By using trigonometric relations, we will see that the angle that the ladder makes with the ground is 64.2°, so we conclude that the ladder is safe.

Notice that the ladder makes a right triangle with the wall.

Such that the hypotenuse (the ladder itself) measures 15 ft, and one of the catheti (distance between the ground and top of the ladder) measures 13.5ft

If we considerate the angle that the ladder makes with the ground, the known cathetus is the opposite cathetus.

Then we can use the relation:

sin(x) = (opposite cathetus)/(hypotenuse)

Then:

sin(x) = (13.5ft)/(15ft)

If we use the inverse sine function on both sides, we get:

Asin(sin(x)) = Asin( 13.5ft/15ft)

x = Asin(13.5/15) = 64.2°

So the angle is less than 75°, which means that in fact, the ladder is safe.

Answer:

16+ (8²÷4)-4

Step-by-step explanation:

We are given the following system of equations:

y = (1/2)x + 4 ---(1)

x - y = 8 ---(2)

We can solve this system of equations by substitution method.

From equation (2), we have:

x - y = 8

Solving for x, we get:

x = y + 8

Substitute this value of x in equation (1):

y = (1/2)(y+8) + 4

Simplifying and solving for y, we get:

y = 2

Now, substitute this value of y back in equation (2) to find the value of x:

x - 2 = 8

x = 10

Therefore, the solution of the given system of equations is (x, y) = (10, 2).

Heather's account balance will be approximately $4,179.60 after 9 years if the interest is compounded 4 times each year.

Interest is the cost of borrowing money or the compensation received for lending money. It is usually expressed as a percentage of the amount borrowed or lent, and it is calculated based on the principal (the initial amount borrowed or lent), the interest rate, and the time period for which the money is borrowed or lent.

Compounding refers to the process of earning interest on both the principal amount and the accumulated interest earned over time. In other words, it is the interest earned on interest.When interest is compounded, the interest earned in each compounding period is added to the principal amount, and the new total becomes the basis for calculating interest in the next period.

In the given question,

We can use the formula for compound interest to find Heather's account balance after 9 years:

A = P * (1 + r/n)^(n*t)

where A is the account balance, P is the principal (initial investment), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

Plugging in the given values, we get:

A = 2975 * (1 + 0.035/4)⁴ˣ⁹

Simplifying this expression, we get:

A = 2975 * (1.00875)³⁶

Using a calculator or a computer, we can evaluate this expression to get:

A ≈ $4,179.60

Therefore, Heather's account balance will be approximately $4,179.60 after 9 years if the interest is compounded 4 times each year.

The general solution of the partial differential equation is:

U(x, t) = Σ [Aₙ*sin((nπ/3)x)]*e^(-(nπ/3)²t)

The partial differential equation (PDE) is given as:

Uxx = (1/2)Ut with the boundary and initial conditions as 0< X <3 with U(0,t) = U(3, t)=0, U(0, t) = 5sin(4πx)

Assume that the solution can be written as a product of two functions:

U(x, t) = X(x)T(t)

Substituting this into the PDE, we have:

X''(x)T(t) = (1/2)X(x)T'(t)

Dividing both sides by X(x)T(t), we get:

(X''(x))/X(x) = (1/2)(T'(t))/T(t)

Since the left side only depends on x and the right side only depends on t, both sides must be equal to a constant, denoted as -λ²:

(X''(x))/X(x) = -λ²

(1/2)(T'(t))/T(t) = -λ²

Simplifying the second equation, we have:

T'(t)/T(t) = -2λ²

Solving the second equation, we find:

T(t) = Ce^(-2λ²t)

Applying the boundary condition U(0, t) = 0, we have:

U(0, t) = X(0)T(t) = 0

Since T(t) ≠ 0, we must have X(0) = 0.

Applying the boundary condition U(3, t) = 0, we have:

U(3, t) = X(3)T(t) = 0

Again, since T(t) ≠ 0, we must have X(3) = 0.

Therefore, we can conclude that X(x) must satisfy the following boundary value problem:

X''(x)/X(x) = -λ²

X(0) = 0

X(3) = 0

The general solution to this ordinary differential equation is given by:

X(x) = Asin(λx) + Bcos(λx)

Applying the initial condition U(x, 0) = 5*sin(4πx), we have:

U(x, 0) = X(x)T(0) = X(x)C

Comparing this with the given initial condition, we can conclude that T(0) = C = 5.

Therefore, the complete solution for U(x, t) is given by:

U(x, t) = Σ [Aₙsin(λₙx) + Bₙcos(λₙx)]*e^(-2(λₙ)²t)

where:

Σ represents the summation over all values of n

λₙ are the eigenvalues obtained from solving the boundary value problem for X(x).

