An Olympic sized swimming pool of uniform depth measures 50 meters by 21 meters. The bottom of the pool is treated with a sealer, and one galloon of the sealer covers 3000 sq feet of surface. How many galloons will be required for the job? Round to the nearest whole galloon.

anser is a

step-by-step explanation:

negitive slope

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
