Answer:

Makennas

Step-by-step explanation:

Area of rectangle = length * width

Area of Karl's garden = 20 * 45 = 900ft²

Area of Makenna's garden = 25 * 40 = 1000ft²

1000 is greater than 900 therefore makennas garden has a greater area than Karls garden

Hence, Makenna's garden is larger in area than Karl's because 1000 > 900.

The number we are looking for is 6/4, which is equivalent to 1 1/2.

Let's start by setting up an equation using algebra. Let x be the number we are trying to find:

x + 1/x = 2 1/12

To solve for x, we need to get rid of the fraction on the right-hand side. We can convert the mixed number to an improper fraction:

x + 1/x = 25/12

Now we can multiply both sides by the denominator (12x) to eliminate the fractions:

12x(x + 1/x) = 12x(25/12)

Simplifying the left-hand side by distributing the 12x:

12x^2 + 12 = 25x

Bringing all the terms to one side:

12x^2 - 25x + 12 = 0

This is a quadratic equation in standard form, which we can solve using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Where a = 12, b = -25, and c = 12. Plugging in these values:

x = (-(-25) ± sqrt((-25)^2 - 4(12)(12))) / 2(12)

x = (25 ± sqrt(529)) / 24

Simplifying the square root:

x = (25 ± 23) / 24

There are two solutions:

x = 2 or x = 6/4

However, we need to check that these solutions satisfy the original equation:

2 + 1/2 = 2 1/2, which is not equal to 2 1/12

6/4 + 4/6 = 25/12, which does satisfy the equation

Therefore, the number we are looking for is 6/4, which is equivalent to 1 1/2.

Answer:

Step-by-step explanation:

If the number solution is none means, the two lines are parallel to each other and they will not intersect

If the number of solution is one, then the two lines intersect at one point which is the solution of the two equations

If there are infinite solutions, then the two lines coincide and so has infinite solutions.

The power of the function is 4 and the leading term will be positive

The zeros of the function are

-2, -1, -1, 1

The zero that occurs at -2 and 1 has a multiplicity of 1. while the zero at -1 have a multiplicity of 2.

The y-intercept is where the graph cuts the y-axis and this is at

Equation of the polynomial function

f(x) = a(x + 2) (x +1)² (x - 1)

using point (0, -2) to solve for a

-2 = a(0 + 2) (0 +1)² (0 - 1)

-2 = a(2) (1)² (--1)

-2 = -2a

a = 1

hence the equation is f(x) = (x + 2) (x +1)² (x - 1)

C. The ratings are not ranks and the units are Likerts.

In the context of student ratings of a course on a 5-point Likert scale, let's analyze the options further:

A. The ratings are ranks and have no units: In a ranking system, the responses would be ordered or ranked in a specific sequence. For example, if the students were asked to rank the course from best to worst, their responses would be assigned specific positions or ranks. However, in a Likert scale, the responses are not based on relative ranking but rather on levels of agreement or disagreement. Therefore, the ratings in this case are not ranks.

B. The ratings are not ranks and have no units: This option is accurate. The responses on a Likert scale do not represent ranks because they do not indicate a specific ordering or hierarchy. Each response on the 5-point Likert scale represents a different level of agreement or disagreement, rather than a rank.

C. The ratings are not ranks and the units are Likerts: This option is the most appropriate choice. Likert scales use response categories (e.g., strongly agree, agree, neutral, disagree, strongly disagree) instead of ranks. The units associated with this variable would be "Likerts" to indicate the scale used.

D. The ratings are ranks and have no units: This option is not applicable since the ratings on a 5-point Likert scale are not considered ranks.

Therefore, option C is the correct answer. The ratings on a 5-point Likert scale are not ranks, and the units associated with this variable are "Likerts" to represent the scale used.

Binary number 11011.10001 can be converted to octal as 33.21, to hexadecimal as 1B.4, and to decimal as 27.15625.

To convert binary to octal, we group the binary digits into sets of three, starting from the rightmost side. In this case, 11 011 . 100 01 becomes 3 3 . 2 1 in octal.

To convert binary to hexadecimal, we group the binary digits into sets of four, starting from the rightmost side. In this case, 1 1011 . 1000 1 becomes 1 B . 4 in hexadecimal.

To convert binary to decimal, we separate the whole number part and the fractional part. The whole number part is converted by summing the decimal value of each digit multiplied by 2 raised to the power of its position. The fractional part is converted by summing the decimal value of each digit multiplied by 2 raised to the power of its negative position. In this case, 11011.10001 becomes (1 * 2^4) + (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) + (1 * 2^-1) + (0 * 2^-2) + (0 * 2^-3) + (0 * 2^-4) + (1 * 2^-5) = 16 + 8 + 0 + 2 + 1 + 0.5 + 0 + 0 + 0 + 0.03125 = 27.15625 in decimal.

