On a piece paper, graph f(x)=2 x (0.5)^x. Then determine which answer choice matches the graph you drew.

The point on the curve with a slope of −93–√2 is (2, 0.43)

Given x(t) = 2 sin(8t) and y(t) = −9 cos(8t)

We are asked to determine the points on the curve with a slope of −93–√2.

Now, x/2 = sin(8t)   --(1)

       -y/9 = cos(8t)   --(2)

Squaring and adding equations (1) and (2)

               (x/2)² + (-y/9)² = sin²(8t) + cos²(8t)

                   x²/4 + y²/81 = 1

Differentiating both sides

                 x/2 + (2y/81) (dy/dx) = 0

Given slope = dy/dx = −93–√2

                 (2sin(8t))/2 + (2(−9 cos(8t))/81)(-93 - √2) = 0

                   sin(8t) + (2/9)cos(8t)(93 + √2) = 0

Solving for t and taking care of 0 ≤ t <π/8

                 we get t = 11.59°, 34.09°, 79.09°......

But only t within the given range is t = 11.59°.

Now, x = 2sin(8 x 11.59°) = 2

and y = -9 cos(8 x 11.59°) = 0.43

Hence, the point on the curve with a slope of −93–√2 is (2, 0.43)

A. In a case whereby Tyler’s brother earns a commission. He makes 2.5% of the amount he sells. Last week, he sold $1000 worth of shoes  his commission is  $22.50

B. The percentage markup was  $30

C.In a case whereby  aTyler’s brother earns $14 per hour. The store offers him a raise—a 5% increase per hour the amount Tyler’s brother make per hour is 12.60

The concept that will be used here is commision and percentage.

A. Therefore, a commission is often a percentage of a sale. Suppose, for illustration, that I own a cookie company. I take you on as a seller and inform you that you will receive a 10% commission for each box you sell. Given that the box of cookies costs $5.00,

you would get $5.00 * (.10), or $0.50, for each successful box you sell. Therefore, if you sell 200 boxes in a week and earn $0.50 per box, your total commission would be $0.50 * 200 = $100!

Thus, Tyler's brother sold shoes valued a total of $900. In the event that he earns a 2.5% commission, his reward will be [ $900 * (0.025) ]= $22.50 for his work.

B. The Markup on the shoe =Amount sold - purchase price

Markup = [$80 - $50]

= $30

Percentage Markup is :$30/50  *100 =  60%

C. 5% of 12  can be calculated as 5/100*12=  0.60

The probability that a state is occupied by an electron at

i)1kt:0.5

ii) 3kt: 0.7

ii)5kt: 0.9

The probability that a state is occupied by an electron at any given temperature above the Fermi level is calculated using the Fermi-Dirac statistics. This equation states that the probability of a state being occupied is equal to 1/(1+exp(-(E-EF)/KT)), where E is the energy of the state, EF is the Fermi level energy, and KT is the product of Boltzmann's constant and the temperature in Kelvin.

Thus, for a temperature of 1kt above the Fermi level, KT = 1. By plugging these values into the equation, we can calculate that the probability of a state being occupied is 0.5. For a temperature of 3kt and 5kt above the Fermi level, KT = 3 and 5, respectively. Using these values, the probability of a state being occupied at 3kt and 5kt above the Fermi level is 0.7 and 0.9, respectively.

A dilation of a figure is a transformation that changes the size of a figure but not its shape. To find the scale factor required to dilate a trapezoid to have a different area, we need to know the formula for the area of a trapezoid and the desired area. In this conext, the area would be 100 * scale factor^2

The formula for the area of a trapezoid is:

Area = (base1 + base2) * height / 2

Let's say the original trapezoid has an area of 100 square units and the desired area is "A" square units.

The scale factor required to dilate the trapezoid to have an area of "A" square units is given by the equation: 100 = (base1 + base2) * height / 2

100 * 2 / (base1 + base2) = height

200 / (base1 + base2) = height

To find the new area:

A = (base1 + base2) * height / 2

A = (base1 + base2) * 200 / (2 * (base1 + base2))

A = 200 * height / 2

A = 100 * scale factor^2

So, the scale factor required to dilate the trapezoid to have an area of "A" square units is given by the equation:

Scale factor = sqrt(A/100)

The statement "For midsized cars, lower driving speeds seem to yield lower miles per gallon" indicates a negative relationship between driving speed and fuel efficiency.

This statement means that as the driving speed increases, the fuel efficiency decreases and vice versa. This relationship is likely due to the increase in air resistance and engine drag as driving speed increases, which leads to a decrease in fuel efficiency.

This relationship can be seen in the context of the physics of motion and energy, where energy is conserved, and an increase in one form of energy, such as kinetic energy, is accompanied by a decrease in another form of energy, such as thermal energy.

