Find the equation of the axis of symmetry for this function F(x)= 5x^2 - 3x + 5
1 answer:
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:
Cost to rent one tank=226.08 Dollars
Step-by-step explanation:
Radius of the cylindrical tank=3 feet
Height of the tank= 2 feet
Cost to rent one tank= Volume of one tank * cost to rent one cubic feet of volume
Volume of the cylindrical tank:
=
As,
Putting the values in the formula:
Volume of the tank:
Cost to rent one cubic feet= 4 Dollars
Cost to rent 56.52 Cubic feet of one tank;
= 4*56.52
=226.08 Dollars
