The number of significant figures in 261 g is 3 and the number of significant figures in the answer 0.261 kg is also 3.
b. 3 days to seconds
1 day = 24 hours, 1 hour = 60 minutes, 1 minute = 60 seconds
1 day = 24 x 60 x 60 seconds
Therefore, 3 days = 3 x 24 x 60 x 60 seconds = 2, 59, 200 seconds
Since, the number of significant figures in 3 days is 1, hence we write 2, 59, 200 as 300000 seconds, such that it has 1 significant figure.
c. 9, 474 mm to cm
For converting mm to cm, we divide by 10
(9474 / 10) = 947.4 cm
The number of significant figures in 9, 474 mm is 4 and the number of significant figures in the answer 947.4 cm is also 4.
d. 0.73 KL to L
1 KL = 1000 L
0.73 KL = 0.73 X 1000 L = 730 L

when calculating the percent of pitches thrown at least 92 mph, why did we have to subtract from 100%?
When calculating the percent of pitches thrown at least 92 mph, we subtract from 100% to find the percentage of pitches that fall within a certain threshold (in this case, 92 mph).
When calculating the percentage of pitches thrown at a certain speed, say 92 mph, we use 100% as a reference point. 100% means all of the pitches. By subtracting the percentage of pitches thrown below 92 mph from 100%, we find the percentage of pitches that were thrown at 92 mph or above. This helps us understand what proportion of pitches were thrown at this speed or higher, compared to the total number of pitches thrown. By doing this, we can see how many pitches fall within a certain threshold, in this case 92 mph or above.

When a car is randomly selected and weighed it is found to weigh 1628.3 kg.
a. A discrete data set because there are infinitely many possible values
b. A discrete data set because the possible values can be counted
c. A continous data set because the possible values can be counted
d. A continous data set because there are infinitely many possible values
The value given is from a continuous data set because there are infinitely many possible values.
In statistics, a discrete data set is a set of data that can only take certain values, typically whole numbers, that can be counted. A continuous data set is a set of data that can take any value within a certain range, and the values can't be counted as they are infinite in number.
In the given scenario, the weight of a car can take any value within a certain range, and there are infinitely many possible values between any two values. For example, between 1628.3 kg and 1628.4 kg, the car's weight could be an infinite number of values. Hence, the weight of the car is a continuous variable, and the given value of 1628.3 kg is part of a continuous data set.
Hence, the correct answer is d.

Use the sum of cubes identity to find the factors of the expression 8x^6 + 27y^3. Write your answer in the form of the expression on the right of the sum of cubes identity.
The sum of cubes identity states that a^3 + b^3 = (a+b)(a^2 - ab + b^2). To find the factors of 8x^6 + 27y^3, we can apply this identity to the expression by identifying a and b:
What is the identity of the sum of cubes?
What Does the Algebraic Sum of Cubes Formula Mean? One of the key algebraic identities is the sum of cubes formula. Its symbol is written as a3 + b3 and is interpreted as a cube plus a cube. A3 + b3 = (a + b) (a2 - ab + b2) is how the sum of cubes formula (a3 + b3) is written.
8x^6 + 27y^3 = (2x^2)^3 + (3y)^3
We can then apply the identity to get:
(2x^2)^3 + (3y)^3 = (2x^2 + 3y)((2x^2)^2 - 2x^2*3y + (3y)^2)
This gives us the factors of 8x^6 + 27y^3 as (2x^2 + 3y)(4x^4 - 6x^2y^2 + 9y^2).

Answer:
1/2
Step-by-step explanation:
So the point of this question is to compare all of the answers and see which one fits best. To do this, first change the denominator to match 5/8. To convert 1/2 into eighths, multiply 2 by 4 so you get eight. Since you did that, you have to do the same to the numerator. Therefore:
1/2 = 4/8
Is 4/8 less than 5/8? Yes. Is it greater than 1/9? Yes, but how? Do the same thing but instead convert 1/2 into ninths. Multiple 2 by 4.5 to get 9 and 1 by 4.5 to get 4.5.
1/2 = 4.5/9
4.5/9 is greater than 1/9, so you answer would be 1/2.
Normally you would test every answer, but to save time I'll just stop there because the first option was correct. I hope you understand. :)
Answer:
1/2
Step-by-step explanation:
1/2 = 4/8 which is less than 5/8.
1/9 = 2/18
1/2 = 9/18 which is greater than 2/18 (same as 1/9)
the fourteen digits of an account number are to be written, one per unit square, in the string of unit squares below. the sum of any three consecutive digits is 15. what is the value of x?
The value of x is 4 which means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on.
This problem is asking for the value of x in a sequence of 14 digits where the sum of any three consecutive digits is equal to 15. To solve for x, we can use the information provided and basic algebra.
Let's assign a variable to each of the 14 digits in the sequence. For example, let x be the first digit, (x + 1) be the second digit, (x + 2) be the third digit, and so on. Then, the sum of any three consecutive digits must equal 15:
x + (x + 1) + (x + 2) = 15
Expanding and solving for x, we get:
3x + 3 = 15
3x = 12
x = 4
So, the value of x is 4. This means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on. By continuing this pattern, we can fill in the entire sequence of 14 digits such that the sum of any three consecutive digits is equal to 15.

