Answer:
x =
Step-by-step explanation:
Given a quadratic in standard form, ax² + bx + c : a ≠ 0
Then the axis of symmetry is a vertical line with equation x = h
where h is the x- coordinate of the vertex.
The x- coordinate of the vertex is
= -
f(x) = 5x² - 3x + 5 ← is in standard form
with a = 5 and b = - 3, thus
= - =
Thus the equation of the axis of symmetry is x =
Answer: 60
Step-by-step explanation:
Area = ½base × height
600 = ½b × 20
600/20 = ½b
Base = 30 × 2
The value of x is 4

Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
The answer would be 79.64
I circled the formula for the area of a sector.
