Answer:
Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :
Hence, the value of r² is equal to 
.
n=5
Proof:
(n-1)(n+3)=32 Now, substitute n with 5
(5-1)(5+3)
(4)(8)
=32
For roots, r1 and r2 the factors are
(x-r1)(x-r2)
roots are 6 and -5
(x-6)(x+5)
and a point is (-1,3)
(x,y)
y=a(x-6)(x+5)
3=a(-1-6)(-1+5)
B is the answer
Answer:
1/2, 6/10, 2/3, 3/4
Step-by-step explanation:
we can convert each fraction to a decimal to compare:
2/3 = 0.666666 repeating
1/2 = 0.50
3/4 = 0.75
6/10 = 0.60
least to greatest:
1/2, 6/10, 2/3, 3/4
(21-2n)/2
