Answer:

I ≈ 251188643

Step-by-step explanation:

Given

R = logI [ note log I = log_{10} I ]

Using the rule of logarithms

log_{10} x = n ⇒ x = 10^{n}

Substitute R = 8.4 into the equation, then

logI = 8.4

I = 10^{8.4} ≈ 251188643

The width of a rectangle is 4 feet and the diagonal length of he rectangle is 13 feet what is the measurement is the closest to
AURORKA [14]

Answer:

The length is APPROXIMATELY equal to 12.4.

Step-by-step explanation:

Use the converse of the Pythagorean Theorem (a^{2}+b^{2}=c^{2} [where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:

13^{2} = 169

4^{2} =16

169-16=153.

\sqrt{153} ≈ 12

or

\sqrt{153}=12.36931688

or if the problem has to be exact (using radicals)

3*\sqrt{17}

I hope this helps ;)
