The graph would stay at 2 inches. It falls steadily all day so it would stay 2.(i also got right on quiz)

think of it like this, after 1 hour there is 2 inches of rain, after 2 hours there is 4 inches of rain, and after 10, there should be 20, so, as it runs 1 it should rise 2.

68.64 divided by 2.4 SHOW WORK PLEASE

34kurt

Answer:28.6

I started by seeing how many 2.4 can go into 68.64. I found that it is pretty easy to find that if you multiply the 2.4 by ten you get 24 so we do that twice and have 48. We then subtract 48 from the 68.64 which leaves us with 20.64. If we multiply 2.4 by 5 we get 12 so once again subtract 12 from that 20.64 and now we are left with 8.64. So now we need to figure out how many more 2.4 are left well it is more than three because three gives us 7.2 so let’s subtract that from it now we are left with 1.44. Now we need to find out what times 2.4 gives us 1.44. Well it would be .6. So now if we add up everything we get the answer of 28.6. Sorry if this very complicated

Pls Help!!! Worth 99 Pts!!

Sladkaya [172]

Answer:

First, for end behavior, the highest power of x is x^3 and it is positive. So towards infinity, the graph will be positive, and towards negative infinity the graph will be negative (because this is a cubic graph)

To find the zeros, you set the equation equal to 0 and solve for x

x^3+2x^2-8x=0

x(x^2+2x-8)=0

x(x+4)(x-2)=0

x=0 x=-4 x=2

So the zeros are at 0, -4, and 2. Therefore, you can plot the points (0,0), (-4,0) and (2,0)

And we can plug values into the original that are between each of the zeros to see which intervals are positive or negative.

Plugging in a -5 gets us -35

-1 gets us 9

1 gets us -5

3 gets us 21

So now you know end behavior, zeroes, and signs of intervals

Hope this helps

The area of a circle is 25pi m squared what is the circumference

IceJOKER [234]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
A=25\pi 
\end{cases}\implies 25\pi =\pi r^2\implies \cfrac{25\pi }{\pi }=r^2
\\\\\\
25=r^2\implies \sqrt{25}=r\implies 5=\boxed{r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad C=2\pi\left( \boxed{5} \right)\implies C=10\pi$

5. What is the y-intercept of the line of best fit?

Verizon [17]

6. The y-intercept is 8

7. the slope is -1/2

8. Equation of line is: $y = -\frac{1}{2}x+8$

Step-by-step explanation:

Let us define y-intercept first

The y-intercept of the line is where the line intersects the y-axis.

5. What is the y-intercept of the line of best fit?

The given line on graph intersects the y-axis on 8 so the y intercept of the line of best fit is 8

6. What is the slope of the line of best fit for this scatter plot?

The slope can be calculated by locating two points on line.

In the given line, we can easily observe two points

(2,7) and (4,6)

The slope is calculated by the formula

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

Here (x1, y1) are the coordinates of first point on line and (x2,y2) are the coordinated of second point on line

So, putting the values

$m=\frac{6-7}{4-2}\\=\frac{-1}{2}\\=-\frac{1}{2}$

7. What is the equation of the line of best fit?

The slope intercept form of any line is given by:

$y=mx+b$

where m is slope and b is y-intercept of the line

As we already know

m = -1/2 and y-intercept is 8

Putting the values in the equation

$y = -\frac{1}{2}x+8$
