The yield on a corporate bond is A = 9.14 %

Given data ,

Face value of the bond (FV) = $1000

Purchase price of the bond = $850

Fixed interest rate = 8%

The annual interest payment (I) can be calculated as a percentage of the face value:

I = (Fixed interest rate / 100) * FV

Substituting the given values:

I = (8 / 100) x 1000 = $80

The yield (Y) can be calculated as:

Y = (Annual interest payment / Purchase price) * 100

Substituting the calculated values:

Y = (80 / 850) x 100 = 9.41%

Hence , the yield on the corporate bond is 9.41%

Answer:

  AB is not tangent to the circle

Step-by-step explanation:

You want to know if segment AB of length 9 is tangent to the circle with diameter 12 at point B given that the third side of the triangle is 13 units long.

You know that the numbers {5, 12, 13} are a Pythagorean triple, so these lengths form a right triangle. The lengths (9, 12, 13) cannot form a right triangle, so AB will not be perpendicular to the diameter.

AB is not a tangent

The segments will form a right triangle if they satisfy the Pythagorean theorem, which requires the sum of the squares of the shorter sides equal the square of the longest side.

  9² +12² = 13²

  81 +144 = 169 . . . . . . false — not a right triangle

A "form factor" can be computed for the triangle to tell if the largest angle is acute, right, or obtuse. That is ...

  f = a² +b² -c²

  f = 81 +144 -169 = 56 . . . . . . . f > 0 means the triangle is acute

The measure of the largest angle can be found from ...

  C = arccos(f/(2ab)) = arccos(56/216) ≈ 74.97°

This is further confirmation that AB is not tangent to the circle.

Additional comment

The attached drawing is to scale. It shows AB has two points of intersection with the circle, so is not tangent.

To solve this problem, we can use the formula for the future value of an annuity:

FV = PMT * ((1 + r)^n - 1) / r

where:

PMT = the monthly payment ($300)

r = the monthly interest rate (APR / 12 = 0.035 / 12 = 0.002917)

n = the number of months (18 years x 12 months/year = 216 months)

Plugging in the values, we get:

FV = 300 * ((1 + 0.002917)^216 - 1) / 0.002917

FV ≈ $77,300.31

Therefore, after 18 years of making monthly deposits of $300 into an investment plan with an APR of 3.5%, you will have approximately $77,300.31.

To compare this amount to the total deposits made over the time period, we can calculate the total deposits as:

Total deposits = PMT * n

Total deposits = $300 * 216

Total deposits = $64,800

We can see that the total deposits made over the 18-year period were $64,800, which is less than the final value of the investment of approximately $77,300. This is because of the effect of compound interest, where the interest earned on the investment is reinvested and earns additional interest over time, resulting in a higher final value.

Answer:

Step-by-step explanation:

To complete the sequence, we need to find the missing numbers that fit the pattern.

Looking at the given numbers, we can see that each number is obtained by adding a constant value to the previous number.

To find this constant value, we can calculate the differences between consecutive numbers in the sequence:

8 - 0 = 8

15 - 8 = 7

24 - 15 = 9

So the constant difference between consecutive terms in the sequence is not the same. Therefore, we can assume that this is not an arithmetic sequence.

However, we can observe that the sequence follows a pattern of adding increasing odd numbers to the previous term:

0 + 1 = 1

1 + 7 = 8

8 + 7 = 15

15 + 9 = 24

So the missing numbers in the sequence are 1 and 33.

Therefore, the completed sequence is:

0, 1, 8, 15, 24, 33.

It is true that the slope of the horizontal tangent line to the parametric curve at a point (x(t), y(t)) is given by dy/dx = (dy/dt)/(dx/dt).

The statement is saying that if f(g(t)) has a horizontal tangent at t = 1, then the curve has a well-defined tangent line at that point, which is also a horizontal tangent. Let's break this down step by step:

f(g'(1)) = 0: This means that the derivative of f with respect to its input g(t) is equal to zero at t = 1. In other words, the slope of the tangent line of f(g(t)) at t = 1 is zero.

dx/dt is not zero at t = 1: This means that the curve g(t) has a well-defined tangent line at t = 1, because the slope of the tangent line of g(t) is not infinite (i.e., the derivative dx/dt is defined and finite).

Setting dy/dx = 0 gives dy/dt / dx/dt = 0: This is using the chain rule of differentiation to relate the derivative of f with respect to t (i.e., dy/dt) to the derivative of f with respect to x (i.e., dy/dx) and the derivative of g with respect to t (i.e., dx/dt).

dy/dt = 0 when dx/dt is not zero: Since dy/dx = 0 and dx/dt is not zero, we can conclude that dy/dt must also be zero at t = 1. This means that the slope of the tangent line of f(g(t)) is also zero at t = 1.

