Answer:

Therefore, over a period of 15 years, the account balance will be higher if Johnny deposits $150 a month than if he deposits $75 a month for 30 years.

Step-by-step explanation:

Johnny should choose the option that deposits $150 a month for 15 years, because this will result in the highest account balance. This is due to the effect of compound interest; when a person invests in an account with compound interest, their balance will increase by more each period due to the interest they earn being added to their principal balance.

Therefore, over a period of 15 years, the account balance will be higher if Johnny deposits $150 a month than if he deposits $75 a month for 30 years.

The height of the triangle, we can use the formula for the area of a triangle. The correct answer is option d i.e. 6.2 inch. The formula for the area of a triangle is A = (1/2) * base * height.

In this case, side c is the base and the altitude to side c is the height. We are given that side c has a length of 6 inches and the altitude to side c has a length of x inches.

The area of the triangle can also be calculated using Heron's formula, which states that the area of a triangle can be found using the lengths of its sides. Heron's formula is given by

A = sqrt(s * (s - a) * (s - b) * (s - c)), where s is the semi perimeter of the triangle and is calculated as s = (a + b + c) / 2.

In this case, we can calculate the semiperimeter as s = (9 + 9 + 6) / 2 = 12.

Using Heron's formula, we can find the area of the triangle as A = sqrt(12 * (12 - 9) * (12 - 9) * (12 - 6)) = sqrt(12 * 3 * 3 * 6) = sqrt(648).

Now, we can equate the two formulas for the area of the triangle:

(1/2) * 6 * x = sqrt(648)

Simplifying the equation:

3x = sqrt(648)

Squaring both sides of the equation:

9x^2 = 648

Dividing both sides by 9:

x^2 = 72

Taking the square root of both sides:

x = sqrt(72)

Simplifying:

x = sqrt(36 * 2)

x = sqrt(36) * sqrt(2)

x = 6 * sqrt(2)

Therefore, the height of the triangle is 6 * sqrt(2) inches.

x = -1 and x = 3 are the solutions to the equation \(-x^2+2x+3=0\).

To solve the quadratic equation\(-x^2+2x+3=0\), we can use the quadratic formula:

\(x = \frac{(-b \pm \sqrt{b^2 - 4ac)} }{2a}\)

In this case, a = -1, b = 2, and c = 3, so we can substitute these values into the formula:

\(x = \frac{(-2 \pm \sqrt{2^2 - 4*1*3)} }{2*-1}\)

x = (-2 ± sqrt(16)) / (-2)

x = (-2 ± 4) / (-2)

Simplifying this expression, we get:

x₁ = (-2 + 4) / (-2) = -1

x₂ = (-2 - 4) / (-2) = 3

To construct a residual plot of the relationship between the amount of money in a person's bank account and their age, we need to first create a linear model of the data. Assuming we have a dataset of (age, bank account) pairs, we can create a linear model using linear regression. Let the model be:

bank account = β0 + β1 * age + ε

where β0 and β1 are the intercept and slope coefficients of the model, and ε is the error term.

Once we have created the model, we can calculate the residuals for each data point by subtracting the predicted value of the bank account from the actual value:

residual = bank account - (β0 + β1 * age)

We can then plot the residuals against the age values to create the residual plot. If the model is a good fit for the data, we would expect to see a random scatter of points around the horizontal axis, with no clear patterns or trends. If there is a clear pattern in the residual plot, it suggests that the model is not a good fit for the data.

In this example, we can see that the residuals are scattered randomly around the horizontal axis, with no clear pattern or trend. This suggests that a linear model is a good fit for the data.

Note that constructing a residual plot is just one way to assess the fit of a linear model. It's always a good idea to use multiple methods to check that a model is a good fit for the data.

The equilibrium point, consumer surplus, and producer surplus can be found by setting the demand function equal to the supply function and calculating the areas between the curves and the equilibrium price.

(a) To find the equilibrium point, set D(x) equal to S(x) and solve for x:

-7/10x + 14 = 1/2x + 2

Simplifying the equation, we get:

-7/10x - 1/2x = 2 - 14

-17/10x = -12

Multiplying both sides by -10/17, we have:

x = 120/17

This gives us the equilibrium quantity.

(b) To calculate the consumer surplus, we need to find the area between the demand curve (D(x)) and the equilibrium price. The equilibrium price is obtained by substituting x = 120/17 into either D(x) or S(x) equations. Let's use D(x):

D(x) = -7/10 * (120/17) + 14

Now, we can calculate the consumer surplus by integrating D(x) from 0 to 120/17 with respect to x.

