The point (4,9) corresponds to the number of birds in the population when the biologists discovered it.
What is a function?The function is a type of relation, or rule, that maps one input to a specific single output.
Biologists discovered an invasive bird species on an island.
The function fff models the population size (in hundreds of birds) for this species as a function of time (in months) after being discovered.
The population drops after 4 months making that the maximum the population of the fish.
The answer will be (4,9) the vertex of the parabola which is basically the top of the peak.

[tex]x^{2} +9y^{2} =1[/tex] is an ellipse. The line y=mx+2 is tangent to the ellipse. Determine the value of ([tex]m^{2}[/tex]). Express your answer as an integer or as a common or improper fraction.
9514 1404 393
Answer:
m^2 = 35/9
Step-by-step explanation:
The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.
x^2 +9(mx +2)^2 = 1
x^2 +9(m^2x^2 +4mx +4) = 1
(9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms
__
Then the discriminant is ...
(36m)^2 -4(9m^2 +1)(35)
We want it to be zero, so we have ...
1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses
36m^2 = 140 . . . . . . . . . . . . . . . add 140
m^2 = 140/36 . . . . . . . . . . . . divide by 36
m^2 = 35/9

Step-by-step explanation:
1. En la granja del tío de Carlos se han acomodado 525 huevos en cartones pequeños y grandes a razón de 3 2 . Si en los cartones pequeños se acomodaron 15 huevos y en los grandes 30, ¿cuántos cartones pequeños y cuántos grandes se utilizaron? donde dice 3 tendria que ir como una fraccion 3 y abajo del 3 el 2
Answer:
Small cartons used , x = 15
Large cartons used , y = 10
Step-by-step explanation:
Given - 1. On Carlos's uncle's farm, 525 eggs have been accommodated in small and large cartons at a rate of 3/2
2. If 15 eggs were accommodated in the small cartons and 30 in the large cartons.
To find - How many small cartons and how many large cartons were used?
Solution -
Let
Small cartons used = x
Large cartons used = y
Now,
Given that,
Small and large cartons at a rate of 3/2
⇒[tex]\frac{x}{y} = \frac{3}{2}[/tex]
⇒x = [tex]\frac{3}{2} y[/tex] ............(1)
Now,
Given that,
Total eggs accommodated = 525
Also,
15 eggs were accommodated in the small cartons and 30 in the large cartons.
⇒15 x + 30 y = 525
Now,
put the value of x in the above equation, we get
15([tex]\frac{3}{2} y[/tex] ) + 30 y = 525
⇒[tex]\frac{45 + 60}{2} y = 525[/tex]
⇒[tex]\frac{105}{2} y = 525[/tex]
⇒y = [tex]525*\frac{2}{105}[/tex]
⇒y = 5(2) = 10
⇒y = 10
Now,
Put the value of y, we get
x = [tex]\frac{3}{2} y[/tex] = [tex]\frac{3}{2}(10)[/tex] = 3(5) = 15
∴ we get
x = 15
y = 10
So,
Small cartons used , x = 15
Large cartons used , y = 10

6a+4b−66, a, plus, 4, b, minus, 6 when a=1a=1a, equals, 1 and b=3b=3b, equals, 3.
Answer:
The answer is 12.
Step-by-step explanation:
We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3
Put a = 1 and b = 3 in the above expression.
6a+4b−6 = 6(1) +4(3) -6
= 6+12-6
= 12
So, the value of the given expression is equal to 12.
The area of a rectangular garden is 8330 m².
If the length of the garden is 98 m, what is its width?
9514 1404 393
Answer:
85 m
Step-by-step explanation:
The area is the product of length and width. This can be used to find the width.
A = LW
8330 m² = (98 m)W . . . . . . . . . . . fill in the given values
8330 m²/(98 m) = W = 85 m . . . . divide by the coefficient of W
The width of the garden is 85 meters.

use the geometric mean theorems to find AC and BD. BA=20 BC=15
Step-by-step explanation:
first, you use the pythagorean theorem to find the missing side of the original and big triangle.
[tex]20 {}^{2} + 15 {}^{2} [/tex]
next, you simplify these into actual numbers
[tex]400 + 225[/tex]
after, you add these numbers together and find the square root.
[tex]\sqrt{625} = 25[/tex]
you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.
The requried Measure of the BD and AC in the given question is 17.32 and 25 respectively.
What is the geometric mean theorem?The geometric mean theorem for a right triangle states that the length of the altitude (height) to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.
Here,
From the triangle, following the Geometric mean theorem,
BD = √[AB×BC]
BD = √[20×15]
BD = √17.32
Now,
Applying the Pythagorean theorem to find AC,
AC = √15² + 20²
AC = 25
Thus, the requried Measure of the BD AC in the given question is 17.32 and 25 respectively.

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
- 6 > 4x - 2 ( add 2 to both sides )
- 4 > 4x ( divide both sides by 4 )
