Determine if the function is one-to-one. (5 points)
photoshop1234 [79]

Answer:  NO

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

In order for the function to be one-to-one, it must pass the vertical line test AND the horizontal line test.

The vertical line test is where you draw a vertical line anywhere and the line will not intersect the graph more than one time.  In other words, the function cannot contain a duplicate x-value.

The horizontal line test is where you draw a horizontal line anywhere and the line will not intersect the graph more than one time.  In other words, the function cannot contain a duplicate y-value.

The graph provided passes the vertical line test but fails the horizontal line test. <em>One example is that there are two x-intercepts.</em>

A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you a
Leto [7]

Answer:

Pr =0.75

Step-by-step explanation:

Given

See attachment for wedge

Required

P(x > 5)

The sample space of the wedge is:

S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(S) = 20

The outcomes greater than 5 are:

x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(x>5) =15

So, the probability is:

Pr =\frac{(n(x>5)}{n(S)}

This gives:

Pr =\frac{15}{20}

Pr =0.75

x^2+x-6006=0

x^2+78x-77x-6006=0

x(x+78)-77(x+78)=0

(x-77)(x+78)=0

=>x=77 or x=78
