Answer:
Step-by-step explanation:
Given
Geometry Progression
Required
Calculate the second term
First, we need to write out the formula to calculate the nth term of a GP
For first term: Tn = 500 and n = 1
For fought term: Tn = 32 and n = 4
Substitute 500 for a
Make r^3 the subject
Take cube roots
Using:
and
<em>Hence, the second term is 200</em>
Answe5:5/9
Step-by-step explanation:
The time(h), would be the independent variable and the temperature(C) would be the dependent variable.

Answer:
y = 4x + 48
Step-by-step explanation:
Original equation:
y = 1/4x -12
Switch 'x' and 'y' to solve for the inverse:
x = 1/4y - 12
Add 12 to both sides:
x + 12 = 1/4y - 12 + 12
x + 12 = 1/4y
Multiply both sides by 4:
4(x+12) = y
4x + 48 = y
The inverse is y = 4x + 48
