An investor needs to deposit an amount on 1 January 2020 to purchase an annuity to receive a series of payment on a regular basis, the present value of annuity B on 1 January 2020 is approximately RM 22,116.48.
To calculate the existing values of annuity A and annuity B on 1 January 2020, we can use the components for the present cost of an regular annuity:
PV = PMT * (1 - \((1 + r)^{(-n)\)) / r
For annuity A:
PMT = RM 2500
r = 8% compounded semiannually
n = 8
Using those values in the components, we are able to calculate the present cost for annuity A:
PV(A) = 2500 * (1 - \((1 + 0.08/2)^{(-8)\)) / (0.08/2)
≈ 2500 * (1 - \((1.04)^{(-8)\)) / 0.04
≈ 2500 * (1 - 0.593848) / 0.04
≈ 2500 * 0.406152 / 0.04
≈ 10153.04
For annuity B:
PMT = RM 1300
r = 10% compounded quarterly
n = 16
PV(B) = 1300 * (1 - \((1 + 0.10/4)^{(-16)\)) / (0.10/4)
≈ 1300 * (1 - \((1.025)^{(-16)\)) / 0.025
≈ 1300 * (1 - 0.572044) / 0.025
≈ 1300 * 0.427956 / 0.025
≈ 22116.48
Hence, the present value of annuity A is RM 10,153.04, and the present value of annuity B is RM 22,116.48 on 1 January 2020.

Step-by-step explanation:
given the linear system y[n] = 0.25y[n-1] x[n] for n > 0 and y[-1]=0 system is described by the impulse response h[n] = [0.25]nu[n]. determine if the system is stable or not
The system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.
The stability of a linear system can be determined by analyzing the magnitude of its impulse response −
|h[n]| ≤ M for some finite M
In this case, the impulse response is h[n] = 0.25nu[n], where nu[n] is the unit step function. Since the magnitude of h[n] is 0.25 for all n, the system is stable since 0.25 is a finite number that is less than any M.
To summarize, the system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.

(Chapter 14) If f(x,y) has two local maximal, then f must have a local minimum.TrueFalse
It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.
For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

Step-by-step explanation:
Hey,
We know that the circumfrence is the perimetert of a full circle. If we want to find the perimeter of a semicircle all we have to do is find the circumfrence and then divide it by 2 since we want to know the perimeter of half the circle.
Circumfrence is equal to 2πr. Where r is the radius and since we know the radius we an solve for the circumfrence.
2(π)(1km)=2kmπ.
The problem tells us to use 3.14 for pi so let's multiply 2 by 3.14.

In the one-way ANOVA, the within-groups variance estimate is like _________ in two-way ANOVA. A. the row variance estimate B. the within-cells variance estimate C. the column variance estimate D. the interaction variance estimate
In the one-way ANOVA, the within-groups variance estimate is equivalent to the within-cells variance estimate in the two-way ANOVA.
Option B is right choice.
In the one-way ANOVA, the within-groups variance estimate is equivalent to the within-cells variance estimate in the two-way ANOVA.
This is because both types of variance estimates measure the variation within groups or cells of the independent variable(s).
In a one-way ANOVA, the independent variable has only one factor or level, and the within-groups variance estimate measures the variation within each group or level of the factor.
This estimate reflects the extent to which the data points within each group deviate from the group mean.
In a two-way ANOVA, there are two independent variables or factors, and the within-cells variance estimate measures the variation within each combination of levels of the two factors.
This estimate reflects the extent to which the data points within each cell (or combination of factor levels) deviate from the mean of that cell.
Therefore, the within-cells variance estimate in the two-way ANOVA plays a similar role as the within-groups variance estimate in the one-way ANOVA.
Both estimates reflect the degree of variability within the groups or cells of the independent variable(s) and both are used to calculate the F-statistic and determine the statistical significance of the effects of the independent variable(s) on the dependent variable.
Option B is right choice.

What is a quadratic equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0)
f(x) = x^2 -2x +3 and f(x) = -2x + 12
which means
x^2 -2x +3 = -2x + 12
x^2 -2x +3 + 2x - 12 = 0
x^2 -9 = 0

(x-3)(x+3) = 0
x = 3 or -3
when x = 3
f(x) = -2x + 12
f(3) = -2(3) + 12 which is 6
when x = -3
f(-3) = -2(-3) + 12 which is 18

Given a composite figure which is shown in the question.
The area of a shape (in square units) is the number of unit squares required to cover the entire area without gaps or overlaps. If a hologram has planes, those faces are called faces. Area is the sum of the areas of the faces.
Firstly, we will find the area of front and end triangles by using the formula
Area=(1/2)×b×h and we will multiply this area by 2 because we are finding the area of two same triangles.
Here, h=6 and b=16 and substitute these values in the formula, we get
A₁=2×(1/2)×16×6
A₁=2×8×6
A₁=96m²
Now, we will find the area of the left and right side rectangles which joined both the triangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=10 and b=5 and substitute these values in the formula, we get
A₂=2×10×5
A₂=100m²
Further, we will find the area of the front and end side rectangles that joined both by the base of the triangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=16 and b=4 and substitute these values in the formula, we get
A₃=2×16×4
A₃=128m²
Furthermore, we will find the area of the left and right side rectangles which joined by the front and end rectangles.
We will find the area by using the formula Area=l×b and we will multiply this area by 2 because we are finding the area of two same rectangles.
here, l=4 and b=5 and substitute these values in the formula, we get
A₄=2×4×5
A₄=40m²
Now, we will find the area of the base of the composite figure which is rectangle.
We will find the area by using the formula Area=l×b.
here, l=16 and b=5 and substitute these values in the formula, we get
A₅=16×5
A₅=80m²
So, the surface area of the given composite figure will be
Surface area=A₁+A₂+A₃+A₄+A₅
Surface area=96m²+100m²+128m²+40m²+80m²
Surface area=444m²

$9 x 3 = $27 adult Wilson tickets $9 x 2 = $18 adult Jackson tickets
$5 x 4 = $20 student Wilson tickets $5 x 6 = $30 student Jackson tickets
$20 + $27 = $47 Wilson tickets $18 + $30 = $48 Jackson tickets
$48 - $47 = $1
Answer:
a. $1
Step-by-step explanation:
To find the difference, calculate how much each family spent on tickets and then subtract the lower number from the higher number. I’ll start with the Wilson’s.
First, multiply the cost of the tickets by how many they bought.
$9*3 adult tickets=$27
$5*4 student tickets=$20
Then, add the values together to find the total cost.
$27+$20=$47
Now, let’s do the same for the Jackson’s.
$9*2 adult tickets=$18
$5*6 student tickets=$30
$18+$30=$48
Finally, subtract the Jackson’s total cost from the Wilson’s.
$48-$47=$1
The difference is $1.

Let's call that result equation 4.
Now focus on equation 3 and equation 4
equation 3 is -x+7y-6z = 2
equation 4 is -x+7y-6z = 5
Note how the left hand sides are identical, but the right hand sides are different. This means that we have an inconsistent system with no solutions. No matter what numbers we pick for x,y,z, there is no way to make all three given original equations to be true.
