A circle has it center at (-2,-3) and a radius of three units what is the equation of the circle

Step-by-step explanation:

The equation for a circle in standard form is , where h and k are the coordinates of the center.  Our center has an h value of -2 and a k value of -3 with an r value of 3.  Fitting those values into our standard form of a circle we have .  Subtracting a negative is the same as adding, and squaring the right side gives us 9, so the equation is .  Third choice from the top.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
