Make use of the formulas that relate p and a to the focus and directrix. Fill in the values you know and solve for the remaing one(s).
Step-by-step explanation:
the equation of line is given by;
y-y1=m(x-x1)
Answer:
In early production, first calcium cyanamide was converted into dicyandiamide, which was heated above its melting temperature to produce melamine. Today most industrial manufacturers use urea in the following reaction to produce melamine: 6 (NH2)2CO → C3H6N6 + 6 NH3 + 3 CO.
(You forgot to provide the choices!?!)
A.) Cos Z = b/c
B.) Sin X= c/b
C.) Tan X = b/a
D.) Tan Z = a/b
B is the answer, Sin X = c/b is wong because Sin X= b/c ( sin = opposite/ hypotenuse)
Hope this helps.!
The formula for compounded interest in this type of equation is:
where A is the amount at the end of the time period, P is the principal amount you start with, R is the interest rate, N is the amount of compound periods, and T is the time allotted for the money to gain interest.
P = 5000, R = 3% or 0.03, N = monthly so 12, T = 2 years
Plug in our given information into the equation:
Let the calculator do the work here...
A ≈ 5308.785 which rounds to A ≈ 5308.79
Option A is your answer.
