There are 18 adult shirts sold because 12×10 is 120 and 15×18 equals 270 and 270+120 equals 390
Y = mx + b
y - b = mx
(y - b) / x = m
so its : m = (y - b) / x.....or m = (y/x) - (b/x)

Answer:
A. 
Step-by-step explanation:
We have been given a diagram. We are asked to find the measure of angle ABC.
First of all, we will find measure of major arc AC by subtracting 146 from 360 degrees.


Now, we will use tangent-tangent angle theorem to solve for ABC.
Tangent-Tangent angle theorem states that angle formed by two tangents outside a circle is half the difference of intercepted arcs.



Therefore, the measure of angle ABC is 34 degrees and option A is the correct choice.
Answer:
Alice reaches 11 metres below the centre as lowest height.
Step-by-step explanation:
Cosine is a bounded function between -1 and 1, so that the lowest height that Alice achieves in Ferris wheel is:

Where:
- Time, measured in seconds.
- Height with respect to centre, measured in metres.
If
, then:


Alice reaches 11 metres below the centre as lowest height.
