A scientist wants to estimate the number of lions living in a region. On Thursday, he locates and tags some lions. I
On Friday he returns and locates 10 less lions than he had on Thursday.
He notices that 4 of the lions are tagged
The scientist works out an estimate for the total number of lions living in the
region.
He notices that the number of lions that he had caught on Thursday, was a
fifth of the total number of lions.
How many lions live in the region?

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 > ?
