4 0

Answer:

A) 90%

Step-by-step explanation:

We know that by the learning curve, as cumulative output doubles the cumulative average time taken per unit decreases by a constant percent and the constant percent is the learning rate.

We need to double output 2 times in order to get from 1 to 4, so, we get the following:

10*n^2=8.1\\n^2=0.81\\n=0.9=90%

The conclusion is that <u>the learning curve</u> for this operation is 90%.

Find the point of depression from point A to point C
lesya [120]

The angle of depression equals 32.


A way that you can solve this is by finding angle c. Angle C would be the same as the angle of depression because of alternate angles being congruent.

So you do the triangle angle sum theorem.

58+90+x=180

Simplify

148 +x=180

Subtract 148 from both sides

x=32

So Since angle c equals to 32 degrees, then the angle of depression is also 32 degrees.
