Answer:
f'(9) = 6
Step-by-step explanation:
f(x) = 6x+7
The derivative is
f'(x) = 6
Evaluated at x=9
f'(9) = 6
51% less.
The length is decreased by 50%, which is the same as being multiplied by 0.5, then it's increased by 40% which is another multiplication by 1.4. So the overall change is 0.5 * 1.4 = 0.7, or the newest rectangle is 70% of the size of the original rectangle. And since the area increases by the square, the newest rectangle has 0.7 * 0.7 = 0.49 of the area as the original rectangle. So it has 51% less area than the original rectangle.

Answer:
Step-by-step explanation:
<u>Given functions</u>
- f(x)= -3/4x
- g(x)= -5x
- h(x)= 5/7x
- j(x)= 11/3x
To compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
<u>The slopes are </u>
<u>Comparing the fractions</u>
- 3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7
And
<u>So the order is </u>
<u>As functions, the order is</u>
