Consider the given equation to be f(x) whose first derivative is positive for all real x. This implies f(x) is a strictly increasing function. Thus it has only 1 root.
In case of sales tax , we have to do addition of the tax with the total price. Price of one chicken is $12.99, so price of two chickens = 12.99*2 = $25.98 . And sales tax on each is 6% and 6% of 12.99 =0.06*12.99 = 0.7794. And on two chickens, sales tax=2*0.7794 = 1.5588 . So the total price we need to pay = 25.98+ 1.5588 = 27.5388 = $ 27.54 approx .
We know that the pole is perpendicular to the ground
And that the length of the pole is 20 feet tall, and the base is 15 feet
Now, the guy wire is a wire that provides support to the pole by connecting the top of the pole to the ground
So this represents a right angled triangle (refer image), and the hypotenuse is the length of the guy wire
Using Pythagoras theorem, we can find out the length of the hypotenuse
⇒ Hypotenuse² = Perpendicular² + Base²
⇒ Hypotenuse² = 20² + 15²
⇒ Hypotenuse² = 400+225
⇒ Hypotenuse² = 625
⇒ Hypotenuse = √625
⇒ Hypotenuse = 25
Hence, the correct option is B 25 ft.
