Answer:
Step-by-step explanation:
hello :
x2+y2+16y−30x=0 means : (x²-30x)+(y²+16y) =0
(x²-30x+15²)-15²+(y²+16y+8²) -8²=0
(x-15)²-225+(y+8)²-64=0
(x-15)²+(y+8)²=289=17²......standard form when the center is (15,- 8)
and radius 17
A cube represents 1,000 and a flat 100. You can solve this problem by saying the number out loud. "One thousand, two hundred." That means that you need one thousand (cube) and two hundreds (flat). So one cube and two flats will be 1,000+100+100, which equals 1,200.
Answer:
To the nearest hundredth, 2.85
To the nearest hundred, zero
Step-by-step explanation:
F(x) = 2(x+6). If f(x) = 22, that means replace f(x) with 22
22 = 2(x+6) or
22 = 2x + 12 . Now solve this equation with the variable x:
2x = 22 - 12
2x = 10
x = 5 (Answer B)
The cost of the premium - $16,000 (40 x $400)
The cost of coverage - $150,000
The cost of the coverage is more
