Here, Your Expression: y = 0.25 (2^x)
So, we can see the expression is "Exponential" which increases double in every hour. So, the only graph with that pattern is 3rd one.You can compare following coordinates: (1, 50), (2, 100), (3, 200)
For every 1 value of x, y increases to it's double.
In short, Your Answer would be Option C
Hope this helps!
Simplified answer: -x-123
Answer:
Vertex is (5,-9)
Step-by-step explanation:
Answer: 8+(x÷39) or (x÷30)+8
Start by getting everything on the same side of the equals sign and then set it equal to 0.
. Factor out the common tan^2x like this:
. Now we have 2 separate equations to solve:
and sinx = 0. Now we have to figure out where tan^2 is 0 between 0 and 2pi. If we include 2pi, the solutions for that equation are
. You can test those out on your calculator just to be sure. There's only one value of x for the next equation. The only place between 0 and 2pi where the sin x = 1 is at x =
. And there you go!
