Answer:
-3.69
Step-by-step explanation:
Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:
Now lets work out this problem:
Using calculator, we take the values of Ln 16 and Ln 13 as:
Ln 16 = 2.7726
Ln 13 = 2.5649
Now, we can solve for x:
x is -3.69 (rounded to 2 decimal places)
Answer:
36 oz
Step-by-step explanation:
Get the other options down to 12oz units for their price and then you can compare which one is the cheapest for 12oz.
12oz = $1.99
36oz/3 = 12oz so $2.59/3 = $ .86
48oz/4= 12oz so $3.99/4 = $1.00
60oz/5= 12oz so $4.59/5 = $ .92
So looking at the breakdown, the 36oz one is the cheapest because for that price for a third of it comes out to .86 cents.

Required
The value of x that makes l and m parallel
Let the angles be ABC (See attachment 2)
is corresponding to 50 degrees. So:
is corresponding to 55 degrees. So:
This means that:
Solve for x
<h3>
Answer:</h3>
<em>None of the above</em>. All the answers refer to <em>price</em>. The given equation refers to <em>value</em>. We imagine price may stay the same or actually increase year-to-year. The problem statement gives insufficient information to conclude anything about <em>price</em>.
Math is about attention to detail. The equation tells you ...
... The <em>value</em> of the boat decreases by 12% every year.
<h3>
Step-by-step explanation:</h3>
The value of the boat is multiplied by 0.88 each time X increases by 1. That means the value is 88% of what it was the year before, <em>a decrease of 12%</em>.
