Answer:

SA = 967.6 cm²

Step-by-step explanation:

Surface Area of cylinder = $2\pi r h + 2\pi r^2$

<u><em>Where r = 7 cm, h = 15 cm</em></u>

=> SA = 2(3.14)(7)(15)+2(3.14)(7)²

=> SA = 659.7 + 2(3.14)(49)

=> SA = 659.7 + 307.9

=> SA = 967.6 cm²

How do I graph the parabola?

scoundrel [369]

First of all, find a program or a calculator that will give you the answer. Then you'll know how to make your table. I recommend Desmos. I have inserted the final graph for you.

Make up a table for this graph. Put the lowest point as the central entry in your graph.

x y
-4
-3
-2
-1
0
Now fill in the y values.

x y
-4 1
-3 -3.5
-2 -5
-1 -3.5
0 1

You can use the outline of the parabola and then mark the outline with the points in the table.

Each year the population declines to 15%
Then they put back 500 fish in the lake.

The equation: (1000 * .85) +500

Help please my teacher isn't the greatest.

Answer:

x = 9.5

Step-by-step explanation:

We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:

3x - 6 + x + 2 = 34

4x - 6 + 2 = 34

4x - 4 = 34

4x = 38
