Claudia is walking at a constant speed in front of a motion sensor. After 1 s she is 2. 5 m from the sensor. 2s later and she is 4. 0 m from the sensor. Find the equation in the form d=mt+b that describes her motion

Answers

Answer 1

The distance is 5.5 meters from the sensor.

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.

Let us assume that d means distance and t means time.

When t = 1, d = 2.5

When t = 3, d = 4

d = mt + b

2.5 = m + b [t = 1]

4.0 = 3m + b [t = 2]

1.5 = 2m [subtract]

m = .75 = slope

b = 1.75 = d-intercept

d = .75t + 1.75

d = 15/4 + 7/4 [t = 5]

d = 22/4 = 5.5 m from sensor

Thus, the distance is 5.5 meters from the sensor.

The rhombus have the meeting of the side length CD to be equal to 15.

What is a rhombus

A rhombus is a two-dimensional geometric shape with four equal sides and four equal angles, but the angles are not necessarily 90 degrees. It is a type of parallelogram.

Since all the sides of the rhombus are equal, then;

AD = AB = CD

4x - 9 = 2x + 3 = CD

we can solve for x as follows:

4x - 9 = 2x + 3

4x - 2x = 9 + 3 {collect like terms}

2x = 12

x = 12/2 {divide through by 2}

x = 6

so;

AD = 4(6) - 9

AD = 15.

Therefore, the rhombus have the meeting of the side length CD to be equal to 15.

consider the cardiod r=1 sintheta determine the values wehre teh curve has a horizontal and vertical tangents

Answers

So, if the curve has a horizontal tangent, the values are = k, where k is an integer, and where the curve has a vertical tangent, the values are = (2k + 1)/2, where k is an integer.

What is cardiod?

A cardiod is a curve defined by the equation r = 1 + cos(θ), where r is the radial coordinate and θ is the angular coordinate. The equation can be re-written as r = 1 + cos(θ) = 1 + 2cos^2(θ/2) for 0 <= θ <= 2π. A curve has a horizontal tangent when its derivative with respect to θ is equal to zero, which means the slope of the tangent line is 0. The derivative of r with respect to θ is dr/dθ = -sin(θ). Thus, the curve has a horizontal tangent when -sin(θ) = 0, or θ = kπ, where k is an integer.

Here,

A curve has a vertical tangent when its second derivative with respect to θ is equal to zero, which means the rate of change of the slope is 0. The second derivative of r with respect to θ is d^2r/dθ^2 = -cos(θ). Thus, the curve has a vertical tangent when -cos(θ) = 0, or θ = (2k + 1)π/2, where k is an integer.

So, the values of θ where the curve has a horizontal tangent are θ = kπ, where k is an integer, and the values of θ where the curve has a vertical tangent are θ = (2k + 1)π/2, where k is an integer.

The x-intercepts are approximately x = 1.305, 5.695. These are the x-coordinates where the parabolic function crosses the x-axis.

What is parabola?

A parabolic function is a type of mathematical function that describes a parabolic curve or parabola. A parabola is a U-shaped curve that is symmetrical about its axis of symmetry.

The equation y = x^2 - 3x - 7 represents a parabolic function with its vertex located at (-3/2, -7). To find the x-coordinates of the x-intercepts (also known as the roots or zeros), we need to solve the equation x^2 - 3x - 7 = 0. This can be done using various methods, such as the quadratic formula or factoring.

Using the quadratic formula, the x-intercepts can be found as follows:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -3, c = -7, and √ represents the square root symbol.

So,

x = (-(-3) ± √((-3)^2 - 4(1)(-7))) / 2(1)

x = (3 ± √(9 + 28)) / 2

x = (3 ± √37) / 2

Hence, the x-intercepts are approximately x = 1.305, 5.695. These are the x-coordinates where the parabolic function crosses the x-axis.

if h(x)=∫sin2x−π4csc(t4 1)ⅆt for −π4≤x≤π4, then h′(x)=

Answers

The derivatives of h(x) is h'(x) = √2 csc ([tex]x^4[/tex] + 1).

We have,

To find h'(x), we need to take the derivative of h(x) with respect to x using the Fundamental Theorem of Calculus.

