#10 Weekly sales in thousands) of a new basketball shoe
decrease steadily for a while and then increase as
described by the function
f(t) = 2t - 15 + 50
where t is the time (in weeks).
How many pairs of shoes (in thousands) sold in 5
weeks?

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
