The domain of a function is the set of all posible values that its input can take.

To find it, we should analyze the rule of correspondence of the function to see if it includes restrictions over the variable that works as input. In this case, we can see that x appears inside a square root. The expression inside the square root must be greater or equal to 0. Then:

The domain of f is the set of all real numbers x such that:

In interval notation:

Therefore, the domain of the function is:

(1) √15 is an irrational number.

(2) The point graphed on the number line is estimated.

Any number that cannot be stated as a fraction of any integer is considered to be irrational. The decimal expansions of irrational numbers are neither periodic nor do they come to an end. Every number that is transcendental is illogical.

When multiplied by itself, the square root of 15 produces the original integer 15. The square root of 15 is an irrational number since it cannot be expressed in the form of p/q.

Therefore, √15 is an irrational number.

The value of √15 in decimal is 3.87298334621 and hence, the point graphed on the number line is estimated but not an exact answer.

One way to find the blank 1: least common multiple of two numbers is to list their multiples and find the first number that appears in both list.

Another way is to blank 2: multiply the numbers together, and then divide by their blank 3: greatest common factor.

Let the number of ice-cream serving the sisters can buy be "s".

Each serving is $2.80, so the cost of "s" ice-creams will be:

This cost cannot exceed 10 dollars.

10 dollars is the maximum.

So, we can say that "2.80s" is equal to or less than 10.

We write it in inequality notation:

Solving for "s":

So, the logical solution is that the 5 sisters can buy 3 ice-cream servings with their budget.

Let's name the a, b, c

let side a = x

let side b = 4+x

Let side c = hypotenuse = 20

Using the law of pythagoras

opposite² + adjacent² = hypotenus²

x² + (x+4)² = 20²

open the parenthesis

x² + x² + 4x +16 = 400

2x² + 4x + 16 = 400

2x² + 4x + 16 - 400 = 0

2x² + 4x - 384 = 0 --------------------------------(1)

The is now a quadratic equation

so we will solve and find x

Using the formula method

Quadratic formula is

Given the following, (a) 100 (a) 0 (b) 0.1587 (c) 10233 (d) 8.322 (e) 0.0096

The ratio of variance to mean in a sample in n counts from a distribution with a Poisson coefficient ought to correspond to a Chi-square population with n-1 angles of freedom. This test depends on the fact that the mean and variance of the Poisson distribution are identical.

a)

Here for Poisson distribution

Here mean of distribution=μ=λ= 10000

Variance =σ2=λ=   10000  

Standard deviation σ=√λ= 100.000  

Considering that λ is big, we can approximate:

a)

Probability of more than 20000 hits in a day:

Probability =P(X>20000)=P(Z>(20000-10000)/100)=P(Z>100)=1-P(Z<100)=1-1=0

if using ti-84 press -2nd -vars - command :normal cdf(20000,1 2nd EE 99,10000,100)

b)

P(less than 9900 hits):

Probability =P(X<9900)=(Z<(9900-10000)/100)=P(Z<(-1)=0.1587

If using ti-84  press 2nd -vars - command :normalcdf(-1 2nd EE 99,9900,10000,100)  

c)

For top 0.01 or  99th percentile critical value of z=2.33  

Therefore corresponding value=mean+z*std deviation=10233

If using ti-84: press 2nd-vars-invNorm(0.99,10000,100)

d)

Probability of exceeding 10200:

Probability =P(X>10200)=P(Z>(10200-10000)/100)=P(Z>2)=1-P(Z<2)=1-0.9772=0.0228

Therefore expected number of days that exceed 10200 hits =np=365*0.0228=8.322

e)

Mean of distribution=μ=np= 8.3220  

and standard deviation σ=sqrt(np(1-p))= 2.8517  

For normal distribution z score =(X-μ)/σx  

P(more than 15 days has more than 10200 hits):

Probability =P(X>15)=P(Z>(15-8.322)/2.852)=P(Z>2.34)=1-P(Z<2.342)=1-0.9904=0.0096

One possible length of the third side of the given triangle is 15

From the question, we are to determine a possible length of the third side of the triangle

From one of the properties of a triangle, we know that

The sum of any two sides of a triangle is greater than the third side and the positive difference of any two sides of a triangle is lesser than the third side.

Thus,

8 + 17 is greater than the third side

25 is greater than the third side

and

17 - 8 is lesser than the third side

9 is lesser than the third side

If the third side of the triangle is x,
Then,

9 < x < 25

Hence, a possible value of x is 15

The linear equation representing this situation will be y = 4x, where y is the dependent variable and x is the independent variable.

As per the question statement, it is given that the perimeter of a square is equal to four times the length of its side and we are supposed to write the direct variation equation that represents this situation.

Also given that we have to use "y" and "x" which are dependent and independent variables respectively.

Perimeter = 4*side

So we conclude that perimeter is dependent on the independent value of side of the square.

Therefore, y = 4x would be the appropriate linear equation depicting the situation given.

The maximum profit will be $2,700.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The profit on a trick ski is $50 and the profit on a slalom ski is $30.

Let the number of Trick ski manufactured = x

And, Number of slalom ski manufactured = y

So, Maximize;

P = 50x + 30y

Subject to we get;

6x + 4y ≤ 108

And, x + y ≤ 24

And, xy ≤ 0

Now, We have to find set of feasible solutions graphically for the number of each type of ski that can be produced.

So, Linear equation in slope form;

6x + 4y = 108

y = -1.5x + 27

And, x + y = 24

y = - x + 24

So, By the graph we get;

The points,

(x , y) = (0, 24) , (6 , 18) (18, 0)

Hence, The maximum profit when 6 trick ski and 18 slalom ski manufactured.

maximum profit = 6 x 50 + 18 x 30 = 840

And, The maximum profit when 18 trick ski and 0 slalom ski manufactured.

maximum profit = 18 x 50 = 900

The maximum profit when 0 trick ski and 24 slalom ski manufactured.

maximum profit = 24 x 40 = 960

Thus, The maximum profit = 840 + 900 + 960

The image of the function after vertically stretched by a factor of 3 is f'(x) = 3|x + 1| - 3

From the question, the given parameters are:

f(x) = |x + 1| - 1

The transformation is given as

Vertical stretch by a factor of 3

This implies that we stretch the function f(x) by a factor of 3 across the origin

Mathematically, this transformation can be represented as

(x, y) = (x, 3y)

When represented as a function, we have

f'(x) = 3 * f(x)

Substitute the equation f(x) = |x + 1| - 1 in the equation f'(x) = 3 * f(x)

So, we have the following equation

f'(x) = 3 * (|x + 1| - 1)

Remove the bracket

So, we have

f'(x) = 3 * |x + 1| - 3 * 1

Evaluate the products

So, we have

f'(x) = 3|x + 1| - 3

Hence, the equation of f'(x) is f'(x) = 3|x + 1| - 3
