Using the slope concept, it is found that the angle of the swimmer's resultant vector is of 71.83º.
<h3>What is a slope?</h3>- The slope is given by the <u>vertical change divided by the horizontal change.</u>
- It's also the tangent of the <u>angle of depression.</u>
In this problem:
- The person swims 6.4 meters per second north, hence the vertical change is of 6.4.
- The person is being pushed by a current moving west at 2.1 meters per second, hence the horizontal change is 2.1.
Then, considering that the slope is the tangent of the angle of depression , which is also the angle of the swimmer's resultant vector, we have that:
Using a trigonometric calculator:
The angle of the swimmer's resultant vector is of 71.83º.

Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : r
so replacing the number of the radius into the equation, it would look like:
r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
