Hello,

f(x)=(Ln(x))²

f'(x)=2Ln(x)*1/x=2Ln(x)/x

f''(x)=2(1/x*x-Ln(x)*(-1/x²))/x²=2/x²+2*Ln(x)/x^4

f'(√e)=2/e+2/e²=2(e+1)/e²=1,006429....

Base on your question where as the function of f(x) is equals to (ln x) to the power of 2, then f"(sqrt of e) , based on my calculation, and the way i understand the function i came up with a formulation that could fit to find the answer to your question and the answer is <span>1,006, 429</span>

Homer and Bart plan to buy one computer for $499.00 strictly for gaming
kati45 [8]

Answer:

Part A: T(x) = $49.99x + $499.00

Part B: $748.95

Part C: T(x) = $49.99x + $24.99y + $499.00

Part D: $773.93

Step-by-step explanation:

Part A:

Let x represent the amount of games bought. Let T(x) represent total cost.

T(x) = $49.99x + $499.00

Part B:

T(x) = $49.99(5) + $499.00

T(x) = $249.95 + $499.00

T(x) = $748.95

Part C:

Let y represent the amount of controllers bought.

T(x) = $49.99x + $24.99y + $499.00

Part D:

T(x) = $49.99(4) + $24.99(3) + $499.00

T(x) = $199.96‬ + $74.97 + $499.00

T(x) = $773.93

The cash drawer of the market contains $227. There are six more $5 bills than $10 bills. The number of $1 bills is two more than
k0ka [10]

Answer:

There are 122 one dollar bills, 11 five dollar bills and 5 ten dollar bills.

Step-by-step explanation:

There are bills of one dollar, five dollars and ten dollars on the cash drawer, therefore the sum of all of them multiplied by their respective values must be equal to the total amount of money on the drawer. We will call the number of one dollar bills, five dollar bills and ten dollar bills, respectively "x","y" and "z", therefore we can create the following expression:

x + 5*y + 10*z = 227

We know that there are six more 5 dollar bills than 10 dollar bills and that the number of 1 dollar bills is two more than 24 times the number of 10 dollar bills, therefore:

y = z + 6\\x = 2 + 24*z

Applying these values on the first equation, we have:

2 + 24*z + 5*(z + 6) + 10*z = 227\\2 + 24*z + 5*z + 30 + 10*z = 227\\39*z + 32 = 227\\39*z = 227 - 32\\39*z = 195\\z = \frac{195}{39}\\z = 5

Applying z to the formulas of y and x, we have:

y = 5 + 6 = 11\\x = 2 + 24*5 = 122

There are 122 one dollar bills, 11 five dollar bills and 5 ten dollar bills.

Y=-2x graphed. had to put more words to put this out
timurjin [86]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))


slope=\frac{rise}{run}

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right


y = -2x

This has a y-intercept of 0, so the line intersects the y-axis/goes through the origin at (0,0)

The slope is -2 or \frac{-2}{1}, so from each point, you go down 2 units, and to the right 1 unit.
