Question 8: Determine the value of expression 5^log525⋅2^log28⋅3^log33 and justify your answer by referring to the properties of logarithms. Do not use a calculator!
The value of the expression 5^log525⋅2^log28⋅3^log33 is 125.
To justify this answer, let's analyze the expression step by step using the properties of logarithms:
1. Start with the expression: 5^log525⋅2^log28⋅3^log33.
2. We know that log(base a)b = c is equivalent to a^c = b.
3. Applying this property to the expression, we have 5^log525 = 25, since log(base 5)25 = 2.
4. Similarly, 2^log28 = 8, because log(base 2)8 = 3.
5. Lastly, 3^log33 = 3, as log(base 3)3 = 1.
6. Combining these results, the expression simplifies to 25⋅8⋅3.
7. Evaluating the multiplication, we get 25⋅8⋅3 = 600.
Therefore, the value of the expression 5^log525⋅2^log28⋅3^log33 is 125

One way of writing 75 as the sum of consecutive whole numbers is 24 + 25 + 26. How many other ways are there?
Answer:
None. \(24+25+26\) is the only valid answer
Step-by-step explanation:
We can create an expression for the sum of 3 consecutive numbers.
\(S=x+(x+1)+(x+2)\)
Which we can simplify to
\(S=x+x+1+x+2\)
\(S=3x+3\)
In this example we are given a sum of 75.
\(75=3x+3\)
Lets solve for \(x\).
Subtract 3 from both sides.
\(72=3x\)
Divide both sides by 3.
\(24=x\)
To find out what the 3 numbers are we can plug in 24 for x
\(x+(x+1)+(x+2)\)
\(24+(24+1)+(24+2)\)
\(24+25+26\)
Answer:
4 other ways (5 ways, total).
Step-by-step explanation:
You want to know how many other ways 75 can be written as the sum of consecutive whole numbers other than 24+25+26.
SolutionIf 75 is written as the sum of an odd number of integers, the middle integer of the set will be 75 divided by the number of integers. The divisors of 75 are {1, 3, 5, 15, 25, 75}. If the numbers in the sum are non-negative, the number of integers involved cannot be more than √(2·75) ≈ 12. Then allowed odd numbers of integers in the sum are 3 and 5.
If 75 is written as the sum of an even number of integers, the quotient when 75 is divided by the number of integers must be 1/2 more than a whole number. Such integer divisors are 2, 6, and 10.
Sums37 + 38 = 75 . . . . 2 integers
24 + 25 + 26 = 75 . . . . 3 integers (the given sum)
13 + 14 + 15 + 16 + 17 = 75 . . . . 5 integers
10 + 11 + 12 + 13 + 14 + 15 = 75 . . . . 6 integers
3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 75 . . . . 10 integers
There are 4 other ways to use consecutive non-negative integers to make a sum of 75.
Cellular phone company A charges a $27.95 monthly fee and $.12/min for local calls. Company B charges $12.95 a month and $.32/min for local calls.
A) Write an equation to represent the number of minutes a month, x, the companies will charge the same amount.
B) After how many minutes will company A and Company B charge the same amount?
C) What is that amount?
On solving the provided question, we can say that, by solving the equations that amount is $36.95
What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
Suppose x be the number of minutes of local calls when cost of plans are the same
Cost of Plan 1is $27.95+.12x
Cost of Plan 2 is $12.95+.32x
\($27.95+0.12x=12.95+.32x \\\)
\($27.95-$12.95+.12x-.12x=$12.95-$12.95+.32x-.12x\\$15.00=.20x\)
x=75 minutes
\(27.95+.12(75)=12.95+.32(75)\\27.95+9.00=12.95+24.00\\36.95=36.95\)

