Since 8km is for 1 centimeter, we multiply 8 by 24 to find how many kilometers there are for 24 centimeters. 8 * 24 is 192 so B.) is your answer.

a. The inverse of a linear transformation T₁,  which is obtained is:

T₁⁻¹(x,y) = (37x - 9y)/2 , (-8x + 2y)/2

b. The inverse of T₂ does not exist.

c. Entering the values of T₁ into the equations gives:  

d. Entering the values of T₂ into the equations gives:  

a. To find the inverse of a linear transformation T₁ , we need to solve the system of equations:

2x + 9y = a
8x + 37y = b

We can use the determinant of the matrix associated with this system to find the inverse:

\(\left[\begin{array}{cc}2&9\\8&37\end{array}\right]\)

The determinant Δ is:

Δ = (2)(37) - (9)(8)

Δ = 74 - 72

Δ =  2

The inverse of T₁ is:

T₁⁻¹(a,b) = (1/2)(|37 -9| |a|) = (37a - 9b)/2 , (-8a + 2b)/2

T₁⁻¹(x,y) = (37x - 9y)/2 , (-8x + 2y)/2

b. To find the inverse of a linear transformation T₂, we need to solve the system of equations:

x + z = a
x + y = b
y + z = c

We can use the determinant of the matrix associated with this system to find the inverse:

\(\left[\begin{array}{ccc}1&0&1\\1&1&0\\0&1&1\end{array}\right]\)

The determinant Δ is:

Δ =  (1)(1)(1) + (0)(0)(1) + (1)(1)(0) - (1)(0)(0) - (1)(1)(1) - (0)(1)(1)

Δ = 1 - 1

Δ = 0

Since the determinant is 0, the inverse of T₂ does not exist.

c. To find x and y given T₁(x,y) = (5,-1), we can plug in the values into the equations for T₁:

2x + 9y = 5
8x + 37y = -1

We can use substitution to solve for x and y. From the first equation, we can solve for x:

x = (5 - 9y)/2

Plugging this into the second equation:

8(5 - 9y)/2 + 37y = -1

Simplifying:

20 - 36y + 37y = -2

y = -22

Plugging this back into the first equation to solve for x:

x = (5 - 9(-22))/2

x = 101/2

d. To find x, y, and z given T₂(x,y,z) = (5,-3,-1), we can plug in the values into the equations for T₂:

x + z = 5
x + y = -3
y + z = -1

We can use substitution to solve for x, y, and z. From the first equation, we can solve for x:

x = 5 - z

Plugging this into the second equation:

5 - z + y = -3

Simplifying:

y = -8 + z

Plugging this back into the third equation:

-8 + z + z = -1

2z = 7

z = 7/2

Plugging this back into the equations to solve for x and y:

x = 5 - 7/2

x = 3/2

y = -8 + 7/2

y = -9/2

Step-by-step explanation:

Answer:

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7

Answer:

See details below:

Step-by-step explanation:

We can start with the biggest factors and work our way down to see how arrive at 4 * 25.

In this case, the first part of the tree would be 50 * 2.

2 is prime, but 50 is not and thus must be factored.

Two possible factors of 50 are 2 and 25.

The 25 is not a prime number and must be factored further.

Two possible factors of 25 are 5 and 5.

Thus, the prime factorization of 100 is 2*2*5*5.

Then to simplify, we can combine the similar factors:  (2*2) * (5*5) = 4*25

Kim earned \($159.22\) for the week by selling 829 newspapers.

Kim's earnings for the week, we need to use the information provided in the problem.

She is paid a base salary of \($10\) per week, and she also earns \($0.18\) for each newspaper she sells.

She earned for selling 829 newspapers, we need to multiply the number of newspapers by the amount she earns per newspaper, and then add her base salary:

Earnings from newspapers sold = 829 × \($0.18\)

= \($149.22\)

Earnings for the week = \($149.22 + $10\)

=\($159.22\)

It's worth noting that if Kim didn't sell any newspapers, her earnings for the week would still be \($10\), which is her base salary.

She will always have some income even if she has a slow week and doesn't sell many newspapers.

The more newspapers she sells, the higher her total earnings will be.

For a cost function, C(x) = 36100 + 800x + x²

a) The cost at the production level 1250 is equal to 2,598,600.

b) The average cost at the production level 1250 is equal to 2,078.88.

c) The marginal cost at the production level 1250 is equal to 3300 $/unit.

d) The production level, x = 60 that will minimize the average cost.

e) The minimal average cost is equals the 1,461.67.

Let consider C(x) be a total cost function where x is quantity of the product, then,

We have a cost function is written as C(x) = 36100 + 800x + x²

a) The cost at production level 1250, that is x = 1250 is equals to

=> C( 1250) = 36100 + 800× 1250 + 1250²

= 2,598,600

b) The average cost at the production level 1250, that is AC(x) \(= \frac{36100 + 800x + x²}{x}\)

\(= \frac{36100}{x} + 800 + x\)

Plug the value x = 1250

\(= \frac{36100}{1250} + 800 + 1250\)

= 2,078.88

c) The marginal cost at the production level 1250 is equal to the derivative of

\(\frac{dC(x)}{dx }\), evaluated for x = 1250,

\(\frac{dC(x)}{dx }\) = C'(x)

= 800 + 2x

C'(1250) = 800 + 2× 1250 = 3300$/unit

d) As we know the average cost of the total cost function is,

\( A C(x) = \frac{36100}{x} + 800 + x\)

Compute the critical point for minimizing the average cost, differentating the above equation, \(AC′(x)= \frac{ d(\frac{36100}{x} + 800 + x)}{dx}\)

\(= \frac{- 36100}{x²} + 1\)

For critical value plug AC'(x) = 0

\(\frac{- 36100}{x²} + 1 = 0\)

=> x² - 3600 = 0

=> x = ± 60

As the quantity must be positive so x = 60.

e) Now we will compute the minimum average value at x = 60,

\( A C(60) = \frac{36100}{60} + 800 + 60\)

= 1,461.67

Hence, required value is 1,461.67.

