Answer:

first option

Step-by-step explanation:

To obtain ( f ￮ g)(x) substitute x = g(x) into f(x) , that is

f( $\frac{1}{2x}$ )

= $\frac{2}{\frac{1}{2x}+3 }$ ( multiply numerator/ denominator by 2x to clear the fraction

= $\frac{2(2x)}{2x(\frac{1}{2x}+3) }$

= $\frac{4x}{1+6x}$

Answer:

Option (4).

Step-by-step explanation:

Outer diameter of the hollow metallic ball = 10 centimeters

Outer radius of this ball = $\frac{10}{2}$ = 5 cm

Volume of the outer ball $V_{1}$ = $\frac{4}{3}\pi (r)^3$

= $\frac{4}{3}\pi (5)^3$

Inner radius of the hollow metallic ball = (5 - 1) = 4 cm

Volume of the inner hollow ball $V_{2}$ = $\frac{4}{3}\pi (4)^3$

Volume of the metal used in the metallic ball = $V_{1}-V_{2}$

= $\frac{4}{3}\pi (5)^3-\frac{4}{3}\pi (4)^{3}$

= $\frac{4}{3}\pi [(5)^3-(4)^3]$

Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.

A) Volume of a cube is found by multiplying its side by itself twice.

V = a³
V = 4³ = 4 * 4 * 4
V = 64 ft³

b) 1 cubic foot = 7.48 gallons of water.
total gallons of water = 64 ft³ x 7.48 gallons = 478.72 or 479 gallons rounded up to the nearest gallon.

Latrice is given an unknown substance and is asked to identify is based on his properties. She measures its mass as 239.6grams.

Answer:

density =8.87g/cm³

From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.

Step-by-step explanation:

This problem bothers on the density of substances

Given data

Mass m of substance = 239.6grams

length l=3cm

width b=3cm

height h=3cm

Volume of substance =l*b*h

=3*3*3=27cm³

We know that the density of the substance ρ=mass/volume

ρ= 239.6/27= 8.87g/cm³
