You have a chess board as pictured, with squares numbered 1 through 64. You also have a huge change jar with an unlimited number
ANEK [815]

Answer:

(a) 512 dimes

(b)D(n) = 2^{n-1}

(c) 9.22337 x 10¹⁸ dimes

(d) 9.22337 x 10¹² km

(e) roughly 61,489.13 times longer than the distance from the earth to the sun.

Step-by-step explanation:

b. Starting with 1 dime in the first square, if the number of dimes per each square is the double of the previous square, the general equation for the number of dimes in each square 'n' can be found by:

D(1) = 1\\D(2) = 2^1\\D(3) = 2^2\\D(4) = 2^3\\D(n) = 2^{n-1}

a. On the 10th square:

D(10) = 2^{10-1}\\D(10) = 512\ dimes

c. On the 64th square:

D(64) = 2^{64-1}\\D(10) = 9.22337 *10^{18}\ dimes

d. If a dime is 1 mm thick, the 64th pile will be:

h= 9.22337*10^{18}*0.0001\ m\\h= 9.22337*10^{15}\ m\\h= 9.22337*10^{12}\ km

e. The ratio between the height of the last pile (h) to the distance from the earth to the sun is:

R=\frac{9.22337*10^{12}\ km}{150,000,000\ km}\\ R=61,489.13

The height of the last pile is roughly 61,489.13 times longer than the distance from the earth to the sun.

Which relation is not a function
KiRa [710]
By definition a function can have only one value of y for any given value of x.

Since B. contains both (-1,2) and (-1,0), y has two values for the same value of x and thus B. cannot be a function...

In the figure shown, what additional information is needed to show that △ABC≅△DEF by SSS?
alexgriva [62]

Answer:

Step-by-step explanation:

They're asking for what other information is needed.

We were given triangle ABC is congruent to triangle DEF. We know for certain line AB and line DC are congruent to each other as well as lines BC and EF.

The additional information we need to know is if line AC is congruent to line DF to absolutely be sure.

Remember SSS by definition is:  Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other. If all three sides in one triangle are the same length as the corresponding sides in the other, then the triangles are congruent.

Is 41/50 closer to 9/11 or 10/11? Verify your answer
Setler79 [48]
<span>Which one is closer to 41/50, 9/11 or 10/11
=> Let’s find the value of the two given choices to be able to fin which one is closer to 41/50
=> 9/11 convert this to decimal number
=> 9 divide by 11
=> 0.82

=> 10/11 convert in decimals
=> 10 divide by 11
=> 0.91

Now, we have the value of both numbers, let’s find the value of 41/50
=> 41/50
=> 41 divided by 50
=> 0.82

Thus, the closer number to 41/50 is the 9/11 because they both have 0.82 decimal value.
