A. what is P(0)= I got 10

B. What does the answer from part A tell us about the trout population?

C. How many trout were in the lake after 1 year?

D. How many trout were in the lake after 10 years?

E. lim t→∞P(t)= I got 740

F. What does the answer from part E tell us about the trout population?

Answer:

u ≥ 2

Step-by-step explanation:

2u-5>7 :

Add 5 to both sides:

2u = 7 + 5

2u > 12

Divide by 2:

u > 6

-3u ≤ -6

Multiply both sides by -1, inequality reverses
-3u(-1) ≥ -6(-1)

3u ≥ 6

Divide by 3:

u ≥ 2

Since  u > 6  is a subset of u ≥ 2, the interval for both inequalities is

u ≥ 2

The error in River's analysis is that it is known if LM and MJ are perpendicular to KL and KJ.

What is error analysis?

Error analysis is a technique used to track out errors in learner language, ascertain whether they are systematic, and (if possible) provide an explanation for why they occurred.

It is given that -

Line segment KM is the bisector of ∠LKJ.

Also, line segment LM = MJ.

According to the angle bisector theorem if a line is a bisector of an angle then the corresponding sides of the angle should be perpendicular to the third side which is getting bisected.

Although it is given that  LM = MJ, but it is not known that if LM and MJ are   perpendicular to the sides of ∠LKJ.

Therefore, River cannot conclude that KM is the bisector of ∠LKJ.

Step-by-step explanation:

Cross multiply to solve for "a":

6 * a = 8 * 8

Simplify the right side:

6 * a = 64

Divide both sides by 6 to isolate "a":

a = 64 / 6

Simplify:

a = 10.67

Answer:

A. 12 cm, 5 cm, 17 cm

Step-by-step explanation:

For any three given lengths to be the sides of a triangle, they must satisfy the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides must be greater than the length of the third side.

Let's check each of the options:

A. 12 cm, 5 cm, 17 cm: 5 + 12 = 17, which is greater than 17, so this is a valid triangle.

B. 10 cm, 15 cm, 24 cm: 10 + 15 = 25, which is greater than 24, so this is a valid triangle.

C. 9 cm, 22 cm, 11 cm: 9 + 11 = 20, which is not greater than 22, so this is not a valid triangle.

D. 21 cm, 7 cm, 6 cm: 7 + 6 = 13, which is not greater than 21, so this is not a valid triangle.

Therefore, the three lengths that could be the sides of a triangle are A (12 cm, 5 cm, 17 cm) and B (10 cm, 15 cm, 24 cm).

Answer:

Expression for number of girls:

2b + 15

Equation for number of boys and girls:

b + (2b + 15) = 84

Number of boys

23

Number of girls

61

Step-by-step explanation:

b = number of boys

g = number of girls

b + g = 84

g = 2b+15

b + (2b + 15) = 84

3b + 15 = 84

3b = 69

b = 23

b + g = 84

23 + g = 84

g = 61

The function that is represented by the graph is y = ∛(x + 3) + 3.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The general form of a cube root function is -

y = a∛(x - h) + k and the parent graph is y = ∛x.

So the parent function is found.

The coordinate point for the parent function is -

(-1,-1) , (0,0) and (1,1).

In the graph it can be seen that the coordinate points are -

(-4,2), (-3,3) and (-2,4)

So the graph is first moved 3 units up and then moved three units left.

So, the coordinated become - (x + (-3) , y + 3)

So, the function that represents the graph is -

y = ∛(x + 3) + 3

Therefore, the function is y = ∛(x + 3) + 3.

Answer: no solution

Step-by-step explanation:

The point (1, 1/2) lie on the equation  y(x² + 1) = 1.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x, y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

Given, A function y(x² + 1) = 1.

y = 1/(x² + 1).

When x = 1, y = 1/2.

When x = - 1, y = 1/2.

So, The points that lie on the equation y(x² + 1) = 1 is (1, 1/2).

The surface area of the sphere is 1519.8 yd².

Three-dimensional shapes or solids are the names given to 3D shapes in geometry. Three separate dimensions, such as length, width, and height, are used to describe 3D shapes. The lack of thickness or depth in 2D shapes is the only distinction between them and 3D ones.

Given a sphere

diameter = 22 yards

radius = d/2 = 22/2

radius = 11 yards

the surface area of the sphere = 4πr²

Answer: x = 14; y = 74; Isosceles and Acute

Step-by-step explanation: 3(x+7) = 3x + 21

Isosceles triangles have congruent base angles making 63 = 3x +21

Solve for x.

All angles of a triangle add up to 180 making y = 180 - 63 - 63.

Isosceles because two sides are congruent. And acute because all angles are under 90.

The equation representing the total cost is 15x + 750 and the total cost of restringing 32 lacrosse sticks would be $1230.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let, The number of lacrosse sticks be 'x' and the total cost is C(x).

Therefore, The equation representing the context is,

C(x) = 25x + 750.

The total cost of restringing 32 lacrosse sticks would be,

C(32) = 15×32 + 750.

C(32) = 480 + 750.

The explicit rule for the nth term of the geometric sequence: 3, 18, 108, 648, 3,888, … is aₙ = 3( 6ⁿ⁻¹ )

The geometric sequence is expressed as aₙ = a₁ × rⁿ⁻¹

Given the set of numbers in the question;

3, 18, 108, 648, 3,888, …

The first term a₁ = 3

Next, we determine the common ratio r.

Divide a term by the previous term gives the common ratio.

Common ratio r = 18/3

Common ratio r = 6

Now, plug in the values of first and common ratio into the above formula to determine the nth term.

aₙ = a₁ × rⁿ⁻¹

aₙ = 3 × 6ⁿ⁻¹

aₙ = 3( 6ⁿ⁻¹ )

Therefore, the nth term of the sequence is aₙ = 3( 6ⁿ⁻¹ ).

Option D) aₙ = 3( 6ⁿ⁻¹ ) is the correct answer.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for this problem are given as follows:

[tex]\mu = 1100, \sigma = 70, s = \frac{70}{\sqrt{n}}[/tex]

The p-value of Z when X = 1120 is of 0.92, hence Z = 1.405, and the sample size is obtained as follows:
