Question

Use your calculator to find the value of y if x equals 2 round to the nearest hundredth

Answer 1

Substitute the value of x into the equation.

`y=9(1.1)^2`

Square 1.1 to obtain the following.

`y=9(1.21)`

Multiply 9 by 1.21.

`y=10.89`

If a calculator will be used, press the following.

1. Press 9

2. Press (

3. Press 1.1

4. Press )

5. Press ^

In some calculators, instead of the caret (^), they use x².

6. Press 2

7. Press =

Thus, the value of y is 10.89.
