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

Hence the value of A is 954.

n-2 is the next larger odd integer if the number represented by n-3 is an odd number.

Parity, in mathematics, is the characteristic of an integer that determines whether it is even or odd. If an integer is a multiple of two, it is even; otherwise, it is odd. For instance, 4, 0, and 82 are even. 3, 5, 7, and 21 are odd numbers in comparison.

Whole numbers that cannot be divided perfectly into pairs are referred to as odd numbers. When two is divided by an odd number, one is left over.

The exponential expression [tex]6^{-3}[/tex]/ [tex]3^{-2}[/tex] * 6² is equivalent to the exponential expression is 3² / [tex]6^{5}[/tex] which is option 2 and not option 1

The Exponential expression given to us is 6^-3/3^-2x6^2 or we can write it as

[tex]6^{-3}[/tex]/ [tex]3^{-2}[/tex] * 6²

There is a rule for solving exponents that when we reciprocate the fractions with exponential powers the signs of powers get changed from negative to positive and positive to negative

for example

[tex]x^{-2}[/tex] is written as [tex]\frac{1}{x^{2} }[/tex]

So, we can write the above  exponential expression as

3² / 6³ × 6²

Also, when two same numbers with different powers then the base remains same and powers get added.

3² / [tex]6^{3+5}[/tex]

3² / [tex]6^{5}[/tex]

So, the exponential expression [tex]6^{-3}[/tex]/ [tex]3^{-2}[/tex] * 6² is equivalent to the exponential expression is 3² / [tex]6^{5}[/tex] which is option 2 and not option 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Convert 9 feet into meters:

Round 2.7432 meters:

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

∴ Ryan have 264 stickers of the total 352 stickers and Aqil will have (352-x) i.e., 88 stickers.

Hence, Aqil have 88 stickers out of the 352 stickers.

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.

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

thus, y = 2.5x

Hence we can say the function that relates the sales and the number of muffins is :

S = 2.5 m

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.

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 linear equation in slope intercept form is y = -2x + 1

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The table represents the given parameters

On the table, we have the following points

(x, y) = (0, 1) and (1, -1)

A linear equation is represented as

y = mx + c

Substitute (x, y) = (0, 1) and (1, -1) in y = mx + c

So, we have

1 = 0 * m + c

-1 = 1 * m + c

This gives

1 = c

-1 =m + c

Rewrite 1 = c as

c = 1

Substitute c = 1 in -1 =m + c

-1 =m + 1

Evaluate

m = -2

Substitute m = -2 and c = 1 in y = mx + c

y = -2x + 1
