No

Step-by-step explanation:

They are independent iff:

Answer:

Air pressure = [tex]4.6\frac{\text{lb}}{\text{in}^{2} }[/tex]

Step-by-step explanation:

Relationship between air pressure and altitude can be modeled by,

P = 14.7e[tex]14.7e^{-0.00004h}[/tex]

Where P = Air pressure

and h = altitude above the sea level

Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,

P = [tex]14.7e^{-0.00004\times 29028}[/tex]

  = [tex]14.7\times e^{-1.16112}[/tex]

  = 4.603

  ≈ 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Therefore, air pressure on Mount Everest = 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Complete question:

y = 2x² + 2x - 3

x = -2 -1 0 1 2

Answer:

Complete table of values

x:   -2        -1         0          1          2

y:    1          -3       -3          1         9

Step-by-step explanation:

Given;

y = 2x² + 2x - 3

To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.

when, x = -2

y = 2(-2)² + 2(-2) - 3

y = 8 - 4 - 3

y = 1

when x = -1

y = 2(-1)² + 2(-1) - 3

y = 2 - 2 - 3

y = -3

when x = 0

y = 2(0)² + 2(0) - 3

y = 0 - 0 - 3

y = -3

when x = 1

y = 2(1)² + 2(1) - 3

y = 2 + 2 - 3

y = 1

when x = 2

y = 2(2)² + 2(2) - 3

y = 8 + 4 - 3

y = 9

Complete table

x:   -2        -1         0          1          2

y:    1          -3       -3          1         9

=32000

32000 will be added per year

32000*5=160000 for 5 years

160000+50000=210000$

Answer:

18 inches

Step-by-step explanation:

Given: The heights of both cylinders are 48 inches and 32 inches. Diameter of the larger cylinder is 12 inches

To find: diameter of the larger cylinder

Solution:

Height of the larger cylinder (H) = 48 inches

Height of the smaller cylinder (h) = 32 inches

Diameter of the smaller cylinder (d) = 12 inches

Radius of the smaller cylinder (r) = d/2 =12/ 2= 6 inches

As two cylinders are similar, their heights and radii are proportional.

[tex]\frac{r}{h}=\frac{R}{H}\\\frac{6}{32}=\frac{R}{48}\\R=\frac{6}{32}\times 48=9\,\,inches[/tex]

Diameter of the larger cylinder = 2R = 2(9) = 18 inches

this is the answer

Answer:

27π

Step-by-step explanation:

First, find the area as though the circle were complete.

A = πr²

A = π(6)²

A = 36π

Now, if you look at the diagram, you can see that the chunk missing forms a 90 degree angle.  In a circle, there is 360 degrees in total.  This means that only 3/4 of the circle is left.  Multiply the area by 3/4.

36π × 3/4 = 27π

The area is 27π.

Answer:

Step-by-step explanation:

The matrix AB is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

-----------------------------------

This question is solved using multiplication of matrices.

To do this, we multiply the lines of the first matrix by the columns of the second.

-----------------------------------

In this question:

The first matrix is:

[tex]A =\left[\begin{array}{ccc}5&7&2\\4&-1&3\\6&8&-5\end{array}\right][/tex]

The second matrix is:

[tex]B = \left[\begin{array}{ccc}6&11&-4\\2&1&-5\\3&-9&6\end{array}\right][/tex]

------------------------------------

First line:

------------------------------------

Second line:

Second line of A by each column of B, so:

[tex]A_{2,1} = 4\times6 - 1\times 2 + 3\times3 = 31[/tex]

[tex]A_{2,2} = 4\times11 - 1\times 1 + 3\times (-9) = 16[/tex]

[tex]A_{2,3} = 4\times(-4) - 1\times (-5) + 3\times 6 = 7[/tex]

------------------------------------

Third line:

Third line of A by each column of B, so:

[tex]A_{3,1} = 6\times6 + 8\times 2 - 5\times3 = 37[/tex]

[tex]A_{3,2} = 6\times11 + 8\times 1 - 5\times (-9) = 119[/tex]

[tex]A_{3,3} = 6\times(-4) + 8\times (-5) - 5\times 6 = -94[/tex]

------------------------------------

Thus, the matrix is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

Answer:

c. Zhen spends 6 1/2 hours working per audiobook.

Step-by-step explanation:

The table below gives some completed audio lengths and the amount of time Zhen spends on the audiobook.

[tex]\left|\begin{array}{c|c}$Completed length of audiobook (hours) &$Working time (hours)\\---------&--------\\1&6\frac{1}{2} \\\\3\frac{1}{2}&22\frac{3}{4}\\\\7&45\frac{1}{2}\\\\10&65\end{array}\right|[/tex]

We observe that from the table, in 6.5 hours, Zhen completes 1 audiobook.

In fact, across the table:

[tex]\dfrac{6\frac{1}{2}}{1}=\dfrac{22\frac{3}{4}}{3\frac{1}{2}}=\dfrac{65}{10}=6\dfrac{1}{2} $ hour per audiobook[/tex]

Therefore, in this situation, 6.5 hours mean that Zhen spends 6.5 hours working per audiobook.

The correct option is C.

Answer:

  295 months

Step-by-step explanation:

You want to know the number of months required to pay off a 30-year loan of $125000 at 6% if an extra payment is made each year.

The number of payments required will depend on the actual payment schedule, and the way the lender computes interest due.

The attached calculation shows it takes 319 payments. The assumption is that they are evenly spaced at 13 payments per year (one every 4 weeks), and the interest is computed on the interval between payments.

If 13 payments are made per year, the number of years it takes to pay off the loan will be ...

  319/13 = 24 7/13

24 years and 7 months is 295 months.

__

Additional comment

If the first payment is made on Jan 28, and payments are made every 4 weeks, there will be 2 payments in Dec. That is, except for the last month of the year, there will be 1 payment per month.

If regular monthly payments are made, but one of the payments is doubled, the result may be different.

Answer:
