The required sign between -12.7a and -12.7b should be greater than sign (>).

If a is less than b, then -12.7a will be greater than -12.7b, because multiplying a smaller number by a negative constant (-12.7 in this case) will result in a larger negative value than multiplying a larger number by the same constant.

To see this, suppose we have two positive numbers x and y such that x < y. Then, multiplying both by a negative constant c will result in two negative numbers with magnitudes that are greater for x:

cx < cy, because c is negative and (x < y)

Therefore, if a is less than b, then:

-12.7a > -12.7b

So the sign between -12.7a and -12.7b should be greater than sign (>).

Find the exact value of the closed loop gain when the amplifier works with its minimum gain.

The closed loop gain of an amplifier is given by the formula:

G = (A/(1+Aβ))

where A is the open loop voltage gain and β is the feedback factor

We are given that the open loop voltage gain varies from 100000 to 200000.

Hence, its minimum value is 100000.

We are also given that the closed loop gain G is 500.

We can use this information to find the feedback factor β as follows:

500 = (100000/(1+100000β))β = 999/100000

Substituting the value of β in the formula for G, we get:

G = (100000/(1+100000(999/100000)))

G = 1/947.5

Hence, the exact value of the closed loop gain when the amplifier works with its minimum gain is G = 1/947.5.

Hence, the correct option is (a) G = 1/947.5.

a. The function g(t) = -2t^2 + 3t + 5 is decreasing on the open interval (-∞, 3/4) and increasing on the open interval (3/4, +∞).

To determine the intervals on which the function g(t) = -2t^2 + 3t + 5 is increasing or decreasing, we need to analyze its derivative. Taking the derivative of g(t) with respect to t, we get g'(t) = -4t + 3.

To find where g'(t) = 0, we set -4t + 3 = 0 and solve for t. Solving this equation, we find t = 3/4.

Now, let's examine the sign of g'(t) in the intervals around t = 3/4.

For t < 3/4, if we choose a value less than 3/4, g'(t) will be positive since -4t is a decreasing function. This indicates that g(t) is increasing in the interval (-∞, 3/4).

For t > 3/4, if we choose a value greater than 3/4, g'(t) will be negative since -4t is a decreasing function. This indicates that g(t) is decreasing in the interval (3/4, +∞).

Therefore, the function g(t) is decreasing on the open interval (-∞, 3/4) and increasing on the open interval (3/4, +∞).

What is Total Length?

Whole Length (TL) is the measurement taken in a straight line, with the fish lying on its side, from the tip of the snout to the end of the tail (caudal fin).

The total length of the road trip is 13.2 hours.

Highway signs are posted every 0.06 hours. To find out how many highway signs are on the road trip, we can divide the total length of the road trip by the interval between each sign and then add one more sign for the end of the road trip:

(number of signs) = (total length of road trip) / (interval between signs) + 1

Substituting the values, we get:

(number of signs) = 13.2 / 0.06 + 1

(number of signs) = 220 + 1

(number of signs) = 221

Answer:

A) \(\frac{3}{5}\)

Step-by-step explanation:

The graph goes up 3, to the right 5 between the two points, making the slope \(\frac{3}{5}\).

Points $a$, $b$, $c$, and $d$ are the midpoints of the sides of the larger square. If the larger square has an area of 60, the smaller square's area is 15 square units.

A square's midpoints connect, making it possible to divide the square into four equal squares. Each of these four squares has a side length of half that of the larger square.

Consider the fact that the area of the larger square is 60, with sides of $s$ units. \($s^2=60$\\\). Now, the smaller square is created by connecting the midpoints of the larger square. Each side of the smaller square has a length of \($s/2$\) units.

Since the area of a square is \($s^2$\), the area of the smaller square is \($\left(\frac{s}{2}\right)^2$\). Simplifying gives \($\left(\frac{s}{2}\right)^2=\frac{s^2}{4}$\). So, the area of the smaller square is \($\frac{1}{4}$\) of the larger square's area.

We know that the area of the larger square is 60. Therefore, the area of the smaller square is \($\frac{1}{4}$\) (60) = 15 square units.

First we need to know how many customers in total received a coupon the day that there were 150 customers.

If for each 25 customers, 3 received a coupon. 0.12 of customers received a coupon (\(\frac{3}{25}\) = 0.12)

You can multiply this value by 150 to get 0.12 x 150 = 18 people

Another way you can think about this is 150/25 = 6 and 6 x 3 = 18 people

Now that we know how many people received coupons, we need to find the monetary value of these coupons. To do this, we multiply 18 by $10. Therefore, the total value of the coupons that were given out was $180.

The device that indicates whether two AC sources to be connected in parallel are in the correct phase relationship is called a synchronizing device.

