[tex]\frac{21}{670}[/tex]

Step-by-step explanation:

Assuming the equation is:

[tex]\frac{3}{5} * \frac{7}{2*67}[/tex]

The first thing you have to do is simplify:

2 * 67 = 134

[tex]\frac{3}{5} * \frac{7}{134}[/tex]

Multiply the numerators:

3 * 7 = 21

Then multiply the denominators:

5 * 134 = 670

Then simplify again:

The bond yield that comes closest to 7.75%, the  amount yield to maturity on an annual-pay bond, is 7.61%.

A. The bond yield that comes closest to 7.75%, the yield to maturity on an annual-pay bond, is 7.61%. A measure of return that considers the market parameters used to determine the return from an investment in a bond is called the bond-equivalent yield. It accounts for the time value of money, the coupon rate, and the current market rate to determine the yearly rate of return that would be generated if the bond were kept for a year. When comparing bonds with differing coupon rates and maturities, the bond-equivalent yield is utilised. It is a helpful tool for investors who want to compare various bonds and decide on their investments with knowledge.

The solution to the system of equations is (0.839, 1.129).

What is a graph ?

Graph can be defined as visual representation of the data through the given ordered pairs .

Given ,

The graph of a line passes through the points (0, 0.5) and (6, 5). A second i has the equation 5y = 7-6x.

The equation of the first line can be found using the two given points, using the slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept. To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values from the two points, we have:

m = (5 - 0.5) / (6 - 0) = 4.5 / 6 = 0.75

So the equation of the first line is:

y = 0.75x + 0.5

To find the solution to the system of equations, we need to find the point where the two lines intersect, which means finding the values of x and y that satisfy both equations. To do this, we can substitute the equation of the first line into the second equation:

5y = 7 - 6x

0.75x + 0.5 = 7 - 6x

Solving for x, we get:

7.75x = 6.5

x = 6.5 / 7.75 = 0.839

Substituting x back into either equation to find y, we get:

y = 0.75x + 0.5 = 0.75 * 0.839 + 0.5 = 0.629 + 0.5 = 1.129

So the solution to the system of equations is (0.839, 1.129).

Therefore, The solution to the system of equations is (0.839, 1.129).

The volume V of the solid obtained by rotating the region bounded by the given curves y = 2[tex]e^{-x}[/tex], y = 2, x = 4; about y = 4 is 256π.

The volume of the solid obtained by rotating the region bounded by the given curves about the line y=4 is given by

V = 2π ∫⁴₀ (4-2[tex]e^{-x}[/tex])² dx

We can calculate the integral using integration by parts.

Let u = 4-2[tex]e^{-x}[/tex]

⇒ du = 2d[tex]e^{-x}[/tex]

and dv = 2dx

⇒ v = x

So,

V = 2π ∫⁴₀ (4-2[tex]e^{-x}[/tex])² dx

 = 2π (x (4-2[tex]e^{-x}[/tex])²  - 0 (4-2[tex]e^{-x}[/tex]})²  - 2∫⁴₀ x d (4-2[tex]e^{-x}[/tex]))

 = 2π (2×4³ - 4∫⁴₀ x [tex]e^{-x}[/tex] dx)

Using integration by parts again

Let u = 4-2[tex]e^{-x}[/tex] ⇒ du = -2d[tex]e^{-x}[/tex]

and dv = xdx ⇒ v = x²/2

So,

V = 2π (2×4³ - 4∫⁴₀ x [tex]e^{-x}[/tex] dx)

 = 2π (2×4³ - 2×2∫⁴₀ x² [tex]e^{-x}[/tex] dx)

Again we can calculate the integral using integration by parts.

