The landscaper pours 200 gallons of herbicide in a pond. the herbicide degrades 10% each week. the landscaper will put another dose in the pond when the herbicide level drops below 50 gallons. in about how many weeks will he need to add more herbicide?

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

slope is 2
