Answer:
The exact value of sin-1(√32) sin -1 ( 3 2 ) is π3 .
Step-by-step explanation:
I am assuming you are trying to find the sum.
First, plug in n for 1, then n for 80 to get the following numbers:
5/6 and 163/6
As you go up the sequence, as n is increased by 1, then the next number is increased by 1/3
Use the arithmetic sequence formula to solve for the sum.
n * (a1 + a2)/2 where a1 is 1st number and a2 is last number.
80 * (5/6 + 163/6)/2
Simplify the expression to get 1120.
Answer:
Probability= 22/29
Step-by-step explanation:
Total no. of marbles= 29
No of red marbles=5
No of green marbles= 2
No of marbles which are neither red nor green= 29-(5+2)
=29-7
=22 marbles
Probability= 22/29
You plug 13 into where the r is and then solve, using a calculator
Answer:
Step-by-step explanation:
f(-1)= 1 - (-1)^2 + (-1)^3 = 1 - 1 - 1 = 0 - 1 = -1
