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.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
10 = -2A + B
That is the system of equations.

Find the midrange for the data items in the given frequency distribution.
Score, x 29 30 31
Frequency, 2 3 4
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.

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

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.
(2.4 times 10 cubed ) timez 9.5 times 10 to the power of 5
Answer: 2280000000
Step-by-step explanation: Yes, I know it is a long number, but 10 cubed = 10 x 10 x 10, which simplified, would be 100 x 10, which is 1000. So, now you do 2.4 x 1000 to get 2400. Now you take that and multiply that by 9.5. Then, you do 10 to the 5th power, which is 100000. Now, you connect it all together, to get 2280000000. Hopefully, I did it right, if not I am sorry :/

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°

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.

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.
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

Use the given information to write and solve a system of linear equations to find the values of x and y.
Answer:
x=5, y=2 | Equations: 4x+y=22 (or see below) and 12x-5y=50
Step-by-step explanation:
Here's my attempt:
First Equation:
Because triangles ΔSTU and ΔXYZ are congruent, then we can say that:
m∠S = m∠X
m∠T = m∠Y
m∠U = m∠Z
We know that m∠X = 130°, and that m∠X = m∠S, so m∠S = 130°
We also know that the sum of angles in a triangle = 180°
We also know the rest of the angles in ΔSTU: 28° and (4x+y)°
So, we can say that ∠S + ∠T + ∠U = 130+28+4x+y = 180 (we can remove the degree sign)
Now, you can either enter this as it is or simplify it: ❗
130+28+4x+y=180
4x+y+158=180
4x+y=22
Second Equation:
We can do the same thing as for the first equation and get the angles of ΔXYZ:
∠X = 130, ∠Y = 8x-6y, ∠Z = 4x+y
Then, add them and set it to 180:
130+8x-6y+4x+y=180
Simplify:
12x-5y+130=180
12x-5y=50
To solve for x and y:
Now, we have to solve the systems.
Let's start with the first one:
4x+y=22
Isolate y:
y=22-4x (Equation 1)
Then, we plug it into the second equation:
12x-5y=50
12x-5(22-4x)=50
12x-110+20x=50
32x=160
x=5
So we got x, but to find y, we need to plug in x into Equation 1 (where we isolated y
y=22-4x
y=22-4(5)
y=22-20
y=2
We have both our x and y values
