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.

Svetlana hair is 4 centimeters long. Her hair grows 1.5 cm per month. Svetlana wants her hair to grow so at least 7 cm long. Wri

Andrei [34K]

Let "per month" = m

The inequality is

1.5m + 4 ≥ 7

+ 4: Her hair right now is 4 cm long

1.5m: Her hair grows 1.5 per month (m)

≥ 7: She wants it to be at least 7 or more.

1.5m + 4 ≥ 7 is your answer

hope this helps
