What is the x-intercept of the group of the function f(x) =x2 -16x + 64

Dimas [21]

The x-intercept of a function is basically it's roots. So when you factor out the function f(x) = x^2 - 16x + 64 you get

(x-8)(x-8)

x = 8

So x-int. is (0,8) or x = 8

The diagonals of a rhombus are 16 cm and 12cm. find its length

igomit [66]

Answer:

l=10 cm

Step-by-step explanation:

In a rhombus, the diagonals are cut into identical lines at the intersection.

This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.

I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side