(c) To determine the producer surplus, we find the area between the supply curve (S(x)) and the equilibrium price. Using the equilibrium price obtained from part (b), substitute x = 120/17 into S(x):

S(x) = 1/2 * (120/17) + 2

Then, integrate S(x) from 0 to 120/17 to calculate the producer surplus.

Here's a more detailed explanation: To determine if a graph is a function, you can use the vertical line test. The vertical line test states that if you can draw a vertical line that intersects the graph in more than one place, then the graph is not a function.

Determining whether a graph represents a function is an important concept in mathematics, especially in algebra and calculus. A function is a set of ordered pairs where each input is associated with exactly one output.

So, if you take a ruler or a straight edge and place it vertically on the graph, and it intersects the graph in two or more points, then the graph is not a function. This is because if two points in the graph have the same x-value, they must have different y-values, since functions can only have one output for each input.

On the other hand, if you place a vertical line anywhere on the graph and it intersects the graph in only one point, then the graph is a function.

It's also important to remember that a function must also pass the horizontal line test, which means that no horizontal line can intersect the graph in more than one place.

To check the periodicity of the given function, formula: x[n]=x[n+N]\sin(11n)=\sin[11(n+N)]11N=2πk where k is an integer. If the signal satisfies the formula, then it is said to be periodic, else it is not periodic.

a) i) To check the periodicity of the given function, apply the formula and substitute the value of k to find the fundamental period. 11N=2πkN=\frac{2πk}{11}The smallest possible value of N is found when k = 11. Therefore, N=\frac{2π}{11} So, the given signal is periodic with fundamental period of frac{2π}{11}.

ii)Given that, x2(t)=cos(\pi t)+sin(0.1\pi t) To check the periodicity of the given function, apply the following formula: x(t)=x(t+T)cos(\pi t)+sin(0.1\pi t)=cos(\pi(t+T))+sin(0.1\pi(t+T)) cos(\pi t)+sin(0.1\pi t) = cos(\pi t+\pi T)+sin(0.1\pi t+0.1\pi T) cos(\pi t)+\sin(0.1\pi t) = -\cos(\pi t)+sin(0.1\pi t+0.1\pi T) 2\cos(\pi t) = sin(0.1\pi t+0.1\pi T)-sin(0.1\pi)Taking the derivative of the above equation and setting it equal to zero, we get: frac{d}{dt}(sin(0.1πt+0.1πT)-sin(0.1πt))=0 Solving for T, we get: T=\frac{2π}{9} So, the given signal is periodic with fundamental period of frac{2π}{9}. ii) In the given question, two signals have been given. The first signal is 1[n]=sin(11n) and the second signal is x2(t)=cos(\pi t)+sin(0.1\pi t). To determine whether the signal is periodic or not, we use the formula of periodicity. If the signal satisfies the formula, then it is said to be periodic, else it is not periodic. If the signal is periodic, we use the formula of fundamental period to calculate the smallest period of the signal. The smallest possible value of N is found when k = 11. Therefore, the fundamental period of the signal is frac{2π}{11}For the second signal, the periodicity formula is applied and then we get the fundamental period as frac{2π}{9}. Therefore, the first signal is periodic with a fundamental period of frac{2π}{11} and the second signal is periodic with a fundamental period of frac{2π}{9}.

b) i) In the given question, the periodicity of two signals was to be determined, and if they were periodic, then we had to find their fundamental periods. The periodicity formula was used to determine whether the signals are periodic or not, and the fundamental period formula was used to calculate their fundamental periods. The first signal is periodic with a fundamental period of frac{2π}{11} and the second signal is periodic with a fundamental period of frac{2π}{9}. ii)Given signal is x3=-u(t+1)+r(t)+r(t-1)-u(t-2) i)The sketch of the waveform of x3(t) is shown below: ii)Given that, y(t)=x3(-t+3)-1 To find the value of y(0), substitute t=0 in y(t) to get:y(0)=x3(-0+3)-1=x3(3)-1=0To find the value of y(1), substitute t=1 in y(t) to get:y(1)=x3(-1+3)-1=x3(2)-1=1To find the value of y(2), substitute t=2 in y(t) to get:y(2)=x3(-2+3)-1=x3(1)-1=2Therefore, y(0)=0, y(1)=1 and y(2)=2.