Given that h(x) = ∫sin(2x - π/4) csc([tex]x^4[/tex] + 1) dt, we can rewrite it as:

h(x) = ∫[a, x] sin(2t - π/4) csc([tex]t^4[/tex] + 1) dt

Now, we'll apply the Fundamental Theorem of Calculus:

h'(x) = d/dx [∫[a, x] sin(2t - π/4) csc([tex]t^4[/tex] + 1) dt]

Using the Leibniz integral rule, we have:

h'(x) = sin(2x - π/4) csc([tex]x^4[/tex] + 1) - sin(2a - π/4) csc([tex]a^4[/tex] + 1)

However, we need to evaluate this derivative at x = π/4 and x = -π/4, so we substitute these values in:

h'(π/4) = sin(2(π/4) - π/4) csc((π/4)^4 + 1) - sin(2a - π/4) csc([tex]a^4[/tex] + 1)

h'(-π/4) = sin(2(-π/4) - π/4) csc((-π/4)^4 + 1) - sin(2a - π/4) csc(a^4 + 1)

Since the derivative is evaluated at the endpoints, the term with sin(2a - π/4) cancels out in both expressions.

Therefore, the derivative simplifies to:

h'(x) = sin(π/4) csc([tex]x^4[/tex] + 1) - sin(-π/4) csc([tex]x^4[/tex] + 1)

simplifying further:

h'(x) = (√2/2) csc([tex]x^4[/tex] + 1) + (√2/2) csc([tex]x^4[/tex] + 1)

Combining like terms, we have:

h'(x) = (√2/2) (csc([tex]x^4[/tex] + 1) + csc([tex]x^4[/tex] + 1))

h'(x) = (√2/2) (2csc([tex]x^4[/tex] + 1))

Finally, simplifying:

h'(x) = √2 csc([tex]x^4[/tex] + 1)

Therefore,

The derivatives of h(x) is h'(x) = √2 csc([tex]x^4[/tex] + 1).

A kite is a 2-dimensional geometric shape with two pairs of equal-length sides that meet at right angles. It has two diagonals, one longer and one shorter. To find the area of a kite, we use the formula:

Area = (diagonal1 * diagonal2) / 2

In this case, the dimensions given are 20 and 25, which we can assume are the lengths of the two diagonals of the kite.

Let's call the shorter diagonal d1 (which is 20) and the longer diagonal d2 (which is 25).

Using the formula, we can find the area of the kite:

Area = (d1 * d2) / 2 = (20 * 25) / 2 = (500) / 2 = 250 square meters

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is - (5x² + 25x + 20) / 7x

The other two expression are -

(x² + 2x + 1) / (7x² + 7x)

Let the unknown expression be x.

So according to the question -

(x² + 2x + 1) / (7x² + 7x) × x = (5x² + 25x + 20) / 7x

Cross multiply the polynomials -

x = [(5x² + 25x + 20) / 7x] × [(7x² + 7x) / (x² + 2x + 1)]

Here, it can be seen that (x² + 2x + 1) is the expansion of (x + 1)² and (7x² + 7x) = 7x (x + 1).

Substitute these values into the equation -

x = [(5x² + 25x + 20) / 7x] × [7x (x + 1) / (x + 1)²]

Simplify the equation -

x = (5x² + 25x + 20) / (x + 1)

Here, it can be seen that (5x² + 25x + 20) is the expansion of 5 (x + 4) (x + 1).

Substitute these value into the equation -

x = 5 (x + 4) (x + 1) / (x + 1)

Simplify the equation -

x = 5 (x + 4)

Multiply the numerator and denominator by (x - 1) -

x = 5 (x + 4) (x - 1) / (x - 1)

x = 5x + 20 (x - 1) / (x - 1)

x = 5x² - 5x + 20x - 20 / (x - 1)

x = 5x² + 15x - 20 / (x - 1)

So the unknown expression is 5x² + 15x - 20 / (x - 1).

Verify by substituting -

[(x² + 2x + 1) / (x - 1)] × [(5x² + 15x - 20) / (7x² + 7x)]

Here, it can be seen that (x² + 2x + 1) is the expansion of (x + 1)² and (7x² + 7x) = 7x (x + 1).

Substitute these values into the equation -

[(x + 1)² / (x - 1)] × [5 (x + 4) (x - 1) / 7x (x + 1)]

5 (x + 4) (x + 1) / 7x

Simplify the equation -

5x + 20 (x + 1) / 7x

5x² + 5x + 20x + 20 / 7x

5x² + 25x + 20 / 7x

This expression is equivalent to the original expression.

