2 is C but I dunno about 1
Answer:
yes it is arithmetic because:
28 - 10= 18
18 - 10= 8
8 - 10= -2
it keeps decreasing by the same number (10). Therefore, it is arithmetic.
I believe the expression would be:
x+2
For example, if you have the odd number 3 as x, 3+2 would be 5, the next odd number.
Hope this helped!! xx
Answer:
i) The variation <em> equation H = k L</em>
<em>ii) The value of H = 20</em>
<em>iii) C) H = k L</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that H varies directly as L </em>
<em> H ∝ L</em>
<em> H = k L</em>
<em>Given that H =30 and L = 60</em>
<em> ⇒ 30 = k (60)</em>
<em> </em><em></em>
<u><em>Step(ii):-</em></u>
Given that L = 40
The variation of the equation = H = k L ...(i)
put L = 40 in equation (i)