Step-by-step explanation:
The expression [4x4(2x3)]2 means to square the result of the expression inside the brackets.
4x4 = 16x4
2x3 = 6x3
So, [4x4(2x3)] = [16x4(6x3)] = 96x7.
Squaring this result, we get
[4x4(2x3)]2 = 96x7 * 96x7 = (96 * 96)x(7 * 7) = 9216x49 = 9216x^49.
Therefore, the expression [4x4(2x3)]2 is equivalent to 64x49, x, 49.

1. The equation is z^{16} = -1 - i.
We have express our answer in the form of
[tex]\; z = re^{i\theta }[/tex]
When we enter it into the first equation, we obtain,
[tex]r^{16}e^{16i\theta }=-1-i\; \; \; \; \; \; \; \; \; \; \; \;[/tex]--(2)
Using the modulus of both sides, we obtain,
[tex]\left |r^{16} \right |\: \: \left | e^{16i\theta } \right |=\sqrt{\left ( -1 \right )^{2}+\left ( -1 \right )^{2}}[/tex]
Simplifying
[tex]\; \; \; \; \; r^{16}=\sqrt{2}[/tex]
Taking root of 16 on both side, we get
[tex]r=2^{1/32}[/tex]
Plugging this value of 'r' back in equation (2), we get,
[tex]\sqrt{2}\; \; e^{16i\theta }=-1-i[/tex]
Divide by √2 on both side, we get
[tex]e^{16i\theta }=-\frac{1}{\sqrt{2}}-\frac{1}{\sqrt{2}}i[/tex]
We can write [tex]e^{16i\theta }[/tex] as
[tex]\; \; \; \;cos16\theta +isin16\theta =-\frac{1}{\sqrt{2}}-\frac{1}{\sqrt{2}}i[/tex]
On comparing, we get
[tex]\; \; \; \;cos16\theta=-\frac{1}{\sqrt{2}}\;, \; \; \; \; \; \; \; sin16\theta =-\frac{1}{\sqrt{2}}[/tex]
Angle must therefore be in the third quadrant.
[tex]16\theta=\pi +\frac{\pi }{4}=\frac{5\pi }{4}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;16\theta=\frac{5\pi }{4}+2\pi =\frac{13\pi }{4}[/tex]
[tex]\theta=\frac{5\pi }{64}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;\theta=\frac{13\pi }{64}[/tex]
So, second smallest positive argument = 13π/64.
2) The equation is [tex]z^{13} = -1 +\sqrt{3i}[/tex].
We have express our answer in the form of
[tex]\; z = re^{i\theta }[/tex]
When we enter it into the first equation, we obtain,
[tex]r^{13}e^{13i\theta }=-1+\sqrt{3}i\; \; \; \; \; \; \; \; \; \; \; \;[/tex]
Using the modulus of both sides, we obtain,
[tex]\left |r^{13} \right |\: \: \left | e^{13i\theta } \right |=\sqrt{\left ( -1 \right )^{2}+\left ( \sqrt{3} \right )^{2}}[/tex]
Simplifying
[tex]r^{13}=2[/tex]
Taking root of 13 on both side, we get
[tex]r=2^{1/13}[/tex]
Reintroducing this 'r' value into the equation from [tex]r^{13}e^{13i\theta }=-1+\sqrt{3}[/tex], we get,
[tex]2e^{13i\theta }=-1+\sqrt{3}i[/tex]
Divide 2 on both side, we get
[tex]e^{13i\theta }=-\frac{1}{2}+\frac{\sqrt{3}}{2}i[/tex]
We can write [tex]e^{13i\theta }[/tex] as
[tex]\; \; \; \;cos13\theta +isin13\theta =-\frac{1}{2}+\frac{\sqrt{3}}{2}i[/tex]
[tex]\; \; \; \;cos13\theta=-\frac{1}{2}\;, \; \; \; \; \; \; \; sin13\theta =\frac{\sqrt{3}}{2}[/tex]
Angle must therefore be in the second quadrant.
[tex]13\theta=\pi -\frac{\pi }{3}=\frac{2\pi }{3}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;13\theta=\frac{2\pi }{3}+2\pi =\frac{8\pi }{3}[/tex]
[tex]\theta=\frac{2\pi }{39}\; \; \; \; \; \; \; \; ,\; \; \; \; \; \; \; \;\theta=\frac{8\pi }{39}[/tex]

