Answer:
7 hundredths
Step-by-step explanation:
add 4 to 6 and take away 3
Hello,
Use the factoration
a^2 - b^2 = (a - b)(a + b)
Then,
x^2 - 81 = x^2 - 9^2
x^2 - 9^2 = ( x - 9).(x + 9)
Then,
Lim (x^2- 81) /(x+9)
= Lim (x -9)(x+9)/(x+9)
Simplity x + 9
Lim (x -9)
Now replace x = -9
Lim ( -9 -9)
Lim -18 = -18
_______________
The second method without using factorization would be to calculate the limit by the hospital rule.
Lim f(x)/g(x) = lim f(x)'/g(x)'
Where,
f(x)' and g(x)' are the derivates.
Let f(x) = x^2 -81
f(x)' = 2x + 0
f(x)' = 2x
Let g(x) = x +9
g(x)' = 1 + 0
g(x)' = 1
Then the Lim stay:
Lim (x^2 -81)/(x+9) = Lim 2x /1
Now replace x = -9
Lim 2×-9 = Lim -18
= -18
Answer:
Your answer would be D. The height of NBA basketball players in meters
Step-by-step explanation:
It makes sense for the to be 1-9 inches of rain, a plant 1-9 inches, a phone book 1-9 pounds, but there is not a lot of Basketball players that are only one meter tall. ☺ That would be able impossible.
If e is between them, then the distances DE and EF add to the total, DF. So the answer is just 27 + 34 which is 61, A
