Cerrena [4.2K]
Answer:
A
Step-by-step explanation:
In a list of ordered pairs, a relation that is a function will not have any repeated x-values.
A -- a function (x-values are {-1, 0, 2, 5} with no repeats)
B -- irrelevant
C -- not a function (x-values are {0, 0, -3, 3} with 0 being repeated)
D -- not a function (x-values are {-2, -1, -2, 2} with -2 being repeated)
Answer:
Step-by-step explanation:
The directrix given is vertical , so we will use the formula :
P is the distance between the focus , that is 5 - 0 = 5
Therefore : p = 5
(h,k) is the mid point between the focus and the directrix , that is
(h,k) = = =
Therefore:
h =0
k = 0
substituting into the formula : we have
= 4(5)(
Therefore : the equation in vertex form is
I(interest rate)=P(principle)R(rate)T(time)
I=112*1400*1
I=$156800
