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

Answer:
The measure of angle D and A must be equal.
Step-by-step explanation:
ASA means angle-side-angle. So you must have two angles and the side between them be congruent to the other triangle. We already know Angle C and F are congruent and Side lengths AC and FD are congruent. So we just need the angles on the other side of the side lengths.

Which two steps could be taken to simplify the expression y/3 + 2 = 11?
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)?
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.
Find the equation for the line that passes through the points ( 7 , 2 ) and ( 10 , − 6 ) . Give your answer in slope intercept form
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!

What is the slope of the line?
Pls help! I’ll mark the brainliest
Answer:
m = -3
Step-by-step explanation:
Two poin on this line are (-2, 3) and (0, -3). Both points are formed where grid lines meet precisely.
The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6. Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

C: f(x) = ³/₂(⁸/₇)⁻ˣ
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
B) f(x) = ²/₃(⁴/₅)⁻ˣ

Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.
Answer:
96.25
Step-by-step explanation:
A ztable gives us values for P(X<x) and we're looking for P(X>x) so by the rule a symmetry we must make the value negative
Go to a ztable and find the value closest to .6 (I get .25), make this negative and let's set up our equation
-.25=(x-100)/15
solve for x
-3.75=x-100
x=96.25

a stick is x meters long. a string is 4 times as long as the stick.
Express the length of the string in terms of x
Answer:
Step-by-step explanation:
Length of stick = x meters
Length of string = 4 * length of stick
= 4 * x
= 4x
Answer:

y-intercept= (0, -4)
slope = 3
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
