Any repeated fraction is written as the number devided by nine(s).
for example
0.1111... =1/9
0.23232323... = 23/99

so the given number= -2 -7/9 = -25/9

butalik [34]

The length of the diameter, in meters, of the circular area that gets watered by the sprinkler for this condition is given by: Option B: 8 m

<h3>What is the equation of the circle of radius r units, centered at (x,y) ?</h3>

If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:

$(x-h)^2 + (y-k)^2 = r^2$

For this case, the equation of the circle that models tha circular area considered is:

$(x-9)^2 + (y+11)^2=16$

Writing this in standard form and comparing it with the standard equation, we get:

$(x-9)^2 + (y+11)^2=16\\(x-9)^2 + (y - (-11) )^2 = 4^2$ (didn't took (-4)² = 16 since radius cannot be negative).

Thus, we get center's coordinate as (9,-11) and radius of 4

The diameter of that circular area = twice of radius of the circle which models it = 2 × 4 = 8 meters.

Thus, the length of the diameter, in meters, of the circular area that gets watered by the sprinkler for this condition is given by: Option B: 8 m

Determine if f(x, y) = 10 − x^2 − y^2

Eva8 [605]

Answer:

Step-by-step explanation:

f(x,y)=10-x^2-y^2

To find derivative of z w.r.t. x is treat any other variable as a constant.

dz/dx=0-2x-0

dz/dx=-2x

Evaluating this at (7,-3) gives us dz/dx=-2(7)=-14.

Since this result is negative, it mrans as x increases z decreases.

f(x,y)=10-x^2-y^2

To find derivative of z w.r.t. y is treat any other variable as a constant.

dz/dx=0-0-2y

dz/dx=-2y

Evaluating this at (7,-3) gives us dz/dy=-2(-3)=6.

Since this result is positive it mrans as y increases z decreases.
