The answer to this is Complementary Angles.
The answer would be C. both plane A and B because it's on line s which lies on both planes.
Answer:
<em>3.9 kg</em>
Step-by-step explanation:
total mass = (number of nails) * (mass of one nail)
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 0.0052 kg
total mass = 3.9 kg
Answer:
Step-by-step explanation:
The coefficients of the quadratic x^2 + 7x + 3 are a = 1, b = 7 and c = 3.
The discriminant is b^2 - 4ac, or 49 - 4(1)(3), or 49-12, or 37.
Because the discriminant is positive, we know that this quadratic equation has two real, different solutions.
-7 ± √37
x = --------------- => x = (-7 + √37)/2 and x = (-7 - √37)/2
2
In words: This quadratic equation has two real, unequal solutions involving the radicand 37.
