A text message plan costs $7 per month plus $0.14 per text. Find the monthly cost for x text messages
a. Considering the context of the problem, what is an appropriate domain for h(t)?
ht? Explain your reasoning.
≤t≤
≤t≤ ; an appropriate domain is all times from the launch to when the watermelon hits the ground or seconds to seconds.
Listen to the complete question
Part B
Fill in the blank question.b. Use the graph of h(t)
ht to find the maximum height of the watermelon. When does the watermelon reach the maximum height? Explain your reasoning.
feet at seconds; the graph of h(t)
ht has a maximum at (, ), which represents the time at which the watermelon reaches it maximum height.
the car that will tow the trailer is restricted to pull a mass of not more than 500kg.The mass of each canned fish is 440g and the mass of each empty box is 27g. The school then decided to buy only 15 boxes of canned fish needed for a month. Determine the total mass in kg of each box containing 39 canned fish
