The sine function is an odd function, so the sine of -30° is the opposite of the sine of 30°.
sin(30°) = 1/2
sin(-30°) = -1/2
The sine of 30° is greater than the sine of -30°.
ANSWER
No, because there is no common ratio
EXPLANATION
The given sequence is
-1, 1, 4, 8
If this sequence is geometric, then there should be a common ratio among the consecutive terms.
Hence the sequence
-1, 1, 4, 8
is not a geometric sequence.
Answer:
4^(-11)
Step-by-step explanation:
To divide powers, subtract the exponents.
4^(-2) / 4^9
-2-9=-11
So, the answer is 4^(-11), which is basically 4 to the eleventh power.
The right answer is Option C.
Step-by-step explanation:
Given word problem is;
Two more than three times a number is at least eight
Let,
n be the number.
Times a number = 3n
Two more means addition;
Two more than three times a number = 3n+2
At least eight means that it can either be 8 or more.
Therefore,
3n+2≥8 is the solution set.
The right answer is Option c.
