The solutions for the system of equations is the point (2, 2).

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Given are two linear equations,

y = -x + 4 and

y = 2x - 2

First graph the lines.

For that, find two points on each equation and join them.

x = 0, then y = 4

y = 0, then x = 4

We have two points (0, 4) and (4, 0). Join these points to form the line.

x = 0, then y = -2

y = 0, then x = 1

We have two points (0, -2) and (1, 0). Join these points to form the line.

We have two equations, which are equal to each other.

-x + 4 = 2x - 2

-x - 2x = -2 - 4

-3x = -6

x = 2

y = -2 + 4 = 2

So the solution of the system of equations is the intersecting point of the two lines which is (2, 2).

Hence the solution of the system of equations is (2, 2).

The double integral. ∫∫R 2x/1 + xy dA, R = [0, 2] × [0, 1] is: 2*(1/2ln(3) - 1/2ln(1))

To calculate the double integral ∫∫R 2x/1 + xy dA, we need to integrate with respect to x and y over the region R = [0, 2] × [0, 1].

We can solve this by using the order of integration.

First we need to fix the limits of integration with respect to y and then integrate with respect to x.

∫∫R 2x/1 + xy dA = ∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy

∫(0 to 1) (∫(0 to 2) 2x/(1+xy) dx) dy = ∫(0 to 1) ( 2*ln(1+xy)|x=0 to 2) dy

∫(0 to 1) ( 2ln(1+2y) - 2ln(1+0) ) dy

= 2*∫(0 to 1) ln(1+2y) dy

= 2*[y*ln(1+2y) - ∫(0 to 1) ln(1+2y) dy] |y = 0 to 1

= 2*[yln(1+2y) - (1/2 ln(3) - 1/2* ln(1))] |y = 0 to 1

= 2*(1ln(3) - 0ln(1) - 1/2* ln(3) + 1/2* ln(1))

= 2*(1/2ln(3) - 1/2ln(1))

A room classified as a group a-2 occupancy has dimensions of 60 feet by 80 feet and is in a sprinklered building. the minimum required separation distance from the nearest exit door is  r is 50 feet

This is determined by the occupancy type of the room, which is classified as a Group A-2 occupancy. According to the International Building Code, Group A-2 occupancies are those that involve assembly uses with an occupant load of 50 or more and with fixed seating. Therefore, the minimum required separation distance from the nearest exit door is 50 feet.  

To calculate this, I referred to the International Building Code (IBC) Chapter 10, which outlines the requirements for means of egress. Section 1020.1 of the IBC states that the required separation distance between an exit door and the nearest obstruction must be at least half the length of the maximum overall diagonal dimension of the room. Since the room has dimensions of 60 feet by 80 feet, the maximum overall diagonal dimension is 100 feet.

Therefore, half of this distance is 50 feet, which is the minimum required separation distance from the nearest exit door.   In addition, the IBC also requires that Group A-2 occupancies be sprinkled, which the room in question is. This means that there may be additional requirements for separation distances for the egress system depending on the specific type of sprinkler system being used.

a room classified as a group a-2 occupancy has dimensions of 60 feet by 80 feet and is in a sprinklered building. what is the minimum required separation distance from the nearest exit door?

Answer:

  2.4×10⁶

  2,400,000 in the US

Step-by-step explanation:

You want the value of the expression x²/y rounded to an appropriate precision when x=3.8×10⁵ and y=5.9×10⁴.

The attached calculator display shows the result to 2 significant figures, the appropriate for computation using values that have 2 significant figures.

  x²/y ≈ 2.4×10⁶

In the US, "standard form" would be the usual form in which numbers are written:

  x²/y ≈ 2,400,000

__

Additional comment

If you're working this out with pencil and paper, the value you want to compute is ...

  (3.8×10⁵)²/(5.9×10⁴) = (3.8²/5.9)×10¹⁰⁻⁴ = (144.4/59)×10⁶ ≈ 2.4×10⁶

<95141404393>

We can rewrite the expressions by using exponent properties:

(225a¹⁰)/(5a²)² =  9a⁶

(x⁵/3)³*81x⁴ = 3x¹⁹

Here we need to use some exponent properties, these are:

(xᵃ)ᵇ = xᵃᵇ

xᵃ/xᵇ = xᵃ⁻ᵇ

Here we have the expression:

(225a¹⁰)/(5a²)²

We can rewrite the denominator as:

(5a²)² = 25a⁴

We can rewrite it as:

(225a¹⁰)/ 25a⁴ = (225/25)*(a¹⁰/a⁴) = 9*a¹⁰⁻⁴ = 9a⁶

The other expression is:

(x⁵/3)³*81x⁴

(x¹⁵/27)*81x⁴ = (x¹⁵*x⁴)*(81/27) = 3*x¹⁵⁺⁴ = 3*x¹⁹

The limit exists, where limx→+∞ ex=+∞  and  limx→+∞ arctanx=π\2

This problem can be solved by dividing it into smaller parts.

Let f(x)=ex and g(x)=arctan(x)

The range of the function arctan(ex) is equal to the intersection of the ranges of f(x) and g(x).

Since the range of f(x) is [0,∞] and the range of g(x) is [−π/2,π/2], the intersection is [0,∞] ∩ [−π/2,π/2] or [0,π/2]

but the limit as x approaches infinity or limx→∞.

Since the highest number in the possible range is π/2, that is the limit as x approaches infinity.

if x is approaching negative infinity or limx→−∞, the answer would be the lowest value in the function's range. Therefore, it would be 0

A triangle is a right angle triangle if and only if the Pythagorean theorem holds true for the sides of the triangle. The Pythagorean theorem states that in a right angle triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we can call the side opposite the right angle the hypotenuse, and the other two sides the legs. According to the information given, the hypotenuse is AC, and the legs are AB and BC.

So, we can use the Pythagorean theorem to check if this triangle is a right angle triangle:

AC^2 = AB^2 + BC^2

26^2 = 10^2 + 25^2

676 = 100 + 625

676 = 725

This equation does not hold true, so the triangle is not a right angle triangle.

The number of such paths from (0,0) to (85,65) is C(150, 85).

What is co-ordinate ?

In mathematics, a coordinate is a pair of numerical values that represent a specific location on a two-dimensional surface, such as a graph, a map, or an image. The two values are usually referred to as the x-coordinate and the y-coordinate.

A path from (0,0) to (85,65) on the integer grid that starts at (0,0) and increments one coordinate by 1 and leaves the other unchanged at each step is equivalent to a sequence of 85 "right" steps and 65 "up" steps. The number of ways to arrange these steps is given by the binomial coefficient C(85+65, 85), which is the number of ways to choose 85 items (the "right" steps) from a set of 150 items (85 "right" and 65 "up" steps) without replacement and where order matters.

The general formula for the binomial coefficient is C(n, k) = n! / (k!(n-k)!), where n! is the factorial of n, i.e., the product of all integers from 1 to n, and k! is the factorial of k. Using this formula, we have:

C(150, 85) = 150! / (85!(150-85)!) = (150149148*...6665) / (858483*...1) = (150149148...6665) / (85!)
