Answer: The vertical asymptoms are " x = 3" and " x = -3 " .
__________________________________________________
The answer is: " x = ± 3 " .
__________________________________________________
Explanation:
________________________________________________________
The "denominator" cannot equal "0" ; since one cannot "divide by "0" ;
So; set the "denominator" equal to "0" ;
________________________________________________________
→ " x² − 9 <span>= 0 " ; Solve for all values of "x" ;
</span>
Add "9" to each side of the equation:
→ x² − 9 + 9 = 0 + 9 ;
to get:
→ x² = 9 ;
Take the square root of each side of the equation;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ √(x²) = √9 ;
→ |x| = 3 ;
→ x = <span>± 3 .

Answer:
At least 6907 people.
Step-by-step explanation:
Population std deviation = sigma= 10.6
Since population std deviation is known, we can use normal probability table to get sample size from confidence interval.
The sample mean weight loss is within 0.25 lb of the true population mean.
Hence margin of error < 0.25
Margin of error = z critical (std dev/n) where n = sample size
Z critical for 95% = 1.96
Hence 0.25 >1.96(10.6)/sq rt n
Simplify to get
sq rt n > 1.96(10.6)/0.25 = 83.104
Square both the sides to get
n > 83.104 square = 6906.27
i.e. sample size should be atleast 6907.
Hi! I got you! The answer is 32768, the third option! To do this you enter your numbers into the solution first number(common ratio)^n-1. When inputted you get: -2(-4)7 and that equals the third answer.

The answer is
-17 < x < 8
Answer:
a) 63°
b) 127°
Step-by-step explanation:
Complements are 90° while supplements are 180°.
So you need to find the complement of 27°. So, 90-27=63
To find the supplement, it is 180-53=127
