How do you find the domain and range of a function F XY?

Answer:

When  x =  -16, y = -1.

Step-by-step explanation:

Let's plug in y = -1 into this equation

-1 = 1/4x + 3

Now, we need to solve the equation for x. To do so, we want x to be by itself on one side of the equation. We will use inverse operations to get the x by itself. First, subtract 3 from either side to under the +3 on the right side of the equation.

-1 - 3 = 1/4x + 3 - 3

-4 = 1/4x

Next, we will divide by 1/4 to undo the *1/4. Dividing by 1/4 is the same as multiplying by 4, so we will multiply each side by 4.

-4 * 4 = 1/4x * 4

-16 = x

Answer:

-6.50

Step-by-step explanation:

The zeros of the function are the x-values that make f(x) equal to zero. To find the zeros of this quadratic function, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 20, and c = 46. Plugging in the values:

x = (-20 ± √(20² - 4 * 2 * 46)) / 2 * 2

x = (-20 ± √(400 - 184)) / 4

x = (-20 ± √216) / 4

x = (-20 ± √6 * √6) / 4

x = (-20 ± 6) / 4

So the zeros are x = (-20 + 6) / 4 = (-14) / 4 = -3.5 and x = (-20 - 6) / 4 = -26 / 4 = -6.5.

Rounding to the nearest hundredth, the zeros are approximately -3.50 and -6.50.

The highest point of the arch is 9/10 feet above the ground.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

To find the highest point of the arch, we need to find the vertex of the parabola defined by the function h = -1/5x²+x.

The vertex of a parabola represented by the equation y = ax² + bx + c is given by

(-b/2a, c-b²/4a)

The vertex of the parabola is given by (-1/2×1/5, h-1/4×1/25) = (1/10, h-1/100)

Now substitute the value of h from the given equation:

h=-1/5x²+x

So, the value of h at the vertex is (1/10, -1/5 × (1/10)²+1/10-1/100) = (1/10, 9/100)

Thus, the highest point of the arch is 9/10 feet above the ground.

Answer:

Here is the inequality graphed. The circle isn't filled in and the point is at 1.4  just in case you cannot see it.

Step-by-step explanation:

The probability that each of the players will have an Ace is 0.1055. The result is obtained by dividing the ways to place Aces for each player by the total ways.

The four suits for a standard deck of 52 cards are hearts, diamonds, clubs, and spades of 13 cards each. The hearts and diamonds are red. While, the clubs and spades are black. The 13 cards are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King.

The 52 cards are randomly distributed to 4 players. So, each players will get 13 cards.

Find the probability that each of them will have an Ace!

When we distribute 13 first cards, the rest cards are 39. After 13 second cards, the rest are 26 cards, an so on. Without discerning the suits, the ways to place Aces so that each player will get an Ace is

n(A) = 13⁴

There are 4 Aces in 53 cards. The total ways to place the Aces is

[tex]n(S) = \binom{52}{4}[/tex]

The probability that each player will have an Ace would be

[tex]P = \frac{n(A)}{n(S)} = \frac{13^{4} }{ \binom{52}{4}} = \frac{28561}{270725} \approx 0.1055[/tex]

Hence, the probability that each player will get an Ace is 0.1055.

The given equation is of form : x1+x2+...+xn = k, where x1>=m1, x2>=m2 and so on, this is typical equation which can be mapped to questions like :

Q)You have n candies and you want to distribute it to k children where each child gets at least m candies or in other words n same candies in k different boxes, where each box must have certain number of candies.

In your case m1=m2=...=mn= 0(or 1 based on your definition of natural numbers, lets first solve for condition where lower bound is 0).

This solution is simple, (n-1+k C k) which gives (3-1+11 C 11) = 78 as answer.

Now, the case for which we start natural numbers with 1 :

First we need to reduce it to previous formula. This can be done by making the lower bounds as 0 or to say lets first distribute minimum number of candies to children.Now we are left with k-m1-m2...-mn candies, so equation reduces to :

x1+x2+...+xn = k-m1-m2...-mn

or in your case x1+x2+x3 = (11-3) = 8

Now, using the previous formula (3-1+8 C 8) = 45.Which is required solution.

The height of the rocket is given by the function y = 30t - 5t^2, where y is in meters and t is in seconds.

What does function mean in maths?

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. The input is commonly called the argument and the output is commonly called the value of the function.

We know that the distance between the observer and the rocket is the square root of the height of the rocket squared plus the distance from the observer to the launch point squared.

r = sqrt(y^2 + d^2)

To find the derivative of r with respect to time, we will use the chain rule.

dr/dt = (dr/dy)(dy/dt)

First, we will find dy/dt. Using the power rule for derivatives, we have:

dy/dt = 30 - 10t

Now, we will find dr/dy. Using the definition of r and the power rule, we have:

dr/dy = 1/sqrt(y^2 + d^2)

Now, we can substitute these values into our original equation for dr/dt:

dr/dt = (1/sqrt(y^2 + d^2))(30 - 10t)

We can now substitute the equation for y into this expression:

dr/dt = (1/sqrt((30t - 5t^2)^2 + d^2))(30 - 10t)

simplifying the above expression

dr/dt = (30t-5t^2)(30-10t)/sqroot(30t-5t^2)^2+d^2

So the expression for the derivative of the distance between the observer and the rocket with respect to time is (30t-5t^2)(30-10t)/sqroot(30t-5t^2)^2+d^2

1.The circumferences of the two circles are 220 feet and 126 feet, respectively. We may think of a circle's circumference as a form of "perimeter."

2. The following is the radius of the circle made by Ana's brother in the blue car:

We know that the following formula determines a circle's circumference:

[tex]C=2\Pi \ r[/tex]

Then, we must get r by solving this equation. We know that C is 220 feet and pi is 3.14. Next, we have

[tex]220=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{220}{2 \pi} \\\Rightarrow r=\frac{220}{2 \cdot 3.14} \\\Rightarrow r=35.0318[/tex]

The radius, rounded to the closest tenth, is RB = 35.0 feet (or 35 feet).

3. Using the same method, we can determine the radius of the circle that Ana's sister drew in the green automobile (she travelled 126 feet).

[tex]126=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{126}{2 \cdot 3.14} \\\Rightarrow r=20.0637[/tex]

The equation is y = 0.5 cos (x + π/2) - 1

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

Amplitude = 0.5

Period = pi

Vertical translation: k = -1

According to the unitary method, the store that has the best deal is Store 1 and it cost $202.18

The term unitary method is known as a process of finding the value of a single unit, and based on this value.

Here we have the original prices of the rugs are as follows:

Store #1: $289

Store #2: $265

Store #3: $310

And the discount on each store is written as,

Store #1: 20% (decrease)

Store #2: 12%(decrease)

Store #3: 30%(increase)

And the tax details are given as,

Store #1: 8%

Store #2: 8%

Store #3: no tax.

Then the shipping and the handling charges is $5.9

Then the price for each of the store is calculated as,

=> Store 1 = 289 - [(289 x 0.20) + (289 x 0.08) + 5.9] = 202.18

=> Store 2 = 265 - [(265 x 0.12) + (265 x 0.08) + 5.9] = 206.1

=> Store 3 = 310 + (310 x 0.30) - 5.9 = 397.1

Therefore, the store 1 provides the best deal on the rug.

A'B'/AB = B'C/BC = CA'/CA

=> A'B'/12 = 2/BC = 3/9

We can see many real-life examples of the right angles in our daily life. For example, the corner of a book, edges of the cardboard, etc. Any shape that is a square or a rectangle, will have its corners equal to 90 degrees or right angle. A right angle is hence called a 90-degree angle.
