Answer:

15/49

Step-by-step explanation:

5/7 (3/14 + 3/14)

first combine like terms

3/14 + 3/14 = 6/14

then simplify by 2

6/14 to 3/7

now that both the term inside and outside have the same denominator, multiply

5/7 x 3/7 = 15/49

yan [13]

Answer:

18 days

Step-by-step explanation:

1 1/4 hours each day and 22 1/2 hours so far, so we divide 22 1/2 by 1 1/4

22 1/2÷ 1 1/4

Find an equation of the parabola with vertex (-1, -5) and directrix x=-7.
Natalka [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!

:)
