what is expression ?
It is possible to do mathematical operations like addition, subtraction, division, and multiplication. An expression is put together as follows: Number, expression, and mathematical operator.
a) f(x) + xg(x)
First, we need to find xg(x), which is x multiplied by g(x):
[tex]xg(x) = x(x^{2} + 5x + 2) = x^{3} + 5x^{2} + 2x\\\\f(x) + xg(x) = 2x^{2} - x - 4 + x^{3} + 5x^{2} + 2x\\\\f(x) + xg(x) = x^{3} + 7x^{2} + x - 4[/tex]
Therefore, [tex]f(x) + xg(x) = x^{3} + 7x^{2} + x - 4.[/tex]
b) [f(x)]²
To square f(x), we can simply multiply it by itself:
[f(x)]² = (2x² - x - 4)(2x² - x - 4)
[tex][f(x)]² = 4x^{4} - 4x^{3} - 15x^{2} + 8x + 16[/tex]
c) f²(x)
Since f²(x) means f(x) times f(x), we can use the distributive property of multiplication:
[tex]f^{2} (x) = f(x) * f(x)\\\\f^{2}(x) = (2x^{2} - x - 4)(2x^{2} - x - 4)[/tex]
[tex]f^{2}(x) = 4x^{4} - 4x^{3} - 15x^{2} + 8x + 16[/tex]
d) gf(x)
To find gf(x), we need to multiply g(x) by f(x):
[tex]gf(x) = (x^{2} + 5x + 2)(2x^{2} - x - 4)[/tex]
Multiplying each term of g(x) by each term of f(x), and simplifying:
gf(x) = 2x⁴ + 8x³ - 13x² - 3x - 8
Therefore, [tex]gf(x) = 2x^{4} + 8x^{3} - 13x^{2} - 3x - 8.[/tex]

5You can form a right triangle by cutting a _______ in half diagonally.
You can form a right triangle by cutting a square in half diagonally.
A square is a quadrilateral with four equal sides and four right angles. When a square is cut in half diagonally, it forms two congruent right triangles. The two halves of the square, which are the two legs of the right triangle, are equal in length.
The diagonal of the square, which is the hypotenuse of the right triangle, can be found using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse).
Therefore, in a right triangle formed by cutting a square in half diagonally, the length of the hypotenuse can be found by taking the square root of the sum of the squares of the lengths of the two legs.
In summary, cutting a square in half diagonally allows us to form two congruent right triangles with equal leg lengths, making it a suitable shape to form a right triangle.

Write the equation of an exponential function that passes through the points
(1,12) and (3,108)
Answer:
[tex]f(x)=4(3)^x[/tex]
Step-by-step explanation:
The general equation for an exponential function is:
[tex]\boxed{f(x) = ab^x}[/tex]
where:
a is the initial value or y-intercept.b is the base or growth factor.To find the values of a and b that satisfy the given conditions, we can use the two points (1, 12) and (3, 108) to form a system of equations:
[tex]\begin{cases}12 = ab^1\\108 = ab^3\end{cases}[/tex]
Divide the second equation by the first equation to eliminate a:
[tex]\dfrac{ab^3}{ab} = \dfrac{108}{12}[/tex]
[tex]b^2=9[/tex]
[tex]\sqrt{b^2}=\sqrt{9}[/tex]
[tex]b=3[/tex]
Substitute the found value of b into the first equation and solve for a:
[tex]12&=3a[/tex]
[tex]\dfrac{12}{3}=\dfrac{3a}{3}[/tex]
[tex]4=a[/tex]
[tex]a=4[/tex]
Therefore, the equation of the exponential function that passes through the points (1, 12) and (3, 108) is:
[tex]\boxed{f(x) = 4(3)^x}[/tex]
Answer:
y=4(3^x).Step-by-step explanation:
To find the equation of an exponential function passing through the given points (1,12) and (3,108),
we can use the standard exponential form y=a(b^x). We know that when x=1, y=12,
so we can substitute these values into the equation to find a.
So 12 = a(b^1). Similarly, when x=3, y=108, so 108 = a(b^3). We can divide the second equation by the first to eliminate a and get (108/12) = b^2, or 9 = b^2. Thus, b=3 (taking only the positive root). We can now substitute this value of b into either equation to find a. Using the first equation, we get 12 = a(3^1), so a=4. Therefore, the exponential function passing through the given points is y=4(3^x).

