approximately 42.5 milligrams of the substance will remain after 22 hours.Since the radioactive substance decays exponentially, we can use the formula:N = N0 * e^(-kt)

where N is the amount of substance remaining after time t, N0 is the initial amount of substance, k is the decay constant, and e is the base of the natural logarithm.

We know that the initial amount of substance is 170 milligrams, and after 12 hours, 85 milligrams remain. We can use these values to solve for the decay constant k:

85 = 170 * e^(-k*12)

Dividing both sides by 170, we get:

0.5 = e^(-k*12)

Taking the natural logarithm of both sides, we get:

ln(0.5) = -k*12

Solving for k, we get:

k = ln(2)/12

Now we can use this value of k to find the amount of substance remaining after 22 hours:

N = 170 * e^(-k*22)

N = 170 * e^(-22*ln(2)/12)

N = 170 * e^(-11*ln(2)/6)

N ≈ 42.5

Therefore, approximately 42.5 milligrams of the substance will remain after 22 hours.

a. The trigonometric identity sin2x/[1 - cos2x] = cotx

b. The trigonometric identity 1 + sin2x = (sinx + cosx)²

Trigonometric identities are mathematical equations that contain trigonometic ratios

a. To verify the trigonometric identity

sin2x/[1 - cos2x] = cotx, we proceed as follows.

To verify the identity, we need to show that Left hand side (L.H.S) equal Right Hand side (R.H.S). So, we proceed as follows

L.H.S = sin2x/[1 - cos2x]

Using the trigonometric identities sin2x = 2sinxcosx and cos2x = cos²x - sin²x, we have that

sin2x/[1 - cos2x] = 2sinxcosx/[1 - cos²x + sin²x]

=  2sinxcosx/[1 - cos²x + sin²x]

= 2sinxcosx/[sin²x + sin²x]     (since  sin²x = 1 -  cos²x)

= 2sinxcosx/2sin²x

= cosx/sinx

= cotx

= R.H.S

Since L.H.S = R.H.S, So,

sin2x/[1 - cos2x] = cotx

b. To verify the trigonometric identity

1 + sin2x = (sinx + cosx)², we proceed as follows.

To verify the identity, we need to show that Left hand side (L.H.S) equal Right Hand side (R.H.S). So, we proceed as follows

L.H.S = 1 + sin2x

Using the trigonometric identities sin2x = 2sinxcosx and sin²x + cos²x = 1, we have that

1 + sin2x = sin²x + cos²x + 2sinxcosx

=   sin²x + 2sinxcosx + cos²x

= [sinx + cosx]²     (since  sin²x + 2sinxcosx + cos²x = [sinx + cosx]²)

= R.H.S

Since L.H.S = R.H.S, So,

1 + sin2x = (sinx + cosx)²

Eris is a dwarf planet in our solar system that's slightly larger than Pluto. It has a highly elongated orbit that takes about 560 Earth years to complete, and it's known to have a small moon named Dysnomia.

First of all, for those who may not be familiar, Eris is a dwarf planet in our solar system that was discovered in 2005.

It's located in the Kuiper Belt, a region of the solar system beyond Neptune that's home to many other small icy objects.
As you mentioned, Eris is slightly larger than Pluto - in fact, it's currently considered to be the largest known dwarf planet in the solar system.

Its diameter is about 2,326 kilometers, compared to Pluto's diameter of 2,377 kilometers.

One interesting thing about Eris is that its orbit around the Sun is highly elongated.

At its closest point to the Sun (known as perihelion), it's about 5.7 billion kilometers away, while at its farthest point (aphelion), it's more than twice as far away - about 14.6 billion kilometers.

This means that Eris has a very long orbital period - the time it takes to complete one full orbit around the Sun.

In fact, as you mentioned, it takes Eris about 560 Earth years to complete one orbit.

To put that in perspective, Pluto - which also has an elongated orbit - takes about 248 Earth years to complete one orbit. S

o Eris's orbital period is more than twice as long as Pluto's!

Another interesting fact about Eris is that it's known to have a small moon, which is officially named Dysnomia.

Dysnomia is much smaller than Eris - its diameter is only about 350 kilometers - but it orbits Eris at a distance of about 37,000 kilometers.

So in summary, Eris is a dwarf planet in our solar system that's slightly larger than Pluto. It has a highly elongated orbit that takes about 560 Earth years to complete, and it's known to have a small moon named Dysnomia.

integral ∫₀¹₂₀ r(t) dt represents the total amount of oil that leaks from the tank in 120 minutes.

To see why, consider the definition of an integral. If we divide the interval [0, 120] into small subintervals of width Δt, then the amount of oil that leaks out during each subinterval is approximately r(t)Δt. Summing up all these small amounts over the entire interval gives:

Σᵢ r(tᵢ) Δt

where tᵢ is the midpoint of the i-th subinterval. As we take the limit as the subinterval width goes to zero, this sum becomes the integral:

Nia's score will be the same as the median score from Ms. Abidor's test, which is 83.5.

