Answer:

2) II and IV

Step-by-step explanation:

A function will have only one output value for any given input.

I. The table has two different outputs for an input of x=2.

II. The first values of the ordered pairs are all unique. This is a function.

III. The graph shows two different output values for each x input that is greater than 0.

IV. A polynomial always represents a function.

The representations in II and IV are functions.

Given f(x)=x^2−2x−5. Enter the quadratic function in vertex form.

FrozenT [24]

Answer:

$f(x) = (x-1)^2-6$

Step-by-step explanation:

Rewrite the quadratic using the method of completing the square:

$x^2-2x-5=(x^2-2x+1)-1-5=(x-1)^2-6\\f(x) = (x-1)^2-6$

From this form it is immediately clear that the vertex of the parabola is at x=1 and its y-intercept at -6.

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.

vfiekz [6]

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)

25.12 + 56 (Add 25.12 & 56.)

81.12 cm²

The area of the figure is 81.12 cm².
