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.

Therefore, the tank holds about 663,325 liters of liquid approximately.

The direct write-off method and the allowance method are two different ways of accounting for uncollectible accounts receivable.

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 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.

There are 65,000 possible passwords of length 5 that can be made with no repeats allowed.

What is length?

Length is a measure of distance between two points or the extent of something along its longest dimension. It is one of the basic dimensions in geometry and can be defined as the distance between two points measured in one dimension, typically along a straight line.

Since at least one character must be a symbol, there are 5 choices for the first character. For the remaining four characters, there are 10 choices (0 to 9) for each character if digits are allowed, 26 choices (a to z) for each character if lowercase letters are allowed, and 5 choices for each character if the other symbols are allowed.

Therefore, the total number of passwords of length 5 that can be made, with no repeats allowed and at least one character being a symbol, is:

5 * (10 * 26 * 5 * 5 * 5)

Simplifying the expression, we get:

The volume of the rectangular prism is 13.125 cubic yards.

To find the number of cubes that fit along the length, width, and height of the rectangular prism, we need to divide the length, width, and height by the edge length of each cube, which is 1/2yd.

Along the length: (2 1/2 yd) / (1/2 yd) = 5 cubes

Along the width: (3 1/2 yd) / (1/2 yd) = 7 cubes

Along the height: (1 1/2 yd) / (1/2 yd) = 3 cubes

Therefore, there are 5 cubes along the length, 7 cubes along the width, and 3 cubes along the height of the rectangular prism.

To find the volume of the rectangular prism, we can multiply the length, width, and height:

Volume = (2 1/2 yd) x (3 1/2 yd) x (1 1/2 yd)

Volume = (5/2 yd) x (7/2 yd) x (3/2 yd)

Volume = (13.125 yd^3)

Thus, the perimeter of the shown triangle using the distance formula is found as  13.45 units.

A path that encircles a region is referred to as a perimeter. Adding the lengths of every one of the sides together is the simplest formula for calculating the perimeter. The word circumference, that only encompasses a circle's perimeter, is used to describe the distance around a circle.

Given that:

Perimeter = sum of all sides

Perimeter = AB + BC + CA

Estimate each distance using the distance formula:

d = √(x2 - x1)² + (y2 - y1)²

AB = √(1 - 5)² + (5 - 3)²

AB = √(-4)² + (-2)²

AB = √(16 + 4)

AB = √20

BC = √(3 - 1)² + (0 - 5)²

BC = √(2)² + (-5)²

BC = √(4 + 25)

BC = √29

CA = √(5 - 3)² + (3 - 0)²

CA = √(2)² + (3)²

CA =  √(4 + 9)

CA = √13

Perimeter = AB + BC + CA

Perimeter = √20 + √29 + √13

Perimeter = 4.47 + 5.38 + 3.60

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."

[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:

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:

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 equation of the ellipse is ((x+2)² / 36) + ((y-4)² / 35.12) = 1

To find the center of the ellipse, we can find the midpoint between the two vertices:

Midpoint = ((-8 + 4)/2, (4 + 4)/2) = (-2, 4)

So the center of the ellipse is (-2, 4).

To find the semi-major axis (a), we can find the distance from the center to one of the vertices:

Distance = √[(-8 - (-2))² + (4 - 4)²] = √36 = 6

So the semi-major axis is 6.

To find the distance between the foci (2c), we can find the distance between the two foci:

Distance = √[(-3 - (-1))² + (4 - 4)²] = 2

So 2c = 2 and c = 1.

Now we can use the relationship between a, b, and c in an ellipse:

c² = a²- b²

(1)² = (6)² - b²

b² = 35

b ≈ 5.92

So the semi-minor axis is approximately 5.92.

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.

By using compound interest formula, we conclude that Sophie deposited $16,638 (rounded to the nearest whole number) into the account.

Compound interest is a method of calculating interest on a principal amount of money, where the interest earned on the initial principal is added to the principal at the end of each compounding period (usually monthly, quarterly, or annually).

We can use the formula for compound interest to solve this problem. The formula is:

[tex]A = P(1 + r/n)^{(nt)[/tex]

Where:

A = the total amount in the account

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

We know the values for A, r, n, and t, so we can solve for P:

[tex]A = P(1 + r/n)^{(nt)[/tex]

[tex]22,099.87 = P(1 + 0.022/2)^{(2*13)[/tex]