To find Nia's score, we first need to determine the median score of the class. The median is the middle value in a set of numbers arranged in order from lowest to highest.

The given grades on the algebra test, arranged in order from lowest to highest, are:

50, 60, 72, 74, 76, 80, 87, 90, 92, 92, 95, 95

There are 12 grades in total, so the median would be the average of the 6th and 7th grades, which are 80 and 87:

Median = (80 + 87) / 2 = 83.5

Since Nia's score did not change the median score, it must be equal to the median score or some other value that does not affect the median when added to the list.

Therefore, Nia's score is either 83.5, if she scored the median score, or any other value such that the median of the list remains the same.

The 98% confidence interval for the population standard deviation σ:

(12.68, 26.66).

To construct a 98% confidence interval for the population standard deviation σ, we can use the chi-square distribution.

The formula for the confidence interval is:

((n-1)s^2)/χ^2(α/2, n-1) ≤ σ^2 ≤ ((n-1)s^2)/χ^2(1-α/2, n-1)

where s is the sample standard deviation, n is the sample size, and χ^2(α/2, n-1) and χ^2(1-α/2, n-1) are the chi-square values for the given level of significance and degrees of freedom.

With n = 19 and s = 9.4, we have:

χ^2(0.01/2, 18) = 36.191 and χ^2(1-0.01/2, 18) = 7.962

Substituting these values into the formula, we get:

((19-1)(9.4)^2)/36.191 ≤ σ^2 ≤ ((19-1)(9.4)^2)/7.962

Simplifying:

160.866 ≤ σ^2 ≤ 711.901

Taking the square root of both sides, we get:

The surface area of the complex shape is 3,737,996 square feet.

To find the surface area of this complex shape, we need to break it down into simpler shapes and calculate their individual surface areas.

First, we can see that the shape consists of a rectangular prism (the block) and two triangular prisms (the roofs).

The rectangular prism has dimensions of 408 ft x 458 ft x 545 ft, and the triangular prisms have a height of 720 ft and a base of 680 ft.

The surface area of the rectangular prism is given by:

2lw + 2lh + 2wh = 2(408 x 458) + 2(408 x 545) + 2(458 x 545)

                          = [tex]1,739,276 ft^2[/tex]

The surface area of one of the triangular prisms is given by:

2(lw/2) + lh + wb = 2(680 x 720/2) + 720 x 408 + 680 x 545

                           = [tex]999,360 ft^2[/tex]

Since there are two triangular prisms, we need to multiply this by 2:

2(999,360) = 1,998,720 [tex]ft^2[/tex]

Therefore, the total surface area of the complex shape is:

1,739,276 + 1,998,720 = 3,737,996 [tex]ft^2[/tex]

So, the surface area of the complex shape is 3,737,996 square feet.

The measure of angle IHJ is 180 - (90 + 36) = 54 degrees.

To find the measure of angle IHJ, we need to use the formula for the area of a sector of a circle:

Area of sector = (θ/360) x πr^2,

where θ is the central angle of the sector in degrees and r is the radius of the circle.

In this problem, we know that the area of the shaded sector is 40π, and we can find the radius of circle H by using the formula for the area of a circle:

Area of circle = πr^2,

which gives us:

πr^2 = 100 (since hi = 10, r = hi)

r = 10/π (dividing both sides by π)

Now we can use the formula for the area of a sector to find the measure of angle IHJ:

40π = (θ/360) x π(10/π)^2

40π = (θ/360) x 100

θ/9 = 4

θ = 36

Here, w is a function of x and y, and we use the partial derivative notation to indicate that we are finding the rate of change of w with respect to each of its independent variables, holding the other variable constant.

The dx/dr and dy/dr terms represent the rates of change of x and y with respect to r, respectively.

The logarithm as a sum or difference of logarithms is log(8/27) = log(8) - log(27) = log([tex]2^3[/tex]) - log([tex]3^3[/tex]) = 3log(2) - 3log(3)

To write a logarithm as a sum or difference of logarithms, we need to use the following properties of logarithms:

log(ab) = log(a) + log(b) 2. log(a/b) = log(a) - log(b) 3. log([tex]a^b[/tex]) = b log(a)

Let's work through an example to see how this works.

Suppose we have the logarithm log(3[tex]x^2[/tex] / 4y).

To write this as a sum or difference of logarithms, we need to use property 2 above: log(3[tex]x^2[/tex] / 4y) = log(3[tex]x^2[/tex]) - log(4y)

Now we need to simplify each term as much as possible using properties 1 and 3.

