What is the shortcut method in learning integration formulas?
blondinia [14]
There is no real shortcut in learning integration formulas. You should take time learning and understanding how the formulas are derived until you are familiar with the formulas and you can easily recall the formulas. Hope this answers the question.

The length of time required for the periodic maintenance of an automobile or another machine usually has a mound-shaped probabil
maks197457 [2]

Solution :

Mean time for an automobile to run a 5000 mile check and service = 1.4 hours

Standard deviation = 0.7 hours

Maximum average service time = 1.6 hours for one automobile

The z - score for 1.6 hours = $\frac{1.6-1.4}{0.7 / \sqrt{50}}$

                                           = 2.02

Now checking a normal curve table the percentage of z score over 2.02 is 0.0217

Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!<br><br> Which equation matches the graph?
tatyana61 [14]

Answer:  D) -2 |x| - 2

<u>Step-by-step explanation:</u>

A v-shaped graph is an absolute value graph.  

The general form of an absolute value equation is: y = a |x - h| + k

where (h, k) represents the vertex and "a" represents the vertical stretch (aka slope).  

The vertex of the given graph is (0, 2), however the graph is inverted (upside-down) which is a reflection across the x-axis.  Therefore,

  • a = -2
  • (h, k) = (0, -2)
<h2>                    --> y = -2 |x| - 2</h2>
