Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.

Differentiate the following by using "limit"
Nat2105 [25]

Answer:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \frac{   1 }{ 2\sqrt{x } }

Step-by-step explanation:

we want to differentiate the following by using limit:

\displaystyle  \frac{d}{dx}  \sqrt{x}

derivative definition by limit given by

\rm \displaystyle  \frac{d}{dx}  =  \lim _{\Delta x \to 0} \left( \frac{f(x +  \Delta x) - f(x)}{ \Delta x}  \right)

given that,

f(x)=√x

so,

f(x+∆x)=√(x+∆x)

thus substitute:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{\Delta x \to 0} \left( \frac{ \sqrt{x +  \Delta x}-  \sqrt{x} }{ \Delta x}  \right)

multiply both the numerator and denominator by the conjugate of the numerator:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{\Delta x \to 0} \left( \frac{ \sqrt{x +  \Delta x}-  \sqrt{x} }{ \Delta x} \times   \frac{ \sqrt{x +  \Delta x} +  \sqrt{x}  }{\sqrt{x +  \Delta x} +  \sqrt{x}}  \right)

simplify which yields:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{\Delta x \to 0} \left( \frac{ (\sqrt{x +  \Delta x}) ^{2} -  x }{ \Delta x(\sqrt{x +  \Delta x} +  \sqrt{x})}  \right)

simplify square:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{  \Delta x \to 0} \left( \frac{ x +  \Delta x -  x }{ \Delta x(\sqrt{x +  \Delta x} +  \sqrt{x})}  \right)

collect like terms:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{\Delta x \to 0} \left( \frac{  \Delta x }{ \Delta x(\sqrt{x +  \Delta x} +  \sqrt{x})}  \right)

reduce fraction:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \lim _{\Delta x \to 0} \left( \frac{   1 }{ (\sqrt{x +  \Delta x} +  \sqrt{x})}  \right)

get rid of ∆x as we are approaching its to 0

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \frac{   1 }{ \sqrt{x } +  \sqrt{x}}

simplify addition:

\rm \displaystyle  \frac{d  }{dx}   \sqrt{x} =  \frac{   1 }{ 2\sqrt{x } }

and we are done!

Write the equation of the graph shown below in factored form.
Ira Lisetskai [31]

Answer:

  y = (x +2)(x -1)(x -3)

Step-by-step explanation:

For each x-intercept (r) the corresponding factor is (x -r). For x-intercepts -2, 1, 3, the factors are ... (x+2), (x-1), (x-3). Then the equation is ...

  y = (x +2)(x -1)(x -3)

What is the solution to the given system of equations?
bixtya [17]

Depends, what was given for x? For example, 4 times the number given for x minus 3 would be the coordinate and the negative number given for x minus 13 would be your coordinate, I hope this helped you solve it :) if not put the number given for x

In triangle ABC, (angle A) is a right angle and (m angle B) = 45deg.
Ratling [72]
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to x \sqrt{2}, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to 16 \sqrt{2} ft

LENGTH OF ARCS. URGENT.
Alenkinab [10]

Since the angle of the arc is 90°, we'll plug that in for theta. We're finding the length of the arc, so we'll use the circumference formula.