The value of (a) in given triangle is approximately 7.44 cm.
What do you mean by triangle?A triangle is a three-sided polygon consisting of three sides and three vertices. The most important property of a triangle is that the sum of its interior angles is 180 degrees.
Let ΔABC is a triangle
Given ∠ B = 75°
∠ C = 31.8°
AB = 12cm
AC = 22cm
find BC = ?
We can use the law of cosines to solve for BC:
BC² = AB² + AC² – 2(AB)(AC)cos(B)
We know that angle B = 75 degrees, so we can substitute:
BC² = 12² + 22² - 2(12)(22)cos(75)
Evaluating cos(75) with a calculator, we get:
BC² ≈ 144 + 484 - 572.59
BC² ≈ 55.41
Taking the square root of both sides gives us:
BC ≈ 7.44
Therefore, BC is approximately 7.44 cm.

a golf ball is hit so that it travels a horizontal distance of 440 feet and reaches a maximum height of 190 feet
using your understanding of parametric equations for projectile motion, what is the angle the ball takes off?
The requried, quadratic equation that models the path of the golf ball, is 16.0850t² - 110.560t - 190 = 0 and the angle the ball takes off is 64.4⁰.
The motion of the golf ball can be modeled using two equations, one for the vertical motion and another for the horizontal motion.
The equation for the vertical motion of the ball is given by:
h = V₀t - ¹/₂gt²,
Using the given values, we find that,
V₀ = √(2 x 32.17 x 190) = 110.56 ft/s.
Substituting this value and the value of g into the equation of motion for the vertical direction, we get -190 = 110.56t - ¹/₂(32.17)t², which simplifies to 16.0850t² - 110.560t - 190 = 0.
The equation for the horizontal motion of the ball is given by [tex]x = V_xt[/tex], where x is the horizontal distance traveled, Vx is the initial horizontal velocity, and t is the time. Using the given value of x, we can find Vx as [tex]V_x = 440/t.[/tex]
We can then solve the quadratic equation 16.0850t² - 110.560t - 190 = 0 to find the time t of flight.
Using the formula method, we get t = 8.3 s. Substituting this value into the equation for the horizontal motion, we get [tex]V_x = 440/8.3 = 53.01 ft/s.[/tex]
Finally, we can find the angle of projection θ using the formula tan θ = [tex](V_y) / (V_x)[/tex],
tan θ = (110.56)/(53.01),
which simplifies to tan θ = 2.086. Taking the inverse tangent of both sides, we get θ = tan⁻¹(2.086) = 64.4⁰.
Therefore, the angle at which the ball takes off is 64.4⁰.

Reflection across the x-axis
Reflection across x = 6
Reflection across y = −3
Reflection across the y-axis
Answer:
The question is asking about the line of reflection that would transform polygon ABCDE to its image A' B' C' D' E'.
To determine the line of reflection, we need to identify the axis or line that reflects each point of polygon ABCDE to its corresponding point on polygon A' B' C' D' E'.
Looking at the coordinates of the vertices, we can see that the x-coordinates of the corresponding points are the same, but the y-coordinates are opposite in sign. This suggests that the line of reflection is parallel to the x-axis.
Furthermore, we can see that the reflected image is below the original polygon, so the line of reflection must be the x-axis itself, reflecting the polygon downward.
Therefore, the correct answer is "Reflection across the x-axis."

Determine how many liters a right circular cylindrical tank holds if it is 5 m long and 13 m in diameter.
The tank holds about _____ liters of liquid.
(Round to the nearest thousand as needed.)
The right circular cylindrical tank which is 5 m long and 13 m in diameter holds about 663,325 liters of liquid approximately.
The formula to find the volume of a right cylindrical tank is
V = πr²h, where 'r' is the radius and 'h' is the height.
Given that, the height is 5 m and the diameter is 13 m.
Radius = Diameter/2.
Radius = 13/2 = 6.5 m.
We know that, π = 3.14.
Now, we can substitute the values in the formula.
V = 3.14×(6.5)²×5.
V = 3.14×6.5×6.5×5
V = 663.325 cubic meters.
Now, we have to convert cubic meters into liters.
We need to multiply by 1000 as a thousand liters are in one cubic meter.
663.325×1000 = 663,325.

