Identify the function that contains the data in the following table:Х-20o235f(x)531224O f(x) = x/ + 1O f(x) = x - 21O f(x) = lx
kirill [66]

To identify the function that contains the data in the table, we should first visualize the data.

A graph of the data is shown below:

From the plot above, we can identify that:

The graph above is a graph of f(x) = |x|, translated to the right 2 units and translated upwards 1 unit.

Hence, the function is:

f(x)\text{  = |x-2| + 1}

Answer:

Option D

The formula for the area of a triangle is . What is the length of the base, b, of a triangle with an area, A, of 110 m2 and a he
vodka [1.7K]

Answer:

b = 22 m

Step-by-step explanation:

The formula for calculating the area (A) of a triangle is

A = \frac{1}{2} bh

multiply both sides by 2 to eliminate the fraction

2A = bh ( divide both sides by h )

b = \frac{2A}{h}, hence

b = \frac{2(110)}{10} = \frac{220}{10} = 22 m
