Answer:
108
Step-by-step explanation:
Limit as x approaches 9 of x^2 -81/sqrt of x - 3
First substitute x into the expression
= 9²-81/√9 - 3
= 81-81/3-3
= 0/0 (indeterminate)
Apply l'hospital rule
= lim x -> 9 d/dx(x²-81)/√x - 3
= lim x -> 9 2x/1/2√x
Substitute x = 9
= 2(9)/1/2√9
=18/1/(2(3)
=18 × 6/1
= 108
Hence the limit of the function is 108
Find the quotient 4.2 ÷7=> 4.2 is our dividend which is a decimal number. 4 as the whole number and 2 is the decimal number.=> 7 is our divisor that will be use to divide with 4.3Let's now start solving:=> 4.2 / 7 = 0.6<span>Thus the quotient of the given data is 0.6 which is also a decimal number same as the divisor.</span>
