The height above the ground of a passenger on a Ferris wheel t minutes after the ride begins is modeled by the differentiable function H, where H(t) is measured in meters. Which of the following is an interpretation of the statement H'(7.5) = 15.708?

Proof: If mn is even, then either m = 2k/n or n = 2k/m for an integer k, meaning either m or n must be even.

The following is a direct proof:

The proof shows that if m and n are integers and mn is even, then either m must be even or n must be even. The proof starts by assuming that m and n are integers and that mn is even. It then proceeds to show that one of the factors, either m or n, must also be even.

The proof uses the definition of an even number, which is a number that is divisible by 2, to conclude that if mn is even, then there must be an integer k such that mn = 2k. From this equation, the proof derives the expressions m = 2k/n or n = 2k/m. Since k is an integer, it follows that either m or n must be even, since the result of dividing an integer by another integer is also an integer.

The proof concludes by stating that if mn is even, then either m must be even or n must be even, based on the logical reasoning provided in the proof.

The mid-point of segment AB is X. Ray XY is perpendicular to segment AB. Point L is on ray XY. By congruence of triangle, statements (C) point L is equidistant from point A and B.

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance.

Given that, The mid-point of segment AB is X. Ray XY is perpendicular to segment AB. Point L is on ray XY.

Draw the line segment AL and BL.

In Δ AXL and Δ BXL

AX is equal to BX

XL is common in both Δ

∠AXL is equal to ∠BXL because both are right angle.

So, Δ AXL ≅ Δ BXL

The linear equation that shows how the wind power would need to grow to make this goal is y = 25x + 15

From the question, we have the following parameters that can be used in our computation:

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 15

Using the other point, we have

Height from window = 450ft  the tomato passes your window after 2 seconds and hits the ground 5 seconds after it was thrown. neglect air resistance

Time taken to get from window to ground = 2 secs

V0, initial speed of tomato from drop point = 0 ft/s

Acceleration due to gravity = 32.2 ft/s

When the tomato gets to the observer at the window, its initial speed is no longer 0ft/s but an unknown value, u.

We can apply one of the equations of linear motion to then find this initial velocity at the window using the other parameters given i.e.  

s = ut + [tex]\frac{1}{2}[/tex] [tex]at^{2}[/tex]

= 450ft

t = 2 secs

a = g = 32.2ft/sec

=> 450 = (u*2) + (1/2 * 32.2 * 2^2)

450 = 2u + 64.4

2u = 450 – 64.4

2u = 385.6

=> u = 192.8ft/s

Now that we know this initial velocity, we can use another equation of linear motion to find the height distance between the drop point and the window for the resistance

[tex]v^{2}[/tex] - [tex]u^{2}[/tex] = 2gs

where s = distance between drop point and window

v = 192.8ft/s

u = 0ft/s;

=> [tex]192.8^{2}[/tex] - 0^2 = 2*32.2*s

37171.84 = 64.4s

=> s = 37171.84/64.4

s = 577.20ft

Hence, distance from drop point to the ground, H, will be the addition of s and the height from the window to the ground:

=>H = 577.20 + 450

A scatterplot is the most helpful graph for demonstrating the connection between two quantitative variables.

Data are listed in rising or decreasing numerical order in a raw data listing. The stem-and-leaf presentation gives more depth than the frequency distribution since it may explain individual data values as well as indicate how many are in each group, or stem.

Bins should have the same width and be mutually exclusive and exhaustive.

The sampling distribution  of the sample proportion is approximately normal when the sample size (n) is large and the population proportion (p) is close to 0.5.

This can be mathematically expressed as follows:

[tex]n*p > 10 and n*(1-p) > 10[/tex]

To illustrate, let's say we are sampling from a population with a proportion of 0.3. For the sampling distribution to be approximately normal, the sample size (n) must be larger than 33.3 (n > 33.3). This is because [tex]33.3*0.3 = 10 and 33.3*0.7 = 23.3[/tex].

In other words, the sample size (n) must be large enough so that the product of the sample size (n) and the population proportion (p) is greater than 10 and the product of the sample size (n) and the population proportion (1-p) is also greater than 10. This ensures that the sampling distribution of the sample proportion is approximately normal.

The values of the solution for the triangle is A = 55°, a = 10. 1, b = 12. 3, B = 86.01°, c = 7.68 and C = 39°

The sine rule is used to show the relationship between the sides and angles of a triangle. It is given as:

a/sinA = b/sinB = c/sinC

Where A, B, and C are the angles and a,b, and c are the opposite sides to the angles.

1)

A = 55°, a = 10. 1, b = 12. 3

10 / sin(55) = 12.3 / sinB

B = 86.01°

A + B + C = 180° (angle in triangle)

55 + C + 86 = 180

C = 39

10 / sin(55) = c / sin(39)

c = 7.68

x + y - 2z = 6

When represented as a matrix, we have

Evaluate

D = 1

This means that the matrix is invertible

Next, we calculate the cofactor elements

3 * -2 - 9 * 1 = -15

3 * 1 - 5 * 1 = -2

2 * -2 - 5 * 1 = -9

1 * -2 - 5 * 1 = -7

1 * 1 - 2 * 1 = -1

2 * 9 - 5 * 5 = -7

1 * 9 - 5 * 3 = -6

1 * 5 - 2 * 3 = -1

So, we have

Transpose the adjoint

[tex]A^T = \left[\begin{array}{ccc}-19&9&-7\\15&-7&6\\-2&1&-1\end{array}\right][/tex]

Solve linear system: dx/dt = -2x, dy/dt = -2y. Analyze stability using phase portrait & direction field, identify type of critical point.

The given linear system is:

dx/dt = -2x

dy/dt = -2y

To find the stability or instability of the critical point (0, 0), we need to analyze the behavior of the solutions near that point. To do so, we can linearize the system around (0,0), which means we approximate the system with its tangent line at (0,0). The linearized system is given by:

dx/dt = -2x

dy/dt = -2y

The eigen values of the linearized system are -2 and -2. Since both eigenvalues are negative, the critical point (0,0) is a stable node, which means that any solution that starts close to (0,0) will converge to (0,0) as t approaches infinity. The phase portrait of the system is a set of arrows pointing towards the origin, indicating that all solutions converge to (0,0) as time goes on.
