Take a quick peek at
brainly.com/question/10417591that's how you test for the y-axis, x-axis and origin
recall your symmetry identities, cos(- θ) = cos(θ)
so, simply replace θ for those values, and if the resultant function looks exactly like the original, then it has that symmetry.
Your problem is an example of a distance problem, so you muct know the formula to find the distance. To find the distance we simply multiply the rate by the time, or as you'll see more often, d = r t. That means to calculate distance traveled you need rate and time.
Take note, planes are traveling in opposite direction, which means 2000 miles will be the sum of the distances that the two planes have traveled.
D (Plane 1) + D(Plane 2). = 2000
Let t = time in minutes
560t + 500t = 2000
Solve for t. Take it ftom here.
Answer: A
Step-by-step explanation:
Because 2x3=5
Step-by-step explanation:
Letting the variable x approach 1 will give us , an indeterminate result. In such a case, we can use L'Hopital's rule where
Let and
We can see that
and
Applying L'Hopital's rule, we get
Therefore, as the given expression approaches .
B = no. of buses
v = no. of vans
b + v less than or equal to 8 ( there are only 8 drivers, but don't have to use them all)
51b + 8v greater than or equal to 193 (the number of seats must be at least 193 but there can be spares)
So these are the inequalities to solve. I did start doing a linear programming graph but the second inequality is horrible so I hope you don't need to actually solve them.
