Approximate <em>R'</em> by using a linear approximation: for <em>x</em> close enough to 24, you have
<em>R'(x)</em> ≈ <em>L(x)</em> = <em>R' </em>(20) + <em>R''</em> (20) (<em>x</em> - 20)
Then
<em>R'</em> (24) ≈ <em>R'</em> (20) + <em>R''</em> (20) (24 - 20) = -4 + 50 (24 - 20) = 196
Answer:
7 2/3
Step-by-step explanation:
Do 23 divided by 3 = 7 2/3.
<span>(4x - 3x</span>²<span> + 5) + (2x</span>²<span> -5x + 1)
</span>= 4x - 3x² + 5 + 2x² - 5x + 1 //Open brackets
= -x² - x + 6 //Combine like terms
3 miles. Using cross-multiplication, 3×4 = 12 and 4×1 = 4, so 12/4 = 3.
Ya I think it is also the second one
