On multiplying (√3+√5)(√3-√5), we get answer as -2

1. Split the radicands in half. A number known as a radicand appears underneath the radical symbol.

2. To multiple radicands, multiply the integers as if they were whole numbers. Always keep the item beneath a single radical sign.

3. Use factoring to exclude any perfect squares from the radicand. To achieve this, check whether any perfect squares have the radicand as a factor.

4. Position the square root of the ideal square before the radical sign. Don't change the second component of the radical symbol.

5. Square the square's root. Sometimes it is necessary to multiply a square root by itself.

The odds in favor of selecting an ace then a face card is 3/52.

Probability is used to determine the odds in favor of an event happening. The odds in favor of an event happening lies between 0 and 1. The greater the odds in favor of the event happening, the closer to one, the probability value would be. In a deck of cards, there are 13 aces and there are 12 face cards

The odds in favor of selecting an ace then a face card = (number of ace cards / total number of cards) x (number of face cards / total number of cards)

(13 / 52) x (12 / 52)

1/4 x 3/13 = 3/52

The transformations needed to sketch the graph of [tex]h(x) = \sqrt[3]{1 - x}[/tex] are described as follows:

Starting with the graph of the basic function [tex]y = \sqrt[3]{x}[/tex], horizontally shift the graph right one unit, and then reflected the graph about the x-axis.

A transformation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

The parent cube root function is given by:

[tex]y = \sqrt[3]{x}[/tex]

To have x -> x - 1, we reflect the function over the y-axis, hence:

[tex]y = \sqrt[3]{-x}[/tex]

To have -x -> 1 - x, we shift it one unit right, hence:

[tex]h(x) = \sqrt[3]{1 - x}[/tex]

The order of the transformations can be reversed, i. e., shift right then reflection.

Thus the correct statement to sketch the graph is given by:

Starting with the graph of the basic function [tex]y = \sqrt[3]{x}[/tex], horizontally shift the graph right one unit, and then reflected the graph about the x-axis.

The value of A is 954

According to the question we have been given that

The equation to be used is :   A = P(1+in)

The values we have been given are ;

       P = 900

       i = 0.03

      n = 2

We need to find the value of A. So to find the value of A we have to put the required values in the equation given to us. Thus,

       A = 900(1+0.03*2)

We will solve according to the BODMAS rule that is we have to first solve the bracket terms.

    A = 900(1 + 0.06)

   A = 900*1.06

    A = 954

Answer:

He would have $100 in his bank account from the information provided

Step-by-step explanation:

Taking into account the definition of probability, the probability for a customer to pick at least one item is 14/15.

Probability is the possibility that a phenomenon or an event will happen, given certain circumstances and it is expressed as a percentage.

The probability of any event A is defined as the ratio between the number of cases in which event A may or may not occur and the total number of possible cases. This is called Laplace's Law:

P(A)= number of favorable cases÷ total number of posible cases

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event is verified when one of the two, A or B, or both occurs and it is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

where the intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B.

In first place, let's define the following events:

So you know:

In this case, considering the definition of union of events, the probability for a customer to pick at least one item is calculated as:

P(M∪F)= P(M) + P(F) -P(M∩F)

P(M∪F)= 17/30 + 5/6 -7/15

P(M∪F)= 14/15

Finally, the probability for a customer to pick at least one item is 14/15.

Aqil have 88 stickers.

Let Ryan have x stickers initially. Then Aqil will have (352-x) stickers. Ryan lost 25% of his stickers i.e., x-(25% of x)

= x- 25x/100

= x-x/4

= 3x/4

After Ryan lost 25% of his stickers, the ratio of Ryan's stickers to Aqil's stickers was 9:4 i.e.,

3x/4 : (352-x) = 9 : 4

⇒ 3x/4/(352-x) = 9/4

⇒3x/4 x 4 = 9 x (352-x)

⇒3x = 3168-9x

⇒3x+9x = 3168

⇒12x = 3168

⇒x = 3168/12

⇒x = 264

The function that relates the sales and the number of muffins is :

S = 2.5 m

The sales amount can be find by the total sales. That is , if there are n products to sell and selling amount is x rs. then we can easily find the total sales by multiplying them and by this total sales we can easily find the number of items sold per units and vice versa.

In the question given,

amount (A) = $ 250.00

Now take any of two values from table ,

Choose any two points and calculate the slope:

slope = [tex]\frac{50 - 20}{20 - 8}[/tex] =  2.5

This is not a true sequence. It just has the same things done to the numerator as to the denominator.

The numerator (top part of the fraction).

Add 3 to the previous numerator's top

So 3 + 3 = 6 which is the numerator of the second term.

15 + 3 = 18 which is the numerator of the seventh term.

So the numerator of the 4th term is 9 + 3 = 12

The Denominator

The difference there is 5

So 21 + 5   = 26

The answer is

12/26

This reduces down to 6/13

A composite function exists as a function that depends on another function. The value for  (f⁰f)(0) = - 4/3

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the two functions be g(x) = 3x + 2 and f(x) = x - 2/3

Now, (f⁰f)(x) = f[f(x)]

f(x) = x - 2/3

(f⁰f)(x) = f( x - 2/3)

simplifying the above equation, we get

(f⁰f)(x) = (x - 2/3) - 2/3  

(f⁰f)(0) = - 2/3 - 2/3

(f⁰f)(0) = - 4/3

Therefore, the value of (f⁰f)(0) = - 4/3.
