Answer:
Step-by-step explanation:
<em><u>Givens</u></em>
4 sides = 4*p
3 sides = 3(4p) = 12p
Other sides
10
12
4
Total length = 138 inches
<em><u>Equation</u></em>
4p + 12p + 10 + 12 + 4 = 138
<em><u>Solution</u></em>
Collect like terms
16p + 26 = 138
Subtract 26 from both sides
16p + 26 - 26 = 138 - 26
16p = 112
Divide by 16
16p/16 = 112/16
p = 7
<em><u>Longest Side (Answer)</u></em>
7 * 4 = 28 inches
H
We can use the subtraction property of logs to expand the right side of the equation:
log(1/H*) = log(1) - log(H*)
No matter what base we’re using, log(1) = 0, so this simplifies to -log(H*). We’re also given a pH value of 3.6, so we can substitute this value into the original equation along with -log(H*) to get
3.6 = -log(H*)
Multiplying by -1 on both sides:
-3.6 = log(H*)
And rewriting in exponential form:
H* = 10^(-3.6) = 0.0003 (rounded to the nearest ten thousandth)
