I hated doing that stuff, it was a pain for me
Answers:
- Vertex form: y = -2(x-1)^2 + 8
- Standard form: y = -2x^2 + 4x + 6
Pick whichever form you prefer.
=============================================================
Explanation:
The vertex is the highest point in this case, which is located at (1,8).
In general, the vertex is (h,k). So we have h = 1 and k = 8.
One root of this parabola is (-1,0). So we'll plug x = -1 and y = 0 in as well. As an alternative, you can go for (x,y) = (3,0) instead.
Plug those four values mentioned into the equation below. Solve for 'a'.
y = a(x-h)^2 + k
0 = a(-1-1)^2+8
0 = a(-2)^2+8
0 = 4a+8
4a+8 = 0
4a = -8
a = -8/4
a = -2
The vertex form of this parabola is y = -2(x-1)^2+8
Expanding that out gets us the following
y = -2(x-1)^2+8
y = -2(x^2-2x+1)+8
y = -2x^2+4x-2+8
y = -2x^2+4x+6 .... equation in standard form
Answer:
hello : 6.23x10^14 > 8.912x10^12^12
Step-by-step explanation:
let : A= 6.23x10^14 and B = 8.912x10^12
A= (6.23x10^2) x10^12 ... because : 10^14 = 10^2x10^12
A = 623 x 10^12
623 > 8.912
so : A > B
Answer:
Hi there, are you sure you didn't forget any parenthesis or signs? I can't find the right answer in the options, the one that would end up at -0.2 in the end I can edit my answer if you tell me some additional option or info about the expression I need to show on the number line
Step-by-step explanation:
which number line shows correctly -0.8 + 0.6?
well lets write it in words minus eight tenths plus six tenths\
so minus:
you go 0.8 units to the left from 0,
then plus:
you go 0.6 units right from -0.8, getting to -0.2
since there is no exact answer like that we can rearrange the addends 0.6-0.8, now:
we go from 0 6 tenths units to the right and get to 0.6, then we go from 0.6 eight tenths unit to the left to get to -0.2
Answer:
There will be 2 numbers of individual bags of chocolates left with Missy.
Step-by-step explanation:
Missy bought 4 bags of chocolates and there are 8 pieces of chocolates in each bag.
Therefore, there was a total (4× 8) = 32 chocolates.
Now, her kids ate 6 of the chocolates.
So, there remains (32 - 6) = 26 chocolates left.
If Missy packed the remaining chocolates into individual bags with 13 chocolates in each bag, then there will be 
numbers of individual bags of chocolates left with Missy. (Answer)
