Because it is BELOW sea level after 10 minutes, it straight away cannot be A) or B), because ascended means going up, so it has to be either C) or D).
I believe the answer is C), as the answer for D) would be -40 meters per minute, but it's still 40. I'm not sure though, so it's either C) or D).
Answer:
-6
Step-by-step explanation:
Substitute -2 from x meaning -2^3+-2^2-3*-2; solve this, you get -6!
Answer:
Step-by-step explanation:
192 ÷ 420 = 0.457
0.457 x 100 = 45.7
But there can't be a percentage increase or decrease because there is no percentage to compare it to, there should be information for the change in students of the last year
183.26 times .25 = 45.815
183.26 minus 45.815 = 137.445
137.445 times 0.09 = 12.37005
137.445 plus 12.37005 = 149.81505
Which =149.82 rounded
First we will convert those radian angles to degrees, since my mind works better with degrees. Let's work one at a time. First,
. If we start at the positive x-axis and measure out 315 we end up in the 4th quadrant with a reference angle of 45 with the positive x-axis. The side across from the reference angle is -1, the side adjacent to the angle is 1, and the hypotenuse is sqrt2. The cotangent of this angle, then is 1/-1 which is -1. As for the second one, converting radians to degrees gives us that
. Sweeping out that angle has us going around the origin more than once and ending up in the first quadrant with a reference angle of 30° with the positive x-axis. The side across from the angle is 1, the side adjacent to the angle is √3, and the hypotenuse is 2. Therefore, the secant of that angle is 2/√3.
