Urgent answer please <br> Ax+ay+xa+ya
marin [14]

Answer:

Possible derivation:

d/dx(a x + a y(x) + x a + y(x) a)

Rewrite the expression: a x + a y(x) + x a + y(x) a = 2 a x + 2 a y(x):

= d/dx(2 a x + 2 a y(x))

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + 2 a (d/dx(y(x)))

The derivative of x is 1:

= 2 a (d/dx(y(x))) + 1 2 a

Using the chain rule, d/dx(y(x)) = (dy(u))/(du) (du)/(dx), where u = x and d/(du)(y(u)) = y'(u):

= 2 a + d/dx(x) y'(x) 2 a

The derivative of x is 1:

= 2 a + 1 2 a y'(x)

Simplify the expression:

= 2 a + 2 a y'(x)

Simplify the expression:

Answer:  = 2 a

The equation (x – 5)^2 + (y – 7)^2 = 81 models the position and range of a cellular phone tower. What is the range of the tower?
LiRa [457]

Answer:

In interval form range is [-2,16]

Step-by-step explanation:

Here we can see that given equation is circle

whose center is (5,7 ) and radius is 8 ,

Range of the circle is actually values of y it changes from

if (h,k) is the center and r is the radius of circle then range is given by

                     k-r     ≤y ≤ k+r

here in the question k = 7 and r =9

therefore  range is

       7-9     ≤y ≤ 7+9

          -2  ≤y ≤ 16

In interval form [-2,16]
