Answer:

2.5 ml .

7.7 % to the nearest tenth.

Step-by-step explanation:

The absolute error is 32.5 - 30 = 2.5 ml.

The percent error is (2.5 / 32.5) * 100 =   7.69%

Answer:

E: L is perpendicular to a line with slope -\frac{3}{2}.

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of \frac{2}{3} is \frac{3}{2} (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of \frac{2}{3} is -\frac{3}{2}. This represents the slope of a line that is perpendicular.

Answer:

f(x) = -4x - 2

Step-by-step explanation:

To derive the function rule in slope-intercept form, f(x) = mx + b, we need to find the slope, m, and the y-intercept, b, of the graph given.

Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{0 -(-1)} = \frac{-4}{1} = -4

m = -4

The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.

Substitute m = -4, and b = -2 into f(x) = mx + b.

The function rule in slope-intercept form would be:

f(x) = -4x +(-2)

f(x) = -4x - 2
