Answer: 25
Step-by-step explanation: (x-a)² = x² - 2ax + a²
From x² - 10x + k we deduce that 10x = 2·5x and a = 5
Then k = 5²2
Answer:
9.899495
Step-by-step explanation:
=(0−(−7))2+(−6−1)2−−−−−−−−−−−−−−−−−−−√
d=(7)2+(−7)2−−−−−−−−−−√
d=49+49−−−−−−√
d=9–√8
d=9.899495
The answer is B. The data is similar throughout the line.
-2.8 • -2.8 • -2.8 • -2.8 • -2.8 • -2.8
=481.890
Answer:
a) If c=3662 then q=228 and r=14.
b) If c=-3662, then q=-229 and r=2
Step-by-step explanation:
a) Observe that 229*16=3664, since r must be in the interval [0,16), then 229 doesn't work, but 228*16=3648 and 3662-3648=14.
Then 3662=228*16+14.
b) Observe that -228*16=-3648 and -3648-14=-3662, but r= must be positive. Then -228 doesn't work.
But observe that -229*16=-3664 and -3664+2=-3662. So -3662=-229*16+2
