The graph of the variation of the height of a person on the Ferris wheel with time, created with MS Excel is attached

The values of the constants in the sinusoidal function, h = a + b·(c·t) are;

a = 30

b = -20

c = π/1.5

What is a sinusoidal function?

A sinusoidal function is a periodic, oscillatory function, that is based on the sine (or cosine) trigonometric ratios.

The diameter of the Ferris wheel = 40 m

The location of the axle above the ground = 30 m

The time it takes to make a complete a rotation = 3 minutes

The formula for modelling the elevation or height, h, of a person above the ground is presented as follows;

h = a + b·cos(c·t)

The details in the question is that at time, t = 0, the person enters the wheel at the lowest point.

Therefore;

At t = 0, h = 30 - 40/2 = 10

h = 10 = a + b·cos(c × 0) = a + b·cos(0) = a + b

a + b = 10

Whereby the height of the axis of the wheel above the ground is a constant, for visibility in the analysis, let the constant a represent the constant height of the axis from the ground, we get;

a = 30

a + b = 10, therefore;

b = 10 - a

b = 10 - 30 = -20

b = -20

At t = 1.5 minutes, the location on the wheel the person enters is at the maximum height on the wheel = 30 + 20 = 50

50 = a + b·cos(1.5·c)

50 = 30 - 20 × cos(1.5·c)

20 × cos(1.5·c) = 30 - 50 = -20

cos(1.5·c) = -1

cos(π) = -1

Therefore; 1.5·c = π

c = π/1.5

The equation is therefore;

h = 30 - 20·cos((π/1.5)·t)

a = 30, b = -20, c = π/1.5

How to do log2 in Excel?

Answers

The syntax for using BASE in Excel is "=LN(number,base)" where "number" is the number for which you want to calculate the logarithm and "base" is the base to which the logarithm should be calculated.

For example, if you want to calculate the logarithm of 10 to the base 2, you would use the formula "=LN(10,2)".

The idea is to express the given integer (20) in terms of either the base or the values given (3 and 5).

Next, since we have the multiplication sign, we use the addition law:

How do you graph the equation y = 1x / 2 + (-5)

Answers

To graph the equation y = 1x / 2 + (-5), you will need to plot several points that satisfy the equation and then connect them with a line.

To do this, you can pick a few values of x, substitute them into the equation to find the corresponding values of y, and then plot these points on the coordinate plane.

For example, if you choose x = -2, the corresponding value of y is (-2) * (1 / 2) + (-5) = -5.5. If you choose x = 0, the corresponding value of y is (0) * (1 / 2) + (-5) = -5. And if you choose x = 2, the corresponding value of y is (2) * (1 / 2) + (-5) = -4.

You can then plot these points on the coordinate plane and connect them with a line to graph the equation.

One computer in a lab is programmed to back up data at the turn of the minute every five minutes. Another computer is programmed to back up data at the turn of the minute every two minutes. Find the number of times in twenty-four hours that the two computers back up data at the same time.

(Assume that the computers do not back up at the start of the 24-hour period.)

Answers

The number of times which the two computers back up at the same time in twenty four hours as required is; 144.

How many times does the computers back up at the same time in 24 hours?

It follows from the task content that the first computer backs up after every five minutes and the second computer backs up every two minutes.

For the given Augmented Matrix ,the correct option is :

A) The solution set has exactly one element.

The exact solution is x = -25 , y = 2 and z = 2.

Augmented Matrix:

An augmented matrix is ​​a means of solving simple linear equations. Coefficients and constant values ​​of linear equations are represented as matrices called augmented matrices. Simply put, an augmented matrix is ​​a combination of two simple matrices along columns. If the first matrix has m columns and the second matrix has n columns, then the augmented matrix has m + n columns.