(d) The height of the tree, in meters, can also be modeled by the function G, given by
G(x) = 100x/(1+x), where x is the diameter of the base of the tree, in meters. When the tree is 50 meters tall, the diameter of the base of the tree is increasing at a rate of 0.03 meter per year. According to this model, what is the rate of change of the height of the tree with respect to time, in meters per year, at the time when the tree is 50 meters tall?
(This was on the no-calculator section of the recently-released AP Calculus AB 2018 exam so I appreciate it if you tried to limit calculator usage)

Answers

(a) H'(6) is the rate of change of the height of the tree at time t=6, which is the slope of the line tangent to the graph of H(t) at that point. Using the data in the table, we can estimate H'(6) to be 3.2 meters per year. This means that, at t=6, the height of the tree is increasing at a rate of 3.2 meters per year.

(b) H'(t) is the rate of change of the height of the tree at time t. Since H'(t) is twice-differentiable, it is continuous and can take any value between its minimum and maximum values. Therefore, there must be at least one time t, for 2 < t < 10, such that H'(t) = 2.

(c) To approximate the average height of the tree over the time interval 2 ≤ t ≤ 10, we can use a trapezoidal sum with the four subintervals indicated by the data in the table. We have:

Subinterval 1: Height = 10; Width = 2 Subinterval 2: Height = 14; Width = 2 Subinterval 3: Height = 18; Width = 3 Subinterval 4: Height = 22; Width = 3

Therefore, the average height of the tree over the time interval 2 ≤ t ≤ 10 can be approximated by the trapezoidal sum:

(10 + 14 + 18 + 22) × (2 + 2 + 3 + 3) / 8 = 196/8 = 24.5 meters.

(d) According to the given model, G(x) = 100x/(1+x), if the tree is 50 meters tall, then the diameter of the base of the tree is x = 2, and the rate of change of the height of the tree with respect to time, in meters per year, is given by G'(2) = 100(1 - 2)/(1 + 2)² = -100/9. Therefore, the rate of change of the height of the tree with respect to time, in meters per year, at the time when the tree is 50 meters tall is -100/9 meters per year.

Find equilibrium solution, at dy/dx = 0.

2y – 3  = 0

y = 3/2

At y = 3/2, the intervals are: ]3/2, ∞[

Put any value of y in this differential equation,

2y – 3  at y = 2

2*2 – 3 = 1 > 0

Thus, slope becomes positive for y > 3/2 .

As, the relation between t and the obtained solution y are increases.

Thus, y < 3/2 : intervals are: ]- ∞, 3/2[

Put any value of y in this differential equation,

2y – 3  at y = 1

2*1 – 3 = -1 < 0

Thus, slope becomes negative for y < 3/2 .

As, the relation between t and the obtained solution y in decreases.

Therefore,  the direction field for the stated differential equation is obtained.

Consider the set of all possible five-card poker hands dealt fairly from a standard deck of fifty-two cards.
How many atomic events are there in the joint probability distribution (i.e., how many five-card hands are there)?

Answers

Total atomic events or count = 2598960

Now, According to the question:

A joint probability distribution represents a probability distribution for two or more random variables. Instead of events being labelled A and B, the condition is to use X and Y as given below. f(x, y) = P(X = x, Y = y) The main purpose of this is to look for a relationship between two variables.

In a deck of cards there are 52 cards having 4 different suits each having 13 different ranks.

In a joint probability distribution of 5 cards hand from a 52 deck of cards is calculated as shown below:

Total atomic events or count = ⁵²C₅

= 52!/5! * (52-5)!

= 52!/5! * 47!

= (48 x 49 x 50 x 51 x 52)/5!

= 311875200/120

= 2598960

Is nitrogen trigonal pyramidal?

Answers

The Nitrogen is commonly considered as a Trigonal Pyramidal molecule .

In a Trigonal Pyramidal arrangement, there are three atoms attached to the central atom at the corners of a triangular plane, with the fourth atom attached above or below the plane.

This molecular geometry is commonly observed in compounds where the central atom has five valence electrons, such as nitrogen in its most common oxidation state of +3.

The Nitrogen in this oxidation state forms compounds like nitrogen triiodide (NI₃) and nitrogen trioxide (NO₃), which have a trigonal pyramidal geometry.
