In order to find out, you need to square 45 and see weather it is equal to 40^2+30^2
in the end , 1600 won't be equal to 2500 so it won't form a right triangle.
The graph is concave has two curved part as follows;
- The graph is concave up between;(0, 1), and (1, 0)
- The graph is concave down between; (0, 1), and (-a, 2)
<h3>How can the direction of concavity be found?</h3>
The direction the concave part of the graph faces is given as follows;
The graph is concave up when the concave part faces up
It is concave down when the concave part faces down
From the given diagram, we have;
The graph is concave up between;
(0, 1), and (1, 0)
The graph is concave down between; (0, 1), and (-a, 2)
Where <em>a </em>is in the range; 1 < a < 2

Answer:
$110, $44
Step-by-step explanation:
Let x = the total cost to Stefan
Jim buys for:
bicycle: $138
helmet: $16
total: $138 + $16 = $154
Jim's price of $154 is 140% of Stefan's cost, x.
154 = 140% × x
1.4x = 154
x = 110
Stefan spent $110.
Stefan's profit:
$154 - $110 = $44
Answer: $110, $44
