Sarah owns a flower shop and can model the profits from selling springtime bouquets using this equation, where b is the number of springtime bouquets. P=-5b^2 + 450b - 1000

Which statement is true if Sarah needs to make a profit of at least $9,000?

A.
Sarah must sell between 0 and 40 springtime bouquets.
B.
Sarah must sell between 40 and 50 springtime bouquets.
C.
Sarah must sell more than 50 springtime bouquets.
D.
Sarah must sell more than 90 bouquets.

Sarah must sell more than 50 bouquets.

Step-by-step explanation:

Plug in 50 for b

p=-5(50)^(2)+450(50)-1000

your answer will be 9000, aka the amount of money she needs,

hope this helped!

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

answer: 59
