Answer:

A) f^-1(x)=(x-8)^3+2

Step-by-step explanation:

To find the function inverse, switch the x with y and solve for y.

y=\sqrt[3]{x-2}+8 \\\\x=\sqrt[3]{y-2}+8\\\\(x-8)^3 = y-2\\\\ (x-8)^3 + 2 = y

Please help with this don’t understand please help with answers!
Papessa [141]

Answer:

  see attachment

Step-by-step explanation:

The directions tell you what you need to know. It is a matter of adding up the values shown and finding the missing number to make the total be -20. Of course, it works best to start with a row, column, or diagonal that has 4 numbers already.Then, you're only finding the 5th number.

You can start with either diagonal, column 1 or 4, and row 4 or 5. Filling the missing numbers in those spots (red) will let you find the remaining missing numbers (green, then blue).

The square at row 2, column 2 can be filled on the first round using the down-right diagonal. I have shown it as filled on the second round after row 5 column 2 is filled.

Using a spreadsheet can make this easier, because you can write formulas for the sums in each row, column, and diagonal. Then you're just making those sums be -20.

___

For example, consider the up-right diagonal. The sum of the given values, -6, 0, -4, -2, is -12. Then the spot at row 1, column 5 must be filled with -8 to make the sum be -20.

Please help, I don't understand part a or b.
Serggg [28]
Part A
25-9=16
16/2=8
The length of the rope holding the top right corner of the banner to the post is 8 feet long

Part B
13-9-2= 2 for width
25-8=16 16/2=8 for length 
Use the Pythagorean Theorem 
a^{2}+b^{2}=c^{2}
8^{2}+ 2^{2}= c^{2}
64+4=c^{2}
68=c^{2}
\sqrt{68}=  \sqrt{c}
34=c
The length of the rope from the bottom right corner of the banner to the post is 34 feet
