he graph shows the amount of a medicine m, in milligrams, remaining in a patients body h hours after receiving an injection. The amount of the medicine decreases exponentially. 1. By what factor did the medicine decrease in the first hour and a half? Explain how you know. 2. By what factor did the medicine decrease in the first half-hour? What about in the first hour? Explain how you know. 3. Write an equation relating m, the number of milligram of the drug in the patient's body, and h, the number of hours since the injection.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
