The initial bacterium count in a culture is 500. A biologist later makes a sample count ofbacteria in the culture and finds that the relative rate of growth is 40% per hour.(a)Find a function that models the number of bacteria after t hours.(b)What is the estimated count after 10 hours?(c)When will the bacteria count reach 80,000?(d)Sketch the graph of the function . n(t)

Answers

Answer 1

a) The function is P = 500e^0.4t

b) The count after 10 hours is 27299

c) it would reach 80000 in 13 hours

What is the function?

We know that at this time we are dealing with the population of the bacteria and we have to invoke the exponential growth ideology and we would have;

P = Poe^rt

P = population at time t

Po = Initial population

r = Population growth rate
t = Time taken

Then we have;

P = 500e^0.4t

After ten hours;

P= 500e^0.4 * 10

P = 27299

The count would reach 80000 when;

80000 = 500e^0.4 t

80000/500 = e^0.4 t

160 = e^0.4 t

ln160 = e^0.4 t

ln160 = 0.4t

t = ln160/0.4

t = 13 hours

a destroyer simultaneously fires two shells with different initial speeds at two different enemy ships. the shells follow the parabolic trajectories shown.

Answers

1. At 4.142s the first shell will hit the first enemy ship.

2. At 3.536s the second shell will hit the second enemy ship.

3. The two shells will be 677.1 meters apart when they hit their respective targets.

To solve this problem, we can use the equations for the horizontal and vertical motion of a projectile.

The horizontal velocity of a projectile can be found using the equation: [tex]v_x = v_0 * cos\theta[/tex] where,

[tex]v_0[/tex] is the initial velocity[tex]v_x[/tex] is the horizontal velocity[tex]\theta[/tex] is the angle at which the projectile is fired.

The vertical velocity of a projectile can be found using the equation:

[tex]v_y = v_0 * sin\theta[/tex]

The horizontal displacement of a projectile can be found using the equation:

[tex]x = v_0 * cos\theta * t[/tex]

The vertical displacement of a projectile can be found using the equation:

[tex]y = v_0 * sin\theta * t - (1/2)gt^2[/tex] where,

t is the time g is the acceleration due to gravity (approximately 9.8 m/s^2) x and y are the horizontal and vertical displacements.

1. To find the time that the first shell will hit the first enemy ship, we can use the equation for the horizontal displacement:

[tex]t = x / (v_0 * cos\theta)[/tex]

t = 2000m / (800m/s * cos(45))

= 4.142s

2. To find the time that the second shell will hit the second enemy ship, we can use the equation for the horizontal displacement:

[tex]t = x / (v_0 * cos\theta)[/tex]

t = 2000m / (1000m/s * cos(60))

= 3.536s

3. To find the distance between the two shells when they hit their respective targets, we can use the equation for the horizontal displacement:

[tex]x_1 = v_0 * cos\theta * t \\x_2 = v_0 * cos\theta * t[/tex]

x1 = 800m/s * cos(45) * 4.142s

= 2858.9m

x2 = 1000m/s * cos(60) * 3.536s

= 3536m

x2 - x1 = 3536m - 2858.9m

= 677.1m

So the two shells will be 677.1 meters apart when they hit their respective targets.

Answers

petroleum formation happens When dinosaurs became extinct 65 million years ago, their bodies decayed to become petroleum.

What is decomposition?

Dead creatures are broken down into their basic chemicals through the process of decomposition by bacteria and fungus. The cycle can be completed by plants absorbing and using these substances once again. Because of how they decompose dead organic stuff, decomposing bacteria and fungus are referred to be saprophytic.

Oil and gas are created from organic material that has been decomposed and altered over millions of years, mostly as sediments on the seafloor.

Fuels known as petroleum products are created from crude oil and the hydrocarbons found in natural gas. Coal, natural gas, and biomass can also be used to make petroleum products.

Plant and animal remains are used to create petroleum. Animals and plants that pass away sink and land on the seafloor. These extinct animals and plants decayed millions of years ago and mingled with sand and silt.

Therefore, we can say Petroleum is produced. Dinosaurs became extinct 65 million years ago, and when their corpses decomposed, petroleum was created. Petroleum doesn't form until hundreds of millions of years. Oil was created in chilly climates.

Y=-2x-4 y=1/2x +6 what is the solution of the system of equation

Answers

Answer:

Step-by-step explanation:

Answer is ( -4, 4 )

Step by step

y = -2x -4 ➡️equation 1
y= 1/2x + 6 ➡️equation 2

Using substitution method, substitute the value of y from equation 1 in for y in equation 2 and solve for x

-2x -4 = 1/2x + 6
Subtract 1/2x from both sides to combine x

-2x -1/2x -4 = 1/2x - 1/2x + 6
Simplify

-2 1/2x -4 = 6
Add 4 to both sides to combine constants

-2 1/2x -4 +4 = 6 + 4
Simplify

-2 1/2x = 10
Divide both sides by -2 1/2 to solve for x

-2 1/2 / -2 1/2 x = 10 / -2 1/2

x = -4

Now substitute -4 for x in the first equation

y = -2(-4) -4
y = 8 - 4
y = 4

So your solution is ( -4, 4)

Answer:

There are several lines of evidence that scientists use to determine the relative age of the Earth and its various features. These include:

Stratigraphy: This refers to the study of rock layers and the sequence in which they were formed. Scientists use stratigraphy to determine the relative ages of different rock layers and the fossils they contain. The principle of superposition states that in any undisturbed sequence of rocks, the oldest rock layers will be at the bottom and the youngest will be at the top.

Fossil record: Fossils are the remains of plants and animals that lived in the past. By studying the fossils in rock layers, scientists can determine the relative ages of different rock formations and the organisms that lived in them. Fossils of extinct species found in lower rock layers are older than those found in higher rock layers.

