ARCHITECTURE The curve of the archway under a bridge can be modeled by the equation $y = 鈭� \frac{1}{5} x^{2} + 6 x$ , where $x$ and $y$ are measured in feet. Copy and complete the table for each value of $x$ .

Short Answer

Expert verified

$x$	$y$
0	0
10	40
15	45
20	40
30	0

Step by step solution

Step 1. Replace x with 0 and simplify.

Replace $x$ with 0 in the given equation and simplify.

$y = 鈭� \frac{1}{5} {(0)}^{2} + 6 (0) = 0$

Step 2. Replace x with 10 and simplify.

Replace $x$ with 10 in the given equation and simplify.

$y = 鈭� \frac{1}{5} {(10)}^{2} + 6 (10) = 鈭� 20 + 60 = 40$

Step 3. Replace x with 15 and simplify.

Replace $x$ with 15 in the given equation and simplify.

$y = 鈭� \frac{1}{5} {(15)}^{2} + 6 (15) = 鈭� 45 + 90 = 45$

Step 4. Replace x with 20 and simplify.

Replace $x$ with 20 in the given equation and simplify.

$y = 鈭� \frac{1}{5} {(20)}^{2} + 6 (20) = 鈭� 80 + 120 = 40$

Step 5. Replace x with 30 and simplify.

Replace $x$ with 30 in the given equation and simplify.

$y = 鈭� \frac{1}{5} {(30)}^{2} + 6 (30) = 鈭� 180 + 180 = 0$

Step 6. Make a table.

Make a table of obtained values of $y$ for every $x$ value.

$x$	$y$
0	0
10	40
15	45
20	40
30	0
