Answer:
3 bars of soap and 2 toothbrushes.
Step-by-step explanation:
Yes, exponential or log I think! It is a function — use vertical line test
Answer:
The line passes (2, 5) and (4, 7) has slope:
S = (7 - 5)/(4 - 2) = 2/2 = 1
The line passes (1, 7) and (-4, 2) has slope:
S = (2 - 7)/(-4 - 4) = 5/-5 = -1
The multiplication of two slope is 1 x (-1) = -1
=> Two lines are perpendicular
Hope this helps!

Answer:
h ≈ 13.4
Step-by-step explanation:
Since the triangle is right we can use the sine ratio to find h
sin48° = 
= 
Multiply both sides by 18
18 × sin48° = h
⇒ h = 13.4 cm ( to 1 dec. place )
