Answer: The journal entry to record the addition of $500 to the Allowance for Doubtful Accounts account would be:

Debit Allowance for Doubtful Accounts account: $500

Credit Bad Debt Expense account: $500

The resulting balance in the Allowance for Doubtful Accounts account would be $2,500.

Step-by-step explanation:

Yes, the previous balance in the Allowance for Doubtful Accounts account does come into play when you add $500 to the account. The Allowance for Doubtful Accounts account is a contra asset account that is used to offset the Accounts Receivable account. It represents an estimate of the amount of accounts receivable that are expected to be uncollectible.

The balance in the Allowance for Doubtful Accounts account is based on the estimated amount of uncollectible accounts, which is typically a percentage of the total accounts receivable balance. When you add $500 to the account, you are increasing the estimated amount of uncollectible accounts.

To record this journal entry, you would debit the Allowance for Doubtful Accounts account for $500 and credit an expense account (such as Bad Debt Expense) for the same amount. The previous balance of $2,000 would also be included in the account balance and would be reflected in the new balance of $2,500.

The journal entry to record the addition of $500 to the Allowance for Doubtful Accounts account would be:

Debit Allowance for Doubtful Accounts account: $500

Credit Bad Debt Expense account: $500

The resulting balance in the Allowance for Doubtful Accounts account would be $2,500.

The linear equation on the graph can be written as:

y = (3/4)*x - 1

Here we have the graph of a linear equation, these are written as:

y = mx + c

Where m is the slope and c is the y-intercept.

On the graph we can see that the line intercepts the y-axis at y = -1, then we can write:

c = -1

So the linear equation is:

y = mx - 1

Looking at the graph we can see that the line also passes through the point (4, 2).

Replacing that in the linear equation we will get:

2 = m*4 - 1

2 + 1 = m*4

3 = m*4

3/4 = m

Then the linear equation on the graph is:

y = (3/4)*x - 1

The length of line JC is 20 miles.

What is Pythagorean theorem?

The Pythagorean theorem is a fundamental concept in geometry that states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of sides of triangle.

To find the length of line JC, which is the hypotenuse of the right triangle JSC, we can use the Pythagorean theorem, which 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).

In this case, we have:

JS² + SC² = JC²

Substituting the given values, we get:

12² + 16² = JC²

144 + 256 = JC²

400 = JC²

Taking square root both sides, we get:

JC = √400

JC = 20

Answer:

Step-by-step explanation:

The discriminant value (denoted by Δ) of a quadratic equation in the form of ax² + bx + c = 0 is given by the expression b² - 4ac.

For the quadratic equation m² + 18m + 17 = 0, a = 1, b = 18, and c = 17. Substituting these values into the expression for the discriminant, we get:

Δ = b² - 4ac

Δ = (18)² - 4(1)(17)

Δ = 324 - 68

Δ = 256

Therefore, the discriminant value of the quadratic equation m² + 18m + 17 = 0 is 256.

The slope of the function is -29 and the y-intercept is the point (0, 2).

What is function ?

In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. It is a rule that assigns to each element of a set (called the domain) exactly one element of another set (called the range).

To find the slope and y-intercept of the function p(x) = 2 - 29x, we can write it in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

So, by comparing p(x) = 2 - 29x with y = mx + b, we can see that:

m = -29 (the coefficient of x)

b = 2 (the constant term)

Therefore, the slope of the function is -29 and the y-intercept is the point (0, 2).

Answer:

The value of sin^-1(-3√2) is an angle whose sine is -3√2.

Since the sine function is an odd function, sin(-θ) = -sin(θ), we can find the reference angle by taking the inverse sine of the positive value 3√2, which gives:

sin^-1(3√2) ≈ 80.06°

The sine function is also negative in the third and fourth quadrants of the unit circle. Since the given value is negative, the angle must lie in either the third or fourth quadrant.

To determine in which quadrant the angle lies, we can use the fact that sine is negative in the third and fourth quadrants. Since sin^-1(-3√2) gives a positive value, the angle must lie in the third quadrant where the sine is negative.

Therefore, sin^-1(-3√2) = -80.06° (rounded to two decimal places).

Answer:

The probability that a randomly selected member of the labor force is Asian given that he or she is unemployed is 4.98%

Step-by-step explanation:

We want to find the probability that a randomly selected member of the labor force is Asian given that he or she is unemployed, which can be written as P(A|U). Using Bayes' theorem, we have:

P(A|U) = P(U|A) * P(A) / P(U)

We are given P(A) = 0.06 (6% of the labor force is Asian), P(U|A) = 0.05 (among Asians in the labor force, 5% are unemployed), and P(U|not A) = 0.06 (among non-Asians in the labor force, 6% are unemployed).

To find P(U), we can use the law of total probability:

P(U) = P(U|A) * P(A) + P(U|not A) * P(not A)

We know P(A) = 0.06, so P(not A) = 1 - P(A) = 0.94.

Therefore,

P(U) = 0.05 * 0.06 + 0.06 * 0.94 = 0.0602

Now we can substitute all the values into Bayes' theorem:

P(A|U) = 0.05 * 0.06 / 0.0602 = 0.0498

So the probability that a randomly selected member of the labor force is Asian given that he or she is unemployed is 4.98% (rounded to the nearest percentage with no decimal places).

