Answer:
La raíz cuadrada de 721
Step-by-step explanation:
La Segunda Raíz o Raíz Cuadrada del número 721 es 26.8514431642
Esto se comprueba multiplicando 26.8514431642 por si mismo, debe arrojar como resultado 721
o en otro termino 721.9049245737
The Second Root or Square Root of the number 721 is 26.8514431642
This is proven by multiplying 26.8514431642 by itself, it must result in 721
or in another term 721.9049245737
X - 2y = 3
<span>4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(</span>3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2<span> - 15y - </span><span>10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- </span>√(33^2 - 4*6*33)<span>)/12
</span>y = (-33 +- √(297)<span>)/12
</span>so there are 2 solutions for y:
y1 = (-33 + √(297)<span>)/12
</span>y2 = (-33 - √(297)<span>)/12
</span>pick one and then substitute the y value in the first equation to find x
Answer: theres a answer key in the last slide & its 15 somehow...
Answer:
yes
Step-by-step explanation:
Use Pythagorean Theorem:
10² + 49.5² = 50.5² ??
100 + 2450.25 = 2550.25
