c is correct answer is yes
Answer:
D) 12
Step-by-step explanation:
divide each term by -8 and simplify
-8/-8x=-96/-8
x=12
You did not include the questions, but I will give you two questions related with this same statement, and so you will learn how to work with it.
Also, you made a little (but important) typo.
The right equation for the annual income is: I = - 425x^2 + 45500 - 650000
1) Determine <span>the youngest age for which the average income of
a lawyer is $450,000
=> I = 450,000 = - 425x^2 + 45,500x - 650,000
=> 425x^2 - 45,000x + 650,000 + 450,000 = 0
=> 425x^2 - 45,000x + 1,100,000 = 0
You can use the quatratic equation to solve that equation:
x = [ 45,000 +/- √ { (45,000)^2 - 4(425)(1,100,000)} ] / (2*425)
x = 38.29 and x = 67.59
So, the youngest age is 38.29 years
2) Other question is what is the maximum average annual income a layer</span> can earn.
That means you have to find the maximum for the function - 425x^2 + 45500x - 650000
As you are in college you can use derivatives to find maxima or minima.
+> - 425*2 x + 45500 = 0
=> x = 45500 / 900 = 50.55
=> I = - 425 (50.55)^2 + 45500(50.55) - 650000 = 564,021. <--- maximum average annual income
Answer:
A. Auto Sum
Step-by-step explanation:
In a spread sheet, if there are so many entries in form of numbers, whether in form of row or a column, it might be a pain staking job to sum all them individually. In spread sheet, the best option is to perform auto sum option, which as shown by its name, will add up all the entries given and produce the answer.
Now in given options of the question, auto correct, auto summarize and auto format are not usable because all of these options will either summarize or provide average or perform formatting, as they are not mathematical functions since, Alexander wants to add up all the amount he lent to Niraj, which means a mathematical task, so auto sum, as a mathematical command is best option.
