The position of a diving bell is −3/4 mile relative to sea level. The diving bell reached this position after dropping from sea

level at a constant rate for 1 1/2 hours. What was the position of the diving bell relative to sea level 1 hour after it began its descent? Enter your answer in the box.

<span>After 1 hour, the diving bell was -1/2 mile relative to sea level. Since the rate of decent is constant, we can use two ratios to represent the depth at 2 different times. To make things easier to write, I'll use decimals to represent time and depth. -.75 / 1.5 = x / 1 Now solve for x -0.5 = x So after 1 hour, the diving bell was -1/2 mile relative to sea level.</span>

Answer (numbers needed in boxes, going from top to bottom):

1

-1

-3

3

Step-by-step explanation:

f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.

1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:

y = 2(1)-1\\y = 2 - 1\\y = 1\\

So, when x equals 1, y equals 1. Therefore, the first box on the top must be filled out with the number 1.

2) Do the same with the rest of the x values. Here are the steps to solve each one, going in order from the top towards the bottom:

x = 0

y = 2(0) - 1\\y = 0 - 1\\y = -1

x = -1

y = 2(-1) - 1\\y = -2 -1 \\y = -3\\

x = 2

y = 2(2)-1\\y = 4-1\\y = 3\\

Three charges are arranged in an equilateral triangle with sides of 4 cm. The coordinates and corresponding charge values are as
lisov135 [29]
To determine the answer of Part A draw the equilateral triangle and the to determine the coordinates of of the third charge use that triangle.
To calculate the gravitational field strength in part B from each of the charges use the following equation.

E=kcq/r2

If you would add those values then you can use the symmetry about the y axis to make the vector addition a litter easier.<span />

Identify Arithmetic Mean, Geometric Mean and Harmonic Mean from the following averages: 56.4, 59.8 and 55.8
photoshop1234 [79]
If you would like to calculate the arithmetic mean, geometric mean, and harmonic mean from the following averages, you can calculate this using the following steps:

averages: 56.4, 59.8, 55.8
the number of values: 3

arithmetic mean:
(56.4 + 59.8 + 55.8) / 3 = 57.33

geometric mean:
(56.4 * 59.8 * 55.8)^(1/3) = 57.31

harmonic mean:
3 / (1/56.4 + 1/59.8 + 1/55.8) = 57.28
