The populations of two cities after t years can be modeled by

Answers

Answer:

Step-by-step explanation:

Hello There!!

Given

Value of 't' = 4

To Find

Difference between the population of the two cities

Solution

[tex] \text{{Assuming the population of two cities as}} \: \text{c}_1 \text{ and} \: \text{c}_2[/tex]

[tex] \text{ In Case of }\text{c}_1[/tex]

[tex]\text{c}_1 = -150\text{t} + 50,000 \\ \implies \text{c}_1 = - 150 \times 4 + 50,000 \\ \implies \text{c}_1 = - 600 + 50,000 \\ \implies \text{c}_1 = 49,400[/tex]

[tex] \text{ In Case of }\text{c}_2[/tex]

[tex]\text{c}_2 = 50\text{t} + 75,000 \\ \implies \text{c}_2 = 50\times 4 + 75,000 \\\implies \text{c}_2 = 200+ 75,000 \\ \implies \text{c}_2 = 75,200[/tex]

Now, We need to find the difference in their population

[tex]\text{c}_2 - \text{c}_1 \\ = 75,200 - 49,400 \\ = 25,800[/tex]

[tex]\therefore \text{Difference between their Population=} \red{25,800}[/tex]

Jenna wants to wrap a shipping box shaped like a rectangular prism. The box is 20 inches tall and has a square base with sides that each measure 3 inches. How much paper will she​ use?

Answers

Answer:

23 inches

Step-by-step explanation:

258in squared of wrapping paper.

Explanation:

For this question, we are trying to find the surface area of the rectangular prism, not the area inside the rectangular prism because we are wrapping the box up.

So, If we break up the rectangular prism, we will get 4 rectangles that are 20 inches by 3 inches, and 2 squares (the base and the top) that are 3 inches by 3 inches.

What we have to do know is find the area of all these pieces, then add them together.

So for the 4 rectangles:

A = l x w
= 20 inches x 3 inches
= 60 inches

Since there’s 4 rectangles we do:
60 x 4 = 240 inches

For the 2 Squares:

A = l x w
= 3 inches x 3 inches
= 9 inches

since there’s 2 squares we do:
9 x 2 = 18 inches



Then we can add these totals up for the total surface area:

240 + 18 = 258 inches squared

ok so this is not for a test but solve this
8,827+8,729= A
A=....?

a is answer ok.?

A 12ft. ladder is leaned against a wall. If the base of the ladder is 5ft. from the wall, how high up on the wall does the ladder reach?​

Answers

Answer:

use Pythagoras theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ \\ a = 5 \\ b = (required \: lenth) \\ c = 12 \\ \\ { {5}^{2} } + {b}^{2} = {12}^{2} \\ {b}^{2} = {12}^{2} - {5}^{2} \\ b = \sqrt{119} \\ b = 10.90871211[/tex]

Pythagorean Theorem

x^2 + 5^2 = 12^2

x^2 +25 = 144

x^2 = 119

x = √199 or 10.9087121146

an antigen is  toxic foreign substance, that induces an immune reaction in the body.

an antibody is a blood protein that is made in retort to the counteracting of a certain antigen.

apoptosis is the death of cells that occur normally and control part of a specific organisims growth.

an autoimmune disease is a condition in which your immune system mistakenly attack your body.

a b-cell is a type of lymphocyte that is responisble for the autoimmunity component in the adaptive immue system.

a t-cell is part of the immue system tht develop from types of stem cells in the bone marrow.

a helper is a type of white blood cells that serves as a specific and important key of immune functions.

a killer is an innate immune cell that shows a strong cytolyic function against physiologically stressed cells such as: tumor cells, and virus infected cells.

a suppressor is a lymphocyte that can suppress the antibody production by other lymphoid cells.

Antigen - a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies

Antibody - a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.

Apoptosis - the death of cells which occurs as a normal and controlled part of an organism's growth or development.

Autoimmune disease - Autoimmune disease happens when the body's natural defense system can't tell the difference between your own cells and foreign cells, causing the body to mistakenly attack normal cells. There are more than 80 types of autoimmune diseases that affect a wide range of body parts.

B-cell - B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system.

T-cells - T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.


Helper - A type of immune cell that stimulates killer T cells, macrophages, and B cells to make immune responses. A helper T cell is a type of white blood cell and a type of lymphocyte. Also called CD4-positive T lymphocyte.

Killer - A type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus. A natural killer cell is a type of white blood cell. Also called NK cell and NK-LGL.

Supresor - A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function.

Memory - Memory is the ability of the brain to encode, store and retrieve information when required.

Leukocyte - A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.

Erythrocyte - A blood cell with hemoglobin-rich cytoplasm and whose main function is to transport respiratory gases, chiefly oxygen

Lymphocyte - a form of small leucocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.

Lymph nodes - Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.

Macrophage - a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.

Mast cells - Mast cells are blood cells that are part of your immune system. They help you fight infections, but they are also involved in allergic reactions. Mast cells live longer than normal cells, and they grow in your bone marrow, your gastrointestinal tract, your skin, and your airways.

Pathogen - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.

Phagocyte - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.

To predict volcanic eruptions scientists may use a seismograph to detect small earthquakes out of the 169 active volcanoes in the U.S. about 130 are in Alaska. About how many active U.S. volcanoes are not is Alaska?

Answers

Answer:

39 active volcanoes.

Step-by-step explanation:

Subtract 169 (whole) from 130 (part). 9 - 0 = 9, 6 - 3 = 3, and 1 - 1 = 0. Therefore, 169 - 130 = 39

39 (169-130) - a simple subtraction

Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4 In other words, a change of 1 unit in x corresponds to a change of 0.4 units in y. Graph the line and write the equation of the line.

PLS HELP WILL GIVE BRANLIEST + 20 POINTS

Answers

So here the 'unit rate of change' means the slope. It's also referred to as 'rise over run'. A line can be expressed in the form y=mx+b, where m is the slope and b is the y intercept. So here, m is equal to 0.4 and the line is y=0.4x

Think of it this way: if you plug in 1 for x, you get 0.4 for y. So that matches what the problem was saying about a change of 1 unit in x means 0.4 units in y. To graph it, start at 0,0 and move 0.4 up in y direction (rise) and 1 to the right in the x direction (run). If you keep doing that and connect the points, that will be the line

The answer is y= 0.4x
Explain the answer
When x= 5 y=0.4 x 5=2 (5,-2) Tip equation of line is y=lax straight line must pass point (0,0)

Given that,

→ Diameter = 3 in

→ Radius (r) = 3/2 = 1.5 in

Formula we use,

→ Area of circle = πr²

Then the area of circle will be,

→ πr²

→ 3.14 × 1.5 × 1.5

→ 7.065

→ 7.07 in²

Hence, the solution is 7.07 in².
