Answer:

see explanation

Step-by-step explanation:

given that V is directly proportional to u and inversely proportional to f , then the equation relating them is

V = \frac{ku}{f} ← k is the constant of proportion

(a)

to find k use the condition when u = 1 and f = 3 , V = \frac{1}{6} , then

\frac{1}{6} = \frac{k}{3} ( cross- multiply )

6k = 3 ( divide both sides by 6 )

k = \frac{3}{6} = \frac{1}{2}

V = \frac{u}{2f} ← equation of proportion

(b)

when f = 4 and V = 1 \frac{1}{4} = \frac{5}{4} , then

\frac{5}{4} = \frac{u}{2(4)} = \frac{u}{8} ( cross- multiply )

4u = 40 ( divide both sides by 4 )

u = 10

Hi, may someone help me with this question? Thank you!:)<br><br> “If f(x) = x^2 + 7, find f(x+2)”
finlep [7]

Answer:

=x^2 +4x+11

Step-by-step explanation:

f(x) = x^2 + 7,

Replace x with x+2

f(x+2) = (x+2)^2 + 7

         = (x+2)(x+2) +7

     FOIL

     = x^2 +2x+2x+4 +7

Combine like terms

    =x^2 +4x+11

What is the square root of 95.54
vladimir2022 [97]
Well this is simple a calculator type problem...but if you are curious as the the algorithm used by simple calculators and such...

They use a Newtonian approximation until it surpasses the precision level of the calculator or computer program..

A newtonian approximation is an interative process that gets closer and closer to the actual answer to any mathematical problem...it is of the form:

x-(f(x)/(df/dx))

In a square root problem you wish to know:

x=√n  where x is the root and n is the number

x^2=n

x^2-n=0

So f(x)=x^2-n and df/dx=2x so using the definition of the newton approximation you have:

x-((x^2-n)/(2x)) which simplifies further to:

(2x^2-x^2+n)/(2x)

(x^2+n)/(2x), where you can choose any starting value of x that you desire (though convergence to an exact (if possible) solution will be swifter the closer xi is to the actual value x)

In this case the number, n=95.54, so a decent starting value for x would be 10.

Using this initial x in (x^2+95.54)/(2x) will result in the following iterative sequence of x.

10, 9.777, 9.774457, 9.7744565, 9.7744565066299210578124802523397

The calculator result for my calc is: 9.7744565066299210578124802523381

So you see how accurate the newton method is in just a few iterations. :P
