True or false: the order of the general steps in building math models is: step 1. define the problem and identify the parameters step 2. simplify the problem statement step 3. determine the data needed to answer the question step 4. interpret and revise the model step 5. gather the appropriate data step 6. analyze the data step 7. draw reasonable conclusions true false

What is the total surface area of this square pyramid?

If the simple annual interest rate on a loan is 6, what is the interest rate in percentage per month?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
