Formula for comparative advantage is

CA=rate of producing large tubes/rate of producing small tube

For 1 Sparkling:

CA = 100/200

CA = 0.5

For 2 Bright White:

CA = 100/250

CA = 0.5

For 3 Fresh:

CA = 200/250

CA = 0.8

For 4 Mint:

CA = 150/150

\(\sf \bf m^6\)

Step-by-step explanation:

 In exponent multiplication, if bases are same, add the powers.

      \(\sf \boxed{\bf a^m*a^n =a^{m+n}}\)

\(\sf m^9 * m^{-3}=m^{9 +(-3)}\)

               \(\sf = m^{6}\)

The coordinates of the point P at which the tangent line passes through (5,0) graph of f(x) = 9 - x² is (-16, 9)

The coordinates of the point on the graph is the values at which the curve cuts the x-axis at these points (5,0)

The given graph f(x) = 9-x²

By substitution we have

f(x) = 9-(5)²

⇒f)x) = 9-25

f(x) = -16

Also, from the same function

We have f(x) 9-x²

⇒f(x) = 9-(0)²

f(x) 9-0 = 9

Therefore the coordinates of the graph at the point p is (-16, 9)

The measure of 2 is 120 degrees.

The measure of an angle is typically given in degrees, which is a unit of measurement for angles.

In this case, we are looking for the measure of angle 2, which is one of the angles in a triangle.

To find the measure of angle 2, we need to use the fact that the angles in a triangle add up to 180 degrees.

Since we know that angle 1 is 30 degrees and angle 3 is 30 degrees, we can subtract those two angles from 180 to get the measure of angle 2.

Therefore, 180 - 30 - 30 = 120 degrees.

Summary: The measure of angle 2 is 120 degrees, which was found by subtracting the measures of angles 1 and 3 from 180 degrees since the angles in a triangle add up to 180 degrees.

A has 156 cards, B has 39 cards, and J has 312 cards.

To find out how many cards A, B, and J have, follow these steps:

Let the number of cards B has be represented by the variable 'b'.

A has four times as many cards as B, so the number of cards A has can be represented as '4b'.

J has twice as many cards as A, so the number of cards J has can be represented as '2(4b)' or '8b'.

Together, A and J have 468 cards. Therefore, the equation can be written as 4b + 8b = 468.

Combine the like terms: 12b = 468.

Divide both sides of the equation by 12 to find the value of 'b': b = 468 / 12, which results in b = 39.

Now that we have the value of 'b', we can find the number of cards A and J have:

- A has 4 times as many cards as B: A = 4 × 39 = 156 cards.

- J has twice as many cards as A: J = 2 × 156 = 312 cards.

So, A has 156 cards, B has 39 cards, and J has 312 cards.

Answer:

Jada should have multiplied both sides of the equation by 108.

Step-by-step explanation:

The question is incomplete. Find the complete question in the comment section.

Given the equation -4/9 = x/108, in order to determine Jada's error, we need to solve in our own way as shown:

Step 1: Multiply both sides of the equation by -9/4 as shown:

-4/9 × -9/4 = x/108 × -9/4

-36/-36 = -9x/432

1 = -9x/432

1 = -x/48

Cross multiplying

48 = -x

x = -48

It can also be solved like this:

Given -4/9 = x/108

Multiply both sides by 108 to have:

-4/9 * 108 = x/108 * 108

-4/9 * 108 = 108x/108

-432/9 = x

x = -48

Jada should have simply follow the second calculation by multiplying both sides of the equation by 108 as shown.

Step-by-step explanation: Took the test

The values of the missing angles and sides after dilation are:

m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

Thus, by way of scale factor we can say that:

BC/B'C' = BD/B'D' = 36/18 = 2

B'D' = ¹/₂BD = ¹/₂ * 22 = 11

ΔC'P'Q ∼ ΔCPQ

Thus:

C'Q'/CQ = C'D'/CD = D'Q'/DQ

CQ = 2C'Q' = 2 * 3 = 6

Therefore, m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

Answer:

120 mm²

800 in.²

Step-by-step explanation:

Upper figure:

Large rectangle in the middle:

    length = 5 mm + 6 mm + 5 mm = 16 mm

    width = 6 mm

    area = 16 mm × 6 mm = 96 mm²

2 congruent triangles:

    base = 6 mm

    height = 4 mm

    area of each triangle = 6 mm × 4 mm / 2 = 12 mm²

Total area of net = 96 mm² + 2 × 12 mm² = 120 mm²

Lower figure:

Square in the middle:

    side = 16 in.

    area = 16 in. × 16 in. = 256 in.²

4 congruent triangles:

    base = 16 in.

    height = 17 in.

    area of each triangle = 16 in. × 17 in. / 2 = 136 in.²

Total area of net = 256 in.² + 4 × 136 in.² = 800 in.²

The Nyquist rate problem involves finding the highest numerical frequency and the Nyquist rate for a given signal.

A. (a) The highest numerical frequency M present in the signal f(t) = sin(t) is 1.

(b) The Nyquist rate N for sampling this signal is 2.

(c) To avoid aliasing, we can choose any sampling period T that satisfies the condition T < 1/M, which in this case would be T < 1/1 or simply T < 1.

(d) No, we do not recover the signal f. The signal f(t) = sin(t) does not have any frequency components above 1, but the sampled signal g, when passed through a low-pass filter with threshold Mo = 4, will retain frequency components up to 2 due to the Nyquist rate. This will introduce additional frequency components that were not present in the original signal, causing a deviation from the original signal f(t).

Explanation:

(a) The signal f(t) = sin(t) has a single frequency component, which is 1. The numerical frequency represents the number of cycles of the signal that occur per unit time.

(b) The Nyquist rate N is defined as twice the highest numerical frequency in the signal. In this case, the highest numerical frequency M is 1, so the Nyquist rate N would be 2.

(c) To avoid aliasing, the sampling period T should be chosen such that it is smaller than the reciprocal of the highest numerical frequency. In this case, the highest numerical frequency is 1, so we need T < 1/1 or simply T < 1. Any sampling period smaller than 1 will avoid aliasing.

(d) When the signal f is sampled with a period T, the resulting sampled signal g will have frequency components up to the Nyquist rate N. In this case, N is 2, so the sampled signal g will contain frequency components up to 2. When we pass g through a low-pass filter with threshold Mo = 4, it will remove any frequency components above 4. Since the original signal f does not have any frequency components above 1, the filtered signal will have additional frequency components (between 1 and 2) that were not present in the original signal. Therefore, we do not recover the signal f exactly.

The new co- ordinates are:

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size.

To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.

Given Co- ordinates:

X(2, -1), Y(-4, -1), and Z(2, 2).

Now, the scale factor is 4.

So, we have to multiply each coordinate point by 4.

X(2, -1) -> (8, -4)
