What are the roots of the polynomial equation? –12, 12 –4, 3 –3, 4 –1, 1

andrezito [222]

For this case what you should see is where both functions intersect.
We have that in this case, the functions intersect in:
x = -3
x = 4
Therefore the roots of the polynomial are:
x = -3
x = 4
Answer:
-3, 4 (option 3)

Really need help I don't understand

Mrrafil [7]

we know the circumference shown for that picture is π miles, what would it be for the diameter? namely how long is the diameter of that circle whose circumference is π miles?

$\bf \textit{circumference of a circle}\\\\ C=\pi d~~ \begin{cases} d=diameter\\ \cline{1-1} C=\pi \end{cases}\implies \pi =\pi d\implies \cfrac{~~\begin{matrix} \pi \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} \pi \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}=d\implies 1=d$

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of va

kow [346]

Answer:

$16\ acres$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

substitute the values of x and y

$k=\frac{551,520}{20}=\$27,576\ per\ acre$

The linear equation is equal to

$y=27,576x$

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

I need help with this i need u to help ne wit the number line

kupik [55]

Word the problem so it helps you with the double number line like this:
Question:
If 1/6 mile of a fence is completed each hour how long will it be in 4 hours?

Then use the double line:

1/6-----miles(1/6*4)------X Length X=1/6*4
I X= 1/6*4/1
I X= 4/6 ≈2/3 miles
1-------hours--------------4 Time
Here is a video that might help with your homework a lot :) Good luck

WUTS THE ANSWER IM SO LOST I NEED HELP!!! :(

Alex_Xolod [135]

1/6 = 0.16 acres in 8 minutes.

--

0.16 ÷ 8 = 0.02 acres mowed in 1 minute.

--

(60 minutes in an hour)

0.02 x 60 = 1.2 acres mowed in an hour.

--

1.2 is equal to 1 1/5, and jami needs to mow 1 1/2 acres. so no, jami cannot mow 1 1/2 acres in an hour.
