Answer:
See below.
Step-by-step explanation:
I've never seen one asked quite this way, but I think I have it figured out.
The objective here is to get the right answer for each square. The answer is either the one next to the 'x', which means you put an 'x' in the tic-tac-toe square or the answer is the one next to the 'O', which means you put an 'O' in the tic-tac-toe square.
I will number them boxes 1-3 on the top row, 4-6 for the next, and 7-9 for the bottom row.
Box 1: In a fraction, you subtract the bottom exponent from the top exponent, so the proper exponent is 10 - 2 = 8. That is an O for g^8.
Box 2: A power raised to a power - multiply the exponents. 2*6=12. That is an X for m^12 for box 2.
Box 3: for multiplying the same base, you add the exponents. 4+5=9. That gives us y^9, which is a X for box 3.
Box 4: j is a factor four times, so that is j^4. That puts an O in Box 4.
Box 5: In a fraction, you subtract the bottom exponent from the top exponent, so we get -2 - (-6) = -2 + 6 = 4. The correct expression is h^4, so we have an X for box 5.
Box 6: A power to a power, you multiply the exponents so the first part becomes m^8. Now we have m^8 * m^5. For multiplying the same base, you add the exponents. 8+5=13. That gives us m^13, which puts an O in box 6.
Box 7: The top is a power to a power so we multiply the exponents. 4*5=20. The top is b^20.
On the bottom, for multiplying the same base, you add the exponents. 2+3=5, so the bottom is b^5.
Now we have a fraction, (b^20)/(b^5). In a fraction, you subtract the bottom exponent from the top exponent, so we have 20 - 5 = 15, and thus b^15. That gives us an X for box 7.
Box 8: A fraction IS a division, so we do divisons and fractions the same way. The p^3 on the left is the top (numerator) and the p^2 part is the bottom (denominator). So 3-2=1. But P^1 is just P, so we have an O for box 8.
Box 9: For the numerator, it is a power to a power so we multiply the exponents and get k^12.
For the denominator, we are multiplying the same base, so you add the exponents. 7 + (-5) = 2, and we get k^2 for the denominator
Now we have the fraction of k^12 OVER k^2. In a fraction, you subtract the bottom exponent from the top exponent. 12-2=10. We get k^10, giving us an X for box 9.
So here is what we get for tic-tac-toe.
0 X X
O X 0
X O X
We get 3 in a row in boxes 3, 5, and 7. The exponents in those problems are 9, 4, and 15 respectively. The product of thse 3 numbers is 540.
This was a LOT of steps, so I encourage you to check every little multiplication and addition I did.
Hope this helps.

You can use the fact that is irrational to answer the questions below. You can also use other facts proven within this exercise. (a) Prove that is irrational. (b) Prove that is irrational. (c) Is it true that the sum of two positive irrational numbers is also irrational
Answer:
See Explanation for proofs
Step-by-step explanation:
Given
See attachment for complete question
Solving (a):
[tex]\frac{\sqrt{2}}{2}[/tex] is irrational
[tex]\sqrt{2} =1.41421356237.....[/tex]
So, we have:
[tex]\frac{\sqrt{2}}{2} = \frac{1.41421356237.....}{2}[/tex]
[tex]\frac{\sqrt{2}}{2} = 0.70710678118....[/tex]
[tex]0.70710678118....[/tex] can not be represented as a fraction of whole numbers.
Hence:
[tex]\frac{\sqrt{2}}{2}[/tex] is irrational
Solving (b):
[tex]\sqrt{2} -2[/tex] is irrational
[tex]\sqrt{2} =1.41421356237.....[/tex]
So, we have:
[tex]\sqrt{2} -2 = 1.41421356237..... - 2[/tex]
[tex]\sqrt{2} -2 = -0.58578643763.....[/tex]
[tex]-0.58578643763.....[/tex] can not be represented as a fraction of whole numbers.
Hence:
[tex]\sqrt{2} -2[/tex] is irrational
Solving (c):
The sum of two positive irrational number is always irrational
Proof Below
If a is irrational and b is also irrational,
then
[tex]a + b = irrational[/tex]
Take for instance:
[tex]a = \sqrt{2[/tex]
[tex]b = \sqrt{8[/tex]
[tex]a + b = \sqrt{2} + \sqrt{8[/tex]
[tex]a + b = \sqrt{2} + \sqrt{4*2[/tex]
[tex]a + b = \sqrt{2} + \sqrt{4}*\sqrt{2[/tex]
[tex]a + b = \sqrt{2} + 2\sqrt{2[/tex]
[tex]a + b = 3\sqrt{2[/tex]
[tex]3\sqrt{2[/tex] is irrational and this is true for the sum of every positive irrational numbers

