Question

H varies directly to the cube of c . When H= 40 , C= 2 Express H in terms of C.​

Answer 1

Answer:

20 times of the value of C

Step-by-step explanation:

if we think c as x than h is 20 x

so the value oh h is about 20 times of c..

thanks..

Answer 2

Concept:

The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. It is symbolised by the proportional sign ∝. Since the other variable is reversed in this case, the inversely proportional relationship is really represented by the same symbol.

For instance, if x and y are two quantities or variables that are intimately linked to one another, we can say x y. The ratio of x and y becomes equal to a constant when the proportionality sign is removed, for example, x/y = C, where C is a constant. In contrast, x and y are represented as x ∝1/y or xy = C in the case of inverse proportion.

Given:

H varies directly to the cube of c

Find:

When H= 40 , C= 2 Express H in terms of C.​

Solution:

H α C

⇒H =kC³

Substituting H= 40 , C= 2

40 =k2³

⇒40 = 8k

⇒k =5

So, H = 5c³

Therefore, H can be expressed in terms if c by following equation ,H=C³
