Answer:320 sq in

Step-by-step explanation:

To calculate how much fabric is needed to cover the cushion, add the area of each rectangular section.

l = 12 in, w = 7 in, h = 4 in

Rectangle 1 area (l × h): 12 in × 4 in = 48 sq in

Rectangle 2 area (w × h): 7 in × 4 in = 28 sq in

Rectangle 3 area (l × w): 12 in × 7 in = 84 sq in

Rectangle 4 area (w × h): 7 in × 4 in = 28 sq in

Rectangle 5 area (l × h): 12 in × 4 in = 48 sq in

Rectangle 6 area (l × w): 12 in × 7 in = 84 sq in

Now, add all the areas together.

48 sq in + 28 sq in + 84 sq in + 28 sq in + 48 sq in + 84 sq in = 320 sq in

Is the following relation a function? (4,2), (1,1), (0,0), (1, -1), (4, -2). Give the domain and range.
Vlada [557]
(x,y)
to be  a function
for every x, ther must be only 1 y to corespond to it
basically, x must NEVER repeat with a different y
list them

ah, we see (1,1) an d(1,-1)
also (4,2) and (4,-2)
double offense
1 repeats with 1 and -1
4 repeats with 2 and -2

not a function

domain is all x values
range is all y values
if they repeat, don't list them

domain=(0,1,4)
range=(-2,-1,0,1,2)

The table shows ordered pairs of the function y = 16 0. 5x. A 2-column table with 6 rows. The first column is labeled x with ent
zvonat [6]

Option 3 is the correct answer. The missing values of (x, y) is (8, 20).

<h3>How do you find out the values?</h3>

Given that the function is,

y = 16 + 0.5x

The function is a linear equation that can be solved graphically. The values of both variables x and y can be found on different points along with the straight-line graph.

Also, for every value of x, there is a corresponding value of y.

For the given options, we put the values of x to find the corresponding value of y.

For option 1, put x = 0 in the given function,

y = 16 + 0.5\times 0\\y = 16

But for x=0, y= 18, hence option 1 is not correct.

For option 2, put x = 5 in the given function,

y = 16 + 0.5\times 5\\y = 18.5

But for x=5, y= 19.5, hence option 2 is not correct.

For option 3, put x = 8 in the given function,

y = 16 + 0.5\times 8\\y = 20

But for x=8, y= 20, hence option 3 is the correct answer.

Hence we can conclude that option 3 is the correct answer. The missing values of (x, y) is (8, 20).
