The answer is (A) 32 inches

Step-by-step explanation: Please refer to the attached diagram.

Since we have been given two sides of the television screen, that is, the length and the width, we can calculate the diagonal by simply drawing a line across from one edge to the other edge such that we now have a length, a width, and a diagonal. Simply put, we now have a right angled triangle with two sides given and the third side (the hypotenuse) yet unknown.

At this point we can apply the Pythagoras Theorem in solving for the unknown side. The Pythagoras theorem states that the square of the longest side in a right angled triangle equals the sum of the square of the other two sides of the triangle. This can be expressed as

AC^2 = AB^2 + BC^2

(Please note that ^2 means raised to power 2)

Where AC is the hypotenuse.

Our hypotenuse is represented by X in the attached diagram, hence

X^2 = 15.7^2 + 28^2

X^2 = 246.49 + 784

X^2 = 1030.49

Add the square root sign to both sides of the equation and we now have

X = 32.10

Approximate this to the nearest inch,

X = 32

The TV size is therefore 32 inches

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