A cuántos metros equivalen 92 kilómetros?
Answer:
92000
Step-by-step explanation:
Answer:
92,000
Step-by-step explanation:
1 km=1000 m
So 1 km×92= 92 km
But 1000 m×92= 92,000 m
Write the equation of the line that has m = -1/3 and goes through the point (-9, -1). Write the equation in slope-intercept form.
Step-by-step explanation:If you want to find the equation of line with a given a slope of -8 which goes through the point (6,9), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
y-y%5B1%5D=m%28x-x%5B1%5D%29 where m is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
y-9=%28-8%29%28x-6%29 Plug in m=-8, x%5B1%5D=6, and y%5B1%5D=9 (these values are given)
y-9=-8x%2B%28-8%29%28-6%29 Distribute -8
y-9=-8x%2B48 Multiply -8 and -6 to get 48
y=-8x%2B48%2B9 Add 9 to both sides to isolate y
y=-8x%2B57 Combine like terms 48 and 9 to get 57
------------------------------------------------------------------------------------------------------------
Answer:
So the equation of the line with a slope of -8 which goes through the point (6,9) is:
y=-8x%2B57 which is now in y=mx%2Bb form where the slope is m=-8 and the y-intercept is b=57

A force of 192 lb is required to hold a spring stretched 3 ft beyond its natural length. How much work W is done in stretching it from its natural length to 6 inches beyond its natural length
Answer:
The work done in stretching the spring is 8 lb.ft
Step-by-step explanation:
Given;
Applied force, F = 192 lb
extension of the spring, x = 3 ft
Determine the spring constant from the applied force and extension;
[tex]k = \frac{F}{x} \\\\k = \frac{192 \ lb}{3 \ ft} \\\\k = 64 \ lb/ft[/tex]
When the spring is stretched 6 inches beyond its natural length, the work done is calculated as follows;
x = 6 inches = 0.5 ft
[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} (64 \ lb/ft)(0.5 \ ft)^2\\\\W = 8 \ lb.ft[/tex]
Therefore, the work done in stretching the spring is 8 lb.ft

Seventy-two percent of the light aircraft that disappear while in flight in a certain country are subsequently discovered. Of the aircraft that are discovered, 66% have an emergency locator, whereas 80% of the aircraft not discovered do not have such a locator. Suppose a light aircraft has disappeared. (Round your answers to three decimal places.)
a) If it has an emergency locator, what is the probability that it will not be discovered?
b) If it does not have an emergency locator, what is the probability that it will be discovered?
c) If we consider 10 light aircraft that disappeared in flight with an emergency recorder, what is the probability that 7 of them are discovered?
Answer:
a) 0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.
b) 0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.
c) 0.064 = 6.4% probability that 7 of them are discovered.
Step-by-step explanation:
For itens a and b, we use conditional probability.
For item c, we use the binomial distribution along with the conditional probability.
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
a) If it has an emergency locator, what is the probability that it will not be discovered?
Event A: Has an emergency locator
Event B: Not located.
Probability of having an emergency locator:
66% of 72%(Are discovered).
20% of 100 - 72 = 28%(not discovered). So
[tex]P(A) = 0.66*0.72 + 0.2*0.28 = 0.5312[/tex]
Probability of having an emergency locator and not being discovered:
20% of 28%. So
[tex]P(A cap B) = 0.2*0.28 = 0.056[/tex]
Probability:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.056}{0.5312} = 0.105[/tex]
0.105 = 10.5% probability that it will not be discovered if it has an emergency locator.
b) If it does not have an emergency locator, what is the probability that it will be discovered?
Probability of not having an emergency locator:
0.5312 of having. So
[tex]P(A) = 1 - 0.5312 = 0.4688[/tex]
Probability of not having an emergency locator and being discovered:
34% of 72%. So
[tex]P(A \cap B) = 0.34*0.72 = 0.2448[/tex]
Probability:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2448}{0.4688} = 0.522[/tex]
0.522 = 52.2% probability that it will be discovered if it does not have an emergency locator.
c) If we consider 10 light aircraft that disappeared in flight with an emergency recorder, what is the probability that 7 of them are discovered?
p is the probability of being discovered with the emergency recorder:
0.5312 probability of having the emergency recorder.
Probability of having the emergency recorder and being located:
66% of 72%. So
[tex]P(A \cap B) = 0.66*0.72 = 0.4752[/tex]
Probability of being discovered, given that it has the emergency recorder:
[tex]p = P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.4752}{0.5312} = 0.8946[/tex]
This question asks for P(X = 7) when [tex]n = 10[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 7) = C_{10,7}.(0.8946)^{7}.(0.1054)^{3} = 0.064[/tex]
0.064 = 6.4% probability that 7 of them are discovered.
