Hello from MrBillDoesMath!
Answer:
Choice B (value 8)
Discussion:
First, g(1) = 2(1) = 2 so
h (g(1)) = h (2) = 2^2 + 4
= 4 + 4
= 8
which is choice B
Thank you,
MrB
Every point on a line satisfies the equation of that line.
If two lines intersect at one point, that point is a point on both lines, so it must satisfy both lines. Since two different lines can intersect at most at one point, that point is the only point that makes the two equations true.
Answer:
Uuuuh thats kind of suspicious, maybe you could post your question without a link? But links are usually scams, so dont do that :)
Cot(5pi/12) = tan(pi/12)
tan(x/2) = (1 - cos(x)) / sin(x))
tan(pi/12) = tan((pi/6)/2) = (1 - cos(pi/6)) / sin(pi/6))
sin(pi/6) = 1/2
cos(pi/6) = sqrt(3) / 2
so...
tan(pi/12) = (1 - sqrt(3)/2) / (1/2) = 2 - sqrt(3)
Answer: C
Step-by-step explanation:
In this problem, you will need to know the different properties of the equation. Which part tells you if this graph is negative or positive? and more.
First, we notice an x as the exponent. This tells us that this is an exponential equation. Therefore, we can eliminate B and D.
Next, how do we know if the equation is growth or decay?
The 3 and 1.5 are both positive. This tells us that this is equation is exponential growth.
You can always graph the equation to make sure you are correct.
