Find two positive real numbers whose product is a maximum. the sum is 80
Eduardwww [97]
Let's say the numbers are "a" and "b"

thus \bf y=ab\qquad 
\begin{cases}
a+b=80\\
b=80-a
\end{cases}\implies y=a(80-a)\implies y=80a-a^2\\\\
-----------------------------\\\\
\cfrac{dy}{da}=80-2a

set the derivative to 0, and check the critical points, there's only one anyway

and do a first-derivative test, to see if it's a maximum

11. What is the value of x in the figure at the right? (Examples 3 and 4)
natka813 [3]

Answer:

x = 11

Step-by-step explanation:

  • Vertically opposite angles are equal
  • Angles around a point add up to 360°

Therefore, 15x + 15x + 15 + 15 = 360

\implies 30x+30=360

\implies 30x=330

\implies x=11

The perimeter of a frame is 24 inches.The width is 5 inches. What is the length
Kisachek [45]
Assuming the frame is rectangular, the perimeter is 2*width + 2*length. so 5*2 + 2*length = 24. subtract ten from both sides to get the 14 = 2*length. the length = 7.

Law Incorporation [45]

Answer:

a.) 70*

b.) 60*

Step-by-step explanation:
