Answer:
The value of x = 4 when the value of y = 12
Step-by-step explanation:
∵ y α x ⇒ it is direct variation
- It means y increase when x increase
∴ y = kx ⇒ where k is a constant
- To find the value of k we will substitute the values of x
and y in the equation above
- If y = 6 when x = 2
∴ 6 = k(2) ⇒ divide two sides by 2
∴ k = 3
∴ y = 3x ⇒ equation of variation
- To find the value of x when y = 12
- Substitute the value of y in the equation of variation
∴ 12 = 3x ⇒ divide both sides by 3
∴ x = 4
* The value of x = 4 when the value of y = 12
Answer:
Yes!
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
g(n) varies inversely with n.
This can be expressed alternatively as \[g(n) = \frac{k}{n}\] where k is a constant value.
Given that when n = 3, g(n) = 8.
This implies, \[8 = \frac{k}{3}\]
Simplifying the equation to solve for k, k = 8 * 3 = 24
Now when g(n) = 6, \[g(n) = \frac{k}{n}\]
\[6 = \frac{24}{n}\]
Calculating the value of n, \[n = \frac{24}{6}\] = 4
So the required value of n is 4.
T=PV/Rn you just divide both sides by Rn
