Find the quadratic function that has roots of -9 and 3 and a vertex of (-3,-36)

natita [175]

Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99

Can someone please help me with this?

Answer:

e = 29.0 will be the answer.

Step-by-step explanation:

Use the sine rule in the given triangle,

$\frac{EF}{\text{sin}(\angle D)}=\frac{DE}{\text{sin}(\angle F)}=\frac{DF}{\text{sin}(\angle E)}$

$\frac{d}{\text{sin}(35)}=\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$d=\frac{16\times \text{sin}(35)}{\text{sin}(30)}$

d = 18.35

$\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$e=\frac{16\times \text{sin}(115)}{\text{sin}(30)}$

e = 29.002

e ≈ 29.0

Therefore, e = 29.0 will be the answer.
