What are Exponents and Power?

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.

Given:

2ab (∛192ab²) -5(∛81 [tex]a^4b^5[/tex])

Now, factorizing the terms as

192ab² = 2 x 2 x 2 x 2 x 2 x 2 x 3 x a x b x b

81 [tex]a^4b^5[/tex] = 3 x 3 x 3 x 3 x a x a x a x a x b x b x b x b x b

So, 2ab (∛192ab²) -5(∛81 [tex]a^4b^5[/tex])

= 2ab (∛2 x 2 x 2 x 2 x 2 x 2 x 3 x a x b x b) -5(∛3 x 3 x 3 x 3 x a x a x a x

                                                                                    a x b x b x b x b x b)

= 2ab ( 2 x 2 ∛ 3 x a x b x b) -5( 3 x a x b ∛3 x a x b x b )    

= 8ab ∛ 3ab² - 15ab∛ 3ab²                            

= -7ab ∛ 3ab²

Hence, the simplified expression is ab∛ 3ab².

The required roster form of the given sets are C ∩ (B’ ∪ A) = {p, q}.

What is the roster form of a set?

The roster form of a set is defined as a set that can be represented mathematically in a precise way using a roster notation. In a roster notation, if the set has more than one element, a comma is used to denote the separation between every pair of elements.

The given sets are defined as follows:

U = {f, g, h, p, q, r, x, y, z}

A = {f, g, p, q}

B = {g, h, q, x, y}

C = {p, q, x, y, z}

The complement of set B is the set of all elements in the universal set U that are not in set B.

U = {f, g, h, p, q, r, x, y, z}

B = {g, h, q, x, y}

B’ = {f, p, r, z}

The union of set B' and A is the set of all elements that are in set B' or in set A.

A = {f, g, p, q}

B’ = {f, p, r, z}

B’ ∪ A = {f, g, p, q, r, z}

The intersection of set C and (B’ ∪ A) is the set of all elements that are in both set C and set (B’ ∪ A).

C = {p, q, x, y, z}

B’ ∪ A = {f, g, p, q, r, z}

C ∩ (B’ ∪ A) = {p, q}

So, C ∩ (B’ ∪ A) = {p, q}

Question 5 Piecewise graphs. Graph each of the given functions. Be sure to clearly indicate possible points that may be significant. 2 (a) f(x) = x^2 +1

Answers

The function f(x) = x^2 + 1 can be graphed using the coordinates (x, y) where x is the x-coordinate, and y is the y-coordinate.

This function can be written as y = x^2 + 1. Using this equation, we can plot the graph of the function. To plot the graph, we need to plot points on the x-axis and y-axis. The x-axis is the horizontal line and the y-axis is the vertical line.

For example, let us take a point x = 0. Substituting x = 0 in the equation f(x) = x^2 + 1, we get y = 0^2 + 1, which is equal to 1. So, we can plot the point (0,1) on the graph. Similarly, we can plot the point (1,2), (2,5), (3,10), (4,17), (5,26), and so on.

By plotting all these points, we can get the graph of the function f(x) = x^2 + 1. This graph is a parabola with vertex at (0,1). It is an increasing function, which means that as the value of x increases, the value of y also increases. The graph is also symmetric about the y-axis.

Answers

The angle measures for this problem are given as follows:

m < AFB = 60º.m < BFE = 60º.

How to obtain the angle measures?

The sum of the measures of the internal angles of a polygon with n sides is given as follows:

S(n) = 180 x (n - 2).

Hence, for an hexagon, with six sides, the sum is given as follows:

S(6) = 180 x (6 - 2)

S(6) = 720º.

A regular hexagon has all angle measures equal, hence the measure of each angle is given as follows:

720/6 = 120º.

The segment FB is a bisection of the angle F of the hexagon, dividing it into two equal angles, hence the angle measures are given as follows:

A rock is thrown upward with a velocity of 18 meters per second from the top of a 36 meter high cliff, and it misses the cliff on the way back down. when will the rock be 4 meters from the water, below? round your answer to two decimal places.

Answers

The time that is taken to fall is  3.1 s.

What is the time required?

In this case, we have been told that A rock is thrown upward with a velocity of 18 meters per second from the top of a 36 meter high cliff, and it misses the cliff on the way back down.

