How do you calculate normal CDF?

The parametric curve defined by x(t) = e^{-t} and y(t) = cos(t) for 0 ≤ t≤ π  is concave down in the interval (c) (0, π) .

The Concavity of a parametric curve is determined by the second derivative of the curve.

To find the second derivative of a parametric curve, we need to differentiate each component of the curve with respect to the parameter t, then differentiate those expressions with respect to t again.

For x(t) = e^{-t} and y(t) = cos(t),

the first derivative w.r.t "t" is x'(t) = -e^{-t} and y'(t) = -Sin(t) ;

the second derivative with respect to t of x''(t) = e^{-t} and  y''(t) = -Cos(t),

Since , y''(t) = -Cos(t) is negative over the interval (0, π), we can conclude that the curve is concave down over that interval.

Therefore, the curve is concave down over that interval (0, π).

Giselle can play at most 6 games in the 6 hours she has available, which meets her second condition but not her first.

To determine the maximum number of games Giselle can play, we need to balance the time available with the number of games she wants to play. Let's assume that each game takes x hours to complete.

Condition a: 10 games = x * 10

Condition b: 6 hours = x * 10

From these two equations, we can solve for x, which represents the time it takes for Giselle to play one game. To do this, we'll divide both sides of the first equation by 10:

10 games / 10 = x * 10 / 10

x = 1 hour

So, it takes Giselle 1 hour to play one game. Knowing this, we can determine how many games she can play in the 6 hours she has available:

6 hours / 1 hour per game = 6 games

Therefore, Giselle can play at most 6 games in the 6 hours she has available, which meets her second condition but not her first.

A constant function is a function that returns the same output every time it is called, regardless of the input. In this case, we want to create a constant function that returns an infinite list of all the natural numbers starting at 0.

Here's an example of how you could implement the nats function in Haskell:

makefile

Copy code

nats :: [Integer]

nats = [0..]

The [0..] syntax creates an infinite list that starts with 0 and continues indefinitely. Every time the nats function is called, it returns this same infinite list, so it's considered a constant function.

Another way to write the nats function is to use the iterate function, which generates a list by repeatedly applying a function to an initial value.

makefile

Copy code

nats :: [Integer]

nats = iterate (+1) 0

In this case, iterate (+1) 0 generates a list by repeatedly adding 1 to 0. The first element of the list is 0, the second element is 0 + 1 = 1, the third element is 1 + 1 = 2, and so on. This generates an infinite list of all the natural numbers starting at 0, which is exactly what we want.

In either case, you can take any number of elements from the nats list by using the take function. For example, take 5 nats would return the first 5 elements of the nats list, which would be [0, 1, 2, 3, 4].

The value of p(0) is the same as the value of q(0) since p and q are both polynomials.

Polynomials are mathematical expressions that are composed of variables and constants and involve only non-negative integer powers of the variables. In this case, p and q are both polynomials. This means that they have the same degree, or highest power of the variable, and the same coefficients. As a result, p(0) will have the same value as q(0). To find the value of p(0), substitute 0 into the function for p. This will give the value of p(0). For example, if p(x) = 3x2 + 2x + 1, then p(0) = 3(0)2 + 2(0) + 1 = 1. This means that p(0) = 1.

Answer: To find the roots of a polynomial equation, we can use various methods, such as factoring, synthetic division, or the quadratic formula. One common method to find the roots of a quartic polynomial (degree 4) is to use the factor theorem, which states that if a polynomial equation has a root "r", then "r" is a factor of the polynomial.

In this case, we can factor 2x^4-26x^2-28 as:

2x^4 - 26x^2 - 28 = 2(x^2 - 7)(x^2 + 4)

So, the roots of 2x^4-26x^2-28 are x = ±√7 and x = ±i√2.

percentage, a relative value indicating hundredth parts of any quantity.

To calculate how much Charlotte would make in a week in which she made $1575 in sales

we first need to calculate her commission:

Commission = 30% × $1575

= $472.50

Total earnings = Guaranteed salary + Commission

= $500 + $472.50

= $972.50

Therefore, Charlotte would make $972.50 in a week in which she made $1575 in sales.

To calculate how much Charlotte would make in a week if she made x dollars in sales, we can use the same method.

Her commission would be:

Commission = 30% ×x

And her total earnings would be:

Step-by-step explanation:

From 148m away at ground level, the angel of elevation to the tower base is 18 degrees. Imagining this as a right angled triangle, if considering the angle of 18 degrees, 148m is the adjacent and the opposite is the height of the hill:

tanA=opposite/adjacent

tan18=opposite/148

opposite = 57.8357059295m

From 148m away at ground level, the angel of elevation to the tower top is 34 degrees. Imagining this as a right angled triangle, if considering the angle of 34 degrees, 148m is the adjacent and the opposite is the height of the hill+the tower:

tanA=opposite/adjacent

tan34=opposite/148

opposite = 120.062515998m

Knowing the height of the hill and tower is 120.062515998m and the height of the hill is 57.8357059295m, we can say the height of the tower is the difference:

120.062515998 - 57.8357059295 = 62.2268100685 m

In the specific case of [0,1], the Intermediate Value Theorem tells us that if k is a real number between f(0) and f(1), then there exists a real number c in the interval [0,1] such that f(c) = k. This means that for any value of k that falls between the values of the function at 0 and 1, there is a point in the interval [0,1] where the function takes on that value.

The expression (x - 10)(60 - 3x) represents Elliot's profit based on the price per key chain, where x is the price in dollars that Elliot charges for each key chain.

The expression can be interpreted as follows:

60 - 3x represents the number of key chains Elliot can make and sell, as it's equal to the maximum amount of money Elliot has minus the total cost of materials for all key chains.

So, (x - 10)(60 - 3x) represents Elliot's total profit, which is equal to the revenue from each key chain multiplied by the number of key chains Elliot can make and sell.

In other words, Elliot's profit is proportional to both the price he charges per key chain and the number of key chains he can sell at that price. The expression captures this relationship and can be used to determine Elliot's profit for different prices.
