1. You have that Karen made 40 cakes and she gives 1/5 to Andrew and 10% to Chris, then you have:
40 cakes=5/5=1
1/5 to Andrew⇒40x1/5=8
10% to Chris=40x0.10=4
1/5----8
x----4
x=4(1/5)/8
x=1/10
2. The fraction of the 40 cakes that she have left is:
1-1/5-1/10
Therefore, the answer is: 7/10
Answer:
Base on the vertex (h, k) and the distance p between vertex and directrix, the standard form of parabola is written as:
(x – h)^2 = 4*p(y – k)
We have (-1, -5) as vertex.
=> (x + 1)^2 = 4*p(y + 5)
Now, we find p:
The distance between (-1, -5) and x = -7 is calculated by:
|-1 -(-7)| = |6| = 6
=> (x + 1)^2 = 4*6(y + 5)
=> (x + 1)^2 = 24(y + 5)
Hope this helps!
