A room covers 299.6 square feet. A painter paints the room in three days. The first day he covers 2/7 of the area. The next day
Trava [24]

Answer:

<em>On day the he covers </em>128.4 ft²

<u>Step-by-step explanation</u>:

Lets first figure out how much he has done so far

To figure out how much he does we can use a proportion

Set up a proportion for first day

2/7 = x/299.6

Solve the proportion

2×299.6÷7 = 599.2/7 = x

x = 85.6

<em>He covered 85.6 sq/ft on day 1</em>

Find day two

85.6 * 2 = 171.2

Find how much is left to do on day 3

299.6-171.2 = 128.4 ft²

Question: Consider the domain (D) and rule of each function. Determine the range of the function. 1. D = {0, 1, 2, 3}; f(x) = 3x
Maksim231197 [3]

For every function you need evaluate the function for every value in the domain D. And the collection of this values correspond to the range of the function.

1. D = \{0,1,2,3 \}, R = \{f(0), f(1), f(2), f(3) \} = \{-5, -2, 1, 4 \}.

2. D = \{-1,0,1 \}; R= \{f(-1), f(0), f(1)\} = \{0, 1, 0 \} = \{0,1\}

3. D = \{-2,-1,0,1 \}; R = \{f(-2), f(-1), f(0), f(1) \} = \{0, -2, -2, 0 \} = \{-2,0\}

4. D = \{0,1,2,3 \}; R =\{f(0), f(1), f(2), f(3) \} = \{3, 1, -1, -3 \}
