Pythagorean Theorm Unit? I got you!
It would be C, about 63.07
So, teh exact value is sqrt( 19^2 - 8^2 ) = sqrt( 361-64) = sqrt(297).
There's people who can calculate this mentally, but I can't. Approximate by known squares: 15^2 = 225, 16^2 = 256, 17^2= 289, 18^2=324,
So, 18.
Answer:
y = |x-3| + |x+2| - |x-5|, if x <-2
y = |x-3| + |x+2| - |x-5|
y = -x-3 - x+2 + x-5
y = -x -6
Answer:
-49
Step-by-step explanation:
multiply 7 with 7 then i with i and lastly multiply the result numbers
7i × 7i ➡ 7 × 7 = 49
i × i = i^2
49 × i^2 = 49i^2
i^2 = -1 ➡ 49 × (-1) = -49
I think that can help for now