We have to know that the maximum height that the rock has attained by the use of the formula;

v^2 = u^2 - 2gh

v = final velocity

u = initial velocity

g = acceleration

h= distance

v = 0 m/s at the maximum height

h = u^2/2g

h = (18)^2/2 * 9.8

h = 324/19.6

h = 16.5 m

The height from the cliff upwards is; 16.5 m + 36 m = 52.5 m

The distance that is covered when falling is;  52.5 m - 4 m = 48.5 m

If it is falling then it is dropped from a height and u = 0 m/s

h = 1/2gt^2

48.5 = 0.5 * 9.8 * t^2

t = √48.5/0.5 * 9.8

Here proof i.e. ∠1=∠3 is also given in the image for the given geometric shape.

What are geometric shapes?

In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.

Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.

In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc.  In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.

Now

To prove   ∠1=∠3

Here as given ∠1+∠4=180°

and also ∠2+∠3=180°    (supplementary angles)

therefore,

∠1+∠4=∠2+∠3

What is exponential expressions?

Simply put, exponential expressions are a condensed approach to express powers. The base's frequency of use as a factor is indicated by the exponent.

f(x) = ax, where x is the input variable and is expressed as an exponent, is the formula for an exponential function.

In addition to being dependent on the exponential function, the exponential curve also depends on the value of x. Whenever a>0 and a1 are not equal.

Example :

3(5x + 3).(27)x as 3f(x) : 3.5x(27.3,x(x)f) +3 .3 (27 .3,x(x)f)

Steps

3(5x+3)(27x , 3f(x))

= 3(5x + 3)(27.3,x(x)f)

Apply the distributive law :

a(b + c) = ab + ac

a = 3(27x,3f(x)), b=5x,c = 3

=3(27x,3f(x)). 5x + 3(27x,3f(x)).3

Answers

The missing coordinate of P, using the fact that P lies on the unit circle in the given quadrant is √(2/7) or √(2/7)

The unit circle is a circle with a radius of 1 centered at the origin (0,0) on a coordinate plane. If a point P lies on the unit circle, then the distance from the origin to P is 1.

We can use the distance formula to find out the missing coordinate of P.

The distance formula:   [tex]d = \sqrt((x2 - x1)^2 + (y2 - y1)^2)[/tex]

where (x1, y1) is origin and (x2, y2) is the point P.

Given in the problem that P is in Quadrant IV, then the (x, y)-coordinate is negative.

So we can use the given information and the distance formula to find out the missing coordinate.

[tex]d = \sqrt((x2 - 0)^2 + (y2 - 0)^2) = 1[/tex]

x2 = -5/7, y2 = -5/7

[tex]d = \sqrt((-5/7 - 0)^2 + (-5/7 - 0)^2) = \sqrt((-5/7)^2 + (-5/7)^2) = \sqrt(25/49 + 25/49) = \sqrt(50/49) = \sqrt(2/7) = 1[/tex]

The rate of change In gallons of gas per year from 1995 to 1997 is: C. Δg/Δt = 4 gal/year.

How to calculate the rate of change?

In Geometry, the rate of change of the data in this table can be calculated by using this mathematical equation;

Rate of change (slope), m = (Change in y-axis, Δg)/(Change in x-axis, Δt)

Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)

From the information provided in the graph above, we can logically deduce the following data points located on the line:

Points on the x-coordinate = (1995, 1997).Points on the y-coordinate = (530, 538).

Substituting the given data points into the rate of change formula, we have the following;

Rate of change (slope), Δg/Δt = (y₂ - y₁)/(x₂ - x₁)

Rate of change (slope), Δg/Δt = (538 - 530)/(1997 - 1995)

Find how the spaceship velocity modulus increased in the process of braking.

Answers

The spaceship's velocity modulus increased due to the firing of the brake rocket in order to transfer the spacecraft into a circular orbit of the Moon satellite.

When approaching the Moon, a spacecraft follows a parabolic trajectory which is almost tangent to the Moon's surface. At the moment of maximum approach, the brake rocket is fired for a short time interval. This causes a decrease in the spacecraft's velocity and an increase in its centripetal force. This, in turn, causes the spacecraft to move away from the Moon and into a circular orbit of a Moon satellite. The increased centripetal force causes the spacecraft to accelerate, and thus its velocity modulus increases. The magnitude of this increase in velocity modulus depends on the duration and power of the brake rocket. In conclusion, the velocity modulus of the spacecraft increases due to the firing of the brake rocket.

