How is the data represented on a scatterplot that depicts an exponential model?

1 answer:

4 0

The choices can be found elsewhere and as follows:

a. points on a line
b. random points
c. points on a horizontal line 
d. points on a curvy line

I believe the correct answer is option D. The data represented on a scatterplot that depicts an exponential model would be points on a curvy line. Hope this answers the question. Have a nice day.

Factor completely, then place the answer in the proper location on the grid.

Tresset [83]

$\mathrm{Factor\:out\:common\:term\:}9 \ \textgreater \ 9\left(x^4-25y^8\right)$

$Factor \ \textgreater \ x^4-25y^8$

$\mathrm{Apply\:difference\:of\:squares\:rule:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)$
$x^2-5y^4=\left(x+\sqrt{5}y^2\right)\left(x-\sqrt{5}y^2\right)$

$x^2-5y^4 \ \textgreater \ \mathrm{Apply\:difference\:of\:squares\:rule:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)$
$x^2-5y^4=\left(x+\sqrt{5}y^2\right)\left(x-\sqrt{5}y^2\right)$

$\left(x^2+5y^4\right)\left(x+\sqrt{5}y^2\right)\left(x-\sqrt{5}y^2\right)$

$9\left(x^2+5y^4\right)\left(x+\sqrt{5}y^2\right)\left(x-\sqrt{5}y^2\right)$

Hope this helps!

Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of

Colt1911 [192]

Each equation is a line and therefore will intercept each other at a single point. These points converge where the two y values are the same as that will produce the same coordinate. Therefore, we find the place where the two y values are equal to each other by setting the equations equal to each other.

You are planning to plant a triangular garden in your backyard, as shown. You plan to put up a fence around the garden to keep o

drek231 [11]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete has the figure of the triangle is not given.

However, the following steps will guide you.

To solve this question;

you need the lengths of the threes sides of the triangular fields

Represent these lengths with a, b and c

Next;

Sum these lengths together;

This gives the required length of fencing

$Length = a + b + c$

Take for instance;

$a =4;\ b = 3;\ c = 5$

The required length of fence would be

$Length = 4 + 3 + 5$

$Length = 12\ units$

Apply these steps and you'll get your answer

Answer:

P = 250 +50t

Step-by-step explanation:

We are given two pairs of time and price:

(t, P) = (0, 250) and (5, 500)

We can put these into the 2-point form of the equation for a line:

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

P = (500 -250)/(5 -0)(t -0) +250

P = 250/5t +250

P = 50t +250 . . . . Madelyin's cost equation
