HELP DUE IN 10 MINS!
zhuklara [117]

Answer:

Step-by-step explanation:

Of that list, only the square and the rectangle have the property you are asking for.

Try drawing it. The parallelogram has a shorter diagonal from the two obtuse angles than the diagonal from the two acute angles.

The rhombus has the same property as the parallelogram.

The kite has a far longer diagonal  from the angle enclosed by the two long sides going to the angle enclosed by the two shorter sides,  than a line going from the angle enclosed by one shorter and one longer side to the other angle made the same way.

3. Find f[h(a+4)], given the functions below. *
mote1985 [20]

Answer:

C 5a^2 +70a +240

Step-by-step explanation:

We have given these following functions:

f(x) = 5x, g(x) = -2x + 1, h(x) = x^2 + 6x + 8

h(a+4)

This function is:

h(a+4) = (a+4)^2 + 6(a + 4) + 8

h(a+4) = a^2 + 8a + 16 + 6a + 24 + 8

h(a+4) = a^2 + 14a + 48

f[h(a+4)]

f(x) = 5x

Thus

f(h(a+4)) = f(a^2+14a+48) = 5(a^2 + 14a + 48) = 5a^2 + 70a + 240

The correct answer is given by option C.
