The number of pairs of shoes sold s (in thousands) increases and then decreases as described by the function s( t ) = - 2 | t - 15 | +50, where t is the time (in weeks).

what is the greatest number of pairs of shoes sold in 1 week?

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

make sure you have version 2.50

try looking in the very back of the book : )

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

a.)the line for function b is steeper
