Y=log x If y=10, then what is x?
-
10
-
1
-
100
-
10^2
Correct Answer
A. 10Explanation
The equation y = log x represents a logarithmic function where the base is implicitly 10. To find the value of x when y = 10, we need to express the equation in exponential form.
Since y = log₁₀x, then 10ʸ = x.
Substituting y = 10, we get 10¹⁰ = x.Rate this question:

What is 10*9*8*7*6*5*4*3*2*1?
-
10! or 3628800
-
100
-
1000
-
10^10
Correct Answer
A. 10! or 3628800Explanation
The given question is asking for the product of all the numbers from 1 to 10. This is represented by the factorial notation, which is denoted by an exclamation mark (!). Therefore, 10! means multiplying all the numbers from 1 to 10 together. In this case, 10! equals 3628800.Rate this question:

If 1/2x+1/2(1/2x+1/2(1/2x+1/2(1/2x+1/2...=y What does x equal?
-
2/4
-
1/2
-
1/4
-
1
Correct Answer
A. 1Explanation
The given equation represents an infinite geometric series with a common ratio of 1/2. To find the value of y, we can use the formula for the sum of an infinite geometric series: S = a / (1 - r), where S is the sum, a is the first term, and r is the common ratio. In this case, a = 1/2x and r = 1/2. Plugging these values into the formula, we get y = (1/2x) / (1 - 1/2) = (1/2x) / (1/2) = (1/2x) * (2/1) = 1/x. Therefore, y = 1/x. Since the answer is given as 1, we can conclude that x must equal 1.Rate this question:

What's the only place in this world who's Fahrenheit and Celsius degrees can be equal?
-
Alaska at -50 degrees
-
Antarctica at -40 degrees
-
Hawaii at 100 degrees
-
Anywhere that exceeds freezing point
Correct Answer
A. Antarctica at -40 degreesExplanation
Antarctica at -40 degrees is the only place in the world where Fahrenheit and Celsius degrees can be equal. This is because -40 degrees Fahrenheit is equal to -40 degrees Celsius. In all other options, the Fahrenheit and Celsius degrees are not equal.Rate this question:

What is the square root of 3 to the square root of 2 power times the square root of 3 to the negative square root of 2 power?
-
100
-
10
-
1
-
10^3
Correct Answer
A. 1Explanation
The given expression can be simplified as follows: square root of 3 to the square root of 2 power is equal to 3^(sqrt(2)). Similarly, square root of 3 to the negative square root of 2 power is equal to 3^(-sqrt(2)). Therefore, the given expression becomes 3^(sqrt(2)) * 3^(-sqrt(2)), which is equal to 3^(sqrt(2) - sqrt(2)). Since the exponent is zero, any number raised to the power of zero is equal to 1. Hence, the answer is 1.Rate this question:

Correct Answer
A. 2Explanation
The square root of 2 to the square root of 2 power can be simplified as 2^(√2). Then, raising 2 to the power of √2 is equivalent to taking the square root of 2. Therefore, the square root of 2 to the square root of 2 power is equal to 2.Rate this question:

What is the square root of 2 to the negative 9 plus 3 power?
-
1/4
-
1/8
-
2/8
-
1/2
Correct Answer
A. 1/8Explanation
To simplify the expression, we need to evaluate the square root of 2 to the negative 9 plus 3 power. First, we simplify the exponent by adding -9 and 3, which gives us -6. Then, we take the square root of 2 to the power of -6. The square root of 2 is approximately 1.414, and raising it to the power of -6 gives us a very small number. Therefore, the answer is 1/8, as it is the only option that represents a small fraction.Rate this question:

Draw 2 supplementary angles. One angle is x-15 degrees and one is 2x degrees. What is the value of x in degrees?
-
65 degrees
-
130 degrees
-
100 degrees
-
75 degrees
Correct Answer
A. 65 degreesExplanation
Two angles are called supplementary if the sum of their measures is equal to 180 degrees. In this question, we are given two angles: one is x-15 degrees and the other is 2x degrees. To find the value of x, we need to set up an equation. The sum of the measures of the two angles is (x-15) + (2x) = 180. Simplifying this equation, we get 3x - 15 = 180. Adding 15 to both sides, we have 3x = 195. Dividing both sides by 3, we find x = 65 degrees. Therefore, the value of x is 65 degrees.Rate this question:
