The measures in the circle given in the image above are calculated as:

1. m<PSQ = 130°;   2. m<AQS = 30°; 3. m(QR) = 100°; 4. m(PS) = 110°; 5. (RS) = 70°.

In order to find the measures in the circle shown, recall that according to the inscribed angle theorem, the measure of intercepted arc is equal to the central angle, but is twice the measure of the inscribed angle.

1. m<PSQ = m<PAQ

Substitute:

m<PSQ = 130°

2. Find m<PBQ:

m<PBQ = 1/2(m(PQ) + m(RS)) [based on the angles of intersecting chords theorem]

Substitute:

m<PBQ = 1/2(130 + 2(35))

m<PBQ = 100°

m<AQS = 180 - [m<BAQ + m<PBQ]

Substitute:

m<AQS = 180 - [(180 - 130) + 100]

m<AQS = 30°

3. m(QR) = m<QAR

Substitute:

m(QR) = 100°

4. m(PS) = 180 - m(RS)

Substitute:

m(PS) = 180 - 2(35)

m(PS) = 110°

5. m(RS) = 2(35)

m(RS) = 70°

After finding the speed of both objects, we found that 264km travelled in 2 hours is the fastest of both.

What is meant by the speed of an object?

A thing's speed is the rate at which it covers a distance in a given amount of time. The object that moves quickly covers a greater distance in less time. On the other hand, items that move slowly cover a relatively small distance in a given period of time. As speed simply has no direction and only magnitude, it is a scalar quantity. The instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the object divided by the duration of the period.

We are asked to find the speed of two different objects.

Object 1

Distance travelled = 264km

Time taken = 2 hours

Speed = distance/time = 264/2 = 132km/h

Object 2

Distance travelled = 585km

Time taken = 5 hours

Speed = distance/time = 585/5 = 117 km/h

From the above two speeds, we can see that object 1 travels 132km in one hour while object 2 only travels 117km in one hour.

Therefore after finding the speed of both objects, we found that 264km travelled in 2 hours is the fastest of both.

First, let's simplify the expression within the parentheses

[cos (41°) + i sin (41°)] × [14 cos (128°) + i sin (128°)]

Using the product-to-sum identities for trigonometric functions

cos (a) cos (b) - sin (a) sin (b) = cos (a + b)

sin (a) cos (b) + cos (a) sin (b) = sin (a + b)

Applying these identities, we have

[cos (41°) + i sin (41°)] × [14 cos (128°) + i sin (128°)]

= [cos (41°) cos (128°) - sin (41°) sin (128°)] + i [sin (41°) cos (128°) + cos (41°) sin (128°)]

= (7 cos (41) + 7i sin (41)) × (14 cos (128) + i sin (128))

= 98 cos (41) cos (128) - 98 sin (41) sin (128) + 98i sin (41) cos (128) + 98i cos (41) sin (128).

Answer:

Start with equation,

         y''(x) = f(x) = 6y/(10x-x²)               about point x₀ = 5

Then,

       y(x) = a₀ + a₁(x-5) + a₂(x-5)²+ a₃(x-5)³ + a₄(x-5)⁴...….

by inspection,

           y(5) = a₀      and       y'(5) = a₁

then,

y''(5) = 6a₀/(50-25) = 6a₀/25              

y'''(x) = 6y'/(10x-x2) - 6y(10-2x)/(10x-x2)2

then,                      

                              y'''(5) = 6a₁/25 - 0 = 6a₁/25                

y''''(x) = 6y''/(10x-x2) -12y'(10-2x)/(10x-x2)² + 12y/(10x-x2)² + 12y(10-2x)2/(10x-x2)³

then,

    y''''(5) = (6/25)(6a₀/25) + 0 + 12a₀/625 + 0

The probability that 2 red balls and 2 blue balls are taken from the box is 3/7. This can be expressed mathematically as \((8C2 * 8C2) / (16C4) = 3/7\).

To better understand this probability, let's look at an example. Say there are 8 red balls and 8 blue balls in the box. This can be represented as:

R = 8, B = 8

We want to determine the probability of taking 2 red balls and 2 blue balls out of the box. To do this, we need to calculate the total number of ways of selecting 4 balls from the box (16 balls in total) and then calculate the total number of ways of selecting 2 red and 2 blue balls out of the box.

