Explanation

Given f(t) = 1/t and g(t) = t³

To find gof(t), substitute f(t) into g(t):

gof(t) = g(f(t))

= g(1/t)

= (1/t)³

= 1/t³

Explanation

The prefix "kilo-" in the metric system means 1000 times the base unit.

Explanation

The function y = x + 100 is in the slope-intercept form y = mx + c, where:

m = 1 (slope)

c = 100 (y-intercept)

This confirms that the graph of the function is a straight line.

Explanation

At 170°C, ethanol undergoes acid-catalyzed dehydration to form ethene (C₂H₄).

Concentrated H₂SO₄ acts as a dehydrating agent, removing water from ethanol.
