Given the quadratic equation:

x^2+5x-5=0

Using the general solution for quadratic equations:

ax^2+bx+c=0\Rightarrow x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

From the problem, we identify:

\begin{gathered} a=1 \\ b=5 \\ c=-5 \end{gathered}

Then:

x=\frac{-5\pm\sqrt{25+20}}{2}=\frac{-5\pm3\sqrt{5}}{2}

And the solution set is:

\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]

F(x)3x+5/x what is f(a+2)
Natalija [7]
F(X) = (3x + 5)/X
F(a + 2) = (3(a + 2) + 5)/(a + 2)
F(a + 2) = (3a + 6 + 5)/(a+2)
F(a + 2) = (3a + 11)/(a + 2).

This would be the final solution.

use algebraic manipulation to find the minimum sum-of-products expression for the function x1x2'x3' + x1x2x4+x1x2'x3x4'
Dennis_Churaev [7]

Answer:

sum of products expression = x₁x₂x₃'  +  x₁x₂'x₄  + x₁x₂x₄

Step-by-step explanation:

Given function ( f ) = x₁x₂'x₃'  +  x₁x₂x₄ + x₁x₂'x₃x₄'

using algebraic manipulation

f = x₁ [ x₂'x₃'  +  x₂x₄ + x₂'x₃x₄' ]

 =  x₁ [ x₂'( x₃' + x₃x₄') +  x₂x₄  ]

next apply Boolean rules

a + bc = ( a + b )(a + c )

a' + a =1

hence

minimum sum-of-products expression = x₁x₂x₃'  +  x₁x₂'x₄  + x₁x₂x₄

\frac{ \tan(58) }{1}  =  \frac{x}{24}

x = how high the kite is

x = 24 × tan(58)

x is approximately 38 meters

Rly need help with this perimeter problem to find perimeter of shaded section! pls give full explanation. ignore notes
stepladder [879]
Well if finding the area of a shape would be multiplying the 2 sides due to the given information that both shaded sides equal to 50, that means 50x50 which is 2500
