Answer:  a)  x ≈ 7.39

<u>Step-by-step explanation:</u>

6+ln\ x=8\\\\\\\text{Subtract 6 from both sides:}\\ln\ x=2\\\\\\\text{Apply e to both sides:}\\e^{ln\ x}=e^2\\\\\\\text{Cancel out }e^{ln}:\\x=e^2\\\\\\\text{Use a calculator to find the value of }e^2:\\x\approx7.389\\\\\\\text{Rounded to the nearest hundredth:}\\\large\boxed{x\approx 7.39}

Suppose that x and y vary inversely and that y=1/6 when x=3. Write a function that models the inverse variation and find y when
juin [17]

Answer:

The Inverse variation states a relationship between the two variable in which the product is constant.

i.e x \propto \frac{1}{y}

then the equation is of the form: xy = k where k is the constant of variation.

As per the given information: It is given that x and y  vary inversely and that y = 1/6 when x = 3.

then, by definition of inverse variation;

xy = k                                      ......[1]

Substitute the given values we have;

3 \cdot \frac{1}{6} = k

\frac{1}{2} = k

Now, find the value of y when x = 10.

Substitute the given values of x=10 and k = 1/2, in [1] we have;

10y = \frac{1}{2}

Divide both sides by 10 we get;

y = \frac{1}{20}

therefore, a function that models the inverse variation is; xy = \frac{1}{2} and value of  y = \frac{1}{20} when x = 10.

Since we have the length and width of the window, we can multiply the two values.

Convert both fractions to improper fractions

(26/3)*(23/4)

=598/12 ft squared

= This simplifies to 49 5/6 ft. squared

On July 1, Black Corporation had 200,000 shares of $10 par common stock outstanding. The market price of the stock was $12 per s
Yakvenalex [24]

Answer:

$4000000

Step-by-step explanation:

Given data :

200000 shares at $10 par common stock outstanding

market price of stock = $12 per share

increased par value of stock = $10 ( $20)

Black's paid-in capital--excess of par account = $4000000.

The balance in Black's paid-in capital--excess of par account immediately after the reverse stock spit will be $4000000 because the increased par value of stock from $10 to $20 will be reversed back immediately after the reverse stock hence the paid-in capital--excess before stock split = paid-in capital --excess immediately after reverse stock split

Choose the graph which represents -6x - 5y = -10
Anna007 [38]

Answer:

y = 2 + ((-)6/5)x

Step-by-step explanation:

-6x-5y=-10

add 6x to both sides.

-5y = -10 +6x

divide both sides by -5

y = 2 - (6/5)x

Plug in 0 for x to get the y intercept:

f(0) = 2 - (6/5) (0)

y = 2

(0, 2) is the y intercept.

Do the same for values such as -1, -2, 1, and 2, etc.

Then graph it.
