<span>Let the distance a string will stretch be l, and the weight attached to the string be w, then l = kw. 9 = 100k => k = 9/100. l = 9/100 w. Therefore, when a weight of 90 pounds is attached, l = 9 / 100 x 90 = 810 / 100 = 8.1 inches.Hope I helped! :) Cheers!I hope that I could help :) sometines those questions are tricky. Let me know if you need additional help</span>

Evaluate each log without a calculator
Mrac [35]

QUESTION 1

The given logarithmic expression is

\log_4(\frac{1}{16})

We rewrite \frac{1}{16} in the index form to base 4.

This implies that;

\log_4(\frac{1}{16})=\log_4(4^{-2})

We now apply the power rule: \log_a(m^n)=n\log_a(m^n).

\log_4(\frac{1}{16})=-2\log_4(4)

Recall that logarithm of the base is 1.

\log_4(\frac{1}{16})=-2(1)

\log_4(\frac{1}{16})=-2

QUESTION 2

The given logarithm is;

\log_2(\sqrt[5]{32})

\log_2(\sqrt[5]{2^5})

This is the same as;

\log_2(2^{5\times \frac{1}{5}})

\log_2(2^{1})

\log_2(2)=1
