Answer:
C. 1/(4a)
Step-by-step explanation:
We assume you're comparing the vertex form ...
y = a(x -h)^2 +k
to the form used to write the equation in terms of the focal distance p.
y = 1/(4p)(x -h)^2 +k
That comparison tells you ...
a = 1/(4p)
p = 1/(4a) . . . . . . multiply by p/a; matches choice C

<em>Additional comment</em>
When using plain text to write a rational expression, parentheses are needed around any denominator that has is more than a single constant or variable. The order of operations requires 1/4a to be interpreted as (1/4)a. The value of p is 1/(4a).
When rational expressions are typeset, the fraction bar serves as a grouping symbol identifying the entire denominator:
Answer:
it is -4
Step-by-step explanation:
but the answer is not on there so the answer will be D.
Hey there! Let's figure this question out for you!
A math conjugate, is formed by changing the sign between two terms in a binomial.
An example would be:
4+7x would become 4 - 7x.
I hope this helps!
To find how many bags the store needs to sell, you have to divide 5225 by 5.50.
Hi there!
Let's solve this problem step by step!
The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 ×
the amount of golf plays, mathematically $18 × g, hence 18g
The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 ×
the amount of months, mathematically $250 × m, hence 250m.
Now we can set up the equation. The only thing we need to do is adding up the individual functions.
Answer:
C = 250m + 18g
