The -3 is not in the exponent
Explanation:
The parent function is \(f(x) = 2^x\). Plugging in x = 0 leads to y = 1. So the point (0,1) is on the f(x) curve. Going from (0,1) to (0,-2) is a vertical shift of 3 units downward. To represent this shift, we tack on a "-3" at the end of the f(x) function.
\(g(x) = f(x) - 3\\\\g(x) = 2^x - 3\)
You could look at other points as well, but I find working with x = 0 is easiest.
As a check, plugging x = 0 into g(x) leads to...
\(g(x) = 2^x - 3\\\\g(0) = 2^0 - 3\\\\g(0) = 1 - 3\\\\g(0) = -2\)

5x=20
4r+2
Answer:
x = 12
Step-by-step explanation:
To get the value of x, we use the mid-segment theorem of trapezoid
The theorem is that the mid-segment is half the sum of the other two segments
We have this as
;
5x - 20 = 1/2(2x + 6 + 4x + 2)
2(5x-20) = 6x + 8
5x -20 = 3x + 4
5x -3x = 4 + 20
2x = 24
x = 24/2
x = 12
Consider the market for cars in a small country. Suppose the demand and supply curves for cars have been estimated and are given by D(p) = 1100 - 50p and S(p) = 200 + 100p where D(p) is the quantity demanded when the price for cars is p, and similarly, S(p) is the quantity supplied at price p. NOTE: In your analysis, consider only the areas with non-negative prices. c) Suppose the government imposes a specific tariff T= $1, that effectively raises the prevailing price in the market to p^ = 5.5. At this price, what is the quantity demanded and the quantity supplied of cars? What are the imports/exports of cars?
When the government imposes a specific tariff of $1, the prevailing price in the market increases to p^ = 5.5. We can use the demand and supply equations to find the quantity demanded and the quantity supplied at this price.
Quantity demanded: D(p) = 1100 - 50p = 1100 - 50(5.5) = 1100 - 275 = 825
Quantity supplied: S(p) = 200 + 100p = 200 + 100(5.5) = 200 + 550 = 750
At the price of p^ = 5.5, the quantity demanded is 825 cars and the quantity supplied is 750 cars. Since the quantity demanded is greater than the quantity supplied, there will be imports of cars. The quantity of imports will be the difference between the quantity demanded and the quantity supplied:
Imports = Quantity demanded - Quantity supplied = 825 - 750 = 75
Therefore, at the price of p^ = 5.5, there will be imports of 75 cars. There will be no exports of cars because the quantity demanded is greater than the quantity supplied.

The population growth rate (r) for 2009 in the tiny country of fremont is found as 1.4.
Describe the term population growth rate (r)?The population growth rate (r) shows how fast a population ages over time. A population is growing if the growth rate is positive. A negative growth rate signals a declining trend. A birth rate (b) and mortality rate are the two primary elements that influence population increase (d). People leaving the population to move to another territory or immigrating from a different region may also have a consequence on population increase (emigration, e).All these elements are taken into account when formulating the population growth formula.
r = [(b + i) - (d + e)]/1000
r = population growth rateb = birth rate; 2,000i = immigration rate; 100d = death rate; 500e = emigration rate; 200Put the values in the formula.
r = [(2,000 + 100) - (500 + 200)]/1000
r = 2100 - 700/ 1000

How to find the Fahrenheit temperature of the cup of water, to the nearest degree, after 4.5 minutes.Using Newton's Law of Cooling to find the value of the decay constant k: T = \(Ta + (T0 - Ta) * e^-k*t\)
Substituting the given values, we get:
185 = \(69 + (203 - 69) * e^-k*1.5\)
Simplifying, we get:
\(116 = 134 * e^ \\^{-1.5k}\)
Dividing both sides by 134, we get:
\(0.8657 = e^{-1.5k}\)
Taking the natural logarithm of both sides, we get:
ln(0.8657) = -1.5k
Solving for k, we get:
k ≈ 0.232
Therefore, the value of the decay constant is approximately 0.232.
To find the temperature of the water after 4.5 minutes, we can use Newton's Law of Cooling again, with t = 4.5:
\(T = Ta + (T0 - Ta) * e^-k*t\)
\(T = 69 + (203 - 69) * e^-0.232*4.5\)
T ≈ 153°F

Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury? 0.05 – 0.1y = 0.12 – 0.06y 0.05y 0.1 = 0.12y 0.06 0.05 0.1y = 0.12 0.06y 0.05y – 0.1 = 0.12y – 0.06
The equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.
In the question, we have been asked for the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury.
First, we will find the equations showing the level of mercury in each body of water.
For the first water body:
Initial measure of mercury = 0.05 ppb.
Rate of rising = 0.1 ppb each year.
Number of years = y.
Thus, the equation showing level of mercury = 0.05 + 0.1y.
For the second water body:
Initial measure of mercury = 0.12 ppb.
Rate of rising = 0.06 ppb each year.
Number of years = y.
Thus, the equation showing level of mercury = 0.12 + 0.06y.
We are looking for the equation, to find y, the year in which both bodies of water have the same amount of mercury.
As they will have the same amount of mercury, their respective equations showing the level of mercury should be equal, that is:
0.05 + 0.1y = 0.12 + 0.06y, which is the required equation.
Thus, the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.

What is probability?
Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain to occur.
To solve this problem, we can work backward from (c,d) to (a,b) and check if each step is valid. Specifically, we can use the following observations:
If c < a or d < b, it is impossible to reach (c,d) from (a,b) using the given operations.
If c - a = d - b, we can reach (c,d) from (a,b) using only the second operation. Specifically, we can perform the operation (a, a+b) repeatedly until we reach (c,d).
If c - a != d - b, we can reach (c,d) from (a,b) using a combination of the two operations. Specifically, we can perform the first operation (a,b) -> (a+b,b) repeatedly until we get to a point where c - a = d - b, and then use the second operation to get to (c,d).
Here, we first check if it is impossible to reach (c,d) from (a,b) using the observations above. If not, we perform the second operation as many times as possible to reduce the difference between c and a, and d and b. Once this is done, we check if we have arrived at (a,b).
Therefore, we return "Yes"; otherwise, we return "No".

The measure of angle 1 is (10 x + 8) degrees and the measure of angle 3 is (12 x minus 10) degrees. what is the measure of angle 2 in degrees?
Answer:

Step-by-step explanation:
First set 10x+8 equal to 12x-10 to find that the variable is equal to 9. Then solve for 10(9)+8 which equals 98. Since angle 1 is supplementary to angle two and supplementary angles add up to 180 degrees, subtract 98 from 180 to find that your answer is 82 degrees.
In a survey, 20 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $44 and standard deviation of $10. Estimate how much a typical parent would spend on their child's birthday gift (use a 99% confidence level). Give your answers to one decimal place. Provide the point estimate and margin or err
Based on the survey results, a typical parent would spend around $44 on their child's birthday gift, with a margin of error of approximately $2.9 at a 99% confidence level.
To estimate how much a typical parent would spend on their child's birthday gift, we use the sample mean and standard deviation as estimates of the population parameters. The sample mean of $44 serves as the point estimate for the population mean.
To determine the margin of error, we use the standard error, which is the standard deviation divided by the square root of the sample size. In this case, the standard error is approximately $2.5 (standard deviation of $10 divided by the square root of 20). Multiplying the standard error by the critical value corresponding to a 99% confidence level (z-value of 2.58 for a large sample size) gives us the margin of error.
Therefore, the typical amount spent on a child's birthday gift is estimated to be $44, with a margin of error of approximately $2.9. This means that we can be 99% confident that the true mean amount spent by parents falls within the range of $41.1 to $46.9.

D. (2, 3) and (76)
From the following sets of ordered pairs, line c, (3, 6) and (5, 1), has a negative slope.
To determine the slope of a line given two points, we can use the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
If the slope is negative, it means the line is decreasing as we move from left to right, or in other words, it has a negative slope.
Let's apply the formula to each set of ordered pairs:
A. slope = (1 - 5) / (0 - 5) = -4 / -5 = 4/5 (positive slope)
B. slope = (-1 - 3) / (-4 - 2) = -4 / -6 = 2/3 (positive slope)
C. slope = (1 - 6) / (5 - 3) = -5 / 2. (negative slope)
D. This set has only one point (2, 3) and is therefore not sufficient to define a line.
