Find the end behavior of the function:
f(x) = 2^-xsin3x
Answer:
The end behavior of the function f(x) = 2^-xsin3x is that it approaches 0 as x approaches positive infinity and approaches infinity as x approaches negative infinity.
Step-by-step explanation:
The end behavior of a function refers to how the function behaves as the input values approach positive infinity or negative infinity.For example, consider the function f(x) = 2^-xsin3x as x approaches positive infinity and negative infinity; its behavior is that it begins to oscillate between 1, -1/2, and 0. The end behavior of the function f(x) = 2^-xsin3x is that it approaches infinity as x approaches positive infinity.The same is true for the function g(x), where the end behavior is to oscillate between 1, -1/2, and 0 with respect to negative infinity.Write a proof, that AJKN ALMN (15 points)

Which system of equations can be used to determine the values of A and B?
The system of equations that should be used is the second one:
-15 = 5A
10 = -2A + B
Which system of equations can be used?Here we have the following equation:
[tex]\frac{-15x + 10}{(5x - 2)^2} = \frac{A}{5x - 2} + \frac{B}{(5x - 2)^2}[/tex]
If we multiply and divide the first therm in the right side by (5x - 2) we will get:
[tex]\frac{-15x + 10}{(5x - 2)^2} = \frac{A*(5x - 2)}{(5x - 2)^2} + \frac{B}{(5x - 2)^2}[/tex]
The numerators must be equal, then we can write:
-15x + 10 = A*(5x - 2) + B
-15x + 10 = A*5x - 2A + B
Then we can write two equations, one that has x as a factor and other that does not, these are:
-15 = 5A

original equations: S(p) = -200 + 50p and D(p) = 1060 - 55p
please find the equilibrium price and quantity of the two equations. I think I already set up the equation for the equilibrium price here, though no guarantee that I did it right.
Qd = 1060 - 55p = Qs = -200 + 50p
The equilibrium price is 12 and the equilibrium quantity is 400.
How to find the equilibrium price and quantity?It should be noted that on order to fund equilibrium price and quantity, we've to equate the quantity supplied and demanded. This will be:
Qd = 1060 - 55p
Qs = -200 + 50p
Qd = Qs
1060 - 55p = -200 + 50p
Collect like terms
-55p - 50p = -200 - 1060
-105p = -1260
Divide
p = 1260 / 105
p = 12
The equilibrium price is 12
Equilibrium quantity = -200 + 50p
= -200 + 50(12)
= -200 + 600

hope this helps by now
Answer:
Blue: 1/5
Step-by-step explanation:
To find the rate of change you use your slope formula which is y2-y1 over x2-x1.
You'd set your equation and you'd get 4-2 over 20-10. You solve and you get 2/10 and because it isn't one of the answer choices you have to simplify it. To simplify it you find the common number they both share and they both share 2 so you divide both by 2. 2 divided by 2 is 1 and 10 divide by 2 is 5. So then the rate of change or slope is 1/5.
A wagon is being pulled by a 300-pound force that makes a 30° angle with the ground. what are the horizontal and vertical components of the force vector? a. the horizontal is 150 pounds, and the vertical is 260 pounds.b. the horizontal is 260 pounds, and the vertical is 150 pounds. c. the horizontal is 346 pounds, and the vertical is 600 pounds.d. the horizontal is 600 pounds, and the vertical is 346 pounds.
Answer: B
Step-by-step explanation: TRUST
The horizontal component of the force vector is 260 pounds, and the vertical component is 150 pounds. (Option B).
How to Solve for the Component of the Force Vector?To find the horizontal and vertical components of the force vector, we can use trigonometry. The horizontal component is the force acting in the direction parallel to the ground (x-axis), and the vertical component is the force acting in the direction perpendicular to the ground (y-axis).
Given that the force is 300 pounds and makes a 30° angle with the ground, we can calculate the components as follows:
Horizontal component (F_horizontal) = Force * cos(angle)
Vertical component (F_vertical) = Force * sin(angle)
Inserting in the values:
Horizontal component (F_horizontal) = 300 pounds * cos(30°)
Vertical component (F_vertical) = 300 pounds * sin(30°)
Now, let's calculate:
Horizontal component (F_horizontal) = 300 pounds * 0.866 (rounded to 3 decimal places, cos(30°) ≈ 0.866)
F_horizontal ≈ 259.8 pounds
Vertical component (F_vertical) = 300 pounds * 0.5 (rounded to 3 decimal places, sin(30°) ≈ 0.5)
F_vertical ≈ 150 pounds
Therefore, the required components of the force vector are approximately 260 pounds and 150 pounds.