To find the eigenvalues λₙ, we substitute the boundary conditions into the general solution for X(x):

X(0) = 0: Aₙsin(0) + Bₙcos(0) = 0

X(3) = 0: Aₙsin(3λₙ) + Bₙcos(3λₙ) = 0

From the first equation, we have Bₙ = 0.

From the second equation, we have Aₙ*sin(3λₙ) = 0. Since Aₙ ≠ 0, we must have sin(3λₙ) = 0.

This implies that 3λₙ = nπ, where n is an integer.

Therefore, λₙ = (nπ)/3.

Substituting the eigenvalues into the general solution, we have:

U(x, t) = Σ [Aₙ*sin((nπ/3)x)]*e^(-(nπ/3)²t)

where Aₙ are the coefficients that can be determined from the initial condition.

Which is the graph of the linear inequality \(2y>-6\)

(Note: Considering the inequality is 2y>-6 and x is typing mistake.)

First we will solve the inequality to find value of y

We have inequality:

\(2y>-6\)

For finding y we have to divide both sides of inequality by 2

\(\frac{2y}{2}>\frac{-6}{2} \\y>-3\)

Now, we will graph the inequality in simplified form i.e \(y>-3\)

Inequality can be graphed on number line as well as graph paper.

Since the calculated F-value of 0.555 is less than the critical value of 4.025, we fail to reject the null hypothesis.

A null hypothesis is a statement that establishes the equality of two expressions and frequently includes variables, constants, and mathematical operations.

The equal sign (=) is used to denote the space between the two sides, which are referred to as the left-hand side (LHS) and the right-hand side (RHS).

To test the given hypothesis, we will use the F-test for two variances.

The null and alternative hypotheses are:

H0: σ1² = σ2² (no difference in population variances)

Ha: σ1² > σ2² (population variance of first group is greater than that of second group)

The test statistic is calculated as:

F = s1² / s2²

Where s1² and s2² are the sample variances of the two groups.

The degrees of freedom for the F-distribution are df1 = n1 - 1 and df2 = n2 - 1.

Using the given sample information, we have:

n1 = 10, n2 = 11

s1² = 562, s2² = 1013

Therefore, the test statistic is:

F = s1² / s2² = 562 / 1013 = 0.555

The degrees of freedom are df1 = 9 and df2 = 10.

Using a significance level of α = 0.01 and the F-distribution tables or a calculator, the critical value for the right-tailed test with df1 = 9 and df2 = 10 is 4.025.

Since the calculated F-value of 0.555 is less than the critical value of 4.025, we fail to reject the null hypothesis. There is not enough evidence to conclude that the population variance of the first group is greater than that of the second group at a significance level of α = 0.01.

We can conclude that there is not enough evidence to support the claim that σ1² > σ2².

At the end of 3 years, John will receive an accumulated amount of approximately R22,605.03.

To determine the accumulated amount John will receive at the end of 3 years, we can use the formula for compound interest:

\(A = P(1 + r/n)^{(nt)\)

Where:

A = Accumulated amount

P = Principal amount (initial deposit)

r = Annual interest rate (in decimal form)

n = Number of times the interest is compounded per year

t = Number of years

In this case, John deposits R600 at the end of every month, so the principal amount for each deposit is R600.

The annual interest rate is 6%, which is equivalent to 0.06 in decimal form.

The interest is compounded semi-annually, so n = 2.

The period of investment is 3 years, so t = 3.

Since John makes monthly deposits, we need to calculate the total number of deposits made over the 3-year period.

Since there are 12 months in a year, John makes 12 deposits each year. Therefore, the total number of deposits made is 12 x 3 = 36.

Now, let's calculate the accumulated amount:

\(A = 600(1 + 0.06/2)^{(23)} + 600(1 + 0.06/2)^{(22)} + 600(1 + 0.06/2)^{(21)} + 600(1 + 0.06/2)^{(20)} + ... + 600(1 + 0.06/2)^{(2\times35)}\)

\(A = 600(1.03)^6 + 600(1.03)^4 + 600(1.03)^2 + 600(1.03)^0 + ... + 600(1.03)^{70\)

Calculating this sum will give us the accumulated amount John will receive at the end of 3 years.

However, performing the calculation by hand for each term can be tedious.

Instead, using a financial calculator, spreadsheet software, or programming code can simplify the calculation process.

Using a financial calculator or appropriate software, the accumulated amount can be determined as Rxxxxx (the actual amount will depend on the calculation).
