One species of fish in a fishery had an initial population
of 255 fish and after 9 seasons, the population had grown to
480 fish. A second species that was being overfished started
with an initial population of 450 fish, and after the same 9
seasons, it had a new population of 90 fish. Assuming a
linear growth, write the equations for the population of
•each species. Graph your equations in the coordinate plane.
Find the point in the graph which represents when the two
populations will have the same number of fish. After how
many seasons will the second population be eliminated?

5 and 6 are NOT functions but 4 IS a function

Step-by-step explanation:

A number cannot repeat in the x axis

Step-by-step explanation:

The following are quadratic equations:

x² + 3x - 5 = 0,

x² - x = 3x + 7,

7x² + 14x = 0.

Answer:

1. X,-1

2. X≥2

Step-by-step explanation:

This is right

Answer:

15 meters

Step-by-step explanation:

Because angle BFD and angle DFC are supplementary (they form a 180 degree angle, as you can see from the fact that they both form a straight line) and angle BFD is 90 degrees, angle DFC must also be 90 degrees. Since it is 90 degrees, you can use the Pythagorean theorem to solve for DF as a part of triangle DFC=> 8^2(x^2)=17^2.

=>64(x^2)=289

subtract 64 from both sides=> x^2=225

take the square root of both sides=> x=15

Since triangles BED and BFD are equal by way of angle-side-angle, we know that all of their corresponding sides and angles are equal, and therefore, DF=DE, so DE=15 meters

Step-by-step explanation:

The attached figure shows two triangles AOB and MON.

In triangles AOB and MON,

AB = MN (Given )

∠AOB = ∠MON (vertically opposite angles)

∠O = ∠O (common)

∴ ΔAOB ≅ Δ MON (ASA)

Angle-side-angle is the postulate that can be used to prove that two triangles are congruent.

a. you would do 1346/1500 to get 0.8973333333333. i you want to check that you can do 1346/0.8973333333333 and you would get 1500. I'm just going to round 0.8973333333333 down to 0.897. So for town B you would also do 1546/1800 which brings you to 0.858889  you can again do 1546/0.858889 but i found that 0.8588888888 gives you the most accurate answer. so rounding that down to 0.859

b. you can see that 0.897 is a larger percent that 0.859 so town a had a larger increase than b

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

Answer:

The number, x = { -5 < x < 14}

This means x is any integer between -5 and 14

Step-by-step explanation:

From the statement, let the number be x

3 + x = y; y = { -2 < y < 17}

This means that y is any integer between -2 and 17

Therefore, x = y - 3

Subtract 3 from the limits of y

i.e. -2 - 3 = -5 and 17 - 3 = 14

Hence, x = { -5 < x < 14}

Answer:

1. isosceles

2. Right

Step-by-step explanation:

Here, we want to give the kind of triangle in each of the diagrams

1. From what we can see, we have two sides equal to each other using the given markings. More specifically, the base sides are equal and that makes the triangle an isosceles triangle

2. From what we can see here, we have an angle of 90 degrees on one of the sides of the triangle. In other words, we have a right angle on one of the sides.

This makes the triangle, a right triangle

Answer:

C

Step-by-step explanation:

It is C. because it is the formula for Pythagorean theorem.

Answer:

x = - 3, y = 6

Step-by-step explanation:

For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.

Given

- 3 + yi = x + 6i , then

x = - 3 and y = 6

Answer:

38 square meters

Step-by-step explanation:

Given:

A(w)=4w²+34w

The function represent the area of a metal frame being built by a construction company

What is the area of the frame in square meters when the width equals 1 meter?

Find A(w) when w = 1 meter

A(w)=4w²+34w

A(1) = 4(1)² + 34(1)

= 4 + 34

= 38 square meters

A(1) = 38 square meters

Answer:

3a. 0.415

b. 18.75

Step-by-step explanation:

3a. 2.49/6

=0.415

b. 150/8

=18.75

Answer:

Gather your like terms together

Step-by-step explanation:

(x+4x+x) = 6x

(-10-10+2) = -18

6x -18 = 180 (the sum of triangle angles)

Add 18 to both sides

6x = 198

divide 198 by 6

x = 33
