Which of the functions below have period 2pi? Check all that apply. A. y = tan x B. y = sec x C. y = cot x D. y = csc x

Colt1911 [192]

Answer:

Option B and D are correct that is $y=secx$ and $y=cscx$ respectively.

Step-by-step explanation:

We have been given four functions:

CaseA:

$y=tanx$

$\text{Period oftanx is} \pi$

Hence, A is correct.

CaseB:

$y=secx$

$\text{Period of secx is} 2\pi$

Hence, B is correct.

CaseC:

$y=cotx$

$\text{Period of cotx is} \pi$

Hence, C is not correct.

CaseD:

$y=cscx$

$\text{Period of cscx is} 2\pi$

Hence, D is correct.

Suppose that there are 25 students in a class, each either a freshman, a sophomore, or a junior. How many students must be in th

Yakvenalex [24]

Answer:

at least 9 students in each cohort.

Step-by-step explanation:

Given that :

In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.

Let us suppose there are equal number of students in each of the cohort.

Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.

Thus, we can say that there are at least $9$ freshman, at least $9$ sophomore or at least $9$ junior in each of the cohort.
