Root 3 mean pow(1/3)
n pow(3) will remove the root of 3
The correct answer is n=root of 3 (16)
The first one on right
Answer:
C. 3
Step-by-step explanation:
2/5 x = 6/5
Multiply each side by 5/2 to isolate x
5/2 * 2/5 x = 6/5 * 5/2
x = 6/2
x=3
A₁ = 9
a₂ = 9+2 → a₂ = a₁ + 2. Since it's an AP, d, the common difference is 2
1) Then the recursive formula is :
a(n) = a(n-1) + 2
2) Explicit formula:
It's an AP, with first term a₁, d= common difference and n = number of term, which is the number of rows in this problem.
the value of the nth term is given by the formula is:
value of nth term = a₁ + (n-1).d
3) Number of seats in the 12th row:
9 + (12-1).2 = 31 seats
b = 21
In this problem, we aren't finding the hypotenuse, but a side...
Using Pythagoras' theorem
side² = hyp² – side²
b² = 29² – 20²
b² = 841 – 400
b² = 441
b² = √441
b = 21
Therefore b = 21
option A is correct answer friend
