B
It was 3 degrees below so the 3 will be a negative 3. Then by 10 it rose up by 3 so it is a positive 3. So -3+3=0
This type of problem can be decided by looking at whether the function is positive or negative in the vicinity of the zeros. There are three roots: -12, -6, and 2 at which the function is clearly 0. Look at the four intervals the x axis:
interval x<-12: function is negative (just test using a number <-12, say, -13)
interval (-12,-6): function is positive
interval (-6, 2): function is negative
interval x>2: positive
From the above you deduce that at the roots the function must be crossing the x-axis (as opposed to just touching it) because the function value changes its sign every time.
Answer:
16/3 or 5.3
Step-by-step explanation:
The answer is 65.35
80 | 100
52 | 65.35
80/52 = 1.53
100/1.53 = 65.35
Answer: 3944
All you have to do is multiply 58 x 68 to get the answer.
