s(x)=2x+4;\ D_s=\mathbb{R}\\\\t(x)=5x;\ D_t=\mathbb{R}\\\\D_s=D_t\\\\(s+t)(x)=s(x)+t(x)=2x+4+5x=7x+4\\\\(s-t)(x)=s(x)-t(x)=2x+4-5x=-3x+4\\\\(s\times t)(x)=(2x+4)\times5x=10x^2+20x

Isaac’s television is 25 inches wide and 18 inches high. What is the diagonal size of Isaac’s television? Round to the nearest t
ikadub [295]

Answer:

Step-by-step explanation:

The television takes the shape of a rectangle whose width is 25 inches and whose height is 18 inches. To determine the length of the diagonal, we will apply Pythagoras theorem. It states that

Hypotenuse^2 = opposite^2 + adjacent^2

From the given information,

Adjacent side = 25 inches

Opposite side = 18 inches

Diagonal = hypotenuse.

Therefore

Diagonal^2 = 25^2 + 18^2

Diagonal^2 = 625 + 324 = 949

Take square roots of both sides of the equation, it becomes

Diagonal = √949 = 30.805 inches

Approximately 30.8 inches to the nearest tenth.
