Sabemos que os pontos (-2, 6) e (4, 0) pertencem ao gráfico de uma função afim, dada por f(x) = ax + b, com a e b constantes reais. É correto afirmar que: (A) a + b = 5. (B) f(x) é uma função decrescente. (C) f(x) é uma função crescente. (D) f(-1) = 3.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

160