The total number of ways of selecting 4 balls from the box can be expressed as (16C4). This is calculated by dividing the number of ways of selecting 4 balls out of 16 (16!) by the number of ways of arranging those 4 balls in any order (4!):

\((16C4) = 16! / 4! = 1820\)

The total number of ways of selecting 2 red and 2 blue balls out of the box can be expressed as (8C2 * 8C2). This is calculated by multiplying the number of ways of selecting 2 red balls out of 8 (8C2) by the number of ways of selecting 2 blue balls out of 8 (8C2):

\((8C2 * 8C2) = 8C2 * 8C2 = 28\)

The probability of taking 2 red balls and 2 blue balls out of the box is then the ratio of the number of ways of selecting 2 red and 2 blue balls out of the box (28) to the total number of ways of selecting 4 balls from the box (1820):

P(2 red balls, 2 blue balls) = 28 / 1820 = 3/7

In conclusion, the probability of taking 2 red balls and 2 blue balls out of a box containing 8 red balls and 8 blue balls is 3/7.

It will take Jamie 31 months to recoup her investment in the solar panels.

To calculate the time it takes to recoup the investment, we can use the formula for the number of periods needed to reach a future value with compound interest. In this case, the future value is the cost of the solar panels ($33,588.0), and the interest rate is 12% per year, compounded monthly.

We need to find the number of months it takes to reach a future value of $33,588.0 with monthly contributions of $1,200 and a monthly interest rate of 1% (12% divided by 12).

Using the formula for the number of periods (n) needed to reach a future value (FV) with monthly contributions (PMT) and monthly interest rate (r), we have:

FV = PMT * [(1 + r)ⁿ - 1] / r

$33,588.0 = $1,200 * [(1 + 0.01)ⁿ - 1] / 0.01

Solving for n, we find n ≈ 31 months. Therefore, it will take Jamie 31 months to recoup her investment in the solar panels.

There are 1470 commuters take both the bus and the subway.

To find the number of commuters who take both the bus and the subway, we can use the principle of inclusion-exclusion.

Let's denote:

A = Number of commuters who take the subway

B = Number of commuters who take the bus

N = Total number of commuters

From the given information:

A = 1190 (number of commuters who take the subway)

B = 640 (number of commuters who take the bus)

N = 1700 (total number of commuters)

We also know that 180 commuters do not take either the bus or the subway.

To find the number of commuters who take both the bus and the subway, we can use the formula:

A ∪ B = A + B - A ∩ B

where A ∪ B represents the union of A and B, and A ∩ B represents the intersection of A and B.

Substituting the values we have:

A ∪ B = 1190 + 640 - 180

A ∪ B = 1650

Therefore, 1650 commuters take either the bus or the subway (or both). To find the number of commuters who take both the bus and the subway, we subtract the number of commuters who take neither:

Number of commuters who take both the bus and the subway = A ∪ B - Neither

Number of commuters who take both the bus and the subway = 1650 - 180

Number of commuters who take both the bus and the subway = 1470

Therefore, 1470 commuters take both the bus and the subway.

if B is a symmetric matrix, then the matrix C = \(\rm A^TBA\) is also symmetric. The correct answer is: C. Symmetric.

It means that \(\rm B^T\)= B, where \(\rm B^T\) denotes the transpose of matrix B.

Now let's consider the matrix C = \(\rm A^TBA\).

To determine whether C is symmetric or not, we need to check if C^T = C.

Taking the transpose of C:

\(\rm C^T = (A^TBA)^T\)

\(\rm = A^T (B^T)^T (A^T)^T\)

\(\rm = A^TB^TA\)

Since B is symmetric (\(\rm B^T = B\)), we have:

\(\rm C^T = A^TB^TA\)

\(\rm = A^TB(A^T)^T\)

\(\rm = A^TBA\)

Comparing \(\rm C^T\) and C, we can see that \(\rm C^T\) = C.

As a result, if matrix B is symmetric, then matrix \(\rm C = A^TBA\) is also symmetric. The right response is C. Symmetric.
