The domain of the function x - 3 + 5 is  x ∈ R(real number)

A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain.

The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range.

The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A->B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output.

The function is

f(x) = x - 3 + 5 = x + 2

for all value of x ∈ real number the function is define

So , the domain of the function x - 3 + 5 is  x ∈ R(real number)

Question 2: No Solution

Question 4: (2,-3)

Step-by-step explanation:

Question 2: {x-y=7} {x-y=-4}

Question 4: {5x+2y=4} {9x+2y=12}

There is two ways of solving this;

Elimination method and Substitution method.

I will be using the Substitution method for Question 2 and Elimination method for Question 4.

Substitution method is basically substituting in the equation like this;

Question 2:

x - y = 7 and x - y = -4

x - y = 7 into x = 7 + y

Substitute:

7 + y - y = - 4

7 = - 4

7 ≠ - 4

Therefore, there no solution to this equations.

Question 2: No Solution

Question 4:

Elimination Method is basically eliminates one of the variables, so we can solve a more simplified equation.

5x + 2y = 4 and 9x + 2y =12

5x + 2y = 4

-(9x + 2y = 12) - Multiply this equation by -1.

Now we have;

5x + 2y = 4

-9x -2y = -12

-4x = -8

x = 2

We can substitute x  to find y.

5(2) + 2y = 4

10 + 2y = 4

2y = -6    

y = -3

Question 4 Solution: (2,-3)

To find the coordinates of the point that partitions the directed line segment from ( − 5 , 4 ) to ( 1 , 8 ) into a ratio of 3 to 1, we can use the following formula:

(x,y) = (1- t) * (x1, y1) + t * (x2, y2)

Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the directed line segment, t is a value between 0 and 1 that represents the ratio of the partition, and (x, y) are the coordinates of the point that partitions the segment.

In this case, we want the ratio of the partition to be 3 to 1, so t = 3 / (3 + 1) = 3/4

So we can substitute the values into the formula:

(x,y) = (1- 3/4) * (-5, 4) + (3/4) * (1, 8)

(x,y) = (-5/4, 4/4) + (3/4, 6/4)

(x,y) = (-5/4+3/4, 4/4+6/4)

(x,y) = (-2/4, 10/4)

(x,y) = (-0.5, 2.5)

So the point that partitions the directed line segment from ( − 5 , 4 ) to ( 1 , 8 ) into a ratio of 3 to 1 has coordinates (-0.5, 2.5)

Roscoe is faster.

Speed is a scalar quantity that refers to "how fast an object is moving."

Given that, Emmy and Roscoe both run every day. Yesterday Emmy ran 8 mile in 2 hours. Roscoe ran 6 ½ miles in 1 ½ hours.

Speed = distance / time

Emily's Speed = 8 / 2 = 4 mph

Roscoe's speed = 6 ½ / 1 ½ = 6.5 / 1.5 = 4.33 mph

Since, Roscoe's speed is greater than Emily's speed.

Part a: Area of habitat - Area of field = Area of mowed portion.

Part b: Area of mowed portion: 4x(b - x)

For the stated question:

Part a:

The complete area is given as: Area of habitat.

The area kept for birds: Area of mowed portion

Central unmowed portion: area of field

Thus,

Area of habitat - Area of field = Area of mowed portion

Part b: Area of mowed portion: 4x(b - x)

Proof:

b² - (b - 2x)² = [b - (b - 2x)] [b + (b - 2x)]

                    =  [b - b + 2x] [b + b - 2x]

                    = (2x)(2b - 2x)

                    = 4x(b - x)

Thus, the Area of mowed portion: 4x(b - x).

After using Pythagorean theorem the rectangular floor is 4m long.

What is Pythagorean theorem ?

 A right angled triangle's missing length can be discovered using Pythagoras' Theorem.

The triangle has three sides: the adjacent, which doesn't touch the hypotenuse, the opposite, which is always the longest, and the hypotenuse (which is between the opposite and the hypotenuse).

Here in the given rectangular floor,

Width = 3m and Altitude which is hypotenuse = 5 m.

Now using Pythagorean theorem,

=> [tex]length^2+width^2=hypotenuse^2[/tex]

=> [tex]length^2+3^2=5^2[/tex]

=> [tex]length^2=5^2-3^2[/tex]

=> [tex]length^2=25-9=16=4^2[/tex]

The rate of B is  -0.003072 M/s.

The average rate of change is a measure of how much a quantity changes over a certain period of time. In this case, we are looking at the concentration of B, and we want to know how much it changes over the time interval from 0 to 332 seconds. To calculate this, we first need to determine the initial and final concentrations of B at these two points in time.

From the given data, we know that

Once we have these values, we can calculate the change in concentration of B by subtracting the initial concentration from the final concentration: 0.160 M - 0.670 M = -0.510 M. This tells us that the concentration of B decreases by 0.510 M over the time interval from 0 to 332 seconds.

Next, we need to divide this change in concentration by the length of the time interval to get the average rate of change. The length of the time interval is the difference between the final and initial time: 332 s - 0 s = 332 s. So, the average rate of change of B is (-0.510 M) / (332 s) = -0.001536 M/s. This tells us that the concentration of B decreases by 0.001536 M per second on average over the given time interval.

As we know that the reaction is of form A -> 2B, the rate of formation of B is equal to twice the rate of A.

So, Rate of B = 2* Rate of A =  2*(-0.001536) = -0.003072 M/s

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: Distance of stake to the pole=14 feet and Distance from the pole to the tower as =25 ft. And height of the pole=10 feet.

Now let the angle that the guy wire makes with the stake is θ

Then we have Tanθ= 10/14

                                 =5/7

Again we also have Tan θ= height of the tower /base of the tower

Thus h/39=5/7 ( where h is the height of the tower).

    or, h=27.85

 Therefore using pythagoraes theorem we get the length of the wire as
