Answer:
<h2>y = 2</h2>Step-by-step explanation:
To find the value of y when x = 8 we must first find the relationship between the two variables.
The statement
y varies directly with variable x is written as
y = kx
where k is the constant of proportionality
when
x = 12
y = 3
Substitute the values into the above formula and solve for k
That's
3 = 12k
Divide both sides by 12
So the formula for the variation is
when
x = 8
we have the final answer as
<h3>y = 2</h3>Hope this helps you
Answer:
5859375
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
=
where r is the common ratio and the first term
here r = =
=
= 5 and
= 3, hence
= 3 ×
