No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
For the slope of ln:
For the slope of mn:
- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.

They are inverse of logarithmic equations. The value of b to the nearest tenth is 0.1
<h3>Exponential equations</h3>They are inverse of logarithmic equations. Given the exponential function that modelled the penicillin concentration, in micrograms per milliliter as shown:
If the value of P(t) is 10, hence;
Take the ln of both sides
ln0.05 = 6/5 lnb
-2.995 = 1.2 ln b
lnb = -2.495
b = e^-2.495
b = 0.08
Hence the value of b to the nearest tenth is 0.1
