The answer to your question is: letter d
Step-by-step explanation:
Convert 75° to radians
360° ----------------- 2π rad Rule of three
75° ----------------- x
x = (75 x 2π rad ) / 360
x = 150π rad / 360
x = 15π rad / 36 Simplify
x = 5 π rad / 12
It will take 9 hours because 3 times 9 is 27
Hello,
x²-16x+y²+6y+53=0
==>x²-2*8*x+8² + y²+2*3*y+3²+53-64-9=0
==>(x-8)²+(y+3)²=20
Center is (8,-3) and radius =√20
