## If r varies directly as s and inversely as the

**Ask: **If r varies directly as s and inversely as the square of u, and r=4 when s=18 and u=3, find r when u = 3 and s = 27

## ANSWER

[tex] \ [/tex]

### If r varies directly as s and inversely as the square of u, and r=4 when s=18 and u=3, find r when u = 3 and s = 27.

[tex] \ r = frac{ks}{ {u}^{2} } \ \ [/tex]

Evaluate the values

[tex] \ 4 = frac{k(18)}{ {3}^{2} } \ \ [/tex]

Square 3

[tex] \ 4 = frac{k(18)}{9} \ \ [/tex]

Multiply 9 to both sides

[tex] \ (9)(4) = frac{k(18)}{9} (9) \ \ [/tex]

Cancel both 9 from the right side

[tex] \ (9)(4) = frac{k(18)}{ cancel9} ( cancel9) \ \ [/tex]

Multiply 9 to 4

[tex] \ 36 = k(18) \ \ [/tex]

Divide 18 to both sides

[tex] \ frac{36}{18} = frac{k(18)}{18} \ \ [/tex]

Cancel both 18 from the right side

[tex] \ frac{36}{18} = frac{k( cancel{18})}{ cancel{18}} \ \ [/tex]

Divide

[tex] \ large boxed{ bold{k = 2}} \ \ [/tex]

### Find r when u = 3 and s = 27. Use the constant of variation of the first problem.

[tex] \ r = frac{ks}{ {u}^{2} } \ \ [/tex]

Evaluate values

[tex] \ r = frac{(2)(27)}{ {3}^{2} } \ \ [/tex]

Square 3

[tex] \ r = frac{(2)(27)}{9} \ \ [/tex]

Multiply 27 to 2

[tex] \ r = frac{54}{9} \ \ [/tex]

Divide

[tex] \ huge green{ boxed{ bold{r = 6}}} \ \ \ [/tex]

## r when u = 3 and s = 27

**Ask: **r when u = 3 and s = 27

**Answer:**

The value of r is 9.

Step-by-step explanation:

Mathematical Equation:

r=frac{sk}{u}r=

## if r varies direclty as s and inversely as the

**Ask: **if r varies direclty as s and inversely as the square of u, and r=2 when s=18 and u=2, find r when u=3 and s=27

**Answer:**

**Step-by-step explanation:**

[tex]r= frac{ks}{u^{2} }[/tex]

[tex]2=frac{k(18)}{2^{2} } \2=frac{18k}{4 } \k=frac{4}{9 }[/tex]

[tex]r= frac{frac{4}{9} (27)}{3^{2} }\r=frac{4}{3}[/tex]

## r varies directly as s and ineversely as u, and

**Ask: **r varies directly as s and ineversely as u, and r=30 when s=18 and u=3, find r when u=9 and s=27

[tex]qquadlargebold{JOINT: VARIATION}[/tex]

[tex]textsf{r varies directly as s and inversely as u}[/tex]

[tex]bold{EQUATION:}[/tex] [tex]boxed{tt r=frac{ks}{u}}[/tex]

where k is the constant of the variation

[tex]bold{GIVEN:}[/tex]

- r = 30 when s =18 and u=3

[tex]bold{UNKNOWN:}[/tex]

- constant of the variation k
- r when u = 9 and s = 27

[tex]bold{SOLUTION:}[/tex]

First, we will find the value of k

[tex] begin{array}{c} large tt r = frac{ks}{u} \ \ large tt 30= frac{k(18)}{(3)} \ \ large tt 30 = frac{18k}{3} \ \ large tt 30 = 6k \ \ large tt frac{30}{6} = frac{6k}{6} \ \ large boxed{tt k = 5} end{array}[/tex]

Then, we will substitute the value of k to find r when u = 9 and s =27

[tex] begin{array}{l} large tt r = frac{ks}{u} \ \ large tt r = frac{(5)(27)}{9} \ \ large tt r = frac{135}{9} \ \ large red{ boxed{ tt r = 15}} end{array}[/tex]
