Number of boys enrolled is 105

<em><u>Solution:</u></em>

Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls

There are 245 total preschoolers

Ratio of boys and girls = 3 : 4

Number of boys : number of girls = 3 : 4

Let the number of boys be 3x

Let the number of girls be 4x

Total number of preschoolers = 245

Therefore,

number of boys + number of girls = 245

3x + 4x = 245

7x = 245

x = 35

Number of boys = 3x = 3(35) = 105

Thus number of boys is 105

Find the value of k such that lim--&gt;4 (x^2+x-k)/(x-4) exists
7nadin3 [17]

Answer:

k=20

Step-by-step explanation:

when x approaches 4, the denominator x-4 approaches 0

if the denominator is 0, it means that this is invalid

if the function is a number over 0 when x=4, it represents a vertical asymptote, which means no limit

so the only way possible to let there be a limit is to let the function be 0/0 when we plug in x=4

so x^2 + x - k = 0 when x = 4

4^2 + 4 - k = 0 ==> 20 - k = 0 ==> k = 20
