What is the value of k when 4x squared plus kx plus 9 equals 0?
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
How do you write algebraic expression in words for k plus 2.5?
k added to 2.5
What is 5r plus 20 equals 40?
It is a linear equation in the variable r.
What are the possible values of k in the quadratic equation x squared plus 5kx plus 2k equals 0 which has equal real roots?
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
What is the center of the circle given by the equation ((x plus 5)2 (y-8)21?
The equation you provided appears to be incorrectly formatted. However, if you meant to write the standard form of a circle's equation, which is ((x - h)^2 + (y - k)^2 = r^2), then the center of the circle is given by the point ((h, k)). For the specific equation you intended, please clarify the format, and I can help identify the center accordingly.
Balanced equation for the production of potassium chloride?
2K(s) + Cl2(g) → 2KCl(s)
How do you balance BrCl --- Cl2 plus Br2?
Ca + Cl2 ----> CaCl Step 1) Ca + Cl2 ----> 2 CaCl There are 2 Cl's on the reaction side so you need 2 on the Product side Step 2) 2Ca + Cl2 ----> 2 CaCl There are now 2 Ca on the product side and you need 2 on the reactant side Voila!
What is the chemical equation of potassium metal and chlorine gas combine to form potassium chloride?
The chemical equation is:2 K + Cl2 = 2 KCl
Solve the equation k plus 3.4 equals 9?
k equals 5.6
Is K Br2 2KBr balanced?
Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
Write the point-slope equation of the line that goes through 5 3 with a slope of -12?
A line in the X-Y plane follows an equation y = (slope X x) plus a constant k. In this instances, 5 = [(-12)(3)] + k, or k = 5 + 36 = 41. Therefore, the equation is: y = -12x + 41.
How do you balance this equation K plus Br2--- KBR?
2 K + Br2 -> 2 Kbr
How do you balance the equation K plus H2O yields H2 plus KOH?
Balanced :2 K + 2 H2O ----> 2 KOH + H2
What is the value of k when 4x squared plus kx plus 9 equals 0?
