Set the function to equal zero:

$-x^2 - 5x + 50 = 0$

To find the zeros, or solutions, to this problem, we will use the quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Plug the values into the equation:

$a = -1, b = -5, c = 50$

$x=\frac{5\pm\sqrt{-5^2-4(-1)(50)}}{2(-1)}$

$x=\frac{5\pm\sqrt{25+200}}{-2}$

$x=\frac{5\pm15}{-2}$

Solve for both plus and minus:

$\frac{5 + 15}{-2} = \frac{20}{-2} = -10$

$\frac{5 - 15}{-2} = \frac{-10}{-2} = 5$

$x = -10, x = 5$

The question cannot use a negative value for x, as the diver cannot dive a negative distance from the board.

The answer is '<span>x = 5; the diver hits the water 5 feet away horizontally from the board', because x represents the horizontal distance away from the board.</span>
