An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.

If p is inversely proportional to the square of q, and p is 19 when q is 8, determine p when q is equal to 2

Gnom [1K]

Answer:

p = 304

Step-by-step explanation:

Given p is inversely proportional to q² then the equation relating them is

p = $\frac{k}{q^2}$ ← k is the constant of proportion

To find k use the condition p = 19 when q is 8, then

19 = $\frac{k}{8^2}$ = $\frac{k}{64}$ ( multiply both sides by 64 )

k = 1216

p = $\frac{1216}{q^2}$ ← equation of proportion

When q = 2, then

p = $\frac{1216}{2^2}$ = $\frac{1216}{4}$ = 304

Wittaler [7]

Answer:

6*10^-3 > 5*10^-3

Step-by-step explanation:

$6*10^{-3}\\6*\frac{1}{10^{3} }\\6*\frac{1}{1000}\\\frac{6}{1000}=\frac{3}{500}=0.006$

$5*10^{-3}\\5*\frac{1}{10^{3} }\\5*\frac{1}{1000}\\\frac{5}{1000}=\frac{1}{200}=0.005$

0.006>0.005, therefore, 6*10^-3>5*10^-3
