velikii [3]3 years ago
4 0

Answer:

Vertex : (-2,-121)

Roots : x=9,-13

Step-by-step explanation: Rewrite the vertex form and use this form to fine the vertex (h,k).

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with zero and solve for x.

I hope this helps you out.

SCORPION-xisa [38]

Answer:

(2,3)

Step-by-step explanation:

Rotation through 90 clockwise gives the expression

<em>(</em><em> </em><em>x</em><em> </em><em>,</em><em> </em><em>y</em><em> </em><em>)</em><em>_</em><em>_</em><em>_</em><em> </em><em>(</em><em> </em><em>y</em><em> </em><em>,</em><em>-</em><em> </em><em>x</em><em> </em><em>)</em>

<em>so</em><em> </em><em>whe</em><em>n</em><em> </em><em>you</em><em> </em><em>pu</em><em>t</em><em> </em><em>the</em><em> </em><em>poin</em><em>ts</em><em> </em><em>-</em><em>3</em><em> </em><em>,</em><em>2</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>relat</em><em>ion </em><em>,</em><em> </em><em>it</em><em> </em><em>becom</em><em>es</em>

( -3 , 2 ) ___ ( 2, - -3 )

= ( x, y ) __ ( 2, 3 ). meaning when you rotate -3,2 through 90 clockwise you will get the image ( 2 ,3 )

For a parallel structure of identical​ components, the system can succeed if at least one of the components succeeds. Assume tha
Dennis_Churaev [7]

Using the probability concept, we have that:

a) It would not be unusual to observe one component​ fail, since the probability that one component​ fails is greater than 0.05.

b) It would be unusual to observe two components​ fail, since the probability that two components​ fail is less than 0.05.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. If a probability is less than 0.05, the event is considered unusual.

In this problem, the probabilities are given as follows:

  • 0.21 probability that one component fails, hence not unusual.
  • (0.21)² = 0.0441 probability that two components fail, hence unusual.
