The table shows the cost of taking a rideshare trip. Which description correctly reflects the way the charges are calculated?
1 answer:
The table is an illustration of a linear function.
The description of the charges is: <em>A) The ride requires a $14 initial fee, plus 50 cents per mile driven</em>
<em />
The base fee is the charges, when the number of miles is 0
From the table;
y = $14, when x = 0
So, the base fee is $14
Next, we calculate the slope (m)
From the table, we have:
The above means that:
The cost per mile is $0.5 (i.e. 50 cents)
Hence, the description of the charges is: <em>A) The ride requires a $14 initial fee, plus 50 cents per mile driven</em>

Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
