3 0

Answer:

A

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

\sqrt{x^2} = ± \sqrt{16} ← note plus or minus sign

x = ± 4

Since 4² = 4 × 4 = 16 and

(- 4)² = - 4 × - 4 = 16

E varies directly with the square root of C. If E=40 when C=25 find: E when C= 49
tiny-mole [99]

Answer: E = 56

Step-by-step explanation:

E is proportional to √C

To remove proportionality, introduce a constant (k).

E = k × √C

From question,

E = 40 and C = 25

So,

40 = k ×√25

40 = k × 5

k = 8

Now,

C = 49

k = 8

E = ?

E = k√C

E = 8 × √49

E = 8 × 7

E = 56
