Find (fog)(x) When F(x)=x^2-7x+12 And G(x)=3/x^2-16

Answers

Answer 1

Answer:

[tex]f( \frac{3}{ {x}^{2} - 16 } ) = ({\frac{3}{ {x}^{2} - 16 }})^{2} - 7(\frac{3}{ {x}^{2} - 16 }) + 12 \\ = \frac{9}{ {x}^{4} - 32 {x}^{2} + 256 } - \frac{21}{ {x}^{2} - 16} + 12[/tex]

Answer:

(8, 3)

Step-by-step explanation:

The first number (8) is our x, and we can see that this point is 8 units to the right. Then the second number (3) is our y, and we can see this is 3 as the point is 3 units up.

x = right or left

      - right = positve

      - left = negative

y = up or down

      - up = positve

      - down = negative

Answer:

B = (8, 3)

Step-by-step explanation:

In the ordered pair (x, y) of point B, (8, 3):

x = 8

y = 3

a scale drawing of Lafayette square is 8 inches long and 4 inches wide. The actual park is 160 feet wide. What is the actual area of the park, in square yards?

Answers

Answer:

Lafayette Square is about 5688.89 square yards  

Step-by-step explanation:

The scale factor( ratio between the two sides) is 8 inches long to 4 inches wide or 2 to 1;  2 inches to one 1

Given the actual park is 160 feet wide ( need this measurement in inches).

so the actual part is 160 · 12 = 1920 inches wide.

Using the ratio long/ wide = long/ wide 2/1 = ?/1920.  The part is 3840 inches long.

Answer need to be in yards:  divide by 36 because 36 inches = 1 yard.

Long = 3840/36 = 320/3 yards

wide = 1920/36 = 160/3 yards

Actual area = L · W

                   = (320/3)·(160/3)

                   = 51200/9

                    = 5688.89 square yards

Noah and Amelia are reading the same book. At the beginning of the month, Noah was on page 41 and Amelia was on page 13. Noah will read 12 pages per day and Amelia will read 16 pages per day. Let NN represent the page of the book that Noah is on at the end of tt days into the month, and let AA represent the page of the book that Amelia is on at the end of tt days into the month. Write an equation for each situation, in terms of t,t, and determine whether Noah or Amelia is farther along in the book after 3 days.

Answers

Answer:

After 3 days, Noah is still farther along reading.

Step-by-step explanation:

Here are the two equations:

NN = 12tt + 41

AA = 16tt + 13

Now we plug in 3 to both equations to see what page they're on after 3 days:

[tex]NN = 12(3) + 41\\NN = 36 + 41\\NN = 77 \\\\AA = 16(3) + 13\\AA = 48 + 13\\AA = 61[/tex]

After 3 days, Noah is 77 pages along and Amelia is 61 pages along.

77 pages > 61 pages so therefore Noah is still farther along.
