51 The velocity V of the blood flow of a skier is modeled by V = 375(R² – r²) where R is the radius of the blood vessel, r is the distance of the blood flow from the center of the vessel and is a constant. Suppose the skier's blood vessel has radius R =0.08 mm and that cold weather is causing the vessel to contract at a rate of dR/dt = -0.01 mm per minute. How fast is the velocity of the blood changing? %3D 6. Find the absolute maximum and absolute minimum values of the function f (x) = -
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.