A Web music store offers two versions of a popular song. The size of the standard version is 2.7 megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1420 downloads of the song, for a total download size of 5436 MB. How many downloads of the high-quality version were there?
Answer: 890 downloads the high-quality version
Step-by-step explanation:
Let x be the number of downloads of the high-quality version
1420-x be the number of downloads of the standard version
So, we have the equation
4.5x + 2.7(1420-x) = 5436
4.5x + 3834 - 2.7x = 5436
1.8x + 3834 = 5436
Subtract 3834 on both sides
1.8x = 1602
x = 890
Washington Plastic Products pays Nancy Bell a $1710 monthly salary plus a 14% commission on merchandise she sells each month. Assume Nancy's sales were
$59,400 for last month.
Calculate the following amounts:
1: Amount of Commission
2: Gross pay
To calculate the amount of commission that Nancy Bell earned last month, we can use the following formula:
Commission = Sales * Commission Rate
In this case, the sales are $59,400 and the commission rate is 14%, so the commission is:
Commission = $59,400 * 14% = $8,356
To calculate Nancy's gross pay, we can add her salary to her commission:
Gross Pay = Salary + Commission
Gross Pay = $1,710 + $8,356 = $10,066
Therefore, Nancy earned $8,356 in commission and her gross pay was $10,066.

(a) whenever hoffman rolls a first ball of a frame, the probability of making a strike is 0.5. find the probability that hoffman rolls a perfect game. (round your answers to six decimal places.)
There are 10 frames, thus the probability of Hoffman rolling a strike in a single frame is 0.5. The probability of Hoffman rolling a perfect game is 0.000779.
The probability of Hoffman rolling a perfect game is the sum of the probabilities of him rolling a strike in each of the 10 frames.
There are 10 frames, thus the probability of Hoffman rolling a strike in a single frame is 0.5.
To calculate the probability of Hoffman rolling a perfect game, we must multiply 0.5 by 10, which is equal to 0.5. This gives us a probability of 0.000779 or 0.000779 rounded to six decimal places.

The midrange for the data items in the given frequency distribution is 30.5.
What is the midrange for the data items in the given frequency distribution.?Generally, To find the midrange for the data items in the given frequency distribution, we need to calculate the midpoint of each score range. The midpoint of a range is calculated by taking the average of the lower and upper bounds of the range.
For the first score range (29-30), the lower bound is 29 and the upper bound is 30, so the midpoint is (29 + 30) / 2 = 29.5.
For the second score range (30-31), the lower bound is 30 and the upper bound is 31, so the midpoint is (30 + 31) / 2 = 30.5.
Therefore, the midrange for the data items in the given frequency distribution is 30.5.

Amadou and his children went into a grocery store and he bought $9 worth of apples and bananas. Each apple costs $1 and each banana costs $0.50. He bought 4 times as many apples as bananas. By following the steps below, determine the number of apples, x, and the number of bananas, y, that Amadou bought.
Determine three ways to have 4 times as many apples as bananas
Answer:
To have 4 times as many apples as bananas, Amadou could have bought 4 apples for every 1 banana, or 8 apples for every 2 bananas, or 16 apples for every 4 bananas.
4 apples : 1 banana
8 apples : 2 bananas
16 apples : 4 bananas
We can use the fact that the total cost of the apples and bananas was $9 to determine the number of apples and bananas that Amadou bought. Since each apple costs $1, Amadou bought 9 apples if he bought no bananas, or 7 apples if he bought 2 bananas, or 5 apples if he bought 4 bananas.
9 apples : 0 bananas
7 apples : 2 bananas
5 apples : 4 bananas
Therefore, the possible combinations of apples and bananas that Amadou could have bought are 9 apples and 0 bananas, 7 apples and 2 bananas, or 5 apples and 4 bananas.
What are vertical and adjacent angles? How do you find the measure of an unknown angle using these relationships? Give an example and show your work.
Vertical angles are two angles that are opposite each other and share a common vertex. Adjacent angles are two angles that share a common side and vertex.
To find the measure of an unknown angle using these relationships, you can use the vertical angle theorem which states that if two angles are vertical, then they have equal measure. For example, if angle A and angle B are vertical angles, then angle A = angle B.
Example:
Given: Angle A = 40°
Find the measure of angle B
Solution:
Since angle A and angle B are vertical angles, then angle A = angle B
Therefore, the measure of angle B = 40°
