Hello :
<span>x2 + y2 + z2 + 4x − 6y − 6z = −6
(x²+4x) +(y² - 6y) +( z² -6z) = -6
((x² +4x +4) -4 ) + ((y² - 6y +9) - 9 ) + ((z² - 6z+9) -9 ) = - 6
(x+2)² + (y - 3)² + ( z - 3)² = 4²...( </span><span>standard form )</span>
Answer:
Step-by-step explanation:
AD = 4
AC = 11
DC = 11 - 4 = 7
First, find BD using the right triangle altitude theorem:
Plug in the values
Use pythagorean theorem to find x:
x² = AD² + BD²
Plug in the values
Take the square root of both sides
The answer is: 1.568764162
Total = Principal * (1 + rate /52) ^ 52*years
Total = 10,250 * ( <span>1.0017307692) ^ 364
