Answer:
D) [tex]15x^8y^3[/tex]
Step-by-step explanation:
Area = Length * Breadth
Area = [tex]5x^6y^2*3x^2y[/tex]
Apply exponent rule: [tex]a^b*a^c=a^{b+c}[/tex]
Therefore,
Area = [tex]5x^{6+2}y^2* \:3y[/tex]
Area = [tex]5x^8y^2*3y[/tex]
Apply exponent rule as mentioned above:
Area = [tex]5x^8y^{2+1}* \:3[/tex]
Area = [tex]5x^8y^3*3[/tex]
Multiply 3:
[tex]15x^8y^3[/tex]

Answer:
Any value of m, except when m = -12.7, will make the expression equal to 6.35
Step-by-step explanation:
The equation you are given is:
6.35 = 12.7 + m / m + 12.7
First you need to know the rule that anything divided by itself will equal 1.
So no matter what number you use to substitute for m it will equal one because both the top and bottom of the division sign are the same. Except if you use negative 12.7 or a to high of a negative which will cause it to equal -1 which multiplied by 6.35 would equal -6.35
The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n = −m − a n=a+m n=m−a n = a − m
Answers
Answer:
[tex]n = m - a[/tex]
Step-by-step explanation:
Given
[tex]a = m - n[/tex]
Required
Solve for n
[tex]a = m - n[/tex]
Add n to both sides
[tex]a + n = m - n + n[/tex]
[tex]a + n = m[/tex]
Subtract a from both sides
[tex]a - a + n = m - a[/tex]
[tex]n = m - a[/tex]

Lesson 1-1: The periodic comet named Johnson has been seen at every return since its discovery in 1949, as shown in the table below: Occurrence Year Seen 1- 1949 2 1956 3 1963 4 1970 Use the table for Items 1-5. Describe any pattern you see in the table. Write the values in the second column at the table as a sequence. Identify the common difference. If the pattern continues, in which of the following years will the comet be visible again? A. 2017 B. 2018 C. 2019 D. 2020 About how many times would the Johnson comet be visible during a typical person’s lifetime? Explain your reasoning. 5. Reason abstractly. A man was born during a year in which the Johnson comet was visible in the sky. The next time that the comet was visible after the man’s birth year was in 2005. In what year was the man born? The table to use is attached to the question.
Answers
Answer:
Step-by-step explanation:
Occurrence Year seen Difference
1 1949 -
2 1956 1956 - 1949 = 7
3 1963 1963 - 1956 = 7
4 1970 1970 - 1963 = 7
Difference between each successive term of year seen = 7 years
Therefore, there is a common difference of 7 years between each successive term.
Function defining the year seen will be a linear function and will increase in the same pattern. (multiple of 7 years)
2017 - 1970 = 47 (It's not the multiple of 7)
2018 - 1970 = 48 (It's not the multiple of 7)
2019 - 1970 = 49 (multiple of 7)
2020 - 1970 = 50 (It's not the multiple of 7)
Therefore, comet will be seen next in 2019.
Option (C) will be the answer.
If a person is born in 2005
Then difference between 2005 and 1949 = 56 years
Number of times comet seen after 1949 = [tex]\frac{56}{7}=8[/tex] times
Total number of comet seen in the lifetime = 8 times

D. The function is positive when x > 0.
Answers
Answer:
The correct option is;
D. The function is positive when x > 0
Step-by-step explanation:
The reciprocal parent function is of the form;
[tex]y = \dfrac{a}{x - h} + k[/tex]
Where;
h = The horizontal translation
k = The vertical translation
a = The orientation of the graph
Therefore, whereby we have, h = 0, k = 0. and a = 1, the equation becomes;
[tex]y = \dfrac{1}{x - 0} + 0 = \dfrac{1}{x}[/tex]
Therefore, the value of the function y is positive when x > 0 and is negative when x < 0.

if f(x) = -x^2+4x-9 and g(x) = x - 8 find g(f(-1)).
Answers
Answer: g(f(-1))=-22
Step-by-step explanation:
To find g(f(-1)), you want to first want to solve f(-1). Once you solved that, you plig the answer you get into g(x). Then, you will have your final answer.
f(-1)=-(-1)²+4(-1)-9 [exponent]
f(-1)=-1+4(-1)-9 [multiply]
f(-1)=-1-4-9 [subtract from left to right]
f(-1)=-14
We have found that f(-1)=-14. Now, we know in -14 into g(x) and solve.
g(-14)=(-14)-8 [subtract]
g(-14)=-22
Now, we know that g(f(-1))=-22.
a researcher is studying a group of field mice. the distribution of the weight of field mice is approximately normal with mean 25 grams and standard deviation 4 grams. which of the following is closest to the proportion of field mice with a weight greater than 33 grams?
a)0.046
b)0.977
c)0.954
d)0.023
Answers
Using the normal distribution, it is found that the proportion is closest to 0.023, given by option d.
---------------------------------
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
---------------------------------
Mean of 25 means that [tex]\mu = 25[/tex]Standard deviation of 4 means that [tex]\sigma = 4[/tex].The proportion above 33 is 1 subtracted by the p-value of Z when X = 33, thus:[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{33 - 25}{4}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a p-value of 0.977.
1 - 0.977 = 0.023
Thus the proportion is 0.023, given by option d.
