The equation describes the line in the slope-intercept form will be y = (1/3)x +(2/3). Option A is correct.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

It is given that the slope of the line is −1/3 and passes through the points (−2,3)

A straight line is a combination of endless points joined on both sides of the point. It is shown by the slope-intercept form.

The standard form of the slope-intercept is,

y-y₁ = m(x-x₁)

y-3=−1/3(x-(-2)

y-3=-1/3(x+2)

y = -1/3 x - 2/3 +3

y= -1/3x -7/3.

Thus, the equation describes the line in the slope-intercept form will be y = (1/3)x +(2/3). Option A is correct.

h = 20.5 yards

Step-by-step explanation:

Volume of Rectangular Pyramid: lwh/3

492 = (18) * (4) (h) /3

Multiply 3 on both sides

1476 = (18) (4) (h)

1476 = 72h

h = 41/2 or 20.5 yards

The total cost to produce 30 bicycles is $11,250.00. The profit on the first 30 bicycles is $1,350.00. The marginal profit on the 31st bicycle is $7.17.

To find the total cost to produce 30 bicycles, we need to calculate the cumulative cost of producing each bicycle up to the 30th bicycle. The marginal cost function C'(q) provides the additional cost of producing one bicycle at a given quantity q.

By integrating C'(q) with respect to q, we can obtain the total cost function C(q).

Given C'(q) = 600/(0.3q) + 5, we can integrate it to find C(q):

C(q) = 600ln(0.3q) + 5q + C1

Since C(q) represents the total cost, we can determine the constant C1 by considering the fixed cost of $2,100 when no bicycles are produced (C(0) = 2,100). By substituting this value into the equation and solving for C1, we find C1 = 1,500.

Therefore, the total cost to produce 30 bicycles (C(30)) is:

C(30) = 600ln(0.3*30) + 5*30 + 1,500 ≈ $11,250.00

To calculate the profit on the first 30 bicycles, we subtract the total cost from the revenue obtained by selling the bicycles. Since each bicycle is sold for $220, the revenue from selling 30 bicycles is 30 * $220 = $6,600. The profit is then:

Profit = Revenue - Total Cost = $6,600 - $11,250.00 ≈ -$4,650.00

The negative profit indicates a loss on the first 30 bicycles.

Finally, to find the marginal profit on the 31st bicycle, we need to calculate the difference between the revenue and the additional cost of producing the 31st bicycle. The marginal profit is given by the difference between the marginal revenue (MR) and the marginal cost (MC) at q = 31.

Since the revenue from selling one bicycle is $220, the marginal revenue is MR = $220. The marginal cost is obtained by evaluating C'(31):

MC(31) = 600/(0.3*31) + 5 ≈ $34.17

Therefore, the marginal profit on the 31st bicycle is:

Marginal Profit = MR - MC = $220 - $34.17 ≈ $185.83 ≈ $185.80

The correct answer is C, the statement is false and It can be changed to "If x is in set M, then x is not in set R."

Based on the options provided, the correct answer is C.

The statement is false. It can be changed to "If x is in set M, then x is not in set R."

To explain why this answer is correct, let's break down the original statement and the suggested change:

Original statement: "if xeM. than xeR."

Suggested change: "If x eM. then × prR"

The original statement is unclear and seems to contain typos or errors.

However, the suggested change provides a clearer and more meaningful statement.

The suggested change can be translated as follows:

"If x is in set M, then x is not in set R."

This means that if an element belongs to set M, it cannot belong to set R at the same time.

It establishes a relationship between the two sets where the presence of an element in one set excludes its presence in the other.

In conclusion, the correct answer is C.

The statement is false.

It can be changed to "If x is in set M, then x is not in set R."

"The eigenvalues of the square of two matrices are not necessarily equal to the square of the eigenvalues of each of the matrices". The statement is incorrect.

Eigenvalues of the square of two matrices (A*B) are not necessarily equal to the square of the eigenvalues of each matrix (A and B).

