<h3>Answers are:
sine, tangent, cosecant, cotangent</h3>
Explanation:
On the unit circle we have some point (x,y) such that x = cos(theta) and y = sin(theta). The sine corresponds to the y coordinate of the point on the circle. Quadrant IV is below the x axis which explains why sine is negative here, since y < 0 here.
Since sine is negative, so is cosecant as this is the reciprocal of sine
csc = 1/sin
In quadrant IV, cosine is positive as x > 0 here. So the ratio tan = sin/cos is going to be negative. We have a negative over a positive when we divide.
Because tangent is negative, so is cotangent.
The only positive functions in Q4 are cosine and secant, which is because sec = 1/cos.
0, 2, 4, 6 is because the rule it to add 2
1, 2,4,8 is a geometric sequence since the rule is to mutliply by 2
1,4,8, 13 is neither even though there is a pattern add 3, add 4 add 5 etc.
Answer:
The last one is the answer ....
<u>help me by marking as brainliest....</u>
the answer would be 42.9 because the final answer (not rounded) would be 42.8888 however if you round the 8 you get 42.9
7.8 * 10^5=since the exponent is positive 5. Then the 7.8 you move the decimal 5 places to the right to be
780000
