determine if f, g, and h are true or false. If false, correct the statement with an explanation

Answers

We need to determine if the statements are true or false.

In order to do so, we need to pay attention to the following notations:

[tex]\begin{gathered} (\sin x)^{-1}=\frac{1}{\sin x} \\ \\ \sin^{-1}x=\text{ inverse function of }\sin x \end{gathered}[/tex]

The same notations apply to cosine and tangent functions.

The inverse f⁻¹(x) is the function such that:

[tex](f^{-1}\circ f)(x)=f^{-1}(f(x))=x[/tex]

Thus, we have:

[tex]\cos^{-1}(\cos(\frac{15\pi}{6}))=\frac{15\pi}{6}[/tex]

Therefore, statement g. is true.

In order to show that statements f. and h. are false, let's see what happens for x = 1/2:

[tex]\begin{gathered} \frac{\sin^{-1}(\frac{1}{2})}{\cos^{-1}(\frac{1}{2})}=\frac{\frac{\pi}{6}}{\frac{\pi}{3}}=\frac{3}{6}=0.5\text{ \lparen no units\rparen} \\ \\ \tan^{-1}(\frac{1}{2})\cong0.46\text{ \lparen rad\rparen} \\ \\ \Rightarrow\frac{\sin^{-1}(\frac{1}{2})}{\cos^{-1}(\frac{1}{2})}\ne\tan^{-1}(\frac{1}{2}) \end{gathered}[/tex][tex]\begin{gathered} \sin^{-1}(\frac{1}{2})=\frac{\pi}{6}\cong0.52 \\ \\ \frac{1}{\sin(\frac{1}{2})}\cong2.09 \\ \\ \Rightarrow\sin^{-1}(\frac{1}{2})\ne\frac{1}{\sin(\frac{1}{2})} \end{gathered}[/tex]

Answer:

f. False

g. True

h. False

Notice that we can correct the statements f. and h. by using the correct notation:

[tex]\begin{gathered} \text{ f. }\frac{(\sin x)^{-1}}{(\cos x)^{-1}}=(\tan x)^{-1} \\ \\ \text{ h. }(\sin x)^{-1}=\frac{1}{\sin x} \end{gathered}[/tex]

Sketch the velocity graph and determine when is the object moving in the positivedirection.b. Draw a diagram of the motion of the object and determine the total distancetraveled during the first 6 seconds.

Answers

SOLUTION

(a) The function given is the distance graph. The velocity fuction is the derivative of the distance function. This becomes

[tex]\begin{gathered} f(t)=t^4-4t+1 \\ f^{\prime}(t)=4t^3-4 \\ v=4t^3-4 \end{gathered}[/tex]

the graph is shown below

From the velocity graph above, the function is moving in a positive direction from 1 second and beyond

(b) The diagram of motion of the object is shown in the distance graph below

The total distance travelled is the integral of the velocity function from 0 to 6 as shown below

[tex]\begin{gathered} \int_0^64x^3-4 \\ =[\frac{4x^4}{4}-4x]_0^6 \\ =[x^4-4x]_0^6=6^4-4(6)-(0^4-4(0)) \\ =1296-24-0 \\ =1272 \end{gathered}[/tex]

A bag contains 42 red, 42 green, 20 yellow, and 32 purple candies. You pick one candy at random. Find the probability that it is purple or not red

Answers

The probability of a candy when randomly taken is purple or not red is 0.235

Given,

Number of red candies in the bag = 42

Number of green candies in the bag = 42

Number of yellow candies in the bag = 20

Number of purple candies in the bag = 32

We have to find the probability of a candy when randomly taken is purple or not red.

Probability, P(E) = Number of favorable outcomes / Total number of favorable outcomes

Here,

Number of favorable outcomes = 32

Total number of favorable outcomes = 42 + 42 + 20 + 32 = 136

Madison is in the business of manufacturing phones. She must pay a daily fixed cost of $400 to rent the building and equipment, and also pays a cost of $125 per phone produced for materials and labor. Make a table of values and then write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.

Answers

The equation that represents the total cost is C = $400 + $125p .

What is the total cost?

The equation that represents the total cost is a function of the fixed cost and the variable cost. The fixed cost remains constant regardless of the level of output. The variable cost changes with the level of output.

