Find the value of k such that lim-->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

Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8. What is

IRISSAK [1]

Answer:

$29500

Step-by-step explanation:

We have been given that Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8%. We are asked to find the amount of property tax that Tariq paid.

To find the amount of property tax paid by Tariq, we need to calculate 11.8% of $250,000.

$\text{Amount of property tax paid by Tariq}=\$250,000\times \frac{11.8}{100}$

$\text{Amount of property tax paid by Tariq}=\$2500\times 11.8$

$\text{Amount of property tax paid by Tariq}=\$29,500$

Therefore, Tariq paid an amount of $29500 in tax.
