Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
Solution:
<u>Note that:</u>
<u>Using the clue above, let's solve each problem.</u>
- 10 mL = 10/1,000 L = 0.01 L
- 1.2 L = 1.2 x 1,000 mL = 1,200 mL
- 3,500 mL = 3,500/1,000 L = 3.5 L
- 4 L = 4 x 1,000 mL = 4,000 mL
- 230 mL = 230/1,000 L = 0.23 L
- 6.21 L = 6.21 x 1,000 mL = 6,210 mL

Using translation concepts, the graph of f(x) = (x - 2)² + 3 is given at the end of the question.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In this problem, we have that the parent and the translated function are given, respectively, by:
The translations are as follows:
- Right two units, as x -> x - 2.
- Up 3 units, because f(x) = g(x) + 3.
Hence the graphs are given at the end of the answer, with the parent function in red and the translated function f(x) = (x - 2)² + 3 in green.

Answer:
i think probably x∉∅
Step-by-step explanation:
3x-7 = 3x+9
-7 = 9
so x∉∅
