Un cateto, en geometría, es cualquiera de los dos lados menores de un triángulo rectángulo, los que conforman el ángulo recto. El lado de mayor medida se denomina hipotenusa –el que es opuesto al ángulo recto. La denominación de catetos e hipotenusa se aplica a los lados de los triángulos rectángulos exclusivamente.

A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the obse

pashok25 [27]

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

Suppose the angle made by the maple tree is x

$\Rightarrow \cos x=\dfrac{12}{16}$

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

$\Rightarrow \cos x=\dfrac{y}{12}$

Substitute the value of $\cos x$

$\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}$

Find all rational solutions of the equation x8−4x5+13x3−7x+1=0.

drek231 [11]

Answer:

The rational roots of the equation are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

Step-by-step explanation:

We have to find the rational solutions of the algebraic equation:

$x^8-4x^5+13x^3-7x+1=0.$

This equation could also be written as:

$(x+1)(x^7-x^6+x^5-5x^4+5x^3+8x^2-8x+1)=0$

for finding the roots of the equation we have to find the possible values of x.

Clearly the equation has 8 roots as the degree of the equation is 8.

from the graph of the following function we could see that the rational roots of the function are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

The rest 4 roots of the equation are the complex roots.
