Jared needs 2.4 micrograms of vitamin B-12 each day. Today, Jared drank a serving of milk containing 0.44 micrograms of B-12 and ate a lamb chop containing 1.224 micrograms of B-12. Which method can Jared use to find the number of micrograms of vitamin B-12 he still needs? Subtract 1.224 – 0.44 = 1.18, then subtract 2.4 – 1.18.
Subtract 1.224 – 0.44 = 0.784, then subtract 2.4 – 0.784.
Subtract 2.4 – 0.44 = 2.356, then subtract 2.356 – 1.224.
Subtract 2.4 – 0.44 = 1.96, then subtract 1.96 – 1.224.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
