I think y is 2 because x is -1 right?
<em>1.) </em><em>x</em>
<em />
<em>2.) </em><em>f(x)</em>
<em />
<em>3.) </em><em>the output (y-value) when x = 2</em>
<em />
<em>4.) </em><em>f(2) = 2</em>
Kelvin would be off because he's using an estimate for Pi because it is endless, so he's rounding at the start and his answer will be incorrect.
Answer:
The Length of monitor is 14.84 inches And Width of monitor is 11.87
Step-by-step explanation:
Given as :
The length of diagonal of rectangular monitor = 19 inches
The length to width ratio is 5:4
So , Let the Length of monitor = 5x
and The Width of monitor = 4x
Now, From Pythagoras theorem
(Diagonal)² = Length² + width²
Or, 19² = (5x)² + (4x)²
Or, 361 = 25x² + 16x²
Or, 41x² = 361
So, x² = 8.804
∴ x = = 2.967 inches
So, The length = 5x = 14.835 inches
And The width = 4x = 11.868 inches
Hence The Length of monitor is 14.84 inches And Width of monitor is 11.87 Answer
Step-by-step explanation:
No. If you distribute the 'x', you get:
The function is quadratic due to the exponetial term of x^2
