2 x 10 to the 3rd power is
2x10^3
The answer is k= -6 I just don’t know how to explain it to you!
Answer:
x=
, -![\sqrt[12]{-66}](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B-66%7D)
Step-by-step explanation:
Answer:
<em>D = 41</em>
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
12o + 7a = 5.36
8o + 5a = 3.68
a ≈ 0.32
o ≈ 0.26
