The decay of the radioactive substance can be modeled by the exponential decay function:
y = a(1 - r)^t
where:
- y is the amount of substance present after t hours
- a is the initial amount of substance (in grams), which is 120 grams in this case
- r is the decay rate per hour, which is 18% or 0.18 in decimal form
- t is the time elapsed in hours
Plugging in the values we get:
y = 120(1 - 0.18)^t
Simplifying:
y = 120(0.82)^t
So this is the equation that represents the number of grams, y, present after t hours, given the initial amount of 120 grams and a decay rate of 18% per hour.

Mayumi was asked to determine whether quadrilateral rstu is a trapezoid given the vertices r(-2, 3), s(1, 4), t(1, -4) and u(-2, 1). she noticed that the slopes of ru and st are undefined, so she concluded that the quadrilateral could not be a trapezoid. do you agree? explain.
No, I do not agree with Mayumi's conclusion that the quadrilateral RSTU cannot be a trapezoid just because the slopes of RU and ST are undefined.
RSTU is a trapezoid with RU and ST are parallel and have the same x-coordinates.
A trapezoid is defined as a quadrilateral with at least one pair of parallel sides.
The fact that the slopes of RU and ST are undefined does not necessarily mean that they are not parallel.
As vertical lines have undefined slopes and are parallel to each other.
To determine if RSTU is a trapezoid,
Mayumi should check if any pair of opposite sides are parallel.
The slopes of the two pairs of opposite sides RS and TU, and RU and ST and check if they are equal.
Slope of RS = (4 - 3)/(1 - (-2))
= 1/3
Slope of TU = (1 - (-4))/(-2 - 1)
= -5/3
Slope of RU is undefined (vertical line)
Slope of ST is undefined (vertical line)
Since the slopes of RS and TU are not equal, they are not parallel.
The slopes of RU and ST are undefined does not give us any information about their parallelism.
Check at other properties of the quadrilateral to determine if they are parallel.
One property is the coordinates of the points.
If we draw the quadrilateral, RS and TU are not parallel, but RU and ST are parallel and have the same x-coordinates.
Therefore, quadrilateral RSTU is a trapezoid with bases RS and TU, and legs RU and ST.

A pitcher contains 13 cups of iced tea. You drink 1. 75 cups of the tea each morning
and 1. 5 cups of the tea each evening. When will you run out of iced tea?
You will run out of iced tea in 5.33 days.
To calculate this, we need to first determine how much tea you drink each day:
1.75 cups in the morning + 1.5 cups in the evening = 3.25 cups per day.
Then, we can divide the total amount of tea by the amount you drink per day to find out how many days the tea will last:
13 cups ÷ 3.25 cups per day ≈ 4 days.
However, we need to account for the fact that you won't run out of tea at the end of the day, so we need to round up to the nearest day:
ceil(4 days) = 5 days.
Finally, we need to account for the partial day on the fifth day, which we can calculate by finding how much tea you drink in the morning before running out:
1.75 cups in the morning - (5 days x 3.25 cups per day) = 0.5 cups.
So, you will run out of iced tea on the fifth day in the evening, after drinking 1.5 cups. Therefore, you will run out of iced tea in 5.33 days.

The change in water level of a lake is shown in the table. How much did the water level change between Weeks 2 and 3?
The rate of change for the water level between Weeks 2 and 3 is: D. 3 7/8.
How to calculate or determine the rate of change or slope of a line?In Mathematics and Geometry, the gradient, rate of change, or slope of any straight line can be determined by using the following mathematical equation;
Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change (slope) = rise/run
Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)
By substituting the given data points into the formula for the slope of a line, we have the following;
Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)
Rate of change (slope) = (1 5/8 + 2 1/4)/(3 - 2)
Rate of change (slope) = (13/8 + 9/4)/(1)
Rate of change (slope) = 3 7/8

Enter the value of c when the expression 21. 2x + c is equivalent of to 5. 3(4x - 2. 6).
The value of c is 21.8.
We can solve for c by simplifying the expression on the right side of the equation and equating it to the expression on the left side.
Starting with the right side, we distribute the 3 across the parentheses:
5 * 3 * (4x - 2.6) = 60x - 13
Now, we can set this equal to the expression on the left and solve for c:
21.2x + c = 60x - 13
c = 60x - 13 - 21.2x
c = 38.8x - 13
However, we are asked to find the value of c, not in terms of x. Since we were not given a specific value for x, we cannot solve for c exactly. Therefore, we can only express the value of c in terms of x, which is c = 38.8x - 13.

