Remember the arc is equal to the central angle, so ab will equal angle APB. they told you angle APB is a right angle, how many degrees is this? that is what ab will be also:)
The slope of the line is 
(or just 2) as it rises by 2 units and runs to the left by 1 unit.
Write and solve the appropriate exponential equation:
228 = 16(r)^4, where r is the change per hour in the number of bacteria:
228
------ = r^4 = 14.25.
16
Taking the fourth root of both sides, we get: r = 1.94 (answer)
Answer:
x < 3
Step-by-step explanation:
When you multipy an inequality by a negative, remember to switch the inequality sign!
-x > -3
(-x)(-1) > (-3)(-1)
x < 3