For the first term, we can use property 3 to move the exponent outside the logarithm: log(3[tex]x^2[/tex]) = 2 log(x) + log(3)

For the second term, we can use property 1 to write:

log(4y) = log(4) + log(y)

Putting it all together, we get: log(3x^2 / 4y) = 2 log(x) + log(3) - log(4) - log(y)

This is the sum or difference of logarithms that represents the original logarithm, and it's been simplified as much as possible using the logarithm properties.

The number which best completes the sequence is 13, but since it's not in the given options, there might be an error in the question or the answer choices.

The pattern in this sequence is not immediately obvious, but we can try to identify some relationships between the numbers.

Starting with the first two numbers, we can see that the second number is obtained by multiplying the first number by 3 and adding 3:

2 x 3 + 3 = 9

Next, we can see that the third number is obtained by subtracting 4 from the second number:

9 - 4 = 5

The fourth number is obtained by adding 8 to the third number:

5 + 8 = 13

The fifth number is obtained by subtracting 3 from the fourth number:

13 - 3 = 10

The sixth number is obtained by adding 9 to the fifth number:

10 + 9 = 19

At this point, we can see that the pattern seems to be alternating between adding and subtracting some value. We can try to extend this pattern to find the missing number:

Starting with the sixth number, we subtract 2:

19 - 2 = 17

Next, we can add some value to get the next number. Based on the pattern we've seen so far, it seems likely that this value is 11:

17 + 11 = 28

However, 28 is not one of the options given. We can try to use the pattern to find another option. If we subtract 1 from the sixth number instead of 2, we get:

19 - 1 = 18

And if we add 8 instead of 11, we get:

18 + 8 = 26

26 is not one of the options given either, but it seems like a reasonable choice based on the pattern we've identified. Therefore, the number which best completes the sequence below is:

c) 25

To find the number that best completes the sequence, let's first identify the pattern. The sequence is as follows:

2 9 5 13 10 19 17 ?

Looking closely, we can see that there are two alternating patterns:

Pattern 1: Add 7 (2 to 9, 5 to 13, 10 to 17)
Pattern 2: Subtract 4 (9 to 5, 13 to 10, 19 to ?)

Now let's apply the pattern to find the next number in the sequence:

17 (the last number) - 4 (following Pattern 2) = 13

So, the number which best completes the sequence is 13, but since it's not in the given options, there might be an error in the question or the answer choices.

The measure of angle NLM is 38°.

Firstly, let's visualize the triangle LMN. We know that LN is extended through point N to point O. This means that we have a line segment that starts at point L, passes through point N, and continues on to point O. This creates an angle at point N which we will call angle MON.

Next, we are given the measure of angle MNO. We can write this as:

m∠MNO = (52 – 13)° = 39°

We can also write the measure of angle LMN as:

m∠LMN = (2x+19)°

To find the value of x, we can use the fact that the sum of the angles in a triangle is always 180°. Therefore, we can write an equation using the measures of the angles in triangle LMN:

m∠LMN + m∠NLM + m∠MNO = 180°

Substituting the values we know, we get:

(2x+19)° + (x-4)° + 39° = 180°

Simplifying this equation, we get:

3x + 54 = 180

Subtracting 54 from both sides, we get:

3x = 126

Dividing both sides by 3, we get:

x = 42

Now that we know the value of x, we can find the measure of angle NLM:

m∠NLM = (x-4)° = (42-4)° = 38°

The unity gain frequency of this amplifier is 6 MHz.

To find the unity gain frequency, we need to use the Gain-Bandwidth Product (GBP) formula, which states that GBP = Gain × Bandwidth. In this case, we have an amplifier with a gain of 40 and a bandwidth of 150 kHz.

1. Convert the bandwidth to Hz: 150 kHz = 150,000 Hz
2. Multiply the gain by the bandwidth: 40 × 150,000 Hz = 6,000,000 Hz
3. Convert the result to MHz: 6,000,000 Hz = 6 MHz

Conclusion: Based on the GBP formula, the unity gain frequency of this amplifier is 6 MHz.

The maximum amount of profit the company can make is $1,209.

To find the maximum amount of profit the company can make, we need to find the vertex of the quadratic function given by the equation:

y = -[tex]x^2[/tex] + 78x - 543

The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

where a is the coefficient of the [tex]x^2[/tex] term, b is the coefficient of the x term, and c is the constant term.

In this case, a = -1, b = 78, and c = -543, so:

x = -78 / (2*(-1)) = 39

The y-coordinate of the vertex can be found by substituting x = 39 into the equation:

y = -[tex]39^2[/tex] + 78(39) - 543

  = 1209

Therefore, the maximum amount of profit the company can make is $1,209.

Note: that since profit is given in dollars, we round our answer to the nearest dollar.
