Answer:
vertex = (8, - 1 )
Step-by-step explanation:
Given a parabola in standard form, f(x) = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
f(x) = x² - 16x + 63 ← is in standard form
with a = 1 and b = - 16, thus
= -
= 8
Substitute x = 8 into f(x)
f(8) = 8² - 16(8) + 63 = 64 - 128 + 63 = - 1
vertex = (8, - 1 )
Answer:
Step-by-step explanation:
Given : sin θ = 3/5
To Find : value of cos θ and tan θ
Solution :
use the identity:
putting value of sin θ
