For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.

Use the information below for Part A, Part B, and Part C.
Simple interest varies jointly with principal and time. Tim deposited $1,500 into an account and left it for 6 years. He earned $450 interest.

Part A: Write the general formula. Be sure to define your variables.

Part B: Find the constant of variation and write the explicit formula.

Part C: How much interest would Tim have earned if he had deposited $4,500 into the account and left it for 12 years?

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
