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)
Answer:
25 cups of flour

The average speed of the delivery truck would be 136.5
350 words per page.
70 words per minute
It will take her 5 minutes to type 350 words. 70 x 5 = 350.
She has to write 15 pages.
350 words x 15 pages = 5250 words in total.
5250 words total ÷ 70 words per minute = 75 minutes.
Since 60 minutes is in 1 hour we're left with 15 extra minutes.
Therefore, it'll take her 1 hour and 15 minutes to type her research paper.
True, because "or" is a logical sum.
true = 1
false = 0,
sum (1+0) = 1, true.
