Answer: Option a.

Step-by-step explanation:

Make the denominator equal to zero and solve for x, as following:

x^{2}+8x-9=0

Choose two numbers whose sum is 8 and whose product is 9.

Then:

(x-1)(x+9)=0\\x=1\\x=-9

Therefore, based on this, you can conclude that the function is continuous at everty real number except x=1 and x=-9.

There are 9 different colors of paint to choose from. Out of the 9 colors, how many ways can 4 different colors be chosen?
gregori [183]
This is the concept of combination, the number of ways 4 different color can be chosen from 9 different colors will be:
9C4
=(9!)/(4!(9-4)!)
=362,880/(24×120)
=362,880/2880
=126
thus the number of ways is 126 ways

A ball is thrown straight up with a speed of 12 meters per second near the surface of Earth. What is the maximum height reached
Elena-2011 [213]

Answer:

maximum height =7.347m

Step-by-step explanation:

maximum height = (U²sin²θ)/2g

where θ = 90° as the ball is thrown straight up.

sin90°=1 , so our formula reduces to;

H= U²/2g

U=12m/s  , g=9.8m/s²

H= 12²/(2*9.8)

H=7.347m
