Answer:

Step-by-step explanation:

i) Area of Square = Length^{2}

= 2.6 × 2.6 = 6.76 cm^{2}

ii)

1 dm = 10 cm

1.2 dm = 12cm

Area of Square = 12×12 = 144 cm

2)

1 dm = 0.1 m

16.5 dm = 1.65 m

Area of square = 1.65×1.65 = 2.7225 m^2

= 2.7225 sq m

For question 1:

Part i)

2.6 x 2.6 = 6.76 cm squared

No unit conversions needed

Part ii)

1.2 dm = 1.2 / 1000000 = 0.0000012 cm

0.0000012 x 0.0000012 = 0.00000000000144 cm squared

Question 2:

16.5dm = 16.5/ 1000 = 0.0165 m

0.0165 x 0.0165 = 0.00027225 m squared

I hope this has helped

The table shows the outputs, y, for different inputs, x: Input (x) 3 7 11 15 Output (y) 4 6 8 10 Part A: Do the data in this tab
stiv31 [10]

Answer:

Step-by-step explanation:

x (3,7,11,15)

y (4,6,8,10)

A. This IS a function because u have no repeating x values

B. Data in table :

    when x = 11, y = 8

   relation : f(x) = 5x - 21....when x = 11

                  f(11) = 5(11) - 21

                  f(11) = 55 - 21

                  f(11) = 34.....so when x = 11, y = 34

therefore, the relation f(x) = 5x - 21 has a greater value then the table

C. f(x) = 5x - 21......f(x) = 99

   99 = 5x - 21

   99 + 21 = 5x

   120 = 5x

   120/5 = x

   24 = x <====
