Replace the variable r with 10 in the expression. p(10)+p Replace the variable p with 200 in the expression. (200)(10)+(200) Divide 200 by 10 to get 20. This will be the Dividend for the year. (20)+200 Add 200 to 20 to get 220. 220.00 Problem 2 p=5670 r=3.5 n=1 p(1+r)1 Reorder the polynomial 1+r alphabetically from left to right‚ starting with the highest order term. p(r+1) Multiply p by each term inside the parentheses. pr+p Replace the variable r with 3.5 in

Aim To investigate how parachutes work and whether size matters to performance. Background According to Agee (2010)‚ “As a skydiver is falling‚ the force of gravity is pulling them towards the earth… The parachute slows the skydiver down because it causes air resistance or drag. The air pushes the parachute back up‚ and creates a force opposite to the force of gravity‚ slowing the skydiver down.” Question We wanted to find out how the size of a parachute would affect its descent as we felt slowing

that is already known and not likely to change. It is always important to have a stable variable in any experiment you do. This also helps with overlooking hidden variables so you can compare how the organisms in the control behaved differently from those in the experimental situation. The purpose of having multiple variables is to compare the difference between the outcomes with each of the different variables. It is important to have large number of organisms so there is more of a population. Watching

This is a lab report is on the evolution of finches on Darwin Island and Wallace Island. I wanted to experiment with certain variables to see how the birds on these islands would be affected. By examining small populations of finches on these islands‚ I would like to see the outcome of beak size and population as the finches on the island evolve with different controlled environments. The environment on the islands can be changed by island size‚ precipitation‚ and diet. What will happen to the

rame Theoretical Framework Of The Study This section‚ deals with the different variables: independent variable (input)‚ dependent variable (output) and intervening variable (process) of the proposed study and to show their relationship with one another. It includes paradigm or the model representing the framework of the study theoretically. The paradigm would show the difference between the existing and the proposed system Input-Process-Output diagram. Existing System
