Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
Answer:
So the final answer is

Step-by-step explanation:
Radicals:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.
The given expression is

Now take common radical out so we will get

Now add the Parenthesis part.

So the final answer is

Answer:
Their best investment when they retire in 40 years would be option B.
Step-by-step explanation:
Ragai and Carly invest the $1000 received for their wedding for 40 years.
From the diagram,
In option A, the initial investment do not increase at a constant rate yearly.
In option B, the amount invested increase by $75 yearly.
In option C, the yearly increase does not have a steady value.
In option D, the amount invested increases by a n + consecutive odd values yearly. Where n is the increase of the previous year.
Their best investment when they retire in 40 years would be option B because it would yield the highest profit.
