Which equation is a radical equation.

OlgaM077 [116]

Hi there! :)

A radical equation is an equation in which a variable (ex. x, y, a, v) is under a radical sign. The only equation that has a variable under a radical (x) is the second option. There is an x next to the 2 under the radical.

I hope this helps, DM me if you have anymore questions. :)

A motion sensor has a range of 65 meters as shown. The ultrasonic waves sweeping out from the sensor span an angle of 135°.

VMariaS [17]

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 result of adding these two equations? \begin{aligned} 2x+3y &= -5 \\\\ 5x-y &= -12 \end{aligned} 2x+3y 5x−y

EleoNora [17]

Answer:

$7x+2y = -17$

Step-by-step explanation:

We have the following equations:

$2x+3y = -5$

$5x-y = -12$

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

$(2x+5x)+(3y-y) = -5-12$

$7x+2y = -17$

I hope it helps you!
