Answer:
Equation is 7x^2 – 5x + 2
comparing with a,b and c
a = 7
b= –5
c = 2
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Sin55° = x/37 ⇒x = 37 * sin55° = 37 * 0.8192 ≈ 30.3
Step-by-step explanation:
You posted no answer choices, but a parallel oline has the same slope, so it is in the form
y = 1/5x + b
But b cannot be -1
