Sally's parents deposited $15,000 into a college savings account on her third birthday. The account had an interest rate of 9.6%
compounded annually. They were hoping that the money would double twice by the time she was 18 years old. Using the rule of
7.

Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.
Yes, the $15,000 will double in 7.5 years and be four times as much in 15 years.
No, the $15,000 will only double once in 15 years, not double twice.
No, it will take 30 years for the $15,000 to double twice.

Data was collected on myrtle beach for 11 consecutive days. each day the temperature and number of visitors was noted. the scatter plot below represents this data. how many people visited the beach when the temperature was 84 degrees?

Acertain population of bacteria demonstrates exponential growth doubles in size every 4 days. how long will it take the population to triple in size?

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