The hypothesis is that at least 1 out of 5 drills will strike oil. Based on the results from the simulation trials, the hypothesis should be rejected.

Answer:

We can use the simple interest formula to find the rate of interest that the town savings bank pays:

Simple Interest = Principal x Rate x Time

where Principal is the initial deposit, Rate is the interest rate, and Time is the time period.

We know that the Principal is $5000, the Simple Interest earned over the first 10 years is $2950, and the Time is 10 years. Substituting these values into the formula, we get:

$2950 = $5000 x Rate x 10

Simplifying the equation, we get:

Rate = $2950 / ($5000 x 10)

Rate = 0.059 or 5.9%

Therefore, the town savings bank pays an interest rate of 5.9% on its savings accounts.

The percentage decrease in total principal and interest paid between a 30-year term mortgage and a 15-year mortgage with an APR of 6.5% and a principal balance of $242,300.00 is about 31.1%

An APR is an acronym for the Annual Percentage Rate, which is the interest on al loan amount expressed as a percentage of the amount on loan annually.

The loan amount, the annual percentage rate, and the term of the loan are presented as follows;

Loan amount, P = $242,300.00

Term of the loan, t = 30 years and 15 years

Annual Percentage Rate (APR), r = 6.5%

The amount of the loan after the period can be obtained by using the formula;

A = P·(1 + r)^t

The amount of each loan can therefore be calculated as follows;

The monthly payment is; M = P·(r·(1 + r)^t)/((1 + r)^t - 1)

M = 242,300×((0.065/12) × (1 + (0.065/12))^(30×12))/((1 + ((0.065/12)))^(30×12) - 1) ≈ 1531.5

The total payment on the 30-year loan ≈ 360 × 1531.5 = 551,340

The monthly payment for the 15-year loan is therefore;

M = 242,300×((0.065/12) × (1 + (0.065/12))^(15×12))/((1 + ((0.065/12)))^(15×12) - 1) ≈ 2110.7

The total payment on the 15-year loan ≈ 360 × 2110.7 = 379962

551,340

The percentage change is therefore;

((551,340 - 379962)/551,340) × 100 ≈ 31.1%

The percentage decrease in the total principal and interest paid between the 30-year term mortgage and a 15-year mortgage is about 31.1%

Answer:

Step-by-step explanation:

To find the maximum height of the ball, we need to find the vertex of the parabolic function h(t) = -t^2 + 8t + 32. The vertex represents the highest point of the parabolic curve.

The x-coordinate of the vertex is given by the formula x = -b/2a, where a and b are the coefficients of the quadratic equation. In this case, a = -1 and b = 8, so we have:

x = -b/2a = -8/(2(-1)) = 4

Therefore, the vertex occurs at time t = 4.

To find the y-coordinate of the vertex, we evaluate the function at t = 4:

h(4) = -4^2 + 8(4) + 32 = 16 + 32 = 48

Therefore, the ball reaches a maximum height of 48 feet above the ground.

Answer:

a)  Area of inner square = 58 cm²

b)  Area of inner square = (2x² - 2xy + y²) cm²

Step-by-step explanation:

To calculate the area of a square, multiply the length of one of its sides by itself. This can be expressed as A = s², where A is the area and s is the side length of the square.

To calculate the area of a triangle, halve the product of its base and height. This can be expressed as A = (1/2)bh, where A is the area, b is the base and h is the height of the triangle.

The easiest way to calculate the area of the inner square is to subtract the areas of the 4 congruent triangles from the area of the outer square.

[tex]\hrulefill[/tex]

The outer square has a side length of 10 cm. Therefore its area is:

[tex]\implies \sf A_{outer\;square} = 10^2 = 100 \; cm^2[/tex]

Each corner triangle has a height of 3 cm and a length of (10 - 3) cm.

Therefore, the area of one triangle is:

[tex]\implies \sf A_{triangle}=\dfrac{1}{2} \cdot 7 \cdot 3=10.5\;cm^2[/tex]

Therefore, the area of the inner square is:

[tex]\begin{aligned} \implies \sf Area\;of\;inner\;square&=\sf 100-(4 \cdot 10.5)\\&=\sf 100-42\\&=\sf 58\; cm^2\end{aligned}[/tex]

[tex]\hrulefill[/tex]

The outer square has a side length of y cm. Therefore its area is:

[tex]\implies \textsf{A$_{\sf outer\;square}$} = y^2 \; \sf cm^2[/tex]

Each corner triangle has a height of x cm and a length of (y - x) cm.

Therefore, the area of one triangle is:

[tex]\begin{aligned}\implies \sf A_{triangle}&=\dfrac{1}{2} \cdot (y-x) \cdot x\\\\&=\dfrac{1}{2}x(y-x)\;\sf cm^2\end{aligned}[/tex]

Therefore, the area of the inner square is:

[tex]\begin{aligned} \implies \sf Area\;of\;inner\;square&=y^2-4\left(\dfrac{1}{2}x(y-x)\right)\\\\&=y^2-2x(y-x)\\\\&=y^2-2xy+2x^2\\\\&=(2x^2-2xy+y^2)\; \sf cm^2\end{aligned}[/tex]