The interquartile range of the number of jumps of the 10 students during the competition is 38.

The interquartile range is the difference between the third quartile and the first quartile. The interquartile range is used to determine the variation of a data set.

Th first step is to determine the median of the first half of the dataset. The median of the first half is the first quartile.

First half of the data set: 30, 36, 38, 45, 57

Median = first quartile =  38

The next step is to determine the median of the second half of the dataset. The median of the second half is the third quartile.

Second half of the data set: 60, 77, 86, 88, 88

Median : third quartile =  86

Interquartile range = third quartile - first quartile

The equation of the translated parent function f(x) - e* where it is translated 1 unit right and 2 units down is:

fx) - e*(x-1)-2

Option A is close, but the signs are incorrect. Option B has the correct horizontal translation but the wrong vertical translation. Option C has the correct vertical translation but the signs for the horizontal translation are incorrect. Option D has incorrect signs for both the horizontal and vertical translations.
Hi! I'd be happy to help you with this question. The given parent function is f(x) = e^x, and we need to translate it 1 unit to the right and 2 units down. To translate a function horizontally, we replace x with (x - h) where h is the number of units to shift. To translate a function vertically, we add or subtract a constant, k, from the function.

For our case, we have h = 1 (1 unit to the right) and k = -2 (2 units down). So, the translated function will be:

f(x) = e^(x - 1) - 2

Comparing this with the given options, the correct answer is:

d. f(x) = e^(x - 1) - 2

The Area of the figure ,composing of a square and four semicircles is 832.7 sq. units

The Length of the side of the square is 18 units which is also the diameter of the semicircle.

So, The Area of square is Length * Length = 18*18 = 324 sq. units

Now, the radius of semicircle = 0.5(diameter)= (0.5)*18 = 9 units

The area of semicircle = half of area of circle = (0.5)3.14(radius)(radius)

The area of one semicircle = (0.5)3.14(9)(9)

The area of one semicircle = 127.17

The Total area of figure consists of 4 semicircles and one square

So, Total area = 4(area of 1 semicircle) + area of square

Total area = 4(127.17) + 324

Total area =  832.68 sq. units

rounding off the total area = 832.7 sq. units

The integral of Im z², C counterclockwise around the triangle with vertices 0, 6, 6i is 0, the first method to solve this problem is to use the fact that the integral of Im z² over a closed curve is 0.

This is because the imaginary part of z² is an even function, and the integral of an even function over a closed curve is 0.

The second method to solve this problem is to use the residue theorem. The residue of Im z² at the origin is 0, and the residue of Im z² at infinity is also 0. Since the triangle with vertices 0, 6, 6i does not enclose any other singularities, the integral is 0.

The imaginary part of z² is given by

Im z² = z² sin θ

where θ is the angle between the real axis and the vector z. The integral of Im z² over a closed curve is 0 because the imaginary part of z² is an even function. This means that the integral of Im z² over a closed curve is the same as the integral of Im z² over the negative of the closed curve.

The negative of the triangle with vertices 0, 6, 6i is the triangle with vertices 0, -6, -6i, so the integral of Im z² over the triangle with vertices 0, 6, 6i is 0.

The residue theorem states that the integral of a complex function f(z) over a closed curve is equal to the sum of the residues of f(z) at the singularities inside the curve. The only singularities of Im z² are at the origin and at infinity.

The residue of Im z² at the origin is 0, and the residue of Im z² at infinity is also 0. Since the triangle with vertices 0, 6, 6i does not enclose any other singularities, the integral is 0.

Therefore, the integral of Im z², C counterclockwise around the triangle with vertices 0, 6, 6i is 0.

Descartes' Rule and the Fundamental Theorem of Algebra are useful tools in predicting the number of complex roots and determining the number of possible positive and negative real roots of a polynomial.

Descartes' Rule of Signs states that for a polynomial with real coefficients, the number of positive real roots is equal to the number of sign changes in the coefficients or is less by an even number, while the number of negative real roots is equal to the number of sign changes in the coefficients or is less by a multiple of 2.

The Fundamental Theorem of Algebra states that a polynomial of degree n has exactly n complex roots, taking into account their multiplicities. This means that even if some roots are repeated, the total count remains n.

To predict the number of complex roots for a polynomial, we can use the Fundamental Theorem of Algebra. If the polynomial has a degree of n, we can conclude that there will be n complex roots.

Example 1:

Consider the polynomial f(x) = x^3 - 2x^2 + x - 2. It is a cubic polynomial, so according to the Fundamental Theorem of Algebra, it will have 3 complex roots.

Example with the polynomial g(x) = x^4 - 5x^2 + 4x - 1. It is a quartic polynomial, so it will have 4 complex roots.

In both examples, the predicted number of complex roots is determined by the degree of the polynomial. The Fundamental Theorem of Algebra guarantees that the total number of complex roots will match the degree of the polynomial.
