Answer:

13,440

Step-by-step explanation:

10 possible digits 0 - 9

5 possible numbers for position 5  (odd digits only)

8 possible numbers for position 1  (cannot be zero or the odd number selected for position 5)

8 possible numbers remain for position 2 (10 minus 2 already selected)

7 possible numbers remain for position 3 (10 minus 3 already selected)

6 possible numbers remain for position 4 (10 minus 4 already selected)

5•8•8•7•6 = 13,440

What is the value of the function at x = 2?<br> Enter your answer in the box.
Vedmedyk [2.9K]
Check the graph and observe where x = 2.

And check where it cuts across the line of the graph.

If you trace the graph carefully, when x = 2, y = -2

So the value of the function is -2.  

I hope this helps.

The nth term of a sequence is 3n + 2
gavmur [86]

Answer:

see explanation

Step-by-step explanation:

To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term rule

a_{1} = (3 × 1) + 2 = 3 + 2 = 5

a_{2} = (3 × 2) + 2 = 6 + 2 = 8

a_{3} = (3 × 3) + 2 = 9 + 2 = 11

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

substitute n = 10 into the n th term rule

a_{10} = (3 × 10) + 2 = 30 + 2 = 32

A manufacturer of shipping boxes has a box shaped like a cube. The side length is

The vol. of a cube of side length s is V=s^3.

So, if the side length is 5a+4b, then the volume of the cube is

V(a, b) = (5a+4b)^3.  This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
