Answer:
3.7m/s^2
Step-by-step explanation:
T is given as 3.27 seconds
L= 1m
we have to find g just put values in given formula
3.27s=2pi(sqrt(1m/g))
3.27s/2pi=(sqrt(1m/g))
0.520s=(sqrt(1m/g))
Taking square on both side to eliminate square root
0.27085s^2=1m/g
Multiply with g on both sides
0.27085 s^2*g=1m
Divide both sides with 0.27085
g=1m/0.27085s^2
g=3.7m/s^2
Answer:
c
Step-by-step explanation:
1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74
2,11,26,47,74
Answer C. 2,11,26,47,74.
Answer:
3/4
Step-by-step explanation:
Let the number = x
Nine times the number = 9x
Hence, 9x - 6 = x
9x - 6 = x
9x - x = 6
8x = 6
∴ x = 6/8 = 3/4
The absolute value of 1 1/4 is -1 1/4
the absolute value of -11/6 is 11/6
