which expression is equivalent to the given polynomial expression? (9mn-19m^4n)-(8m^2+12m^4n+9mn)
A. -31m^4n+18mn-8m^2
B. -7m^4n+8m^2
C. -7m^4n+18mn-8m^2
D. -31m^4n-8m^2
9514 1404 393
Answer:
D. -31m^4n-8m^2
Step-by-step explanation:
Eliminate parentheses by distributing the minus sign. Then collect terms:
(9mn-19m^4n)-(8m^2+12m^4n+9mn) = 9mn -19m^4n -8m^2 -12m^4n -9mn
= m^4n(-19 -12) +mn(9 -9) +m^2(-8)
= -31m^4n -8m^2 . . . . . matches choice D

OB. 0.210
OC. 0.214
OD. 0.218
O E. 0.498
Y
Answer:
B. 0.210
Step-by-step explanation:
Range is the minimum value subtracted from the maximum value. In this case 0.004 is the smallest value and 0.214 is the largest.
Range = 0.214 - 0.004 = 0.210 = B
The range set of the given data is 0.21.
The given data sets are,
0.004
0.007
0.011
0.011
0.012
0.020
0.200
0.214
We know that,
In statistics, the range is the difference between the highest and lowest values for a given data collection.
For instance,
if the given data set is 2,5,8,10,3, the range is 10 - 2 = 8.
As a result, the range can also be defined as the difference between the highest and lowest observations.
The range of observation is the name given to the outcome. In statistics, the range indicates the dispersion of observations.
Now to find the range set pf the given data,
Subtract minimum value to maximum value
Since maximum value = 0.214
And minimum value = 0.004
Then range set = 0.214 - 0.004
= 0.21
Thus, range of set ⇒ 0.21

If the mean weight of 3 outfielders on the baseball team is 201 lb and the mean weight of the 6 other players is 232 lb, what is the mean weight of the 9-person team?
Answer:
221.6667
Step-by-step explanation:
Step one is to add all of the players weight together.
- lets write an equation 3(201)+ 6(232)
Now simplify the expression, 603+1392. Add them together to get 1995 LBS
Step two is finding the mean
- The mean is adding up all the numbers and dividing by the amount. So there are 9 players and their total weight is 1995 LBS. take 1995 and divide by 9 to get your answer. This is 221.66667. Make sure to round if the question asks!!!!

Write an equation of the line that passes through the point (6,2) and is perpendicular to the line y=3x+3
Answer:
y = - [tex]\frac{1}{3}[/tex]x + 4
Step-by-step explanation:
To find the slope of a perpendicular line, find the negative reciprocal of the slope.
The slope is 3 so the slope of the perpendicular line would be - [tex]\frac{1}{3}[/tex]
________________
Then use point slope form to find the equation of the perpendicular line:
y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex] )
point = (6, 2)
slope = - [tex]\frac{1}{3}[/tex]
y - 2 = - [tex]\frac{1}{3}[/tex] (x - 6)
________________
If you want it in slope intercept form, you can just rearrange the equation:
y = 2 - [tex]\frac{1}{3}[/tex]x +2
y = - [tex]\frac{1}{3}[/tex]x + 4
y = x + 3

As I was solving this equation, I got:
x^-2
-------
x^10
I moved x^-2 down with x^10
So in x^-2's place, I placed a positive 1.
1
----------------------
x^10 times x^-2
The radical rule here is to pretty much subtract ahead. However, this extremely smart person said something like if I move a negative number to the denominator, it becomes positive. However, in this case, x^-2 stays the same.

Answer:
[tex]\frac{1}{x^{12} }[/tex]
Step-by-step explanation:
Given [tex](\frac{x}{x^{-5}})^{-2}[/tex]
The Negative Exponent Rule states that, [tex]a^{-n} = \frac{1}{a^{n}}[/tex]
Basically, since you're raising the fraction inside the parenthesis to a negative exponent, the whole fraction becomes a denominator of 1: [tex]\frac{1}{(\frac{x}{x^{-5}})^{2}}[/tex]
Then, you'll have to work on the denominator:
[tex]\frac{1}{(\frac{x}{x^{-5}})^{2}} = \frac{1}{\frac{x^{2} }{(x^{-5})^{2}}}[/tex]
Next, you'll have to work on the divisor of x² (in the denominator), [tex](x^{-5})^{2}[/tex] by using the Power-to-Power Rule of Exponents: [tex](a^{m})^{n} = a^{mn}[/tex], which results in:
[tex](x^{-5})^{2} = x^{-10}[/tex]
Since it is a negative exponent, you'll have to apply the Negative Exponent Rule once again to the denominator.
[tex]\frac{1}{(\frac{x}{x^{-5}})^{2}} = \frac{1}{\frac{x^{2} }{(x^{-5})^{2}}} = \frac{1}{\frac{x^{2} }{x^{-10}}} = \frac{1}{\frac{x^{2} }{\frac{1}{x^{10}}}}[/tex]
At this point, you could apply the Fraction rule onto the denominator: [tex]\frac{a}{\frac{b}{c}} = \frac{a*c}{b}[/tex]
So the denominator now becomes:
[tex]\frac{1}{\frac{x^{2} }{\frac{1}{x^{10}}}} = \frac{1}{x^{2}*x^{10} }[/tex]
Finally, you could apply the Product Rule of Exponents, [tex]a^{m}a^{n} = a^{m + n }[/tex] onto the denominator:
[tex]\frac{1}{x^{2}*x^{10} } = \frac{1}{x^{2+10}} = \frac{1}{x^{12} }[/tex]
Therefore, the correct answer is: [tex]\frac{1}{x^{12} }[/tex]
