Using the mass ratio, the spacecraft's velocity was determined to be 7.7025 km/s.

Here, c = 2.7 km/s, t = 30s, R = 20

On substituting the values of 'R', 't', 'v', we get:

v = -0.0098 ( 30) + 2.7 ( ln (20))

=> v = - 0.294 + 2.7 (2.995)

=> v = 7.7025 km/s

We need to use the concept of lines and slopes to solve the problem.The equation of the line that passes through (5,-2) and is perpendicular to y=[tex]\frac{5}{3} x-3[/tex] is [tex]y=\frac{-3}{5} x+\frac{19}{5}[/tex].

We will be using the concept of lines and slopes to solve the question. When two lines are parallel their slopes are equal and when two lines are perpendicular the product of their slopes equal to -1.

Here we know that the line passes through a point (5,-2) and is perpendicular to another line,we need to find out the slope of the line first.

Let slope of given line be m1 and slope of the line that we need to find out be m2.

[tex]y=\frac{5}{3} x-3[/tex]

slope is the coefficient of x, thus m1=[tex]\frac{5}{3}[/tex]

we know that m1xm2=-1

[tex]\frac{5}{3}[/tex]×m2=-1⇒m2=[tex]\frac{-3}{5}[/tex]

The formula that we need to find the equation of a line is

The composite functions of the model taking the 20 % discount and then the 15 % discount is (D ◦ E)(x) = 0.68x.

In mathematics, function composition is an operation in which two functions, f and g, generate a new function, h, in such a way that h(x) = g(f(x)). This means that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

Define fog, the composition of f and g, as (fog)(x) = f(g(x)) for functions f and g. g should be applied to x. If fog(x) = x and gof (x) = x for all x values in the domain of f and g, then they are inverse functions.

In math, the domain (the x-values) of one function becomes the range (the y-value answers) of the next function. Composition notation is as follows: (f o g)(x) = f(g(x)) and exists read “f composed with g of x” or “f of g of x”.

Let D(x) = cost after applying the 15% discount,

E(x) = cost after applying the 20% employee discount, and x = cost of item(s).

Then D(x) = 0.80x and E(x) = 0.85x.

(D ◦ E)(x) = 0.68x.

If I were George Washington, I would have put two very different people to advise me because I would have a broader vision of government affairs.

George Washington (1732-1799) was an American politician and military man who stands out for being one of the most influential people in history and for having served as the first president of the United States between 1789 and 1797. He is considered the most important father of the Nation of the United States.

In 1789 he was unanimously elected by the other founding fathers as the first president of the United States. During his rule he tried to create a nation capable of maintaining peace with its neighboring countries, so he proclaimed neutrality to avoid any involvement in foreign conflicts.

For George Washington it was a challenge to occupy the position of the first president of the United States because he was going to lead a country that was just being formed. Due to the above, it was of vital importance to include all forms of thought and all visions in its government plan and way of governing.

Therefore, when assuming office as president of the United States, it would be of great importance to have advisers who would help him see from the point of view of other people so that his decisions would take into account the interests of all citizens to avoid uprisings and divisions.

Define the variables:

Let the two numbers be x and y, where x > y.

Given information:

Create two equations from the given information and defined variables:

[tex]\begin{cases}x = 4y + 1\\x + y = 106\end{cases}[/tex]

Substitute Equation 1 into Equation 2 and solve for y:

[tex]\implies (4y+1)+y=106[/tex]

[tex]\implies 4y+1+y=106[/tex]

[tex]\implies 5y+1=106[/tex]

[tex]\implies 5y+1-1=106-1[/tex]

[tex]\implies 5y=105[/tex]

[tex]\implies \dfrac{5y}{5}=\dfrac{105}{5}[/tex]

[tex]\implies y=21[/tex]

Substitute the found value of y into the second equation and solve for x:

The domain of f(x) to be [0,∞).

If the domain R, f(x) is not one to one, so its inverse exists not a function.

If we restrict the domain of f(x) then we can define an inverse function.

An inverse function, even comprehended as an anti function, is a function that can be reversed into another function. Simply put, if any function " f " takes x to y, then its inverse will take y to x. The inverse function is denoted by f-1 or F-1 if the function exists denoted by ' f ' or ' F '.

In order to have an inverse function, a function must be one to one.

In the case of f(x) = x⁴ we find that f(1) = f(−1) =1.

If f(x) exists not one to one on its implicit domain R.

If we restrict the domain of f(x) to [ 0, ∞) then it does contain an inverse function, then [tex]f^{-1}(y)=\sqrt[4]{y }[/tex]

Let the given function be y = f(x) = x⁴

Taking the square root of both ends, then we get

± √y = x²

Let the real values be x, then

We require the left hand side to be non-negative, so assume the non-negative square root.

Take the square root of both sides of the equation then

±[tex]\sqrt[]{\sqrt{y} }[/tex] = x

⇒ x = ± [tex]\sqrt{\sqrt{y} }[/tex] = ± [tex]\sqrt[4]{y}[/tex]

It  does not give us a unique value of x in terms of y.

So the inverse function exists not defined, then x ≥ 0,  

i.e., restrict the domain of f(x) to be [0,∞).

If the domain R, f(x) exists not one to one, so its inverse exists not a function.

The length of AB is 4.47 units, the length of CD is 2.83 units and the length of EF is 5 units.

We are given different right angled triangles.

We need to find AB, CD and EF

We will do this by using the Pythagoras theorem.

Pythagoras theorem states that:

Hypotenuse² = Base² + Perpendicular²

For AB,

Hypotenuse = AB

Base = 2 units

Perpendicular = 4 units

So, we get that:

AB² = 2² + 4²

AB² = 4 + 16

AB² = 20

AB = √ 20

AB = 2√5 units

AB = 4.47 units.

For CD:

Hypotenuse = CD

Base = 2 units

Perpendicular = 2 units

So, we get that:

CD² = 2² + 2²

CD² = 4 + 4

CD² = 8

CD = √ 8

CD = 2√2

CD = 2.83 units

For EF:

Hypotenuse = EF

Base = 4 units

Perpendicular = 3 units

So, we get that:

EF² = 4² + 3²

EF² = 16 + 9

EF² = 25

EF = 5 units.

Therefore, we get that, the length of AB is 4.47 units, the length of CD is 2.83 units and the length of EF is 5 units.

If two water tanks are 50 inches tall and tank a is empty and for each minute the water increases by 3.7 inches and tank b is draining and the water decreases by 1.9 inches each minute, then the minutes after which the height of the water in each tank is the same is equal to 9.

The time in minutes after which the height of the water in each tank is the same can be determined by using a linear equation.

The equation for this problem can be given as,

0 + 3.7(x) = 50 - 1.9(x)

Here x is equal to minutes. To find the minutes after which the water level will be the same can be determined by calculating the value of x in this linear equation.

3.7(x) + 1.9(x) - 50 = 0

5.6(x) = 50

x = 50 / 5.6

x = 8.92 ≈ 9

Vertical Angle Theorem: two angles that are formed by two intersecting lines and are opposite each other are equal

The value of x is 23 because Angle FGI and Angle HGC are vertically opposite angles, the answer is 23.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

The triangle and two parallel lines are shown in the picture.

As we know, from the definition of the vertically opposite angle, two lines intersect each other at the intersecting point.

Angle FGI = Angle HGC = 14 degrees

4x = 78 + Angle HGC

4x = 78 + 14

4x = 92

x = 92/4

x = 23
