Answer:

The center is (-10,10) and the radius is 4sqrt(3)

Step-by-step explanation:

(x + 10)^2 + (y - 10)^2 = 48

We can write the equation of a circle as

(x -h)^2 + (y - k)^2 = r^2 where (h,k) is the center and r is the radius

(x- -10)^2 + (y - 10)^2 = (sqrt(16*3) )^2

(x- -10)^2 + (y - 10)^2 = (4sqrt(3)) ^2

The center is (-10,10) and the radius is 4sqrt(3)

Answer:

$y=5 \ \ \ x x_o + 1.9s$

Step-by-step explanation:

This situation can be considered as a piecewise function. First, you take xo as the time in which the drone goes upward. Before this time the height of the drone is constant with a value of 5 m. Next, you take into account that during 1.9 s after xo the drone accelerates. Finally, the drone flies again with a constant height of 5.9m. Hence, this function has three parts:

For the first part you have:

y = 5 for x < xo

For the second part you first calculate vertical speed (which means the slope of the linear function) by using the following kinematic equation:

$y=vx\\\\v=\frac{y-y_o}{x}=\frac{5.9m-5.0m}{1.9s}=0.47m/s$
