2. The amount of a radioactive element at time t is given by the formula A(t)= A0ekt, (1) where A(0)= A0 is the initial amount of the element and k < 0 is the constant of proportionality which satisfies the equation (instantaneous rate of change of A(t) at time t) = kA(t). Iodine–131 is a commonly used radioactive isotope used to help detect how well the thyroid is functioning. Suppose the decay of Iodine–131 follows the model given in Equation (1), and that the half–life of Iodine–131 is approximately 10 days. If 5 grams of Iodine– 131 is present initially, find a function which gives the amount of Iodine–131, A, in grams, t days later, and then after 20 days.
The function that gives the amount of Iodine-131, A, in grams, t days later is A(t) = 5(1/2)^(t/10), and the amount after 20 days is 5/4 grams.
To find the function that gives the amount of Iodine-131, A, in grams, t days later, we can use the given formula A(t) = A0e^(kt).
Given that the half-life of Iodine-131 is approximately 10 days, we know that after each 10-day period, the amount of Iodine-131 will be reduced by half. This information allows us to determine the value of k.
Let's substitute the initial values into the equation:
A(0) = A0 = 5 grams.
We know that after 10 days, the amount is reduced by half. Therefore:
A(10) = 5/2 grams.
Using these two points, we can solve for k:
5/2 = 5e^(10k).
Dividing both sides by 5, we get:
1/2 = e^(10k).
Take the natural logarithm (ln) of both sides:
ln(1/2) = 10k.
Now, solve for k:
k = ln(1/2) / 10.
Now that we have the value of k, we can use it to find the function for the amount of Iodine-131, A, in grams, t days later.
The function is:
A(t) = A0e^(kt).
Substituting the known values:
A(t) = 5e^((ln(1/2)/10)t).
Simplifying:
A(t) = 5(1/2)^(t/10).
To find the amount of Iodine-131 after 20 days, we substitute t = 20 into the equation:
A(20) = 5(1/2)^(20/10).
A(20) = 5(1/2)^2.
A(20) = 5(1/4).
A(20) = 5/4 grams.

help? A crayon is shaped like a triangular prism. The base of the crayon is shown. If the crayon is 90 millimeters long, how many cubic millimeters of wax is used to make a box of 8 crayons?
Answer:
Unknown but formula (Check step by step solution)
Step-by-step explanation:
Without the image of the base of the crayon, I cannot determine the exact dimensions of the triangular prism or calculate the volume of a single crayon. However, I can give you a general formula for calculating the volume of a triangular prism and use it to find the total volume of wax needed to make a box of 8 crayons.
The formula for the volume of a triangular prism is:
Volume = (1/2) x base x height x length
where base is the area of the base of the triangular prism, height is the height of the triangular prism, and length is the length of the triangular prism.
Assuming all the crayons in the box have the same dimensions, let's say the base of the triangular prism has a length of L and a width of W. We can calculate the area of the base of one crayon as:
Base area = (1/2) x L x W
Since the crayon is 90 millimeters long, its height is 90 millimeters. Therefore, the volume of one crayon is:
Volume of one crayon = (1/2) x L x W x 90
To find the total volume of wax used to make a box of 8 crayons, we can multiply the volume of one crayon by the number of crayons:
Total volume of wax = Volume of one crayon x 8
Total volume of wax = (1/2) x L x W x 90 x 8
Total volume of wax = 360 x L x W
Again, without knowing the exact dimensions of the triangular prism, I cannot calculate the total volume of wax used to make a box of 8 crayons. But you can use the formula above and substitute the values of L and W based on the dimensions of the base of the crayon to find the answer.
We sample bags of candy under the assumption that the average weight is 16oz. with a population standard deviation of 1.25oz. Let x represent the average weight of our sample of bags of candy. What is the probability the average weight of our sample is greater than 15.8oz if our sample size is 40 bags of candy?
The Probability that the average weight of our sample is greater than 15.8 oz, given a sample size of 40 bags of candy, is approximately 0.8438 or 84.38%.
The probability that the average weight of our sample is greater than 15.8 oz, we need to use the concept of the sampling distribution of the sample mean and the Central Limit Theorem.
Given:
Population mean (μ) = 16 oz.
Population standard deviation (σ) = 1.25 oz.
Sample size (n) = 40 bags of candy.
The Central Limit Theorem states that for a large enough sample size (typically considered n > 30), the sampling distribution of the sample mean will be approximately normally distributed, regardless of the shape of the population distribution.
In this case, we can assume that the sampling distribution of the sample mean is approximately normally distributed.
To calculate the probability, we need to standardize the sample mean using the z-score formula:
z = (x - μ) / (σ / sqrt(n))
where x is the given value (15.8 oz), μ is the population mean, σ is the population standard deviation, and n is the sample size.
Substituting the values:
z = (15.8 - 16) / (1.25 / sqrt(40))
z = -0.2 / (1.25 / 6.3246)
z = -0.2 / 0.1988
z ≈ -1.006
Now, we need to find the probability that the standardized sample mean is greater than -1.006. Since we want the probability of the sample mean being greater than 15.8 oz, we need to find the area under the normal curve to the right of z = -1.006.
Using a standard normal distribution table or a calculator, we can find that the corresponding probability is approximately 0.8438.
Therefore, the probability that the average weight of our sample is greater than 15.8 oz, given a sample size of 40 bags of candy, is approximately 0.8438 or 84.38%.

