Answer:
B. The slopes of the graphs are the same and the y-intercepts of the graphs are different
Step-by-step explanation:
The lines will also be parallel
First, we get ax^2+bx+c. Next, we know that the line of symmetry is -b/2a. Since we know that there is a maximum value, the parabola is facing downwards, so a is negative. For random numbers, we can say that a = -0.5 and b=-10 (b needs to be negative for -b/2a to equal -10), getting -0.5x^2-10x+c. Plugging -10 in for x (since -10 is the middle it is the max), we get -50+100=50. Since the maximum needs to be 5, not 50, we subtract 45 from the answer to get it and therefore make c = -45, getting -0.5x^2-10x-45
Answer:
I'm pretty sure it's none of the above

Sorry if you get it wrong :/
Answer:
1364
Step-by-step explanation:
∑ means that to add values
So n goes from 1 to 5 and you have to add them from 1 to 5
∑n=1 to 5 4^n = 4^1 + 4^2 + 4^3 + 4^4 + 4^5
4^n means that 4 is n times if 4^3 its mean that 4 is 3 times
= 4 + 16 + 64 + 256 + 1024
= 1364 Answer
I hope you got the idea. Thanks
