Kyle plays softball. His goal is to have a batting average of .400 or greater by the end of the season. The ratio that relates t
gregori [183]

Answer:

The  number of  hits is  T  \ge 30 \ hits

Step-by-step explanation:

From the question we are told that

   The ratio of the number of hits to the number of chances is equivalent to the batting average

   The  number of chances is j =  65 + 10 =  75

    The  number of hit so far is  n =  25

Generally the batting average can be represented mathematically as

      A =  \frac{n + k}{ j}

Here k is the number of additional hits Kyle need to get in order to obtain the batting average of  0.40 or more

 So  

        \frac{25 + k}{ 75}  \ge 0.40

=>     k \ge  5 \  hits

Hence the number of hits for Kyle  to  get a batting average of 0.400  or greater by the end of the season is  

     T  \ge k +  n

=>   T  \ge 5 +  30

=>   T  \ge 30 \ hits

Identify the asymptotes of each function
Maurinko [17]

Answer:

A. x=2, \ f(x)=3

Step-by-step explanation:

The function

f(x)=\dfrac{3}{x-2}+3

is undefined when the denominator is equal to 0. So, when

x-2=0\\ \\x=2

the functin f(x) is undefined and the line x = 2 is vertical asymptote.

The horizontal asymptote is at f(x)=3

So, correct option is

x=2, \ f(x)=3
