Answer:

Function: A=1.5(1+0.114)^1000

Step-by-step explanation:

1.5 is the initial amount and 0.114 in the rate and the 1000 is the time

In carbon dating, the Carbon-14 concentration decays exponentially, and can be described by a formula involving its initial concentration and decay rate. To find a fossil's age with a concentration of 0.3 ppt, we use this decay formula, solve for t (time in millennia), and calculate the fossil's age.

To determine the Carbon-14 concentration as a function of time and the age of a fossil with a concentration of 0.3 ppt, we will use the formula of exponential decay based on the half-life concept in carbon dating.

The formula for the carbon-14 concentration as a function of time (t, in millennia) is:

C(t) = C_0 × (1 - 0.114)^t

Where:

To find the age of a fossil with a measured concentration of 0.3 ppt, we solve for t in the above equation with C(t) set to 0.3 ppt:

0.3 = 1.5 × (1 - 0.114)^t

Dividing both sides by 1.5 and taking the natural logarithm:

t = ln(0.3/1.5) / ln(1 - 0.114)

Solving this gives us the age of the fossil in millennia.

Answer:

$67.41

Step-by-step explanation:

We want to find out how much 30% off of $96.30 is. To do that, we need to first multiply $96.30 to find out how much 30% would be. Don't forget to change 30% into its decimal form (30% - > .3).

96.30 x .3 = 28.89

This means that Steve got $28.89 dollars removed from his final bill. To find the actual final bill, subtract 28.89 from 96.30.

96.30 - 28.89 = $67.41

Answer:

she can make 40 ounces of green paint

Step-by-step explanation:

20 ounces of yellow paint and 20 ounces of blue paint

The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.

Two or more expressions with an Equal sign is called as Equation.

An artist mixes yellow and blue paint to make the perfect shade of green. She uses 2 ounces of blue paint for every 7 ounces of yellow paint

We need to find the most green paint the artist can make if the mixing container only holds 40 ounces.

Amount of blue paint = 2 ounce

Amount of yellow paint = 7 ounce.

Paint the mixing container can hold = 40 ounce.

Most green paints she can make. This is a ratio question

Yellow green

7 = 2

14 =4

21 =6

28 = 8

35 = 10

Hence, The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.

MATH

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Answer:

The side of square A'B'C'D' is 16 inches

Step-by-step explanation:

Given

Length of Square ABCD = 4 inches

Dilated with a scale factor of 4

Required

Length of square A'B'C'D'

To dilate something means to enlarge or reduce the size of that thing, depending on the scale factor.

Consider the following conditions

Having mentioned the conditions of dilation, Here, the "thing being dilated" is a square (ABCD) on a scale factor of 4.

The scale factor is greater than 1; so, the new shape (A'B'C'D) will be bigger than the previous shape (ABCD)

Now, how is the new size calculated?

The new size is calculated by multiplying the length of the previous shape by its scale factor;

In other words,

New Length = Old Length * Scale Factor

Where

Old Length = Length of ABCD = 4 inches

Scale Factor = 4

By Substitution,

New Length = 4 inches * 4

New Length = 16 inches

Hence, the side of square A'B'C'D' is 16 inches

  Spreadsheet values

  Other values

Step-by-step explanation:

Labeling the columns of the spreadsheet A--F, and the rows 1--7, we want to find the values as follows.

a) The relationship between quantity, price, and revenue is ...

  total revenue = quantity × price

  price = (total revenue)/quantity

Then ...

__

b) The relationship between total cost and marginal cost is ...

  mc2 = (tc2 -tc1)/(q2 -q1)

  tc2 = (mc2)(q2 -q1) +tc1

Then ...

__

c) Marginal revenue is figured the same way as marginal cost.

  mr2 = (r2 -r1)/(q2 -q1)

Then ...

__

d) The quantity maximizing profit will be the quantity such that marginal revenue is equal to marginal cost. That is, marginal profit is zero. That quantity  is 35, where both marginal cost and marginal revenue are 7.

__

e) The price at a quantity of 35 is 13. This value is read from the given table.

__

f) The maximum profit is the difference between revenue and cost at the profit-maximizing quantity:

  maximum profit = 455 -227.5 = 227.5

The question refers to Total Cost (TC) and Marginal Cost (MC) in economics; where TC is the sum of all production costs and MC is the cost of producing one more unit of a good. To fill the table, calculate the difference in total cost for each increase in produced units, as this difference reflects the MC.

The question is referring to the concepts of Total Cost (TC) and Marginal Cost (MC) in economics. Total Cost is the complete expenditure made by a firm in the production process, including both fixed and variable costs. Marginal Cost, on the other hand, is the cost of producing one additional unit of a good. In the case of the Choco Lovers firm, it represents the cost of producing an extra box of chocolates.

To fill in the blanks in the table, the differences in total cost for each increase in the quantity of chocolate gift boxes produced should be calculated. This is because the MC at each level of output is the addition to total cost when one more box is produced. So, if total cost rises by $5 when output increases from 10 to 11 boxes, the MC of the 11th box is $5.

Radius=10cm

Diameter=20cm

Step-by-step explanation:

The Diameter of the cylinder is 20 centimeters.

It is given that the cylinder has a volume of 2,512 cubic cm and a height of 8 centimeters.

It is required to find the diameter of the cylinder.

It is defined as a three-dimensional space enclosed by an object or thing.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2h[/tex]

Where r is the radius of the cylinder and h is the height of the cylinder.

We have V = 2512 cubic centimeters and

               h = 8 centimeters

[tex]\rm 2512 =3.14\times r^2\times8[/tex]

[tex]\rm \frac{2512}{3.14\times8} = r^2[/tex]

[tex]\rm r^2 =100[/tex]

r = 10 centimeters

Diameter = 2r = 2×10 ⇒ 20 centimeters.

Thus, the Diameter of the cylinder is 20 centimeters.

Answer:

The arc is one-third of the circumference.

Step-by-step explanation:

The area of a circumference = 2πr

C = 2πr ... (1)

If an arc subtends a central angle measuring 2π/3 rad,

The length of the arc = rθ

Given θ = 2π/3

Length of the arc L = r(2π)/3

L = 2πr/3... (2)

L = 1/3(2πr)

Since C = 2πr

L = 1/3C

This shows that the arc is one-third of the circumference.

From the question, we have the following parameters that can be used in our computation:

The list of options

Analyzing each statement, we have

a. On a coordinate plane, an absolute value function opens down.

The absolute value function f(x)=∣x∣ does not have an inverse that is a function because it fails the horizontal line test.

Specifically, any horizontal line intersects the graph of the absolute value function at most twice.

So, its inverse is not a function.

b. On a coordinate plane, an exponential function increases from quadrant 2 into quadrant 1.

Exponential functions, such as

f(x) = eˣ or f(x) = abˣ, do have inverses that are functions.

They pass the horizontal line test, and their inverses are logarithmic functions.

c. On a coordinate plane, a cubic function has an x-intercept of (0, 0).

A cubic function, such as f(x) = x³, does have an inverse that is a function.

The cubic function has an x-intercept at (0, 0), and its inverse is a cubic root function.