Therefore, the curve has a horizontal tangent at t = 1: Since both g(t) and f(g(t)) have horizontal tangents at t = 1, we can conclude that the curve f(x) also has a horizontal tangent at x = g(1). This means that the tangent line to the curve at that point is horizontal.

The vertex is (-3,2) and the radius is 6 (sqr36).

To find the domain and range, note that their interval is on the vertical and horizontal diameter of the circle, fixed on a vertex point.

This means that the domain is the x value (-3) of the vertex + or - the radius (6): 3 and -9

Hence, domain is -9<=x<=3

Find the range using the same method: 8 and -4

Range is -4<=x<=8

Answer:

Standard equation =(x+3)²+(x-2)²=6²

Domain:     -9 ≤ x ≤ 3

Range:     -4 ≤ y ≤ 8  

Step-by-step explanation:

You need to put it in a format

(x-h)²+(y-k)²=r²  where (h,k) is your center

Equation:

x²+y²+6x-4y=23        rearrange the variables so x's and y's are together

x²+6x     +y²-4y      =23    complete the square for the quadratic by taking the middle term of each quadratic 6 and -4  

divide by 2 => [tex](\frac{6}{2} )^{2}[/tex] =9    and   [tex](\frac{-4}{2} )^{2} = 4[/tex]

add 9 and 4 to both sides

x² + 6x + 9 + y² - 4y + 4 = 23 +9+4     factor both of the quadratics

(x+3)(x+3) +(x-2)(x-2) = 36

(x+3)²+(x-2)²=36      now put it in form with radius

(x+3)²+(x-2)²=6²      (-3,2) center    and r=6

Standard equation =(x+3)²+(x-2)²=6²

Domain: we get that by where the circle starts and ends for x.  Since the radius is 6   and the center x point is -3

move left 6 from -3, that's your lower domain = -6-3=-9

move 6 right from center, that's your upper domain = -3+6 = 3

Domain:     -9 ≤ x ≤ 3  circle is between -9 and 3 in the x direction

Range: Now we do same for range but in y direction

Center y point is 2

move down 6 from 2 = -6+2 =-4, this is lower range

move up 6 from 2 = 2+6=8, this this is your upper range

Range:     -4 ≤ y ≤ 8   circle is between -4 and 8 for y direction

Rounded to two decimal places, the margin of error is 4.12 points. To find the margin of error for a 98% confidence interval, we'll use the formula:

Margin of Error = z-score * (population standard deviation / sqrt(sample size))

First, we need to find the z-score for a 98% confidence interval. Since the table provided shows two-tailed z-scores, we will look at the z0.01 column (1 - 0.98 = 0.02, and 0.02 / 2 = 0.01), which gives us a z-score of 2.576.

Next, we have the population standard deviation (8 points) and the sample size (25).

Now we can calculate the margin of error:

Margin of Error = 2.576 * (8 / sqrt(25))
Margin of Error = 2.576 * (8 / 5)
Margin of Error = 2.576 * 1.6

Margin of Error = 4.1216

The number of ways to choose an even number of right and left jumps can be calculated using the binomial coefficient. Specifically, the number of ways to choose k objects from a set of n objects is given by:

C(n, k) = n! / (k! * (n - k)!)

where n is the total number of objects and k is the number of objects chosen.

In this case, the frog must make a total of 3 jumps to reach a side of the square, so there are 2 possible values for the number of rights jumps it makes before it reaches the top or bottom of the square: 0 or 2. If the frog makes 0 right jumps, it must make 3 left jumps. If the frog makes 2 right jumps, it must make 1 left jump. The total number of possible sequences of jumps is:

C(3, 0) + C(3, 2) = 1 + 3 = 4

Out of these 4 possible sequences of jumps, only 2 of them end on a vertical side of the square. Specifically, the frog must make 2 left jumps and 1 right jump, or 2 right jumps and 1 left jump. Therefore, the probability that the frog ends on a vertical side of the square is:

Answer:

1/3πr²h

Step-by-step explanation:

The formulas for calculating the volume of a cylinder and a cone are:

Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

where r is the radius and h is the height of the shape.

Given that both shapes have a radius of 2 units and a height of 4 units, we can substitute these values into the formulas to calculate the volumes.

For the cylinder:

Volume of cylinder = πr²h

= π(2²)(4)

= 16π cubic units

Therefore, the volume of the cylinder is 16π cubic units.

For the cone:

Volume of cone = 1/3πr²h

= 1/3π(2²)(4)

= 8/3π cubic units

Therefore, the volume of the cone is 8/3π cubic units, which is approximately 8.38 cubic units (rounded to two decimal places).