Compare and contrast the direct write-off method and the allowance method for bad debts.
At a minimum, please consider the following in your answer:
When is the expense for uncollected accounts receivable recognized under each method?
Why is the direct write-off method not considered to follow generally accepted accounting
The direct write-off method and the allowance method are two different ways of accounting for uncollectible accounts receivable.
How do we explain?When an account is found to be uncollectible, the direct write-off method records the expense for uncollected accounts receivable. This approach involves simply writing off the uncollectible account as a bad debt expense and deducting the outstanding quantity from the accounts receivable total.
Despite being quite easy to understand and basic, this method does not adhere to generally accepted accounting principles (GAAP) because it does not match expenses to the time period during which income was generated.
In contrast, the allowance approach establishes an allowance for doubtful accounts contra-asset account and estimates the amount of uncollectible accounts before recognizing the expense for uncollected accounts receivable.
This allowance account is used to lower the balance of accounts receivable to the anticipated amount of collection. Instead of when the account is found to be uncollectible, the expense is recognized at the time the estimate is made. Because it matches the expense to the time period in which the revenue was received, this method is thought to be more accurate than the direct write-off method.

The medical requirements for the treatment are:
• The dose (in ng/ml) may not exceed 100 at any time.
• The dose must fall to be at or below 20 ng/ml by 24 hours.
Within these parameters, the treatment effect will be measured in ng/ml-hours. (1

3. For the Delay Type and dosage level you selected above,
(a) determine the treatment effect over the first 24 hours.
(b) determine the residual treatment effect for time after the first 24 hours
We can calculate the residual treatment effect for a time after the first 24 hours by adding up the integrals for each subsequent 24-hour period until the residual treatment effect falls to or below 20 ng/ml
How to solveTo determine the optimal dosage amount A for each Delay Type, we need to first define the surge function for each delay type as:
Extended: f(t) = [tex]At^2e^-^0^.^3^t[/tex]
Medium: f(t) = [tex]At^3e^-^0^.^5^t[/tex]
Rapid: f(t) = [tex]At^3e^-^0^.^7^t[/tex]
To find the optimal dosage amount A, we need to maximize the treatment effect while ensuring that the dose does not exceed 100ng/ml at any time and falls to be at or below 20ng/ml by 24 hours.
The treatment effect can be calculated by integrating the surge function over time from 0 to 24 hours and then adding up the integrals for each subsequent 24-hour period until the residual treatment effect falls to or below 20ng/ml
For the Delay Type and dosage level selected, we can calculate the treatment effect over the first 24 hours by integrating the surge function from 0 to 24 hours.
Then, we can calculate the residual treatment effect for a time after the first 24 hours by adding up the integrals for each subsequent 24-hour period until the residual treatment effect falls to or below 20 ng/ml..

An individual depositing in a non-IRA account has to pay income taxes on the funds deposited and on interest earned in each year but does not have to pay taxes on withdrawals from the account.
Sarah, who is five years from retirement, receives a $10,000 bonus at work. She is trying to decide whether to save this extra income in an IRA account or in a regular savings account. Both accounts earn 8 percent nominal interest, and Sarah is in the 30 percent tax bracket in every year (including her retirement year)
If Sarah invests in the normal savings account, her net value (after taxes) five years from now will be?:
The net value of the $10,000 bonus in a normal savings account after taxes and interest in five years will be $9,181.
What is the net value of Sarah's $10,000 bonus in a normal savings account after taxes and interest in five years?Assuming an 8 percent nominal interest rate and a 30 percent tax bracket, the after-tax return on the normal savings account is 5.6 percent. Thus, after five years, the $10,000 bonus will grow to $14,693.
However, since Sarah is in the 30 percent tax bracket in every year, she will owe taxes on the interest income earned each year. This reduces the after-tax return to 3.92 percent. Therefore, in five years, the $10,000 bonus in the normal savings account will be worth $9,181 after taxes.
