Choose the equation of a circle with radius 6 and center (2, -3).
Rufina [12.5K]

Answer:  (x-2)^2 + (y+3)^2 = 36\\\\

Work Shown:

(x-h)^2 + (y-k)^2 = r^2\\\\(x-2)^2 + (y-(-3))^2 = 6^2\\\\(x-2)^2 + (y+3)^2 = 36\\\\

Note that (h,k) = (2,-3) is the center and r = 6 is the radius. The last line is not expanded out using the FOIL rule because its common practice to leave it in (x-h)^2 + (y-k)^2 = r^2\\\\ form. This form allows the reader to quickly determine the center and radius (rather than have to do a lot of algebraic steps before hand).

Which expression uses the associative property to make it easier to evaluate? (50points)
Naily [24]

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

Step-by-step explanation:

Given expression is:

8.(\frac{1}{4}.\frac{3}{5})

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

a.(b.c) = (a.b).c

So applying the associative property on given expression

8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}

Hence,

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}