Sabrina is 4 feet tall and casts a shadow that is 3. 5 feet tall. A nearby pole is 10 feet tall. How tall will the pole’s shadow be if Sabina and the pole are proportional? Leave your answer as a fraction
If Sabina and the pole are proportional, then the pole’s shadow will be 35/4 feet tall.
Since Sabrina is 4 feet tall and casts a 3.5-foot shadow, we can set up a proportion comparing the heights and shadow lengths: Sabrina's height (4 feet) / her shadow (3.5 feet) = pole's height (10 feet) / pole's shadow (x).
This proportion can be represented as: 4/3.5 = 10/x. To solve for x (the length of the pole's shadow), we can cross-multiply:
4 * x = 3.5 * 10
4x = 35
Now, divide both sides by 4:
x = 35/4
So, the pole's shadow will be 35/4 feet long when both Sabrina and the pole are proportional. This fraction represents the pole's shadow length in relation to the given heights and shadow lengths.

You purchased a home this year for $315,000. You applied for homestead exemption and were able to take off $50,000 of the appraised value for taxes. The taxes in your county are 1.22%. How much do you have to pay in property taxes?
You need to pay $3,243.50 in property taxes.
The appraised value of the house after setting out the homestead exemption is $315,000 - $50,000 = $265,000.
To calculate the assets taxes, we need to multiply the appraised cost by means of the tax rate, which is 1.22% or 0.0122 as a decimal:
property taxes = $265,000 x zero.0122 = $3,243.50
Therefore, you have to pay $3,243.50 in property taxes.

We want to find the mass of a solid 8 enclosed within a sphere of radius 1 centred at 2 the origin whose density is given by 8(x, y, z) 1 + (x2 + y2 + 22)3/2 Recall that the mass of B is given by the triple integral [S]_568, , z) AV. Since the region of integration is spherical, we will use spherical coordinates to carry out our work. (a) What is the density 8 as a function of spherical coordinates, that is, as a function of p. 0, and ? (Use the Vars tab that appears when you click in the answerbox, or you may type in rho, theta, or phi, respectively.) Answer: 8(0,0,0) (b) In spherical coordinates the bounds of integration for p. 0, and 6 are given by SP SOS sºs (C) What is the mass of the solid ? (If you enter your answer using a decimal approximation, then round your answer to three decimal places.)
A. 8(p, phi, theta) = 8p sin(phi) cos(theta) / (1 + p^2 + 2p cos(phi))^(3/2)
B. ∫0^(2π) ∫0^π ∫0^1 8p sin(phi) cos(theta) / (1 + p^2 + 2p cos(phi))^(3/2) p^2 sin(phi) dp d(phi) d(theta)
C. the mass of the solid 8 enclosed within the sphere is approximately 8.378.
(a) Using the conversion formulas for spherical coordinates, we have:
x = p sin(phi) cos(theta)
y = p sin(phi) sin(theta)
z = p cos(phi)
Substituting these expressions into the given density function, we get:
8(x, y, z) = 8(p sin(phi) cos(theta), p sin(phi) sin(theta), p cos(phi))
= 8p sin(phi) cos(theta) / (1 + p^2 + 2p cos(phi))^(3/2)
Therefore, the density 8 as a function of spherical coordinates is:
8(p, phi, theta) = 8p sin(phi) cos(theta) / (1 + p^2 + 2p cos(phi))^(3/2)
(b) Since the solid 8 is enclosed within a sphere of radius 1 centred at 2 the origin, we have:
0 ≤ p ≤ 1
0 ≤ theta ≤ 2π
0 ≤ phi ≤ π
Therefore, the bounds of integration in spherical coordinates are:
∫0^(2π) ∫0^π ∫0^1 8p sin(phi) cos(theta) / (1 + p^2 + 2p cos(phi))^(3/2) p^2 sin(phi) dp d(phi) d(theta)