A synchronizing device is a mechanism that ensures that two AC sources are in sync when they are connected in parallel. It's used to match the voltage, frequency, and phase angle of two alternating current (AC) sources.

It guarantees that the power supplied by both generators is synchronized, allowing them to be combined into a single electrical system without disrupting the balance of the current or causing a short circuit.

As a result, it is critical to the safe and efficient operation of power systems. A phase sequence indicator (PSI) or a synchroscope is often used as a synchronizing device. It works by providing an indication of the voltage difference, the phase angle difference, and the frequency difference between two AC sources that are to be synchronized.

Therefore, a synchronizing device is an instrument that determines whether two alternating current (AC) sources to be connected in parallel are in the appropriate phase relationship.

(a) The elementary matrix is row reduction.

(b) The matrix is reduced by using the row operation

(c) if A is an invertible matrix, we can perform a sequence of elementary row operations to reduce it to an identity matrix I.

(d) The product of elementary matrices is (2 4) (2 5)

(a) To find the inverse of matrix A, we perform row reduction to transform it into an identity matrix, while also performing the same operations on the identity matrix to obtain the inverse. The elementary matrices corresponding to each step in the row reduction process are as follows:

E1 = interchange rows 1 and 2

E2 = multiply row 2 by -1/3

E3 = add 5 times row 2 to row 1

E4 = subtract 4 times row 2 from row 1

(b) Each elementary matrix corresponds to a specific row operation, which can be interpreted geometrically as follows:

E1: Interchanging rows 1 and 2 is equivalent to reflecting the matrix across the line y=x. This changes the orientation of the coordinate system.

E2: Multiplying row 2 by -1/3 scales the matrix vertically by a factor of 1/3. This compresses the matrix in the y-direction.

E3: Adding 5 times row 2 to row 1 translates the matrix vertically by 5 units. This shifts the entire matrix upwards.

E4: Subtracting 4 times row 2 from row 1 translates the matrix horizontally by 4 units. This shifts the entire matrix to the left.

(c)  To prove this, we use the fact that every elementary matrix is invertible. This sequence of row operations corresponds to a product of elementary matrices E1, E2, ..., En.

(d)  By computing the inverses of each elementary matrix and multiplying them in the correct order, we obtain the following product:

A = (1 0) ( 0 1) ( -5 4) ( 1 0 ) ( -1/3 0 ) ( 0 1 ) ( 1 0 ) ( 0 5 ) ( 1 0 ) ( 0 -4 ) ( 1 0 )

We can verify that this product indeed gives the matrix A by multiplying the matrices in the given order:

A = (1 0) ( 0 1) ( -5 4) ( 1 0 ) ( -1/3 0 ) ( 0 1 ) ( 1 0 ) ( 0 5 ) ( 1 0 ) ( 0 -4 ) ( 1 0 )

= (2 4) (2 5)

Therefore, we have expressed matrix A as a product of elementary matrices.

Alice is 55 km from her starting point after walking a distance of 55 km along the perimeter of the park.

To find the distance Alice is from her starting point after walking along the perimeter of the park, we can use the concept of congruent sides in a regular hexagon.

The perimeter of a regular hexagon is equal to the sum of its six congruent sides. Given that each side of the hexagon is 22 km long, the total perimeter of the hexagon is 6 * 22 km = 132 km.

Since Alice walks a distance of 55 km along the perimeter of the park, we can determine the number of complete laps she makes around the hexagon by dividing the distance she walked by the perimeter of the hexagon: 55 km / 132 km = 0.4167 laps.

As Alice starts and ends at a corner of the hexagon, each complete lap brings her back to the same corner. Therefore, the fractional part of the number of laps represents the portion of the hexagon's perimeter she has traveled beyond the starting corner.

To find the remaining distance from Alice's current position to the starting point, we calculate the fractional part of the number of laps and multiply it by the perimeter of the hexagon: 0.4167 * 132 km = 55 km.

A regular hexagon is a polygon with six congruent sides. In this problem, the regular hexagon represents the shape of the park, and each side of the hexagon has a length of 22 km. The perimeter of the hexagon is found by multiplying the length of one side by the number of sides, which is 6. Therefore, the perimeter of the hexagon is 6 * 22 km = 132 km.

When Alice walks along the perimeter of the park for a distance of 55 km, we need to determine how many complete laps she makes around the hexagon. By dividing the distance she walked by the perimeter of the hexagon, we find that she completes approximately 0.4167 laps.

Since Alice starts and ends at a corner of the hexagon, each complete lap brings her back to the same corner. Therefore, the fractional part of the number of laps represents the portion of the hexagon's perimeter she has traveled beyond the starting corner.

In this case, multiplying 0.4167 by 132 km gives us a result of approximately 55 km. Therefore, Alice is 55 km from her starting point after walking a distance of 55 km along the perimeter of the park.
