_______ __________

0 - 1 --------------> 1

1 - 2 --------------> 5

2 - 3 --------------> 5

3 - 4 --------------> 2

4 - 5 --------------> 1

For frequencies, just count the data values in each interval

A drone is monitoring the atmospheric conditions above a farm field.

Viefleur [7K]

Answer:

$y=5 \ \ \ x x_o + 1.9s$

Step-by-step explanation:

This situation can be considered as a piecewise function. First, you take xo as the time in which the drone goes upward. Before this time the height of the drone is constant with a value of 5 m. Next, you take into account that during 1.9 s after xo the drone accelerates. Finally, the drone flies again with a constant height of 5.9m. Hence, this function has three parts:

For the first part you have:

y = 5 for x < xo

For the second part you first calculate vertical speed (which means the slope of the linear function) by using the following kinematic equation:

$y=vx\\\\v=\frac{y-y_o}{x}=\frac{5.9m-5.0m}{1.9s}=0.47m/s$

Then you have:

y = 0.47x for xo < x < xo + 1.9s

And for the third part:

y = 5.9 for x > xo + 1.9s

Summarizing you obtain:

$y=5 \ \ \ x x_o + 1.9s$

Step-by-step explanation:

Step 1: Define

Identify

2(4 + 2x) ≥ 5x + 5

Step 2: Solve for x

[Distributive Property] Distribute 2: 8 + 4x ≥ 5x + 5
[Subtraction Property of Equality] Subtract 5x on both sides: 8 - x ≥ 5
[Subtraction Property of Equality] Subtract 8 on both sides: -x ≥ -3
[Division Property of Equality] Divide -1 on both sides: x ≤ 3

Solve for x. 3x/4 - X/12 =7/8 simplify your answer in fraction form

Usimov [2.4K]

Answer:

7/3

Step-by-step explanation:

or, 3x/4 - 7/8 = 7/8

or, 3x/4=7/8+7/8

or, 3x/4 = (7+7)/8

or, 3x/4 = 14/8

or, 3x = (14/8)*4

or, 3x=56/8

or, 3x= 7

or, x=7/3