Are the events "having a dog" and "having a cat" independent from each other?
a) Cannot tell with the given information
b) Yes, because P(cat) = P(cat | dog) and P(dog) = P(dog | cat)
c) The events are disjoint
d) No, because P(cat) is not equal to P(cat | dog) and P(dog) is not equal to P(dog | cat)
Option A) Cannot tell with the given information as the question doesn't provide any information about the relationship between having a dog and having a cat.
Without additional information, we cannot determine if these events are independent, dependent, disjoint, or have any other relationship. Independent events are events in which the occurrence or non-occurrence of one event does not affect the occurrence or non-occurrence of the other event.
In other words, the probability of one event happening does not depend on whether or not the other event happens.
Formally, events A and B are independent if and only if:
P(A ∩ B) = P(A) * P(B)
Where P(A) is the probability of event A occurring, P(B) is the probability of event B occurring, and P(A ∩ B) is the probability of both events A and B occurring simultaneously.
If the above equation holds true, then we can say that events A and B are independent. If not, then events A and B are dependent.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
A probability can be classified as experimental or theoretical, as follows:
Experimental -> calculated after previous trials.Theoretical -> calculate before any trial.Over a small number of trials, these two probabilities can be different, but over a large number of trials, their values get closer.
The dice has eight sides, hence the theoretical probability of rolling a six is given as follows:
1/8 = 0.125 = 12.5%.
(each of the eight sides is equally as likely, and a six is one of these sides).
The experimental probabilities are obtained considering the trials, hence:
100 trials: 20/100 = 0.2 = 20%.400 trials: 44/400 = 0.11 = 11%.(given in the problem).

A community center charges x dollars for a summer activity if individuals are signed up before the day of the activity. Individuals who sign up the day of the activity are charged a fee of x plus 0. 20 x dollars. Which expression also represents the fee for signing up the day of the activity, and what does it mean about the fee?.
The expression that represents the fee for signing up the day of the activity is x + 0.20x. This means that fee for signing up the day of the activity is original fee (x) plus an additional 20% of original fee (0.20x).
For example, if the community center charges $50 for signing up before the day of the activity, then the fee for signing up the day of the activity would be:
$50 + ($50 x 0.20) = $50 + $10 = $60
So, individuals who sign up the day of the activity are charged a higher fee than those who sign up before the day of the activity, because they are charged the original fee plus an extra 20% of the original fee.

The oil spill is increasing by approximately 0.58% per hour.
An oil spill is spreading such that its area is given by the exponential function A(t) = 250(1.15)^t, where A is the area in square feet and t is the time that has elapsed in days. To find the percent increase per hour, first convert the time from days to hours by replacing t with (t/24), since there are 24 hours in a day.
A(t) = 250(1.15)^(t/24)
To determine the hourly percent increase, find the growth factor for one hour (t=1) and subtract 1 to get the percentage:
A(1) = 250(1.15)^(1/24) ≈ 250(1.0058)

The Average Rate Of Change In The Interval (0, 2) Of The Function F F(X) = X^2 – 3x Is
To find the average rate of change of a function in a given interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the length of the interval.
In this case, the interval is (0,2) and the function is f(x) = x^2 - 3x.
At the left endpoint, x=0, we have f(0) = 0^2 - 3(0) = 0.
At the right endpoint, x=2, we have f(2) = 2^2 - 3(2) = -2.
Therefore, the difference in the function values is f(2) - f(0) = -2 - 0 = -2.
The length of the interval is 2 - 0 = 2.
So the average rate of change of f(x) over the interval (0,2) is:
(-2)/2 = -1
Therefore, the average rate of change of f(x) over the interval (0,2) is -1.
Hi! To find the average rate of change in the interval (0, 2) for the function f(x) = x^2 - 3x, you can use the following formula:
Average Rate of Change = (f(b) - f(a)) / (b - a)
In this case, a = 0 and b = 2. First, calculate the function values at these points:
f(0) = (0)^2 - 3(0) = 0
f(2) = (2)^2 - 3(2) = 4 - 6 = -2
Now, apply the formula:
Average Rate of Change = (f(2) - f(0)) / (2 - 0) = (-2 - 0) / (2) = -2 / 2 = -1
So, the average rate of change in the interval (0, 2) for the function f(x) = x^2 - 3x is -1.