In general, eigenvalues of the product of two matrices do not follow the same relationship as their individual eigenvalues.

In fact, there is no simple relationship between the eigenvalues of a matrix and the eigenvalues of its square. The eigenvalues of a matrix and its square can be different, and even if they are the same, their relationship is not necessarily as simple as taking the square root.

However, if the two matrices commute, meaning A*B = B*A, their eigenvalues may exhibit some specific relationships, but this is not guaranteed in all cases.

There are 3 rectangles for the lateral surface area

LA=Ph           lateral surface area is the are around which is found Permiter*height

LA=(7.5+10.5+11)9.5=275.5

Total area = LA + 2B                    B is the area of the base 1/2 bh

A=275.5+2(1/2)(10.5)(6)

Step-by-step explanation:

By definition, pi is equal to c/d, where c is the circumference and d is the diameter.

This means that C = pi(d).

However, since diameter is twice the radius, if we let the radius be r cm, d=2r.

This gives that C=2pi(r).

There are four significant figures in the number 1.032.

Significant figures are the digits in a number that carry meaningful information about its precision. To determine the significant figures in a number, follow these rules:

Non-zero digits are always significant. In this case, the digits 1, 0, 3, and 2 are non-zero.

Zeroes between non-zero digits are significant. In this case, the zero between 1 and 3 is significant.

Leading zeroes (zeros before the first non-zero digit) are not significant. In this case, there are no leading zeroes.

Trailing zeroes (zeros after the last non-zero digit) are significant only if there is a decimal point present. In this case, there is a trailing zero after the 2, and since there is a decimal point, it is significant.

By applying these rules, we find that the number 1.032 has four significant figures.

=======================================================

Explanation:

Matia claims that \(x^2 > x\)

However, the claim isn't true when 0 ≤ x ≤ 1.

For example, x = 0 leads to \(x^2 = 0^2 = 0\)

Meaning that \(x^2 > x\) would update to \(0 > 0\) which is false.

------------------

Similarly, if x = 0.5, then

\(x^2 > x\\\\0.5^2 > 0.5\\\\0.25 > 0.5 \ \text{which is also false}\\\\\)

Because the last inequality is false, the first inequality must also be false for x = 0.5

-------------------

Those last two previous sections showed that x = 0 and x = 0.5 are counter-examples to Matia's claim to thereby prove it false.

In this question we need to decrease 216 by \(37\dfrac{1}{2}\%\) or 37.5 %.

For this, firstly find 37.5 % of 216.

\(37.5\%\ \text{of}\ 216=\dfrac{37.5}{100}\times 216\\\\=81\)

Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.

So,

216-81 = 135

Hence, 135 is the decrease of 216 by 37.5 %.

The percentage decrease of 216 by 37 1/2% be is 135

Given:

Original value = 216

Percentage decrease = 37 ½%

Decrease = 37 ½% of 216

= 75/2 ÷ 100 × 216

= 37.5 / 100 × 216

= 0.375 × 216

= 81

New value = Original value - Decrease

= 216 - 81

= 135

Therefore, the percentage decrease of 216 by 37 1/2% be is 135

The amount of carbon-14 remaining after 20 millennia is 0.912 mg.

The exponential decay function for a 24-mg sample of carbon-14 can be represented by the equation:

y = 24e^(-kt)

where:

y is the amount of carbon-14 remaining

e is the base of the natural logarithm

k is the decay constant, calculated by dividing the natural logarithm of 2 by the half-life of carbon-14 (5730 years)

t is the time elapsed

So, k = ln(2)/5730

To find the amount of carbon-14 remaining after 20 millennia (20,000 years), we can plug in the values:

t = 20,000 years

y = 24e^(-k * 20,000)

Substituting the value of k:

y = 24e^(-ln(2)/5730 * 20,000)

y = 24 * e^(-0.000011 * 20,000)

y = 24 * 0.038

y = 0.912 mg

So, the amount of carbon-14 remaining after 20 millennia is 0.912 mg.
