The value of x that will result for the rational expression to be undefined will be the values that will give 0 value for the denominator.
A. 7
<span>2(7)^2 -32 = 66
</span>
<span>B. 4
</span>2(4)^2 -32 = 0 <span>-------> undefined</span>
C. 2
2(2)^2 -32 = -24
<span>D. -2
</span>2(-2)^2 -32 = -24
<span>E. -4
</span>2(-4)^2 -32 = 0 -------> undefined
F. -7
2(-7)^2 -32 = 66
Answer:
The answer is 720 ways.
Step-by-step explanation:
Total friends who volunteered = 10
Total number of jobs that have to be done = 3
Here order matters, so it is a permutation question.
We can use the formula nPr.
= 
= 720 ways.
The second way to solve this is:
Susan can choose the first person to do a job in 10 ways
Then the second job can be done in 9 ways and the third in 8 ways.
Total becomes = 
ways
Answer: A:60%
Step-by-step explanation:
Since the scores for a golf tournament are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = scores for the tournament.
µ = mean score
σ = standard deviation
From the information given,
µ = 210
σ = 80
We want to find the probability percent of golfers that scored less than Ella. It is expressed as
P(x < 230)
z = (230 - 210)/80 = 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.5987
Therefore, the percent of golfers that scored less than Ella is
0.5987 × 100 = 59.87
Approximately 60%

Answer:
a) 1.59967 * 10 ^-12
b) 7.52711497
c) 1.590778098 * 10^-1
Step-by-step explanation:
a= 3.47 x 10^-6,
b=4.61 x 10^-7,
c=5.52 x 10^-7
a) a*b = 3.47 x 10^-6* 4.61 x 10^-7
We multiply the numbers out front and add the exponents
(3.47*4.61) * 10^(-6+-7)
15.9967 * 10^-13
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the left and add 1 to the exponent
1.59967 * 10^(-13+1)
1.59967 * 10 ^-12
b) a/b = 3.47 x 10^-6/ 4.61 x 10^-7
We divide the numbers out front and subtract the exponents
(3.47/4.61) * 10^(-6- -7)
(3.47/4.61) * 10^(-6+7)
.752711497* 10^1
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the right and subtract 1 from the exponent
7.52711497* 10^1-1
7.52711497
c) c/a = 5.52 x 10^-7/3.47 x 10^-6
We divide the numbers out front and subtract the exponents
(5.52/3.47) * 10^(-7- -6)
(5.52/3.47) * 10^(-7+6)
1.590778098 * 10^-1