The change in y between x = 5 and x = 9 is 2572.

What is a function?

An assignment of a Y element to every X element constitutes a function from X to Y. Both the set X and the set Y are referred to as the function's domain and codomain, respectively.

Here, the function is given as y(x) = 4x ^ 3 + 3x ^ 2 - 3x.

we'll find the value of given function i.e. y when x = 5 and 9.

when x = 5,   y(5) = 4(5) ^ 3 + 3(5) ^ 2 - 3(5)

                            = 4(125) + 3(25) - 15

                            = 500 + 75 - 15

                            = 560.

when x = 9,   y(9) = 4(9) ^ 3 + 3(9) ^ 2 - 3(9)

                            = 4(729) + 3(81) - 27

                            = 2916 + 243 - 27

Enter the correct answer in the box.

_______cm^2

Answers

The amount of tin was used to make the can of cylindrical can is 478 cm²

What is an equation?

An equation is an expression that shows the relationship between numbers and variables.

Area is the amount of space occupied by a figure. Area is usually calculated for a two dimensional shape while volume is calculated for a three dimensional shape.

The surface area of cylindrical can = 2π(radius * height + radius²)

From the image:

radius = 9 cm/2 = 4.5 cm, height = 12.4 cm

Hence, substituting:

The surface area of cylindrical can = 2(3.14)(4.5 * 12.4 + 4.5²) = 478 cm²

The surface area of cylindrical can is 478 cm²

In a statistics course a linear regression equation was computed to predict the final exam score from the score
on the first test. The equation of the least-squares regression line was y=10+0.9x where y represents
the predicted final exam score and x is the score on the first exam.

Answers

As per the given equation of the least squares regression line y=10+0.9x the score of Carla's final exam is 95.5.

As given in the question,

Given equation of the least squares regression line is :

y = 10 + 0.9x

Where 'y' shows the predicted final exam score

And 'x' represents the score of the first exam.

Carla's first exam score is equal to 95

Then predicted value 'y' of the Carla's final exam score is given by :

y = 10 + ( 0.9 ) × 95

⇒ y = 10 + 85.5

⇒ y = 95.5

Therefore, the predicted final score of Carla's as per the given least squares regression line is equal to 95.5.

find the range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2. (source: hmmt)

Answers

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2.

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2 can be calculated using the following formula:

Range = Maximum Value - Minimum Value

The expression inside the parentheses can be simplified to 3cos2a cos4a + 3sin2a sin4a and the expression inside the exponential can be simplified to tan2a (1 / cos2a - sin2a). This gives us the expression

Range = 3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)

To calculate the maximum and minimum values, we can use derivatives to find the critical points of the expression. Taking the first derivative with respect to a, we get

d/da (3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)) = 0

Solving this equation gives us the critical points of a = ±7t/6. Using these values, we can calculate the maximum and minimum values of the expression.

Maximum Value = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6)

Minimum Value = 3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6)

Finally, using the formula for the range, we can calculate the range of the expression to be

Range = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6) - (3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6))

This expression gives us the range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2.

Two angles are supplementary if the sun of their measures is 180 degrees find two supplementary angles such that one is 150 degrees more than 1/5 of the others

Answers

The two supplementary angles are 155 and 25.

What are supplementary angles?

Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given;

Two angles are supplementary

One is 150 degrees more than 1/5 of the others

Let one angle be x

Then the other angle will be x/5+150

Now,

x+ x/5+150=180

6x/5+150=180

6x/5=180-150

6x/5=30

x=150/6

x=25

Other angle= x/5+150=25/5+150

=155

Therefore, the angles will be 155 and 25.

Answers

Based on the table, a statement which is true include the following: C. The table shows a linear relationship, but not a proportional relationship.

What is a proportional relationship?

In Mathematics, a proportional relationship is a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:

y = kx

Where:

y represents the distance.x represents the time.k is the constant of proportionality.

Next, we would determine the constant of proportionality (k) for the data points on this graph as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 6/2 ≠ 11/4 ≠ 34/9 ≠ 81/16

In this context, we can reasonably infer and logically deduce that the table shows a linear relationship because as the value of time (in hours) increases, the value of distance (miles) also increases. However, it does not show a proportional relationship.
