(I think I know it just checking) Which function has a period equal to half the period of the function in y=5cos(3/5x-pi)+4.. th

e period is 10pi/3
I think its the first one.

1. y=5sin(6/5x-pi)-4
2. y=-5/2sin(6/10x-2pi)+1/2
3. y=-4cos(5/6x-2pi)+5
4. y=2cos(3/10x-pi)-5/2

Answer:

y=5sin(\frac{6}{5}x- \pi )-4

Step-by-step explanation:

The given function is

y=5cos(\frac{3}{5}x- \pi )+4

Where T=\frac{10 \pi}{3}

Notice half the period is

\frac{T}{2}=\frac{\frac{10 \pi}{3} }{2}=\frac{10 \pi}{6}=\frac{5 \pi}{3}

Now, in the first function

y=5sin(\frac{6}{5}x- \pi )-4

Notice that this function is in the form: y=Asin(\omega x + \phi)

Where \omega =\frac{6}{5}, which definition is \omega = \frac{2 \pi}{T}

Replacing this value, we have

\frac{6}{5}=\frac{2 \pi}{T}\\  T=\frac{10 \pi}{6}\\ T=\frac{5 \pi}{3}

Which means the first function is has half the period of the given function.

Which algebraic expression represents “Marcus ran four times as far this week”? 4 + n 4n n – 4
disa [49]

Answer:

The Answer would be 4n

Step-by-step explanation:

Since Marcus ran four times as far this week, we need to know how far he ran last week in order to solve this expression. Since we do not know this information it becomes our variable (n). From the statement we can also infer that there is multiplication since he states the word "times". Therefore our Algebraic Expression would be the following.

P = 4n

P being distance ran by Marcus, and n being distance ran last week by Marcus.

Suppose two $20 bills, three $10 bills, one $5 bill, and seven $1 bills are placed in a bag. If you were to pull a bill at rando
Korolek [52]

Answer:

Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is \frac{7}{13}.

Step-by-step explanation:

From the given question, the bag contains;

$1 bill = 7

$5 bill = 1

$10 bill = 3

$20 bill = 2

Total number of bills in the bag = 13

Pulling a bill at random, the bills would have an expected value as follows:

For $1 bill, the expected value = \frac{7}{13}

For $5 bill, expected value = \frac{1}{13}

For $10 bill, expected value = \frac{3}{13}

For $20 bill, the expected value = \frac{2}{13}

Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is \frac{7}{13}.
