Answer:
Step-by-step explanation:
for right-angled triangle: a^2 + b^2 = c^2
given a = 5 n b = 10
c^2 = 5^2 + 10^2
= 25 + 100
= 125
c = sqrt(125)
= 5*sqrt(5)
Answer:
x = $34.45
Step-by-step explanation:
Solution:-
The company makes a profit of $y by selling widgets at a price of $x. The profit model is represented by a parabola ( quadratic ) equation as follows:

We are to determine the profit maximizing selling price ( x )
From the properties of a parabola equation of the form:

The vertex ( turning point ) or maximum/minimum point is given as:

The profit maximizing selling price of widgets would be x = $34.45.
