antiseptic1488 [7]3 years ago
7 0

Answer:

3/5 and 0.6 are the only ones.

Step-by-step explanation:

0.6 = 60%            -Simply multiply by 100

3/5 = 0.6 = 60%                 -Divide 3/5, then once again multiply by 100.

Slop: second one (2/1)

Y-intercept: first one

Explanation
Slop is rise over run so how much it goes up or down on the top and how much it goes our right on the bottom

Y-intercept is where the point intersects with the y line so what point is on the y line

When creating lines of best fit, do you believe that estimation by inspection of the equation is best or do you think it should
Alex73 [517]

Answer:

Estimation by inspection is better than trying to determine the line of best fit exactly

i) For a scatter plot : The use of estimation by inspection

ii) For a straight line graph : The exact determination method

Step-by-step explanation:

To create lines of best fit the estimation by inspection is better than trying to determine the line of best fit exactly .

This is because line of best fit only shows the trend of the data and in most cases it doesn't have to start from origin.

Scenarios :

i) For a scatter plot : The use of estimation by inspection

ii) For a straight line graph : The exact determination method

Part A: Billy rented a canoe at $14 for 2 hours. If he rents the same canoe for 5 hours, he has to pay a total rent of $29. Writ
zepelin [54]

Part A)

So we need the graph to pass through these points:

time = 2 and price=$14 -> (2,14)

time= 5 and price = $29 -> (5,29)

Standard form:

Ax+By = C

Let’s replace the points:

A*2+B*14=C

A*5+B*29=C

Let’s eliminate variables:

(A*2+B*14)-(A*5+B*29)=C-C

A*2+B*14-A*5-B*29=0

-3A-15B=0

-3A=15B

A=15B/-3

A=-5B

There are several numbers that verify this proportion. For example, if B=1, A=-5 (you can try others, there is not only 1 correct answer).

So we can make this equation:

-5x+y=C

Then we can calculate C using one point:

-5*2+14=C

-10+14=C

4=C

So one of the possible equations is: -5x+y=4

(Remember there are multiple correct answers for this item)

You can verify it with the other point:

-5*5+29=-25+29=4 ->OK

 

Part B)

Whatever you have found in Part A, you will find the same in Part B when you convert it to function notation. All you have to do is clear y:

-5x+y=4

y=4+5x

So the equation is: f(x)=4+5x


Part C)

First of all, you have to find f(0)

f(x)=4+5x

f(0) =4+5*0=4+0=0

f(0) is ALWAYS the constant not multiplied by x.

So you know it has to cross the y axes in y=4

Now let’s put 0 as y-value:

4+5x=0

5x=0-4=-4

x=-4/5

So now you know it has to cross the x axes in x=-4/5.

So you can put those intersections in the graph and you draw the line through those points. Labels: horizontal axes is x, and in this case represents time; vertical axes is y, and in this case represents price.

Remember there are other methods, too :)

The graph shows how many centimeters above a table top, y, a painted spot on an automated hamster wheel is for a given number of
ale4655 [162]

Answer:

Hence, the answer is 86.42°.

Step-by-step explanation:

We are asked to find how many degrees is the painted spot turning in 0.75 s.

Let us consider that α denote the angle spot is turning in 0.75 sec.

As in 0.75 sec the height of table top is 12.

Hence we can use the trignometric identity to find the measure of angle α.

as \tan\alpha=\dfrac{P}{B}

where P denotes the perpendicular i.e. the height of table top.

and B denotes the base i.e. the number of seconds.

Here P=12 and B=0.75

Hence, \tan\alpha=\dfrac{12}{0.75}=16\\\\\alpha=\arctan 16=86.42 \degree
