Answer:

27.2mm²

Step-by-step explanation:

Area of a triangle = \frac{1}{2} * base * height

Base of this triangle = 8mm

Height = 6.8mm

Area = \frac{1}{2} * 8mm * 6.8mm

       = 4mm * 6.8mm

       = 27.2mm²

Is 4-heap Nim with heaps of sizes 22, 19, 14, and 11 balanced or unbalanced? Player I's first move is to remove 6 coins from the
nadya68 [22]

Answer:

Player II should remove 14 coins from the heap of size 22.

Step-by-step explanation:

To properly answer this this question, we need to understand the principle and what it is exactly is being asked.

This question revolves round a game of Nim

What is a game of Nim: This is a strategic mathematical game whereby,  two opposing sides or opponent take turns taking away objects from a load or piles. On each turn, a player remove at least an object and may remove any number of objects provided they all come from the same heap/pile.

Now, referring back to the question, we should first understand that:

                        22₂ = 1 0 1 1 0

                         19₂= 1 0 0 1 1

                         14₂= 0 1 1 1 0

                          11₂= 0 1 0 1 1

and also that the “bit sums” are all even, so this is a balanced game.

However, after Player I removes 6 coins from the heap of size 19, Player II should remove 14 coins from the heap of size 22.

Tina bought a painting while on vacation in 2009. The table below shows the value of the painting in2009,2010,and2011. If this t
otez555 [7]

Answer:

The answer is E

Step-by-step explanation:

We first are going to look at our first term on the table(the number that comes up first) which is $75.

Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).

<em>Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation.   </em>

<em>We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!</em>

<em>Equation: </em><em>   F(x)= 75(1.18) ^21 </em>

<em>The answer that you get is:    $2424.28</em>
