Answer 1

Answer:

  see attached

Step-by-step explanation:

The left piece is a little tricky because it does not intersect the y-axis. You know it has a slope of -1, so it will be 1 unit higher than the y-intercept when it is 1 unit left of the y-axis. It ends at (-1, 3). The end point is not included in the definition of the relation, so an open circle is shown.

The right piece crosses the y-axis at y=-3, and has a slope of 2. It ends at (-1, -5). This end point is included, so a solid dot will be found at (-1, -5).

The relation is doubly-defined at x = -1, so there is another solid dot at (-1, -2).

__

Additional comment

It is incorrect to call this a function, because it fails the vertical line test at x = -1. There are two points on that vertical line. (You may want to discuss this question with your teacher.)

A message in a bottle is floating on top of the ocean in a periodic manner. The time between periods of maximum heights is 20 seconds, and the average height of the bottle is 10 feet. The bottle moves in a manner such that the distance from the highest and lowest point is 4 feet. A cosine function can model the movement of the message in a bottle in relation to the height.

Part A: Determine the amplitude and period of the function that could model the height of the message in a bottle as a function of time, t. (5 points)

Part B: Assuming that at t = 0 the message in a bottle is at its average height and moves upwards after, what is the equation of the function that could represent the situation? (5 points)

Part C: Based on the graph of the function, after how many seconds will it reach its lowest height? (5 points)

Answers

Answer:

See below for answers and explanations for each part (along with attached graph)

Step-by-step explanation:

Recall the equation [tex]f(x)=asin(bx+c)+d[/tex] where [tex]a[/tex] is the amplitude, [tex]\frac{2\pi}{b}[/tex] is the period, [tex]-\frac{c}{b}[/tex] is the phase/vertical shift, and [tex]d[/tex] is the midline

Part A

The amplitude is half the distance between the maximum/minimum, therefore, the amplitude is [tex]a=\frac{4}{2}=2[/tex]Also, we are given that the period is 20 seconds, which means that if [tex]\frac{2\pi}{b}=20[/tex], then [tex]b=\frac{\pi}{10}[/tex]

Part B

Since [tex]f(x)=sin(x)[/tex] begins at its average and we use the identity [tex]sin(x)=cos(x-\frac{\pi}{2})[/tex] to represent the wave traveling up first, then we have [tex]c=-\frac{\pi}{2}[/tex], making the phase shift [tex]-\frac{c}{b}=-\frac{-\frac{\pi}{2}}{\frac{\pi}{10}}=5[/tex], or 5 feet to the rightWe also know that the average, or the midline, must be [tex]d=10[/tex], making our equation [tex]f(t)=2cos(\frac{\pi}{10}t-\frac{\pi}{2} )+10[/tex] as a function of [tex]t[/tex]

Part C

If you review the attached graph, you will see that when [tex]t=15[/tex], then the bottle will reach its lowest height of 8 feet

I hope these explanations and the attached graph help you understand sinusoidal functions better! Please mark this answer brainliest if you found this answer helpful!

a) The amplitude of the function is 4 feet.

b) The function that represents the situation is [tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex].

c) The bottle will take 15 seconds to reach its lowest height.

How to find a function for the height of a bottle and how to analyze its motion

a) The amplitude ([tex]A[/tex]), in feet, is equal to the difference between highest and lowest point ([tex]y_{max}[/tex], [tex]y_{min}[/tex]), in feet, divided by 2. The period ([tex]T[/tex]), in seconds, is the time taken by the bottle to complete one cycle. In this case, the period is the time between two maxima. Hence, we proceed to determine each variable:

Amplitude ([tex]y_{max} = 14\,ft[/tex], [tex]y_{min} = 6\,ft[/tex])

[tex]A = \frac{14\,ft-6\,ft}{2}[/tex]

[tex]A = 4\,ft[/tex]

The amplitude of the function is 4 feet. [tex]\blacksquare[/tex]

Period

The period of the function is 20 seconds. [tex]\blacksquare[/tex]

b) The function that represents the situation is based on this model:

[tex]y(t) = y_{o} + A \cdot \sin \frac{2\pi\cdot t}{T}[/tex] (1)

Where:

[tex]y_{o}[/tex] - Average height of the bottle, in feet.[tex]t[/tex] - Time, in seconds. [tex]y(t)[/tex] - Current height, in feet.

If we know that [tex]A = 4\,ft[/tex], [tex]y_{o} = 10\,ft[/tex] and [tex]T = 20\,s[/tex], then the function that represents the situation is:

[tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex] (2)

The function that represents the situation is [tex]y(t) = 10 +4\cdot \sin \frac{\pi\cdot t}{10}[/tex]. [tex]\blacksquare[/tex]

c) With the help of a graphic tool, we graph the function in time. According to the image, the bottle will take 15 seconds to reach its lowest height. [tex]\blacksquare[/tex]

What is the equation of the nine that passes through

Answers

Answer:

y 6/5x-2

Step-by-step explanation

Answer:

y = [tex]\frac{6}{5}[/tex] x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{6}{5}[/tex] , then

y = [tex]\frac{6}{5}[/tex] x + c ← is the partial equation

To find c substitute (5, 1 ) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = [tex]\frac{6}{5}[/tex] x - 5 ← equation of line

50 = x^2

[tex]\sqrt{50}[/tex] = x,   5[tex]\sqrt{2}[/tex]

x = approximately 7.07

Answer:

Exact: SQRT 50

Approx: 7.07

Step-by-step explanation:

you take both of the 5s and square them.

So 5*5=25 and 5*5 is 25. Since the right angle is opposite the side you are trying to find you add those together to get 50. Then you take the SQRT of 50 because you are trying to solve for x via the pythagorean theorem.

So the exact is SQRT 50

and the approx is 7.07

Equation: y = 3x + 9

Step-by-step explanation:

To find equation:

Take two coordinates:  ( 1 , 12 ) , ( 2 , 15 )

Secondly find slope: ( y2 - y1 ) / (x2 - x1 )

Using the formula:     ( 15 - 12 ) / ( 2 - 1 )

                             :          3 ............this is our slope, m

Using formula to find equation: y - y1 = m ( x - x1 )

                                                    : y - 12 = 3 ( x - 1 )

                                                    : y = 3x - 3 + 12

                                                    :  y = 3x + 9  .....our final answer.

The equation in slope intercept form is y = 3x + 9

A. y = 3/4x - 1/4

What is the simple interest

Answers

Answer:

5%

Step-by-step explanation:

Let the interest rate be x100

So we have for simple interest: x100×$2600=$390

This is the same as: ddddddddddx×$2600100=$390

x×$2600100=$390

Divide both sides by $26.

x×$26$26=$390$26

x×1=$390$26

x=15

But x is from x100

The % symbol is like a unit of measurement and one that is worth 1100

So 15100d→d15×1100d→d15×%→15%