The given statement, "Two lines and a transversal form corresponding angles that are congruent," indicates that the lines are parallel. This is known as the Corresponding Angles Postulate or the Corresponding Angles Theorem.

According to the Corresponding Angles Postulate, when a transversal intersects two parallel lines, the corresponding angles formed on the same side of the transversal are congruent. In other words, if the corresponding angles are congruent, then the lines must be parallel.

This implies that the two lines never intersect and maintain a constant distance between each other. When a transversal intersects them, the corresponding angles formed on the same side of the transversal are equal.

If the lines were perpendicular, the corresponding angles formed on the same side of the transversal would not be congruent but rather supplementary, meaning their sum would be 180 degrees.

Therefore, based on the given information, we can conclude that the lines are parallel.

If we want to evaluate this limit

\(\displaystyle \lim_{\text{x}\to1} g(\text{x})\)

Then we need to evaluate these limits as well: \(\displaystyle \lim_{\text{x}\to1} f(\text{x}) \ \text{ and } \lim_{\text{x}\to1} h(\text{x})\)

This is because g(x) is bound entirely by these lower and upper functions. Refer to the squeeze theorem for more information.

To evaluate those two other limits, we simply plug x = 1 into each function.

You should find that:

Each function results in 4 when x = 1. This then extends to the idea that f(x) approaches 4 when x approaches 1; similarly, h(x) approaches 4 when x approaches 1.

Therefore, g(x) must approach this same y value to be contained within both these boundaries. These two boundaries squeeze or pinch g(x) into one possible option here.

We will use the first principle of differentiation, to prove the function.

y = f(x) with respect to its variable x. If this limit exists and is finite, then we say that: Wherever the limit exists is defined to be the derivative of f at x.

Given function cosec x

d(cscx)dx = d(1/sinx)dx

= limh→0 1/sin(x+h)-1/sinx / (x+h)-x

= limh→0 sinx - sin(x + h)/sinxsin(x + h) /h

= limh→0 sinx - sin(x + h) / h sinx sin(x + h)

= limh→0 -(sin(x + h) - sinx)/h sinx sin(x + h)

= limh→0 - (sin(x + h) - sinx)h × 1/limh→0 sinx sin(x + h)

= -cosx × 1/sin2x

= -cosx/sinx × 1/sinx

= -cotx cscx

The instantaneous rate of change of g(x) with respect to x at x = 9 is 4.To find the derivative of the function g(x) at x = 9, denoted as g'(9), we can use the equation of the tangent line given as f'(9) = 4.

The derivative of a function represents its rate of change at a specific point. In this case, the derivative g'(x) at x = 9 is given as 4, which means that at that point, the function g(x) has a slope of 4. The tangent line to the graph of g(x) at (9,32) has this slope of 4, indicating the instantaneous rate of change of g(x) with respect to x at x = 9.

This means that for a small change in x around x = 9, the corresponding change in g(x) is approximately 4 times that of x. Thus, the instantaneous rate of change of g(x) with respect to x at x = 9 is 4, indicating how quickly g(x) is changing at that particular point.

The complementary solution to the homogeneous equation y'' - 36y = 0 is y_c(t) = c1e^(6t) + c2e^(-6t), where c1 and c2 are arbitrary constants.

To find the particular solution to the non-homogeneous equation y'' - 36y = e^(-t), we can guess a particular solution of the form y_p(t) = Ate^(-t), where A is a constant to be determined.

Taking the derivatives, we have y_p'(t) = Ae^(-t) - Ate^(-t) and y_p''(t) = -2Ae^(-t) + Ate^(-t).

Substituting these into the original equation, we get:

(-2Ae^(-t) + Ate^(-t)) - 36(Ate^(-t)) = e^(-t).

Simplifying, we have:

(-2A - 36A) e^(-t) + (A - 36A)t e^(-t) = e^(-t).

To satisfy this equation, we must have:

-38Ae^(-t) + (A - 36A)t e^(-t) = e^(-t).

Comparing the coefficients, we get:

-38A = 1, and

A - 36A = 0.

Solving these equations, we find A = -1/38.

Therefore, the particular solution is y_p(t) = (-1/38)te^(-t).

The general solution to the non-homogeneous equation is y(t) = y_c(t) + y_p(t) = c1e^(6t) + c2e^(-6t) - (1/38)te^(-t).

Since we know that y(t) approaches 0 as t approaches infinity, we can conclude that the constant terms c1 and c2 must be 0. Therefore, the particular solution with the initial conditions y(0) = y0 and y'(0) = y'0 is:

y(t) = -(1/38)te^(-t).

To summarize:

Solution: y(t) = -(1/38)te^(-t).

Initial Conditions: y(0) = y0 and y'(0) = y'0.
