What is the equation of a circle with center (-2,3) and radius 4? A. (x + 2)2 + (-3)2 = 4
+
O B. (x-2)+ (y + 3) = 16
O c. (x+2)2 +(y - 3)2 =
= 16
O D. (x+2)2 – (y - 3)2 = 16

yes

step-by-step explanation:

ok then what happened.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
