Answer:
D. Rx) = x2 - 4x + 10
Step-by-step explanation:
R(x)=(x-2)^2+6
R(x)=(x-2)^2+6
=(x-2)(x-2)+6
=x^2-2x-2x+4+6
=x^2-4x+10
R(x) = x^2 - 4x + 10
Option D is the answer
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because
is less than x, the new amount would be less than the original.
Divide 77.5 by 10 = 7.75
Since we divide by 10.2 (and not 10), we **subtract** 2% of 7.75, which is about 0.155 to give 7.595. (error=-0.04%)
You can also simplify a little by approximating 2% of 7.75 as 0.15 to give 7.6 as your estimate. (error=+0.026%)
exact value = 7.598...

so.. to get the x,y coordinates, or rectangular ones, get the cosine and sine of that angle, and multiply it times the "r"adius
I think the answer for this question is letter C: SAS