The fixed fee for Company 1 is equal to $5.5.

The fixed fee for Company 2 is equal to $9.15625.

A statement which is true is: A. Company 1's rate per pound is twice the rate per pound of Company 2.

In Geometry, the rate of change of any straight line simply refers to its gradient or slope and it can be calculated by using this mathematical expression;

Rate of change (slope), m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)

Based on the weight of the package for Company 1, the constant rate per pound is given by:

Rate of change (slope), m = (14.50 - 9.25)/(6 - 2.5)

Rate of change (slope), m = 5.25/3.5

Rate of change (slope), m = 1.5.

At data point (2.5, 9.25), an equation for the fixed fee for Company 1 can be calculated in point-slope form as follows:

y - y₁ = m(x - x₁)

y - 9.25 = 1.5(x - 2.5)

y = 1.5x - 3.75 + 9.25

y = 1.5x + 5.5

Therefore, the fixed fee is $5.5.

Based on the weight of the package for Company 2, the constant rate per pound is given by:

Rate of change (slope), m = (7.25 - 6.5)/(2 - 1)

Rate of change (slope), m = 0.75/1

Rate of change (slope), m = 0.75.

At data point (1, 6.5), an equation for the fixed fee for Company 1 can be calculated in point-slope form as follows:

y - y₁ = m(x - x₁)

y - 6.5 = 0.75(x - 1)

y = 0.75x - 0.75 + 6.5

y = 0.75x + 5.75

Therefore, the fixed fee is $5.75.

Asymptotes - (x - 3)/2 - 1 and -(x - 3)/2 - 1

What is a hyperbola?

One sort of smooth curve that lies in a plane is called a hyperbola, and it has two connected components or branches that are mirror reflections of one another and seem like two infinite bows. A set of points is referred to as a hyperbola if the difference between their distances from two foci is constant.

The given equation is - [(x - 3)²/16 - (y + 1)²/4] = 1

The equation of a hyperbola is  [(x - h)²/a² - (y - k)²/b²] = 1, where (h,k) is the centre, a and b are the lengths of the semi-major and the semi-minor axes.

In the equation h = 3, k = -1, a = 4 and b = 2.

The standard form is [(x - 3)²/4² - (y + 1)²/2²] = 1.

The vertex form is [(x - 3)²/16 - (y + 1)²/4] = 1.

The general form is x² - 6x - 4y² - 8y - 11 = 0.

The vertices of hyperbola is given as (h+a,k) and (h-a,k) which are the two bending points of the hyperbola with centre (h,k).

Vertices = (3+4,-1) and (3-4,-1)

Vertices = (7,-1) and (-1,-1)

For a right-left facing hyperbola, the Foci (focus points right) are defined as (h+c,k) and (h-c,k) where c = √(a² + b²) is the distance from the center (h,k).

c = √(4² + 2²)

c = √16 + 4

c = √20

c = 2√5

So the foci is -

Foci = (3 + 2√5 , -1) and (3 - 2√5 , -1).

The asymptotes are the lines the hyperbola tends to at ±∞.

For right-left hyperbola the asymptotes are y = ± b/a(x - h) + k.

y = ± 2/4(x - 3) + -1.

y = (x - 3)/2 - 1 and -(x - 3)/2 - 1

Therefore, the graph for the hyperbola is plotted.

The probability of two or more events happening simultaneously is 0.36.

The probability of two or more events happening simultaneously depends on the number of events and the type of relationship between them. If the events are independent, meaning that the occurrence of one event does not affect the probability of the other event happening.

The probability of two or more events happening simultaneously can be calculated using the formula for the sum of probabilities:

P(A or B) = P(A) + P(B) - P(A and B)

Where A and B are two events. If we have n independent events with the same probability of 20%, the probability of two or more events happening simultaneously can be calculated as follows:

P = 1 - P(none of them happen) = 1 - (1 - 0.2)ⁿ

For n = 2, we have:

P = 1 - (1 - 0.2)² = 1 - 0.64 = 0.36

So, the chance that two events with a 20% probability will happen simultaneously is 36%. The chance for three or more events is even higher.

It's important to note that if the events are dependent, the calculation will be different. The relationship between the events can significantly impact the final probability.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

Given:

Rodrigo is an ichthyologist, or a scientist who studies fish.

When he first started monitoring the sturgeon population of Lavender Lake, he estimated there were 600 sturgeon in the lake.

One year later, Rodrigo estimated the population had decreased to 510. He expects the sturgeon population to continue decreasing each year.

The exponential decay function:

y = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

So, y = 600(1 - r)ˣ.

One year later,
