Given that f(x) x2 + 3x 10 and g(x) = x – 2, find f (x) · g(x) and

lakkis [162]

Answer:

x^3 + x^2 + 4x - 20.

Step-by-step explanation:

I have assumed there is a + between the 3x and the 10.

f(x) * g(x)

= (x^2 + 3x + 10)(x - 2)

= x^3 + 3x^2 + 10x - 2x^2 - 6x - 20

= x^3 + x^2 + 4x - 20.

Find the missing dimension of the cylinder. Round your answer to the nearest hundredth.

ivann1987 [24]

Answer:

The missing dimension, radius = 6.00 m

Step-by-step explanation:

We are given the following things:

Height of cylinder, $h$ = 15 m

Radius of cylinder, $r = z$ m (Labelled as $z$ )

Volume of cylinder, $V = 1696.5\ m^{3}$

Please refer to the image attached for the dimensions of cylinder as given.

We know that the volume of a cylinder can be given as:

$V = \pi r^{2} h$

Where $r$ is the radius of cylinder

$h$ is the height of cylinder

Putting the values of $V, r \text{ and } h$ :

$1696.5 = \pi z^{2} \times 15\\\Rightarrow z^{2} = 36.01\\\Rightarrow z = 6.00\ m$

Hence, The missing dimension, radius = 6.00 m
