What is the axis of symmetry for f(x) = 2x2 − 4x + 5?
Romashka-Z-Leto [24]

Answer:

Axis of symmetry is

C) x = 1

Step-by-step explanation:

we are given equation as

2x^2 -4x+5

we can use axis of symmetry formula

Let's assume we are given quadratic equation as

y=ax^2+bx+c

Axis of symmetry is

x=-\frac{b}{2a}

now, we can compare both equations

and we get

a=2,b=-4

now, we can find axis of symmetry

x=-\frac{(-4)}{2\times 2}

x=-\frac{(-4)}{4}

x=1

A special liquid is held in a tank described as (x 2 + y 2 ) ≤ z ≤ 1 in a Cartesian coordinate system. Assume that the density o
vivado [14]

Since \rho=\dfrac mV (density = mass/volume), we can get the mass/weight of the liquid by integrating the density \rho(x,y,z) over the interior of the tank. This is done with the integral

\displaystyle\int_{-1}^1\int_{-\sqrt{1-x^2}}^{\sqrt{1-x^2}}\int_{x^2+y^2}^1(2-z^2)\,\mathrm dz\,\mathrm dy\,\mathrm dx

which is more readily computed in cylindrical coordinates as

\displaystyle\int_0^{2\pi}\int_0^1\int_{r^2}^1(2-z^2)r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=\boxed{\frac{3\pi}4}
