On the early detection period of COVID-19, there were 557 people verified to have been infected by the virus. This rate of increase is modeled using the differential equation below, with N being the number of people, and t for the time elapsed (in days) since it was detected on January 22, 2020. dN = (37602 – 1002.42t + 14.6982t² – 0.0204t³)dt With the creation of the vaccines, the modeled equation shifted to the one below. The variable Nm is the number of people still infected due to mishandling of the vaccine, resulting to unavailability for some countries. dNm = (42023 – 1155.8t + 15.8388t² – 0.0228t³)dt Determine the number of people that can be saved by the vaccine if it is to be administered on March 8, 2021, on the assumption that no side-effects and complications will be triggered.
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.