A classroom of children has 16 boys and 19 girls, in which five students are chosen at random to do presentations. What is the probability that more boys than girls are chosen?
The probability that more boys than girls are chosen is approximately 0.171.
To solve this problem, we can use the binomial distribution. Let X be the number of boys chosen out of the 5 students selected.
Then, X has a binomial distribution with parameters n = 5 and p = 16/(16+19) = 16/35, since there are 16 boys and 19 girls, and we are selecting 5 students at random.
We want to find the probability that more boys than girls are chosen, which is the same as the probability that X is greater than 2. We can compute this probability using the cumulative distribution function (CDF) of the binomial distribution:
P(X > 2) = 1 - P(X ≤ 2)
= 1 - (P(X = 0) + P(X = 1) + P(X = 2))
Using the binomial probability formula, we can calculate each term of the sum:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where (n choose k) = n! / (k! * (n-k)!) is the binomial coefficient.
Thus, we have:
P(X = 0) = (5 choose 0) * (16/35)^0 * (19/35)^5 = 0.107
P(X = 1) = (5 choose 1) * (16/35)^1 * (19/35)^4 = 0.349
P(X = 2) = (5 choose 2) * (16/35)^2 * (19/35)^3 = 0.373
Substituting these values into the formula for P(X > 2), we get:
P(X > 2) = 1 - (0.107 + 0.349 + 0.373) = 0.171
Therefore, the probability that more boys than girls are chosen is approximately 0.171.

A spring with a spring constant k of 100 pounds per foot is loaded with 1-pound weight and brought to equilibrium. It is then stretched an additional 1 inch and released. Find the equation of motion, the amplitude, and the period. Neglect friction. Then y(t) = cos(sqrt(100/(1/32)*t) where t is time in (seconds) and y(t) is displacement (in feet). Hint: Be careful about units here. In particular, remember that the pound is a unit of force. You will need to use the fact that gravitational acceleration is 32 ft/s? in order to convert to units of mass. Amplitude: __ inch(es) Period: ___ second(s).
First, we need to convert the given weight to mass. Since we know that gravitational acceleration is 32 ft/s² and the weight is 1 pound, we can calculate the mass.
Weight = Mass × Gravitational acceleration
1 lb = Mass × 32 ft/s²
Mass = 1 lb / 32 ft/s² = 1/32 slugs
Now, we need to find the angular frequency (ω) using the formula ω = sqrt(k/m):
ω = sqrt(100 lb/ft / (1/32 slugs)) = sqrt(3200) = 40 rad/s
The equation of motion will be:
y(t) = A * cos(ωt)
Since the spring is stretched an additional 1 inch (1/12 ft), that will be the amplitude (A): Amplitude = 1/12 ft
Now we can write the complete equation of motion:
y(t) = (1/12) * cos(40t)
In conclusion: Amplitude: 1 inch (1/12 ft)
Period: π/20 seconds

come up with two data sets a and b with same number of data points, where data set a has the larger standard deviation but the smaller range.
Data set A and B have the same number of data points, but A has a larger standard deviation and a smaller range compared to B.

In this example, both data sets have five data points, but Data Set A has a larger standard deviation while having a smaller range compared to Data Set B.
Data Set A has a larger standard deviation because the values are more spread out from the mean.
The standard deviation of Data Set A is approximately 3.16, while the range is,

How much money was borrowed at 10%?
How much money was borrowed at 12%?
How much money was borrowed at 14%?
Answer:
10% — $550012% — $700014% — $8500Step-by-step explanation:
You want to know the amount borrowed at 10%, 12%, and 14% if the total borrowed was $21000, the total interest was $2580, and the total of amounts borrowed at 10% and 14% was double the amount borrowed at 12%.
EquationsThe relations give rise to three equations. If we let x, y, z represent the respective amounts borrowed at 10%, 12%, and 14%, we have ...
x + y + z = 21000 . . . . . . total borrowed
0.10x +0.12y +0.14z = 2580 . . . . . . total interest
x + y = 2z . . . . . . . . . . . relationship between amounts
Writing the last equation as ...
x -2y +z = 0
we can formulate the problem as a matrix equation and use a solver to find the solution. We have done that in the attachment. It tells us the amounts borrowed are ...
10% — $550012% — $700014% — $8500__
Additional comment
Recognizing that the amount at 12% is 1/3 of the total, we can use that fact to rewrite the other two equations. The interest on the $7000 at 12% is $840, so we have ...
x + y = 140000.10x +0.14y = 1740These two equations have the solution shown above. (It is usually convenient to solve them by substituting for x in the second equation.)

In Complex numbers: not defined for \(x = 2i, -2i\)
Step-by-step explanation:
Fraction becomes undefined when the denominator = 0
\(x^2 + 4 = 0\)
Has no real solutions
The fraction is defined for all real values of x
\(x^2 + 4 = 0\)
\(x^2 = -4\)
\(x = 2i, -2i\)
The fraction is not defined for \(x = \dfrac{+}{-2i}\) (in Complex Numbers)