Total cost = fixed cost + total variable cost

Total cost = fixed cost + (variable cost x total output)

C = $400 + ($125 x p)

C = $400 + $125p

Total cost when 0 phones are made =  $400 + $125(0) = $400

Total cost when 1 phone are made =  $400 + $125(1) = $525

Total cost when 2 phones are made =  $400 + $125(2) = $650

Total cost when 3 phones are made =  $400 + $125(3) = $775

Which of the following could be the end behavior of f(x) = -x2 – 4?

Answers

Answer:

f(x) = -∞ as x → ±∞

Explanation:

The given function is

f(x) = -x² - 4

To know the end behavior, let's replace x by a greater number and by a smaller number, so

If x = 100

f(x) = -100² - 4

f(x) = -10000 - 4

f(x) = -10004

If x = -100

f(x) = -(-100)² - 4

f(x) = -10000 - 4

f(x) = -10004

So, we can see that no matter if x is negative or positive, the value of f(x) will be positive. Then, we can say that the end behavior is

f(x) = -∞ as x → ±∞

Option C is the correct answer

Here, we want to select which of the equations in the option is perpendicular to the given equation

Firstly, we need to understand that for two equations to be perpendicular, then the product of their slopes must be equal to -1

Before we proceed to compare, we need to write the equation in the general form

The equation of the line written in the general form will be;

[tex]y\text{ = mx + b}[/tex]

where m represents the slope and the term b represents the y-intercept

Now, let us proceed to write the equation in the standard form;

We have this as;

[tex]\begin{gathered} 3y\text{ = -2x + 12} \\ \\ y\text{ = -}\frac{2}{3}x\text{ + 4} \end{gathered}[/tex]

Compared with the general form, we can see that the slope of this line is -2/3

Now let us get the slope of the line that would be perpendicular to it;

[tex]\begin{gathered} \frac{-2}{3}\times\text{ m = -1} \\ \\ m\text{ = }\frac{3}{2} \end{gathered}[/tex]

Now, the equation perpendicular to what was given will have a slope of 3/2

I need help with a table to plot the points

Answers

In order to plot a set of coordinates on a graph page, you would need to take account of every pair of x and y values provided. The line that goes horizontally is the x-axis (from left to right). All the negative values move from point zero (the origin).

The ordered pair, or the coordinates tells you where x and y intersect. For example, the first set of coordinates are (2, 9). That means, when x is 2, then y is 9.

Observe that x equals 2 on the right side of the horizontal axis. Next, you look for the spot where y equals 9.

Next step, you carefully trace the spot where x is 2, and trace it up a straight line and at the point where y equals 9 (at the upper part of the y axis), you put a tiny "X" to mark the spot where both values intersect.

Notice that while tracing from x, you move upwards, and while tracing from y, you move towards the right. That point defines the coordinates (2, 9) which is the first line on your table.

You follow a similar step for every one of the other coordinates, which are;

[tex]\begin{gathered} (2,9) \\ (4,3) \\ (6,-6) \\ (0,15) \\ (3,6) \\ (5,0) \\ (\frac{7}{3},8) \end{gathered}[/tex]

Please note that I've just attached the same graph, but this time I've labelled the points one by one.

What is meant by Pythagoras connection?

The Pythagorean theorem, or Pythagorean theorem, explains the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to Pythagoras' theorem.

From the diagram, the formation is a rectangle.

Use the coordinate points to find the measurements of each side.

Side length AD = Side length BC

Apply the Pythagoras connection to find length BC as;

a² + b²= c² where a=2 cm and b = 4 cm and c =BC

2² + 4² = c²

4+16 = c²

20 = c²

c= √20 = 4.4721

Length BC = Length AD = 4.5 cm

Side length AB = Side length DC

Apply the Pythagoras connection to find the length DC as;

a² + b²= c² where a=6 cm and b = 3 cm and c =DC

6² + 3² =c²

36 + 9 = c²

45 = c²

√45 = c

c= 6.7082

c = DC = 6.7 cm

Now you have the dimensions of the rectangle as;

Length = 6.7 cm and width = 4.5 cm

The perimeter will be ;

P= 2{l +w} --------- where l is length and w is width and P is the perimeter of the rectangle

P=2{6.7 + 4.5}

P=2{11.2}

P= 22.4 cm

The area will be ;

A= l*w

A= 6.7 * 4.5 = 30.15 = 30.2 cm²

The perimeter of the figure is: 22.4 cm

The area of the figure is: 30.2 cm²
