Each song downloaded costs 3 points
each video costs 40 points
total of 999 points
if each song cost 3 points and she has 999 points to use she can download 333 songs at max
Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]
Answer:
D 15
Step-by-step explanation:
5x when x=3
=5×3
=15
True
As it is said in the question the probability of getting a head is 0.5. And, if we toss it two times it will be 0.25.
We'll have to multiply 0.5 with 0.5.
If two plus two is four therefore two plus three is in fact five.
