Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = 
Given
secθ = -
, then
tan²θ + 1 = (-
)² =
( subtract 1 from both sides )
tan²θ =
( take the square root of both sides )
Since
< θ < π and tanθ < 0 , then
tanθ = - 
Then
cotθ =
= - 
Answer:
13 inches
Step-by-step explanation:
length of side of cube: x
volume of cube = x³ = 2300
x = ∛2300 = 13.2
Answer:
see the explaination
Step-by-step explanation:
let x be 3:3:5
3x:3x:5x
3x is splice cookies
3x is snickerdoodle cookies
5x is no bake cookies
where 5x is equal to 45
x is equal to 45÷5=9
so x is equal to 9
now,
3x = 3×9=27
3x = 3×9=27
5x = 45 (given)
now add all, total cookies =27+27+45
=99 cookies
so there are total 99 cookies in a cookie mix
