Urgent ASAP!! Imagine math

Paraphin [41]

Answer:

Graph A = 20miles/gallon

Graph B = 20

Step-by-step explanation:

For graph A, to find the change you will need to choose two points from the graph (the easier the better)

So for example, I've chosen 40miles-2gallons (2, 40) and point 0 (0, 0)

Now you will need to remember the slope formula which is:

$m=\frac{y_2-y_1}{x_1-x_2}$

so your point (x1, y1) will be (0, 0)

and point (x2, y2) will be (2, 40)

so $m=\frac{40-0}{2-0}$

which is $m=\frac {40}{2} = 20$

and so you get that the slope will be 20 miles/gallon

For graph B, what they want you to see is that change of y/change of x means the same as change of miles/change of gallons since x is the gallons and y is the miles.

The black graph is the graph of y=f(x). Choose the equation for the red graph. Please help!!

yan [13]

Answer:

Step-by-step explanation:

The black graph is the graph of y=f(x).

The red graph is the reflection of the black graph across the y-axis.

A. $y=f(x-1)$ determines the translation of the graph $y=f(x)$ one unit to the right.

B. $y=f\left(\dfrac{x}{-1}\right)$ determines the reflection of the graph $y=f(x)$ across the y-axis.

C. $y-1=f(x),\ y=f(x)+1$ determines the translation of the graph $y=f(x)$ one unit up.

D. $\dfrac{y}{-1}=f(x),\ y=-f(x)$ determines the reflection of the graph $y=f(x)$ across the y-axis.

Hello, can you explain this topic im in 6th grade

Andrew [12]

Hello there I hope you are having a great day :)

The Topic Shifting digits:

Shifting digits - Putting a digit in a different place. For a example Take the number 358 you would exchange the number from the hundreds that would equal 838 this meaning that you what to make a bigger number than a small one.

Examples:

1. 358 equal 838

2. 204 equal 402

3. 188 equal 881

You are just making them smaller to a greater number :)

Hopefully that helps you :)

Given the following winning percentages of the teams in a league (for a single year) compute the within-season standard deviatio

Masja [62]

Answer:

(b) 0.251

Step-by-step explanation:

1. Standard deviation equation:

$SD=\sqrt{\frac{\sum\limits^N_i {(x_{i}-X)^{2} } }{N} }$

Where X is the mean of the data, and N the amount of data. Then, N=5

2. Estimate the Mean:

$X=\frac{0.750+0.750+0.200+0.600+0.200}{5}=\frac{2.5}{5}=0.5\\$

3. Caclulate Standard deviation:

$SD=\sqrt{\frac{{(0.750-0.500)^{2}+(0.750-0.500)^{2}+(0.200-0.500)^{2}+(0.600-0.500)^{2}+(0.200-0.500)^{2} } }{5} }$

$SD=\sqrt{\frac{0.315}{5} }=\sqrt{0.063}\\SD=0.251$

How to construct a triangle with side lengths 10 cm and 14 cm and an angle between them of 60 degrees.

Yuliya22 [10]

Answer:

We draw line AB which is perpendicular to the 14 cm side

Since Angle C is 60 degrees that makes angle CAB = 30 degrees

Triangle CAB is a 30 60 90 triangle so line CB is half the hypotenuse or 5 cm

Line BD equals 9 cm

Line AB^2 = 10^2 - 5^2 = 75

Line AD^2 = AB^2 + BD^2

Line AD^2 = 75 + 81

Line AD^2 = 156

Line AD = 12.4899959968

Line AB = Sqr root (75) = 8.6602540378

Angle D = arc sine (8.6602540378 / 12.4899959968)

Angle D = 43.898 degrees

Angle A = 180 - 60 - 43.898 = 76.102 degrees

Actually this could have been done a little easier by using the Law of Cosines and then the Law of Sines, but I just thought I'd show another way to solve this.