Radiometric dating: This is a method that uses the decay of radioactive isotopes in minerals to determine the absolute age of rocks and minerals. Scientists can use radiometric dating to determine the age of a rock or mineral, and by comparing the ages of different rocks and minerals, they can determine the relative ages of different rock formations and the Earth's surface features.

using linear stability analysis, classify the fixed points of the gompertz model of tumor growth n an

Answers

The Gompertz model of tumor growth is a mathematical model that describes the growth of a tumor over time. It is characterized by two parameters, the intrinsic growth rate (r) and the carrying capacity (K), and is described by the following differential equation:


dn/dt = rn(1 - n/K).where n is the size of the tumor and t is time.

To classify the fixed points of the Gompertz model of tumor growth using linear stability analysis, we first need to find the fixed points by setting dn/dt = 0 and solving for n. The fixed points are the values of n that make the tumor size constant. In this case, the fixed point is n* = K.

Next, we need to linearize the system around the fixed point by using the Jacobian matrix. The Jacobian matrix for the Gompertz model is:
J = [dr/dn, d(rn(1-n/K))/dn]
[-rn(1-n/K)/K, rn(1-n/K)+(r*n/K^2)]

In the Gompertz model, the fixed point is n* = K, and the eigenvalues are -r and r/K, which are both negative. This means that the fixed point is stable, and the tumor size will converge to the carrying capacity K if perturbed.

Substances and their modifications, equations and surrounding structures, objects and their placements, and locations where they can be found are all included in the study of mathematics. The relationship between a group of inputs, each of which produces related output, is referred to as a "function." A function is a relationship between both inputs and outputs where each input produces a single, unique result. Every function has a domain and a codomain, often known as a scope. F is typically used to denote functions (x). An x is the input. Based on the following criteria, there are four primary categories of functions that are available: on functions, yet another functions, many-to-one functions, within functions, and on functions.

given

The task's purpose makes it clear that the point on the graph of y = f(x) that cannot be found.

The definition of a function, f(x), states that it is a relation that assigns just one value of y to each value of x.

As a result, the statement above suggests that the x-value -7 can only be given one y-value, which is 0, if the point (-7, 0) is on the graph of the function y = f(x).

In the end, the following is an illustration of a point that cannot appear on the graph of y = f(x): (-7, 1).

There are three terms in the polynomial so each term of the polynomial numerator is separately divided by the same monomial denominator.

What is a monomial ?

Monomial is polynomial in which it has only one term.

Given ,

To find Which property would you use to simplify this monomial division problem.

For example :

4a^3 - 10a^2 + 5a  /  2a

Now the polynomials ( 4a^3 - 10a^2 + 5a) is written as numerator and the monomial (2a) is written as denominator

Therefore,

we get 4a^3 - 10a^2 + 5a  /  2a .

Now we observe that there are three terms in the polynomial so each term of the polynomial numerator is separately divided by the same monomial denominator.

4a^3 / 2a  -  10a^2 / 2a  + 5a/2a

Therefore, there are three terms in the polynomial so each term of the polynomial numerator is separately divided by the same monomial denominator.

These mathematical operations can be solved in the given manners.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given some fractions to solve for understanding, I will solve two questions with the same denominator and two with different denominators one with a whole number and one fraction.

6/10 ÷ 4/10

Since the base is the same

=> 6/4

=> 1.5

6/10 ÷ 2/5

We can write 2 /5 as 4/10 since their values are the same

=> 6/10 ÷4/10

=> 6/4

=> 1.5

1/4 ÷4/6

we can write 1/4 as 6/24 and 1/6 as 4/24 to make the denominator same.

=> 6/24/4/24

=> 4/4

=> 1.5

2/9 ÷ 5/6

We can write 2/9 as 4/18 and 5/6 as 15 / 18 to make the denominator the same

An open box is made from a 40-cm by 89-cm piece of tin by cutting a square from each corner and folding up the edges. The area of the resulting base is 2100cm^. What is the length of the sides of the square

Answers

Answer:

√365 cm

Step-by-step explanation:

We can begin by using the formulas for the area of a rectangle and a square to set up an equation. Let x be the length of the sides of the square that is cut out of each corner of the rectangle.

The area of the original rectangle is 40cm * 89cm = 3560cm^2.

The area of the square that is cut out of each corner is x^2.

The area of the remaining base of the box is 2100cm^2.

So, we have:

3560cm^2 - 4x^2 = 2100cm^2

Solving for x, we get:

x = √(3560cm^2 - 2100cm^2)/4 = √(1460cm^2)/4 =√365cm

So the length of the sides of the square is √365 cm

A researcher reports that a sample of workers with high-stress careers slept significantly less than workers in the general
population, t(49)-2.5, p<.05.
• Compute eta-squared for this one-sample t test.
• Classification of effect.
(Privitera, 2019, p. 233, Learning check 3, #4, modified)

Answers

Eta-squared is a small effect size that means the difference between the sample of workers with high-stress careers and the general population is statistically significant, but not clinically meaningful.

What is eta-squared?

Eta-squared is a proportion of variation explained by a statistical model or an experimental design. It is used in ANOVA and other types of regression analysis to determine how much of a dependent variable's variation may be attributable to the independent variable (s).

In the given question, Eta-squared is computed by taking the square of the t-value (2.5 in this example) and dividing it by the sum of the t-value and degrees of freedom squares (49 in this case). The result is an eta-squared value of 0.050.

This eta-squared value corresponds to a modest impact size. This suggests that the gap between the sample of high-stress employees and the overall population is minor but statistically significant. In other words, high-stress professionals may sleep less than the general population, but the difference is not significant enough to be clinically significant.