What is the Alternate Interior Angles Theorem?The Alternate Interior Angles Theorem states that when two parallel lines are intersected by a transversal (a line that intersects two or more other lines), the pairs of alternate interior angles formed are congruent.
In other words, if you have two parallel lines and a transversal intersecting them, and you draw a line segment connecting two nonadjacent interior angles on opposite sides of the transversal, then those two angles will be congruent. This is because they are alternate (they are on opposite sides of the transversal and between the parallel lines) and interior (they are inside the parallel lines).
Therefore, the theorem the paragraph proof offers is: Alternate Interior Angles Theorem.

mercedes is running a special in which all SUVs are marked down for 15%. Mr. Estes purchased a G wagon for 160,000. What did he pay for the SUV after the discount was applied?
A.110,000
B.105,000
C.136,000
D. 125,000
The required payment for the SUV after the discount was applied is 136,000. Option C is correct.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
All SUVs are marked down by 15%.
Cost of G wagon = 160, 000
Cost after discount = 160000 - 15% of 160,000
= 136000
Thus, the required payment for the SUV after the discount was applied is 136,000. Option C is correct.

Abag of cat treats has 170 individual treats inside. My cat can eat 5 treats per day. What is the rate of change? How many treats are left in the bag after 20 days?
The rate of change is -5.
The number of treat left in the bag after 20 dyas is 70.
How to find rate of change?A bag of cat treats has 170 individual treats inside. Your cat can eat 5 treats per day. Therefore, the rate of change can be calculated as follows:
The rate of change is the rate at which one quantity is changing with respect to another quantity.
Therefore, using equation
y = mx + b
where
m = slope = rate of changeb = y-interceptTherefore,
y = 170 - 5x
where
y = treat left in the bagx = number of daysHence,
rate of change = -5
Let's find the treat left in the bag after 20 days
y = 170 - 5x
y = 170 - 5(20)
y = 170 - 100
y = 70
Therefore, 70 treat is left in the bag.

write the formal negation of the following statements. your negation must not contain any explicit negation symbols. (a) (2 points) ∀x∃y(2 < x ≤y) (b) (2 points) ∀y∃x(y > 0 →x ≤0)
The negation of the statement ∀x∃y(2 < x ≤y) is ∃x∀y(x ≤2 ∨ y < x) and the negation of the statement ∀y∃x(y > 0 →x ≤0) is ∃y∀x(y ≤0 ∨ 0 < x).
(a) ∃x∀y(x ≤ 2 ∨ y < x)
This statement can be read as: There exists an x such that for all y, x is less than or equal to 2 or y is less than x. To calculate this, we can look at the inequalities in both directions. We know that x is greater than 2, so we can use this to determine the lower bound for y. To prove this, we can examine the case when x = 2 and y = 3. Since 3 is greater than 2, the statement is true.
(b) ∃y∀x(y ≤ 0 ∨ x > 0)
This statement can be read as: There exists a y such that for all x, y is less than or equal to 0 or x is greater than 0.
This statement states that there exists a y such that for all x, either y is less than or equal to 0 or x is greater than 0. To calculate this, we can look at the inequalities in both directionsTo prove this, we can examine the case when y = -1 and x = 1. Since 1 is greater than 0, the statement is true.

(1 point) if (1)=−2, (5)=−7, and ∫51()=−8, evaluate the integral ∫51′().
Combining the given information, ∫51′() = f(5) - f(1) = -7 - (-2) = -5. , the integral of ∫51′() is equal to -5.
In order to evaluate the integral ∫51′(), we need to use the Fundamental Theorem of Calculus. The Fundamental Theorem of Calculus states that the integral of a function's derivative is equal to the function value evaluated from one point to another. For example, if f'(x) is the derivative of a function f(x), then the integral of f'(x) from x = a to x = b is equal to f(b) - f(a).
Using the given information, we can solve the integral ∫51′() as follows. We know that the derivative of our function is 1, so the integral of 1 from x = 1 to x = 5 is equal to f(5) - f(1). Therefore, combining the given information, ∫51′() = f(5) - f(1) = -7 - (-2) = -5. Therefore, the integral of ∫51′() is equal to -5.
