Can i please have help with number 6

Allisa [31]

Length of the diameter = sqrt ( (-12- (-8)^2) +(2-0)^2) )
= sqrt (16 + 4) = sqrt20
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5

Center of the circle = coordinates of the midpoint of the diameter =

-8-12/2 , 2-0 / 2 = (-10, 1)

(x - a)^2 + (y - b)^2 = r^2 is general form of a circle so here the circle is:_

(x + 10)^2 + (y - 1)^2 = 5 Answer

Its B

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.

julia-pushkina [17]

Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:

c(p) = 0.42p

Where: c(p) = total cost of sugar bought
p = pounds of sugar

c(p) is a function of p, because c(p) depends on p.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto

ruslelena [56]

X(u, v) = (2(v - c) / (d - c) + 1)cos(pi * (u - a) / (2b - 2a))
y(u, v) = (2(v - c) / (d - c) + 1)sin(pi * (u - a) / (2b - 2a))

As v ranges from c to d, 2(v - c) / (d - c) + 1 will range from 1 to 3, which is the perfect range for the radius. As u ranges from a to b, pi * (u - a) / (2b - 2a) will range from 0 to pi/2, which is the perfect range for the angle. So, this maps the rectangle to R.
