Acircular oil spill continues to increase in size.
the radius of the oil spill, in miles, is given by the
function r(t) = 0.5 + 2t, where t is the time in hours.
the area of the circular region is given by the
function a(n) = trr2, where r is the radius of the
circle at time t.
explain how to write a composite function to find
the area of the region at time t.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

only 2 outcomes have passed the given condition.

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
