A sequence is defined by the formula f(n+1)=f(n)-3. If f(4)=22, what is f(1)?

Mathematics

Answer:

Since f(n + 1) = f(n) - 3, we can also say that f(n - 1) = f(n) + 3.

By which we can say f(n - 3) = f(n) + 9

Since f(4) is 22, then f(1) must be 22 + 9, or 31.

For which operations is the set {0, 1} closed?

0 × <span>0 = 0
0 </span>× <span>1 = 0
1 </span>× <span>1 = 1

Which means multiplication is closed under {0, 1}

</span><span>1 </span>÷ <span>1 = 1
0 </span>÷ <span>1 = 0

Division is not closed under {0, 1}

1 + 1 = 2

Addition is not closed under {0, 1}

0 - 1 = -1

Subtraction is not closed under {0, 1} either



So it's only A. Multiplication which is closed under {0, 1}

Find the volume. Help asap. Please.
alexgriva [62]

Use the Pythagorean theorem to find the diameter:

Diameter = √(19.3^2 - 9.5^2)

Diameter = √(372.49 - 90.25)

Diameter = √282.24

Diameter = 16.8 m

Volume of a cylinder = PI x r^2 x h

r = 1/2 diameter = 16.8 /2 = 8.4

h = 9.5 m

Volume = PI x 8.4^2 x 9.5

= PI x 70.56 x 9.5

= PI x 670.32

In terms of PI volume = 670.32PI

As a decimal:

670.32 x 3.14 = 2104.8048 = 2100m^3 ( rounded to the nearest hundred)

If a plane crashes on the border of Mexico and the U.S, where would you bury the survivors by the law?
lyudmila [28]

Answer:

Step-by-step explanation:

So, since when do we start burying survivors alive? Did they crash into Zombiland? Was it Spirit Air who didn’t want to pay damages in law suits? Or is this a time distance question in which we have to wait until each of the surviving passengers pass away? If so then I suspect that those who survived the New Mexico/Texas border crash would be buried in the state or country in which they eventually died or where they so instructed their next of kin to bury them. Of course, maybe they would be cremated and then the ashes will sit on someone’s mantel until a house cleaner tosses them out or they ashes may be spread out over a special parcel of land or water.
