Answer:

The speed of the aircraft is 126.667 miles per hour.

Step-by-step explanation:

Let suppose that aircraft travels at constant speed. From Mechanical Physics, we understand speed as travelled distance divided by time. In this case, the absolute speed of the aircraft is the sum of wind speed and speed of the aircraft relative to wind. That is:

Tailwind (Wind flows in the same direction of aircraft)

[tex]t = \frac{s_{T}}{v_{W,T}+v_{A/W,T}}[/tex] (Eq. 1)

Headwind (Wind flow in the direction opposite to aircraft)

[tex]t = \frac{s_{H}}{v_{W,H}+v_{A/W,H}}[/tex] (Eq. 2)

Where:

[tex]s_{T}[/tex], [tex]s_{H}[/tex] - Travelled distances on tailwind and headwind conditions, measured in meters.

[tex]v_{W,T}[/tex], [tex]v_{W,H}[/tex] - Tailwind and headwind speeds, measured in meters per second.

[tex]v_{A/W,T}[/tex], [tex]v_{A/W,H}[/tex] - Relative speeds of aircraft relative to tailwind and headwind, measured in meters per second.

We proceed to equalize both expressions to eliminate time:

[tex]\frac{s_{T}}{v_{W,T}+v_{A/W,T}} = \frac{s_{H}}{v_{W,H}+v_{A/W,H}}[/tex] (Eq. 3)

If we know that [tex]s_{T} = 360\,mi[/tex], [tex]s_{H} = 300\,mi[/tex], [tex]v_{W,T} = 10\,\frac{mi}{h}[/tex], [tex]v_{W,H} = -10\,\frac{mi}{h}[/tex] and [tex]v_{A/W,T} = v_{A/W,H}[/tex], then:

[tex]\frac{360}{v+10} = \frac{300}{v-10}[/tex]

The relative speed of the aircraft is now cleared:

[tex]360\cdot (v-10)=300\cdot (v+10)[/tex]

[tex]360\cdot v-3600 = 300\cdot v +3000[/tex]

[tex]60\cdot v = 7600[/tex]

[tex]v = 126.667\,\frac{mi}{h}[/tex]

The speed of the aircraft is 126.667 miles per hour.

For parallel lines, gradients (slope) must be the same.

The lines given in multiple choice, no line with the same gradient/slope as line y = 3x - 2.

Step-by-step explanation:

From y = 3x - 2,

The slope = 3

Let's check slopes of lines from multiple choice:

From first line

4x + 2y = 5

2y = -4x + 5 (dived 2 both sides)

y = - 2x + 5/2

The slope = -2

Continue with remaining three equations you get slopes: -1/2, -4 and 4.

Hence no equations above represent parallel equation to y = 3x - 2

The mean absolute deviation of the data set of 15.2

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.

Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Given is a data set, we need to find the mean absolute deviation for the group,

So,

The mean = 38+45+76+93+50+54+29+44+62+31 / 10

= 522/10 = 52.2

Now finding the absolute deviation =

|52.2-38| = 14.2

|52.2-45| = 7.2

|52.2-76| = 23.8

|52.2-93| = 40.8

|52.2-50| = 2.2

|52.2-54| = 1.8

|52.2-29| = 23.2

|52.2-44| = 8.2

|52.2-62| = 9.8

|52.2-31| = 21.2

The mean absolute deviation = 14.2 + 7.2 + 23.8 + 40.8 + 2.2 + 1.8 + 23.2 + 8.2 + 9.8 + 21.2 / 10

= 152.4 / 10

= 15.24

≈ 15.2

Hence, the mean absolute deviation of the data set of 15.2

Step-by-step explanation:

The zeros after 8 are not significant.

Answer:

0.5

Step-by-step explanation:

We have to find a  number which is greater than the absolute value of -3/8.

Absolute value of -3/8 = 3/8

3/8=0.375

Now, we have to find a number which is greater than 0.375

1/4=0.25

0.25 is smaller than 0.375

0.5 is greater than 0.375

also -5/8 and -1/8 are less than 0.375

Hence, the only number which is greater than the absolute value of -3/8 is:

You will require 126 inches of ramp for a rise of 10.5

Evaluate the word problem

If your verticle rise is 10.5 inches for every 1 inch of that 10.5 you have 12 inches. This is written into an equation as follows;

x: How many inches of vertical rise you have,

y: Length of ramp required

y = 12x

Solve:

y = 12x

y = 12(10.5)

y = 126 inches of ramp

A. The parent function reflect across x-axis.

A relation between set of inputs & set of outputs is called function. In a function, for each element of input set there is exactly one element of the set of outputs.

The simplest form of a family of functions is called the parent function. A family of functions always share same highest degree & shape.

If a function has an algebraic expression in absolute value symbols, then the function is called absolute value function.

The parent function y = |x| always go downwards & hence the curve opened upward.
