Using this model, the predicted number of owls in year 8 is about - 11. Does
this prediction make sense? Why or why not?

Answer 1

Answer:

No, it doesn't make sense, as we cannot have a negative population of owls.

Step-by-step explanation:

Obtaining a the quadratic model :

y = -1,34x2 - 10,75x - 11.3 ; by fitting the data above ;

To obtain the number of owls after 8 years, we have ;

y = -1,34x2 + 10,75x - 11.3

put x = 8 in the equation

y = -1,34(8)^2 + 10.75(8) - 11.3

y = - 85.76 + 86 - 11.3

y = - 11.06

y = - 11

This figure dies not make sense, as we cannot have a negative population of a certain specie such as owls at any given time.

Answer 2

Answer:

No, because you can't have a negative number of owls.

Which two steps could be taken to simplify the expression y/3 + 2 = 11?

Answers

Answer:

y = 27

Step-by-step explanation:

y/3 + 2 = 11

First subtract 2 from each side

y/3 + 2-2 = 11-2

y/3  = 9

Then multiply each side by 3

y/3 *3 = 9*3

y = 27

Answer:

Answer is below :)

Step-by-step explanation:

y/3 + 2 = 11 is the Expression

Only two steps:  

step 1 = subtract 2 from both the sides

y/3 = 9

Step 2 = multiply 3 from both sides

y = 27

In the graph above, what's the distance between (–1, –4) and (–1, 5)?

Answers

9514 1404 393

Answer:

  9 units

Step-by-step explanation:

The graph shows a vertical line at x = -1, with points at y=-4 and y=5. The distance between the points is the difference of their y-coordinates:

  5 -(-4) = 5+4 = 9

You can count the grid squares between the points, if you like.

The distance between the points is 9 units.

Answers

Answer:

y  =  [tex]\frac{-8}{3}[/tex]x + [tex]\frac{62}{3}[/tex]

Step-by-step explanation:

Use slope formula.

then substitute slope for m in y = mx + b

pick a set of coordinates and substitute them in for x and y.

Solve for b

Answer:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (7,2) and (10,-6)

[tex]m=\frac{2-(-6)}{7-10}\\m=\frac{2+6}{7-10}\\m=\frac{8}{-3}[/tex]

Therefore, the slope of the line is [tex]-\frac{8}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{8}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{8}{3}x+b[/tex]

Plug in one of the given points and solve for b

[tex]2=-\frac{8}{3}(7)+b\\2=-\frac{56}{3}+b[/tex]

Add [tex]\frac{56}{3}[/tex] to both sides to isolate b

[tex]2+\frac{56}{3}=-\frac{56}{3}+b+\frac{56}{3}\\\frac{62}{3}=b[/tex]

Therefore, the y-intercept is [tex]\frac{62}{3}[/tex]. Plug this back into [tex]y=-\frac{8}{3}x+b[/tex]:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

I hope this helps!

Exponential decay function

Now, the general formula for exponential decay function is;

f(x) = abˣ

where b is the decay factor.

Now, the decay factor which we will call the base of the exponent must be greater than 1 .

Also, the exponent x must be negative to be called an exponential decay function.

Looking at the given options, only Option C meets the criteria for an exponential decay function.

The given options are;

A) f(x) = ³/₄(⁷/₄)ˣ

Answers

Answer:

Step-by-step explanation:

Y-intercept of line is 14

slope of line = (0 - 14)/(10 - 0) = -14/10 = -7/5

Required equation is y = -7/5 x + 14

Answer:

y=3x-4

Step-by-step explanation:

The slope-intercept form of the equation of a line is written in y=mx+b

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

So in that form

y=mx+b  becomes

y=3x-4 using your slope of 3 and y-intercept of -4