Let u = x² ⇒ du = 2xdx

and dv = [tex]e^{-x}[/tex] dx ⇒ v = -[tex]e^{-x}[/tex]

So,

V = 2π (2×4³ - 2×2∫⁴₀4 x^2 [tex]e^{-x}[/tex]} dx)

 = 2π (2 × 4³-2 × 2 × ([tex]-e^{-4}[/tex] + 2∫⁴₀  [tex]e^{-x}[/tex]dx))

 = 2π (2×4³ - 2×2 (1+4))

 = 2π (2×4³ - 16)

 = 2π (128-16)

 = 256π

Therefore, the volume V of the solid obtained by rotating the region bounded by the given curves y = 2[tex]e^{-x}[/tex], y = 2, x = 4; about y = 4 is 256π.

Answer: There are 8 11-year-old students and 22 12-year-old students in Liam's class.

Step-by-step explanation:

Let's call the number of 11-year-old students in class x. Then, the number of 12-year-old students in the class would be 30 - x.

The total number of years that the 11-year-old students represent is 11 * x.

The total number of years that the 12-year-old students represent is 12 * (30 - x).

The sum of all the years is 352, so we can set up an equation based on the above information:

11x + 12(30 - x) = 352

Expanding the second term on the left-hand side:

11x + 360 - 12x = 352

Combining like terms:

-x + 360 = 352

Subtracting 360 from both sides:

-x = -8

Dividing both sides by -1:

x = 8

So, there are 8 11-year-old students and 30 - 8 = 22 12-year-old students in Liam's class.

The triangle with the greater perimeter has angles 55, 15, and 112 degrees.

In a triangle, the sum of the interior angles is 180 degrees. Thus, if we have two non-congruent triangles with one angle equal (in this case, B = 55 degrees), we can set up an equation to solve for the third angle of the triangle with the greater perimeter.

Let's call the third angle in the first triangle x. Then, x + 55 + b = 180 degrees, or x + b = 125 degrees.

Since we know that a + b + B = 180 degrees for any triangle, we can set up a similar equation for the second triangle: y + 55 + a = 180 degrees, or y + a = 125 degrees.

Since the perimeter of a triangle is equal to the sum of its side lengths, and we know that a = 15 and b = 13, we can set up another equation to find the triangle with the greater perimeter:

Perimeter 1 = 15 + 13 + x and Perimeter 2 = 15 + 13 + y.

Solving for x, we find that x = 125 - b = 125 - 13 = 112 degrees. Solving for y, we find that y = 125 - a = 125 - 15 = 110 degrees.

Since 112 > 110, the triangle with the greater perimeter has angles 55, 15, and 112 degrees.

The triangle with the greater perimeter is the one with the greater value of c, which we can calculate using the law of cosines and the law of sines.

Given two noncongruent triangles with angle B equal to 55 degrees and sides a and b, we need to find the measures of the angles of the triangle with the greater perimeter.

First, let's use the law of cosines to find the measure of angle A in each triangle:

[tex]c^2 = a^2 + b^2 - 2ab * cos(A)\\\\c = \sqrt{(a^2 + b^2 - 2ab * cos(A))} \\\\cos(A) = (a^2 + b^2 - c^2) / 2ab[/tex]

For the first triangle, we can use the given values:

[tex]cos(A) = (15^2 + 13^2 - c^2) / 2 * 15 * 13\\\\c = \sqrt{(15^2 + 13^2 - 2 * 15 * 13 * cos(A))}[/tex]

For the second triangle, we can use a and b as the lengths of the sides opposite angles A and C, respectively. Then we can use the law of sines to find the lengths of the other sides:

[tex]sin(A) / a = sin(C) / c\\\\c = a * sin(C) / sin(A)[/tex]

Substituting values and solving, we get:

[tex]c = 15 * sin(C) / sin(A)\\\\cos(A) = (15^2 + b^2 - c^2) / 2 * 15 * b\\\\c = \sqrt{(15^2 + b^2 - 2 * 15 * b * cos(A))}[/tex]

Now we can compare the two perimeters (the sum of the lengths of all sides) to determine which triangle has the greater perimeter. The perimeter of each triangle will be a + b + c.

Whichever triangle has the larger value of c will have the greater perimeter, as a and b are the same in both triangles.

So, we can use the value of c that we just calculated for each triangle to determine which triangle has the greater perimeter, and therefore, which triangle has the greater measure of its angles.
