The equation yˆ=105.416x+1249.309 models the amount of money, in dollars, a charity raises during an annual event when x people attend the charity dinner. what does the y-intercept of the equation represent in context of the situation? it costs the charity $105 to host the dinner. if no one came to the dinner, the charity would still raise about $1250. if no one came to the dinner, the charity would still raise about $105. it costs the charity $1250 to host the dinner.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
