f varies jointly as g, h, and j. One set of values is f=18, g=4, h=3, and j=5. Find f when g=5, h=12, and j=3.

IrinaK [193]

Answer:

$\boxed{60}$

Step-by-step explanation:

f ∝ ghj

Convert the proportion to an equality

f = kghj

Calculate the value of k

18 = k × 4 × 3 × 5

18 = 60k

k = ⅓

Rewrite the equation with the value of k

f = ⅓gkj

Find the new value of f

f =⅓ × 5 × 12 × 3 = $\boxed{60}$

Use properties of exponents to write an equivalent expression

Kazeer [188]

First u multiply the numbers in side the parantesis
3³ which is 3•3•3= 9•3=27
next u put the answer back in the parantesis and then multiply using the third power to get the final answer.
(27)³ = ( 27•27•27)= 19683

- Algebraically find the x-coordinates where the line y = 2x – 3 intersects the circle (x – 3)' +(y+1)* = 68.

erastovalidia [21]

Wouldn’t it be -3? i’m not sure tho but if y=2x-3 and the circle is (x-3)+(y+1) they both have (-3)