As a salesperson at Scrapbooks and
Treasures, Alysse receives a monthly
base pay plus commission on all that she
sells. If she sells $500 worth of
merchandise in one month, she is paid
$515. If she sells $900 of merchandise in
one month, she is paid $607.
Find Alysse's total salary function, s(x), when
she sells x dollars of merchandise.
s(x)=
Answer:
s(x) = 0.23x + 400
Step-by-step explanation:
Let x = cost of merchandise sold
We start by finding the slope which is the percent of commission Alysse receives.
Let's start with doing 607 - 515. This is because we are subtracting the commissions, which also can be y2 - y1. Then, we do 900-500=400 (x2-x1). This is how to find the slope of the function. [tex]\frac{y2-y1}{x2-x1}=\frac{92}{400} =0.23[/tex], 0.23 being the slope.
s(x) = b+0.23x, now substitute values making the money received as s(x).
515 = b+0.23(500)
515=b+115
-115 -115
400 = b
607 = 400+0.23(900)
607 = 400 + 207
607 = 607
So, s(x) = 0.23x + 400

Find the y-intercept and the slope of the line.
-8x -4y =5
Answer:
[tex]\sf m = -2\\\\y-intercept =\dfrac{-5}{4}[/tex]
Step-by-step explanation:
Slope and y-intercept of the line:
Write the equation in slope y-intercept form: y =mx +c
Here, m is the slope and c is the y-intercpet.
To isolate y, add 8x to both side,
-8x - 4y = 5
-4y = 8x + 5
Now, divide the entire equation by (-4),
[tex]\sf \dfrac{-4y}{-4}=\dfrac{8x}{-4} + \dfrac{5}{-4}\\\\\\y = -2x -\dfrac{5}{4}[/tex]
Now, compare with y = mx +c
[tex]\boxed{\sf m= -2}\\\\\\\boxed{\sf y-intercept=\dfrac{-5}{4}}[/tex]
Answer:
y-intercept = -5/4
slope = -2
Step-by-step explanation:
To quickly find the slope and y-intercept of a given linear equation, we can express it in the following form, called the slope-intercept form:
[tex]\boxed{y = mx + c}[/tex],
where:
m ⇒ slope
c ⇒ y-intercept
In order to take the given equation into the slope-intercept form, we have to make y the subject of the equation:
[tex]-8x - 4y = 5[/tex]
⇒ [tex]-4y = 8x + 5[/tex] [Adding 8x to both sides of the equation]
⇒ [tex]y = -\frac{1}{4}(8x + 5)[/tex] [Dividing both sides of the equation by -4]
⇒ [tex]y = -2 x - \frac{5}{4}[/tex]
Comparing the above equation with the slope-intercept form, we can see that m = -2 and c = -5/4.
Therefore, y-intercept = -5/4, and slope = -2.

Can I have help finding the area
Answer: For Area A, 60
For Area B, 16
For Area C, 16
For the entire shape, 92
Step-by-step explanation:
If you look at the top of the entire shape, it says the width is 10 cm, that means 10 cm's for the entire width and not just shape A.
If you look at shape B, it says the width is 4 cm, that means 4 out of those 10 cm's are for B and not A but we dont need the width of shape B, so we subtract that 4 bc it isnt necessary since its not in shape A
if you look at the left of shape A, it says 10 cm for the height, when finding area for a rectangle, always do width x height. We have both the width and the height so now we just multiply them, 10 x 6 = 60
Answer:
A = 60cm^2
Step-by-step explanation:
Given:
Length of figure: A = 10cm
Width of figure: B = 10 - 4 = 6cm
Figure A is rectangular in nature.
So, the Area of the figure: A = 1 x b = 10 x 6 = 60cm^2

The horizontally compressed function is [tex]\(\text{g(x)} = x^2 + 6\)[/tex]. The correct option is OC. [tex]\(\text{g(x)} = x^2 + 6\)[/tex].
To horizontally compress the function [tex]f(x) = x^2[/tex], we can modify the equation by introducing a horizontal compression factor. Let's call the compressed function [tex]g(x)[/tex].
The general equation for a horizontally compressed function can be expressed as [tex]g(x) = f(ax)[/tex], where a is the compression factor.
In this case, we want to compress [tex]f(x) = x^2[/tex]. Let's choose a compression factor of [tex]\frac{1}{2}[/tex].
Therefore, the equation for [tex]g(x)[/tex] would be:
[tex]\[ g(x) = f\left(\frac{x}{2}\right) = \left(\frac{x}{2}\right)^2 \][/tex]
Simplifying this equation, we have:

The value of the missing probability for the given probabilities and condition of independent events is equal to 0.45.
Here,
Probability of the events A and B are,
P(A) = 7/10
P(A or B) = 167/200
Apply the formula for the probability of the union of two events,
P(A or B) = P(A) + P(B) - P(A and B)
Since events A and B are independent, we know that,
P(A and B) = P(A) x P(B)
This implies,
P(A or B) = P(A) + P(B) - P(A) x P(B)
Substitute the values we have,
⇒ 167/200 = 7/10 + P(B) - (7/10) x P(B)
⇒ 167/200 = [ 7 + 10P(B) - 7P(B) ] /10
⇒167/20 = 7 + 3P(B)
⇒3P(B) = 167/20 - 7
⇒ 3P(B) = (167 - 140)/20
⇒3P(B) = 27 /20
⇒P(B) = 9/20
⇒P(B) = 0.45
Therefore, the value of the probability P(B) is equal to 0.45.

What measurement is equal to 1 2/3 yards
1 2/3 yards is equal to 5 1/3 feet.
How to find the measurement is equal to 1 2/3 yardsTo convert from yards to feet, we know that 1 yard is equal to 3 feet. Therefore, we can calculate:
1 2/3 yards = (1 + 2/3) yards = (3/3 + 2/3) yards = 5/3 yards
Now, to convert yards to feet, we multiply by 3:
5/3 yards * 3 feet/1 yard = 15/3 feet = 5 feet
Therefore, 1 2/3 yards is equal to 5 1/3 feet.
