Answer:

Correct choice is A

Step-by-step explanation:

The period of the function f(t)=a\cot (bt+c) is always

T=\dfrac{\pi}{b}

(coefficients a and c do not influence).

In your case, for the function f(t)=3\cot (\pi t) the period is \dfrac{\pi}{\pi}=1.

Answer:

1


Step-by-step explanation:

Period of a sinusoidal function (here we're taking the cot x function) is \pi divided by the argument after cot ( the argument here is \pi)


Hence the period is:

Period =  \frac{\pi}{\pi}=1

Greg has decreased his running time by 1/10 minute each of the last six weeks. Write an expression to represent the total change
Nastasia [14]

x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.

Allushta [10]

Answer:

<h2>  $24</h2>

Step-by-step explanation:

The question is not complete, here is the complete question

"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>

<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24

Rewrite the given parametric equations in Cartesian from x(t) = 2t– 1 y(t) = 5t
docker41 [41]

Hi there!

\large\boxed{(-\frac{5}{3},-\frac{5}{3})}

We can begin by setting the two expressions equal to solve for t:

2t - 1 = 5t

Subtract 2t from both sides:

-1 = 3t

Divide both sides by 3:

t = -1/3

Plug in this value of t into x(t) and y(t):

x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3

y(-1/3) = 5(-1/3) = -5/3

Thus:

(-5/3, -5/3) are the corresponding coordinates.
