It means that you need to divide 42 on both sides
42x/42=7/42

Answer:
t = 1/8 ± √(1 − 4d) / 8
Step-by-step explanation:
d = -16t² + 4t
Move everything to the left side:
16t² − 4t + d = 0
Solve with quadratic formula:
t = [ -(-4) ± √((-4)² − 4(16)(d)) ] / 2(16)
t = [ 4 ± √(16 − 64d) ] / 32
t = [ 4 ± 4√(1 − 4d) ] / 32
t = [ 1 ± √(1 − 4d) ] / 8
t = 1/8 ± √(1 − 4d) / 8
Answer:
I believe D should be the correct answer
A.
Pi = 3.1
Sqrt of 2 = 1.4
Sqrt of 4 times 4 = 8
Sqrt of 16 = 4
B.
Least to greatest:
Square root of 2
Pi
4 Times Square root of 4
Square root of 16
To find the 50th term in this sequence, first you need to find how what the sequence is. To get from 5 to -2 you're subtracting 7, to get from -2 to -9, you subtract another 7. In order to get the next number you go down by multiples of 7: 5 - 7 = -2; 5 - 14 = -9 and so on). So all you have to do is multiply 7 by 50 to get 350 and subtract that from 5 to get -345.
