9-19 can somebody explain how to do one of them (not the answer) but how to work them out and the answer

Jet001 [13]

Answer: I’ll give you an example of how to do it by solving number 9 - h^2 + 8h + 16

Step-by-step explanation:

Step 1: Find two numbers that when you multiply them it gives you the first term’s coefficient multiplied by the last term’s coefficient (1x16 = 16) and when you add them it gives you the second term’s coefficient (8). The numbers in this case are positive 4 and positive 4.

Step 2: Create two parenthesis with the letter accompanied by the numbers. (h + 4)•(h+4). And that’s how you factor.

In case the first term is elevated to the third you will have to take out GCF (greatest common factor) first. If the numbers are too high like in the exercise number 15 you can also take out GCF and it will make it a lot easier to solve. Sometimes what you write on the parenthesis in the step 2 can be simplified, if that’s so then you would have to do it in order to get the correct answer.

Hope this helps you.

A car sells for $20,930. If the rate of depreciation is 6%, what is the value of the car after 8 years? Round to the nearest tho

Verizon [17]

Answer: 10,883.6

Step-by-step explanation: So first we have to find out what the depreciation is and to find that we have to take the 20,930 and times it by 0.06 (6%) which is 1,255.8,

So, we then times 1,255.8 by 8 because 8 years of depreciation, which is 10,046.4,

Finally we take 20,930 (the cars total value) and subtract the depreciation from it (10,046.4) so in 8 years the car is worth 10,883.6

320 or 360 which is closer to 344?

Crank

All we need to do is subtract each number by 344 and see which number is the lowest

344 - 320 = 24

360 - 344 = 16

Therefore, 360 is closest to 344

Hope this helps

What is the first quartile of this data set? 11, 12, 15, 16, 17, 19, 22, 24, 29, 33, 38

Bas_tet [7]

Answer:

Answer:

first quartile of this data set is 13

Step-by-step explanation:

11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38

First we find the median for the given set of numbers

Median is the middle number

11, 12, 13, 15, 17, 19, 22, 24, 29, 33, 38

19 is the median of the set of numbers

First quartile is the median of the set of numbers below 19

third quartile is the median of the set of number above 19

11, 12, 13, 15, 17

Median of 11, 12, 13, 15, 17 is 13

So first quartile of this data set is 13
