Answer:
A and C
Step-by-step explanation:
Easiest way is to plug in values of t and trace the graph.
A (x, y) = (sin(t), cos(t))
At t = 0, (x, y) = (0, 1).
At t = π/2, (x, y) = (1, 0).
So the particle starts at (0, 1) and moves clockwise. The period of sin(t) and cos(t) is 2π, so for 0 < t < 2π, the particle makes 1 revolution.
B (x, y) = (-sin(t), cos(t))
At t = 0, (x, y) = (0, 1).
At t = π/2, (x, y) = (-1, 0).
So the particle starts at (0, 1) and moves counterclockwise. The period of sin(t) and cos(t) is 2π, so for 0 < t < 4π, the particle makes 2 revolutions.
C (x, y) = (cos(4πt), sin(4πt))
At t = 0, (x, y) = (1, 0).
At t = 1/8, (x, y) = (0, 1).
So the particle starts at (1, 0) and moves counterclockwise. The period of sin(4πt) and cos(4πt) is 1/2, so for 0 < t < 1, the particle makes 2 revolutions.
D (x, y) = (cos(2πt), -sin(2πt))
At t = 0, (x, y) = (1, 0).
At t = 1/4, (x, y) = (0, -1).
So the particle starts at (1, 0) and moves clockwise. The period of sin(2πt) and cos(2πt) is 1, so for 0 < t < 1, the particle makes 1 revolution.

Step-by-step explanation:
[tex]2 \frac{3}{5} miles = \frac{10}{5} + \frac{3}{5} \: miles = \frac{13}{5} \: miles \\ [/tex]
So Michael lives 13/5 miles away from the school.
_________________________________
Sarah lives 1/2 as long as Michael.
So the distance from the school of where Sarah's house located is 1/2 distance from the school of where Michael's house located.
Which means :
[tex] \frac{13}{5} \div 2 = \frac{13}{5} \times \frac{1}{2} = \frac{13}{10} \\ [/tex]
And we're done.
Thanks for watching buddy good luck.

Answers
Answer:
To find the percentage of something you must multiply it by that number divided by 100. So if it were 25% then you would times 300 by 0.25.
in this case though it is 40% of three hundred, so you would make it a decimal and times 300 by 0.4. which would result in 120 miles

In 1982 John Hinckley was on trial, accused of having attempted to kill the then US President Ronald Reagan. Hinckley was found not guilty by reason of insanity. The defense psychiatric reports found him to be insane while the prosecution reports declared him legally sane. In particular, the defense sought to establish that brain scan results like John Hinckley's appeared in a higher percentage of schizophrenics than of normal people his age.
During Hinckley's trial, an expert witness, Dr. Weinberger, told the court that when individuals suffering from schizophrenia were given computerized axial tomography (CAT) scans, the scans showed brain atrophy in 30% of cases compared with only 2% of scans done on normal people. Health records show that 1.5% of the people in the United States suffer from schizophrenia. Hinckleys CAT scan showed brain atrophy. Calculate the probability that Hinckley suffered from schizophrenia given his CAT scan showed brain atrophy.
Answers
Answer:
O.186 or 18.6%
Step-by-step explanation:
Let s = event of schizophrenia
B = brain atrophy
From our question we have:
P(s) = probability of those suffering from schizophrenia = 1.5% = 0.015
P(B|S) = probability of brain atrophy = 30% = 0.30
P(S') = 1 - 0.015 = 0.985
P(B|S') = 2% = 0.02
Probability Hinckley suffered from schizophrenia
= P(S|B) = P(B|S)P(S)/P(B|S)P(S)+P(B|S')P(S')
= (0.30x0.015)/(0.30)*(0.015)+(0.02)(0.985)
= 0.0045/0.0045+0.0197
= 0.0045/0.0242
= 0.185950
This is approximately 0.186 or 18.6%

In how many ways can we write a number using the digits (0,2,3,5) and the number is greater than 100
Answers
This is a multiplicative principle's question. Let's think how we can solve that.
If we want numbers are greater than 1000, so we need numbers with 4 digit (for example: 1001, 2350 and so on).
Imagine that we need to complete four spaces: one thousands, hundreds, tens and ones. See below how to compelete each space:
One thousands: In this space, we can't use the number 0, because in this way, the number will have 3 digits and we want number with 4 digits (for example: 0235 is a 3 digits number). Therefore, we can use the numbers 2, 3 and 5 to complete this space. So, there are 3 possibilities.Hundreds: Now, we can use the number 0 and the number won't have 3 digits (for example: 2035 is a 4 digits number). Therefore, we can use the numbers 0, 2, 3 and 5 to complete this space. So, there are 4 possibililities.Tens: Ih this case, it happens the same thing that happen in the case of hundreds. Therefore, there are 4 possibilites.Ones: Finally, in this case it also happens the same thing that happen in the case os hundreds. So, there are 4 possibilites.For multiplicative principle, we just need multiply these numbers of possibilities to find the result of this question:
[tex]3\times4\times4\times4=192[/tex]
Therefore, we can write 192 numbers using the digits (0, 2, 3 and 5) and all these numbers are greater than 1000.

Then put 1500 as the denominator and 300 as the numerator since we're talking about the number of students that did NOT wear their school colors. our fraction should then be 300/1500.
If you cross out 2 zeros on both numbers, you'll get 3/15. if you reduce that you get 1/5. 1/5= 20%

How is multiplying complex numbers different
from adding or subtracting complex numbers?
Answers
Let P and Q be two complex numbers such that
P = a+bi
Q = c+di
Where a,b,c,d are real numbers and i = sqrt(-1).
This means i^2 = -1.
-------------------
Adding P and Q means
P+Q = (a+bi)+(c+di)
P+Q = a+bi + c+di
P+Q = (a+c) + (bi+di)
P+Q = (a+c) + (b+d)i
As you can see, we just add the corresponding components together.
-------------------
Subtraction is a similar story.
P-Q = (a+bi)-(c+di)
P-Q = a+bi - c-di
P-Q = (a-c) + (bi-di)
P-Q = (a-c) + (b-d)i
We subtract the corresponding components
-------------------
Multiplication is a bit more complicated.
We'll use the FOIL rule
P*Q = (a+bi)*(c+di)
P*Q = a*c + a*di + bi*c + bi*di
P*Q = a*c + ad*i + bc*i + bd*i^2
P*Q = a*c + ad*i + bc*i + bd*(-1)
P*Q = a*c + ad*i + bc*i - bd
P*Q = (ac - bd) + (ad*i + bc*i)
P*Q = (ac - bd) + (ad + bc)i
Unfortunately multiplication isn't as simple as addition or subtraction, but we can at least make a tidy formula for it. You could also use the box method to visually organize the terms into a table to help multiply out P and Q.