time = distance / speed
Given:
Distance from the Sun to Earth = 9.3 x 10^7 miles
Speed of light = 1.86 x 10^5 miles per second
Plugging in the values into the formula, we have:
time = (9.3 x 10^7 miles) / (1.86 x 10^5 miles per second)
To simplify, we can divide the numerator and denominator by 10^5 to cancel out the units:
time = (9.3 x 10^7) / (1.86 x 10^5) seconds
Next, we can divide the numbers in scientific notation:
time = (9.3 / 1.86) x (10^7 / 10^5) seconds
Simplifying further:
time = 5 x 10^2 seconds
Therefore, light takes approximately 500 seconds to travel from the Sun to Earth.

The general form of the primitive of the function f (x) = 6 sin (2) / cos (2) is F (x) = ______ + C
The integral of f(x) can be found by using the substitution u = cos(x), du = -sin(x) dx. Thus, we have:
∫ (6 sin(2x) / cos(2x)) dx = -3 ∫ (2 sin(2x) / cos²(2x)) (-2cos(x)) dx
= 6 ∫ (sin(u) / u²) du
This integral can be evaluated using integration by parts, with u = sin(u) and dv = u⁻² du, giving:
6 ∫ (sin(u) / u²) du = -6 sin(u) / u + 6 ∫ (cos(u) / u) du
Substituting back u = cos(x), we have:
6 ∫ (sin(x) / cos²(x)) dx = -6 tan(x) + 6 ln |cos(x)| + C
Since tan(x) = sin(x) / cos(x) and cos²(x) = 1 - sin²(x), we have:
f(x) = 6 sin(x) / cos²(x) = 6 sin(x) / (1 - sin²(x)) = -6/(sin(x) - 1/sin(x))
Therefore, the general form of the primitive of f(x) is:
F(x) = -6 ln |sin(x) - 1/sin(x)| + C

Gas prices are on the rise this summer as more Americans travel, Prices have increased by 40% from last summer's price, which averaged $2. 26 per gallon. Jonah's mom's car takes 14 1/2 gallons of gas to fill up. Find the cost that Jonah's mom would have to spend after the 40% increase in gas prices if she fills up her tank the entire 14 1/2 gallons.
Jonah's mom's would have to spend $45.878 to fill up her tank after the 40% increase in gas prices if her car takes 14 1/2 gallons of gas to fill up.
To find the cost that Jonah's mom would have to spend after the 40% increase in gas prices to fill up her 14 1/2 gallon tank, we need to follow these steps:
1. Find the increased price per gallon by multiplying last summer's price ($2.26) by 1.40 (since there's a 40% increase): $2.26 x 1.40 = $3.164 per gallon.
2. Convert 14 1/2 gallons to a decimal: 14.5 gallons.
3. Multiply the increased price per gallon ($3.164) by the number of gallons needed to fill up the tank (14.5 gallons): $3.164 x 14.5 = $45.878.
So, after the 40% increase in gas prices, Jonah's mom would have to spend $45.878 to fill up her 14 1/2 gallon tank.

Let C = {factors of 12}
Work out n(C)
The value or n(C) based on the information will be 6.
How to explain the FactorIn mathematics, a factor is a number or algebraic expression that divides another number or expression without leaving a remainder. More formally, if a is a factor of b, then b can be expressed as a product of a and some other number or expression.
For example, in the expression 12 = 2 x 2 x 3, the numbers 2 and 3 are factors of 12. Similarly, in the expression x² - 4, (x - 2) and (x + 2) are factors because if we multiply them together we get x² - 4.
The factors of 12 are 1, 2, 3, 4, 6, and 12. Therefore, the set C contains six elements. Hence, n(C) = 6.

Does anyone know the answer?
Answer:
B. ∠FBG
Step-by-step explanation:
When an angle is in the three letter form, the first letter is the first line that forms the angle, the second letter is where the angle is located, and third letter is the line that forms the angle with the first line.
Thus, we can see that line E combines with line F, and the actual angle is located at point B.
The two angles adjacent to ∠EBF are ∠DBE and ∠FBG. Only ∠FBG is one of the answer choices so this is our final answer.
