Answer:
(a) 0.018 dm^3
(b) 20 x 10^15 ml^3
Step-by-step explanation:
a) 18 cm^3 to dm^3
1 cm = 0.1 dm
So,
1 cm^3 = 0.001 dm^3
So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3
b) 20 hl^3 to ml^3
1 hl = 100000 ml
So, 1 hl^3 = 10^15 ml^3
So,
20 hl^3 = 20 x 10^15 ml^3.
We are given f(x) =3x and g(x) =2x
Now we have to find (g*f)(x).
so (g*f)(x) means we multiply f(x) and g(x).
So multiplying 3x and 2x,
3x * 2x = 6x²
So (g*f)(x) =6x²
<span>The top item on a list of your life goals should be B. a goal that's most important to you. You shouldn't care much for what other people want from you - if you know what you want and need, you should make that your priority and try to achieve your life goals. It doesnt matter whether you can manage that financially, or whether it's going to be easy - if you really want it, you are going to try your best in order to achieve it. </span>
