The approximate area that is within range of the motion sensor is 4975 square meters

<h3>How to determine the area of the range?</h3>

The figure is not given, however the area of the range can be calculated without the figure.

The given parameters are:

Angle, ⊕ = 135°

Radius, r = 65 meters

The area of the range is calculated using the following sector area

A = \frac{\theta}{360} * \pi r^2

This gives

A = \frac{135}{360} * 3.14 *  65^2

Evaluate

A = 4974.9375

Approximate

A = 4975

Hence, the approximate area that is within range of the motion sensor is 4975 square meters

What is the equation of the function that is graphed as line a?
Andrei [34K]

Answer:

B

Step-by-step explanation:

We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is \frac{1}{3}, meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.
