0.1
Step-by-step explanation:
anything after the decimal (.) becomes a sogfig
Answer:
2 sqrt(15)
Step-by-step explanation:
Using the secant tangent formula
(whole secant) x (external part) = (tangent)^2
(5+7) * 5 = x^2
12*5 = x^2
60 = x^2
Taking the square root
sqrt(60) = sqrt(x^2)
sqrt(4*15) = x
2 sqrt(15) =x

Answer:
3x^2 + 3 --> 6, 15, 30, 51
2x^2 - 1 --> 1, 7, 17, 31
x^2 + 2 --> 3, 6, 11, 18
Step-by-step explanation:
Let's start with the first equation; 3x^2 + 3
Substitute 1 (the first digit in a sequence) for x.
3(1^2) + 3
3(1) + 3
3 + 3 = <u>6</u>
3(2^2) + 3 Then the second digit.
3(4) + 3
12 + 3 = <u>15</u>
Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.
2(1^2) - 1
2(1) - 1
2 - 1 = <u>1</u>
This equation represents 1, 7, 17, 31.
These same steps apply to the other equation as well.
1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)
