As every occupied makes the hotel collect 125, the dollars the hotel generates are:

It means that the correct answer is the last option.

the domain is the interval or set of all valid values for x (the input variable).

the range is the interval or set of all valid values for y or f(x) (the function result variable).

the functional result values for the first piece :

x - 4 for 0 <= x < 2

for x = 0 we get y = -4

for x = 2 we get y = -2

the range for this piece is [‐4, -2).

we use the round bracket to indicate -2 itself is not included, as we have x < 2 (and not x <= 2).

the functional result values for the second piece :

x² - 3x + 4 for 2 <= x < 4

for x = 2 we get 4-6+4 = 2

for x = 4 we get 16-12+4 = 8

the range for this piece is [2, 8)

again, because of x < 4 we use the ")" for 8 (not included).

the functional result values for the third piece :

5 for 4 <= x < 7

the range is simply [5) = [5] because the set contains only one element.

and 5 is already contained in the range of the second piece.

so, the range is just the combination of the ranges of the first 2 pieces :

[-4, -2) U [2, 8)

No,  the form that Maria expanded is not correct.

What does it mean to "extend and simplify"?

We must multiply out the brackets in order to expand and simplify an expression, and we must then collect like words in order to simplify the resulting expression. We take out brackets by expanding them, often known as multiplying out.

Given:

(x+3)²

= x² + 2 . 3 . x + 3²

= x² + 6x + 9

Therefore the correct expansion is x² + 6x + 9.

Through the diagram, we can see that if we cut the image to get the cross section perpendicular to its base, we would get the same shape as the image, which is a pentagon.

Answer:

slope = 5/2

Step-by-step explanation:

Locations of points: (-4 , -4) and (-2 , 1)

slope = rise / run

between two plotted points this means that:

slope = change in y / change in x

slope = (1 - (-4)) / (-2 - (-4))

slope = 5/2

The solution to the given expression is 10√5 - 4√10 which is the correct answer would be an option (C)

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

The given expression as:

⇒ √5(10 - 4√2)

Open the parentheses and apply the distributive property of multiplication to get,

⇒ 10√5 - 4√5√2

⇒ 10√5 - 4√(5 × 2)

⇒ 10√5 - 4√10

Therefore, the solution to the given expression is 10√5 - 4√10.

What is Integer ?

An  integer is a whole number from the set of -ve , non-negative , +ve and 0 numbers.

Let's see how both the option is  correct

we know, integers are 0,1, 2, 3, .... or -1, -2 , -3 ......

Means the number which is not in fraction or decimal value or root.

so, by seeing option(a) we can say it's an integer

but in option(b) it's the root so how it is integer

The answer is simple it's perfect square of 12 so √144 = 12 so that means it have the value which is not in fraction. By that we can say that option(b) is also an integer

Now, in option(c) and (d) they are not the perfect square and their root results in decimal values. so we cannot tell them as an integer value.

Hence, the answer is either Option (a) or option(b) or both the options.

The limit of xlnx when x is tending towards zero is zero.

What is limit in mathematics?

In mathematics, a limit is the value that a function (or sequence) approaches as the input (or index) approaches a particular value. Without limits, it is impossible to perform calculus or mathematical analysis; limits are also necessary to compute continuity, derivatives, and integrals.

Given limit is:

[tex]\lim_{x \to 0} x lnX[/tex]

Considering f = x, and g = ln x

The limit of f and g are both zero or both ±∞, and the limit f′/g′ exists, then the limit f/g equals it.

The wrong in the expression x lnx is we are individually defining f and g doesn't meet the hypothesis. so, we write it as

[tex]\frac{lnx}{1/x}[/tex]

We now use L' Hospital rule with f(x) = lnx, g(x) = 1/x as

The limits

[tex]\lim_{x \to 0^+} lnx= - \infty[/tex], and

[tex]\lim_{x \to 0^+} \frac{1}{x}[/tex]

The limits  [tex]\lim_{x \to 0^+} \frac{f'(x)}{g'(x)}[/tex] exists as:

[tex]\lim_{x \to 0^+} \frac{1/x}{-1/x^2} = \lim_{x \to 0^+} -x = 0[/tex]

Hence the answer is 0.

Weight of one apple is 8 ounces.

We have to calculate the weight of one apple. For that firstly, we have to calculate the weight of one apple in pounds because we have been given the weight of 96 apples in pounds. After that, we will convert it into ounces and we know that one pound is equal to 16 ounces.

A bushel has 96 apples.

We have been given weight of 1 bushel which is 48 pounds.

Weight of 96 apples = 48 pounds

We have to calculate weight of one apple.

Weight of one apple = 48/96 = 1/2 pound

1 pound = 16 ounces.

Now, we have to convert pounds into ounces

Weight of one apple = 1/2 * 16 ounces

= 8 ounces

Hence, the answer is 8 ounces.

Answer to question (b) that is if [tex]A^{T}[/tex] y = c has a solution and Ax = 0 then x is perpendicular to c.

a) As Ax = b has a solution for x this means b lies in the column space of A. We also know that [tex]A^{T}[/tex] y = 0. This means y lies in the orthogonal complement of the column space of A or in the left null space of A. Therefore y is perpendicular to b

b) We see [tex]A^{T}[/tex] y = c has a solution. This tells us that c lies in the row space of A and also from the given Ax = 0 we can deduce that x lies in the null space of A or the orthogonal complement of row space of A. Therefore evidently  x will be perpendicular to c

Answer: the answer is 441

Step-by-step explanation: 75% of 588 is 441

There were 120150 federally insured bank in the year 1987. The slope of the graph of B is -326.6.

The provided function B(x) states the number of federally insured banks from 1982-2004.

The function B(x) is,

B(x) = -326.6t + 13783

Here t is representing the year,

This function is a linear function corresponding to an equation of line,

If according to the situation,

t = 0, signifies the year 1982,

Then the year 1983 should be represented by t = 1.

On continuing the pattern the year 1987 should be represented by t = 5.

So, the number of federally insured banks in year 1987 can be found by putting t = 5 in B(x),

B(5) = -326.6(5) + 13783

B(5) = 12150.

The number of banks federally insured in year 1987 is 12150.

The function is B(x)= -326.6t + 1783,

This is representing the point-slope form of the line,

y = mx + c,

On comparing the provided function with the standard equation we can see,

Slope m = -326.6

So the slope of the function is -326.6.

M is the midpoint of the line segment FG.

Being the midpoint means that M divides the line in two equal halves so you know that the distance between F and M is equal to the distance between M and G, symbolically:

FM=MG

And of you add them you'll be able to calculate the length of the whole line FG

34.

Given the expressions

FM= 5y+13

MG=5-3y

We know that FM=MG, so the first step is to replace this equivalency with the given expressions. This way you'll determine an equation with one unknown y.

Once you have the equation you can clear the value of y:

Pass all terms with the unknown to one side of the equation and all others to the other side:
