Answer:
(-4,1)
Step-by-step explanation:
The given parabola is
When we rewrite in vertex form, we get;
Or
When we compare to:
We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)
The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1
Answer=4
8*16=128
your number is 8
therefore half your number is 4
8/2=4
Answer: the length of the second piece is 1 5/6 inches
Step-by-step explanation:
Mary had a link of yarn 4 1/3 inches. Converting 4 1/3 inches to improper fraction, it becomes 13/3 inches.
She cut it into two pieces for her art project. One of the pieces was 2 1/2 inches long. Converting 2 1/2 inches to improper fraction, it becomes 5/2 inches.
Therefore, the length of the second piece would be
13/3 - 5/2 = (26 - 15)/6 = 11/6 inches.
Converting to mixed fraction, it becomes
1 5/6 inches
