Answer:
<h2>a) center (2, -3)</h2><h2>b) radius r = 3</h2><h2>c) in the attachment</h2>
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have:
a) center (2, -3)
b) radius r = 3
c) in the attachment
Multiply the first coefficient (3) and the last term (2) to get 3*2 = 6
We need to find two numbers that
a) multiply to 6
AND
b) add to -5 (middle coefficient)
Such two numbers are -3 and -2
-3 times -2 = 6
-3 plus -2 = -5
So we can break up the -5x into -3x-2x and then factor by grouping
--------------
3x^2-5x+2
3x^2-3x-2x+2
(3x^2-3x)+(-2x+2)
3x(x-1)+(-2x+2)
3x(x-1)-2(x-1)
(3x-2)(x-1)
So the two factors are (3x-2) and (x-1)
The answers are A and C
Step-by-step explanation:
for x^a/x^b = x^(a-b)...eqn 1
thus for 5^6/5^2 = a^b,
if a = 5, following eqn 1...
then b = 6-2 = 4