Now, as given the Augmented matrix:

[1 7 3 -5]

[0 0 0 3]

[0 0 1 2]

[0 1 -1 4]

From this system we get:

y - z = 4       --------------------------- (1)

    z = 2

and, z = 3

and, x + 7y + 3z =-5   ---------------- (2)

Now, Solving the equation with z = 2,

    y - 2 = 4

⇒ y = 6

and, putting y = 6 and z = 2

   x + 7× 6 + 3×2 = -5

⇒ x + 42 + 6 = -5

⇒ x +48 = -5

⇒ x = -53

Therefore, x = -53, y=6 and z =2

Now, for z = 3 in equation (1)

   y - 3= 4

⇒ y = 7

Putting y =7  and z =3, we get:

   x + 7 × 7 + 3×3 = -5

what must be true for (m+p) so that the value of the expression below is negative? Explain.

Answers

For the expression to be negative (m + p) < 2.

What is an expression?

An expression is a group of terms and mathematical symbols which can be evaluated to a given value.

How to determine what must be true for (m+p)?

Since we have the expression -2 + (m + p), we need to determine the value of (m + p) for which the value of the expression is negative.

This implies that the value of the expression is less than zero.

So, we proceed as follows.

Since the expression is -2 + (m + p), for it to be negative, it must be less than zero.

So, -2 + (m + p) < 0

⇒ -2 < -(m + p)

Dividing both sides by -1, we have that

-2/-1 < -(m + p)/-1

2 > (m + p)

(m + p) < 2

So, for the expression to be negative (m + p) < 2.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

y = x² - 5x + 6   be equation (1)

On simplifying the equation , we get

y = x² - 2x - 3x + 6

Taking the common factors of the equation , we get

y = x ( x - 2 ) - 3 ( x - 2 )

On factorizing the equation , we get

y = ( x - 3 ) ( x - 2 )

To find the y intercepts , substitute the value of x = 0 , we get

y = ( 0 - 3 ) ( 0 - 2 )

y = ( -3 ) ( -2 )

A. 8(x² + 2x + (2/2)²) = -3 + 8.

B. x = -1 ±√5/8

E. 8(x² + 2x) = -3.

How to solve the quadratic equation?

In order to solve the given quadratic equation, we would use the completing the square method as follows;

Separating the variables in the quadratic equation from constant, we have the following;

8x² + 16x + 3 = 0

8x² + 16x = -3

By factorizing the common variables in the quadratic equation from constant, we have the following;

8(x² + 2x) = -3 (step 1).

By completing the squares in the brackets and then balancing the expression on the right-hand side, we have the following;

8(x² + 2x + (2/2)²) = -3 + 8 (step 2).

8(x² + 2x + 1) = -3 + 8

8(x + 1)² = 5

Dividing both sides of the quadratic equation by 8, we have the following;

(x + 1)² = 5

Taking the square root of both sides of the quadratic equation, we have the following;

(x + 1) = ±√5/8

x = -1 ±√5/8 (step 3).

Express your answer as a common fraction.

Answers

The probability that the other side of the card is red is [tex]\frac{4}{5}[/tex].

What is conditional probability?

The possibility of an event or outcome happening contingent on the occurrence of a prior event or outcome is known as conditional probability. The probability of the prior event is multiplied by the current likelihood conditional, occurrence to determine the conditional probability.

Suppose you choose a red/black card:

The probability of choosing a red and black card is [tex]\frac{1}{6}[/tex].

Now, since this card has one side as red the probability of seeing a red side in this card is [tex]\frac{1}{2}[/tex].

Suppose you choose a red/red card:

The probability of choosing red and red card is 2/6.

Now, since the card has two red sides the probability of seeing red side in this card is [tex]\frac{2}{2}[/tex] .

Considering we see a single side of the card we have the following probability:

[tex]\frac{2}{6} * \frac{2}{2} = \frac{1}{3}[/tex]

The total probability of seeing a red side is [tex]\frac{1}{12} + \frac{1}{3} = \frac{5}{12}[/tex].

The probability that you pick red-red card and see a red side is [tex]\frac{1}{3}[/tex].

So, the conditional probability of both red sides is given as:

[tex]\frac{\frac{1}{3} }{\frac{5}{12} } = \frac{4}{5}[/tex]

What are Parallel Lines Cut by Transversal?

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
