the circumference of a circle varies directly as the radius if the circumference is 18 cm when the radius is 3

The circumference of a circles varies directly as its radius,

or the circumference is directly proportional to its radius.

Step-by-step explanation:

There u go pls like it and 5 starts thx

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
