The average rate of change of g(x)=3x^2-5x from x=4 to x=8 is 90
How to determine the average rate of changeFrom the information given, we have that;
g(x) = 3x² - 5x
To determine the rate from x = 4 to x = 8
First, substitute the value of x as 4, we get;
g(4) = 3(4)² - 5(4)
expand the bracket, we get;
g(4) = 48 - 20
Subtract the values
g(4) = 28
For g(8), we get;
g(8) = 3(8)² - 5(8)
expand the bracket
g(8) = 192 -- 40
subtract the values
g(8) = 152
The average rate is;
= 152 + 28/2
= 90
Hence, the value is 90

whats 1+1?
please do answer!
Answer:
I thought it was 3, no wait its 2
Step-by-step explanation:
You are thinking of the Principia Mathematica, written by Alfred North Whitehead and Bertrand Russell. Here is a relevant excerpt:
Picture Below
As you can see, it ends with "From this proposition it will follow, when arithmetical addition has been defined, that 1+1=2." The theorem above, ∗54⋅43, is already a couple of hundred pages into the book (Wikipedia says 370 or so); the later theorem alluded to, that 1+1=2, appears in section ∗102, considerably farther on.
I wrote a blog article a few years ago that discusses this in some detail. You may want to skip the stuff at the beginning about the historical context of Principia Mathematica. But the main point of the article is to explain the theorem above.
The article explains the idiosyncratic and mostly obsolete notation that Principia Mathematica uses, and how the proof works. The theorem here is essentially that if α and β are disjoint sets with exactly one element each, then their union has exactly two elements. This is established based on very slightly simpler theorems, for example that if α is the set that contains x and nothing else, and β is the set that contains y and nothing else, then α∪β contains two elements if and only if x≠y.
The main reason that it takes so long to get to 1+1=2 is that Principia Mathematica starts from almost nothing, and works its way up in very tiny, incremental steps. The work of G. Peano shows that it's not hard to produce a useful set of axioms that can prove 1+1=2 much more easily than Whitehead and Russell do.

A trader makes a loss of 10% when he sells a watch for 15,300
what did it cost?
Answer:
CP = 17000
Step-by-step explanation:
Given that,
Loss = 10%
Selling price of the watch, SP = $15,300
We need to find the cost price of the watch.
[tex]CP=\dfrac{100}{100-L\%}\times SP\\\\CP=\dfrac{100}{100-10}\times 15300\\\\CP=17000[/tex]
So, the cost price of the watch is 17000.

HELP ASAP!! Mrs. Walsh is in search of a birthday gift for her niece and decided to shop at Kohls. Mrs. Walsh just had a nice shopping spree there, therefore she had $15 Kohls cash to use. She also had a friends and family coupon for 25% off the entire purchase. Mrs. Walsh made sure to search the fine print and there was nothing noted saying she cannot use BOTH coupons. Which coupon should Mrs. Walsh use first, or does it matter? Will this always be the case? How do you know? Show your work.
Answer:
The best answer would be the 25% off the entire purchase. Say for example Mrs. Walsh was willing to spend 100$ that would be 25% dollars she saved. But when it comes to save the most amount of money. If she spends under 60 dollars use the 15 dollars off. If it’s over 60 use the 25% off coupon
Breaking down Brown versus Whitman: Example 2 of the chapter 1 discusses an exit poll taken during the 2010 California gubernatorial election. The administrators of the poll also collected demographic data, which allows for further breakdown of the 3889 voters from whom information was collected. Of the 1633 voters registered as Democrats, 91% voted for Brown, with a margin of error of 1.4%. Of the 1206 voters registered as Republicans, 10% voted for Brown, with a margin of error of 1.7%. And of the 1050 Independent voters, 42% voted for Brown, with a margin of error of 3.0%.
Required:
a. Do these results summarize sample data or population data?
b. Identify a descriptive aspect of the results.
c. Identify an inferential aspect of the results.
Answer:
(A) Population data
(B) The figures
(C) The classification of votes by political party
Step-by-step explanation:
(A) These results summarize population data. The population is the total 3,889 voters from whom information was collected.
The samples would be
- Voters registered as Democrats (1,633)
- Voters registered as Republicans (1,206)
- Independent Voters (1,050)
The total of members in each sample equals the total number of people in the population.
(B) A descriptive aspect of the result is the figures or percentages. They describe how (in percentage) voters penned their votes for Brown and how they penned their votes for Whitman. NOTE: To get the percentage or fraction of those who voted for Whitman, simply subtract the percentage of Brown's supporters from a total of 100%.
(C) An inferential aspect of the results is the classification of votes by different parties (the samples are the different parties involved here). This helps to infer the sources of support for Brown and the sources of support for Whitman.
For example, if the total votes for Brown (in population result analysis) are low, the Republicans are the major reason why!
