Answer:
no simplify. answer is:
b. log(1/7)
ANSWER
d.
[tex] \frac{1}{7} [/tex]
EXPLANATION
We want to simplify
[tex] {10}^{ log( \frac{1}{7} ) } [/tex]
Recall that the common logarithm has a base of 10.
This implies that,
[tex] {10}^{ log( \frac{1}{7} ) } = {10}^{ log_{10}( \frac{1}{7} ) } [/tex]
Recall again that:
[tex] {p}^{ log_{p}(q) } = q[/tex]
Therefore,
[tex] {10}^{ log( \frac{1}{7} ) } = {10}^{ log_{10}( \frac{1}{7} ) } = \frac{1}{7} [/tex]
if the probability of p(m and n) =0.2 p(m)=0.4 and m and independent events, what is p(n)?
Answer:
P(n) = 0.5
Step-by-step explanation:
For two events which are independent, we use the multiplication rule which states P (A and B) = P(A) * P(B). Substitute P(m) = 0.4 and P(m and n) = 0.2 into this formula.
P (m and n) = P(m) * P(n)
0.2 = 0.4*P(n)
Divide by 0.4 on both sides.
0.2 / 0.4 = P(n)
0.5 = P(n)
Compute all values of x such that x-1 is the reciprocal of x+1. Express your answer in simplified radical form.
Answer:
x = ±√2
Step-by-step explanation:
x - 1 = 1/(x + 1)
(x -1)(x + 1) = 1 Multiplied each side by x + 1
x² - 1 = 1 Difference of two squares
x² = 2 Add 1 to each side
x = ±√2
x-1 is the reciprocal of x+1 when x = -√2 or x = √2.
Check:
(a) x = -√2
-√2 - 1 = 1/(-√2 + 1)
-(√2 + 1) = (√2 +1)/[(-√2 +1)(√2 + 1)]
-(√2 + 1) = (√2 +1)/(-2 +1)
-(√2 + 1) = (√2 +1)/(-1)
-(√2 + 1) = -(√2 +1)
(b) x = √2
√2 - 1 = 1/(√2 + 1
√2 - 1 = (√2 - 1)/[(√2 + 1)(√2 - 1) ]
√2 - 1 = (√2 - 1)/(2 - 1)
√2 - 1 = (√2 - 1)/1
√2 - 1 = √2 - 1
OK.
Answer:x = ±√2
Step-by-step explanation: this is because reciprocal means the numerator and denominator switches
So the equation is x-1=1/(x+1)

Answer:
28π and 196π
10π and 25π
2500π
A = C/4π
Step-by-step explanation:
The circumference of a circle is the distance around the edge of the circle. To find the circumference, we use the formula C = 2πr. The area of the circle is the amount inside the circle and is found using A = πr². Substitute the relevant values in each situation into the formulas to find the circumference and area.
if the radius of a circle is 14 units, what is its circumference? what is its area?
Substitute r = 14.
C = 2πr = 2π(14) = 28π
A = πr² = π(14)² = 196π
if a circle has diameter 10 units, what is its circumference? what is its area?
Substitute r = 5.
C = 2πr = 2π(5) = 10π
A = πr² = π(5)² = 25π
if a circle has circumference 100π units, what is its area?
Substitute C = 100π to find the radius. Then substitute the radius into the are formula.
C = 2πr
100π=2πr
100 = 2r
50 = r
A = πr² = π(50)² = 2500π
if a circle has circumference c, what is its area in terms of c?
Cole the circumference formula for r. Then substitute the expression into the area formula.
C = 2πr
r = C / 2π
A = πr² = π(C/2π)² = πC/4π² = C/4π

2. Circumference: [tex]\(10\pi\)[/tex]units, Area: [tex]\(25\pi\)[/tex]square units.
3. Area: [tex]\(2500\pi\)[/tex]square units.
4. Area: [tex]\(\frac{C^2}{4\pi}\)[/tex] square units.
Let's go through each question one by one, using the formulas for the circumference and area of a circle.
1. If the radius of a circle is 14 units, what is its circumference? What is its area?
- The circumference [tex]\( C \)[/tex] of a circle is given by the formula:
[tex]\[ C = 2\pi r \][/tex]
where [tex]\( r \)[/tex] is the radius.
Given [tex]\( r = 14 \)[/tex] units, we have:
[tex]\[ C = 2\pi \times 14 = 28\pi \text{ units} \][/tex]
- The area [tex]\( A \)[/tex]of a circle is given by the formula:
[tex]\[ A = \pi r^2 \][/tex]
Given [tex]\( r = 14 \)[/tex] units, we have:
[tex]\[ A = \pi \times 14^2 = \pi \times 196 = 196\pi \text{ square units} \][/tex]
2. If a circle has diameter 10 units, what is its circumference? What is its area?
- The diameter [tex]\( d \)[/tex] is related to the radius by [tex]\( d = 2r \)[/tex]. Therefore, the radius [tex]\( r \)[/tex] is:
[tex]\[ r = \frac{d}{2} = \frac{10}{2} = 5 \text{ units} \][/tex]
- Using the circumference formula [tex]\( C = 2\pi r \):[/tex]
[tex]\[ C = 2\pi \times 5 = 10\pi \text{ units} \][/tex]
- Using the area formula [tex]\( A = \pi r^2 \):[/tex]
[tex]\[ A = \pi \times 5^2 = \pi \times 25 = 25\pi \text{ square units} \][/tex]
3. If a circle has circumference [tex]\( 100\pi \)[/tex] units, what is its area?
- Given the circumference [tex]\( C = 100\pi \),[/tex] we can find the radius [tex]\( r \)[/tex] using the formula [tex]\( C = 2\pi r \):[/tex]
[tex]\[ 100\pi = 2\pi r \][/tex]
Dividing both sides by [tex]\( 2\pi \):[/tex]
[tex]\[ r = \frac{100\pi}{2\pi} = 50 \text{ units} \][/tex]
- Using the area formula [tex]\( A = \pi r^2 \):[/tex]
[tex]\[ A = \pi \times 50^2 = \pi \times 2500 = 2500\pi \text{ square units} \][/tex]
4. If a circle has circumference [tex]\( C \),[/tex] what is its area in terms of [tex]\( C \)[/tex]
- Given the circumference [tex]\( C \),[/tex] we can express the radius [tex]\( r \)[/tex] in terms of [tex]\( C \)[/tex] using the formula [tex]\( C = 2\pi r \):[/tex]
[tex]\[ r = \frac{C}{2\pi} \][/tex]
- Using the area formula [tex]\( A = \pi r^2 \)[/tex] and substituting [tex]\( r = \frac{C}{2\pi} \):[/tex]
[tex]\[ A = \pi \left( \frac{C}{2\pi} \right)^2 = \pi \left( \frac{C^2}{4\pi^2} \right) = \frac{\pi C^2}{4\pi^2} = \frac{C^2}{4\pi} \][/tex]
Assume that x is a variable that has been declared as a double and been given a value. Write an expression to compute the quartic root of x. The quartic root of a number is the square root of its square root. EXAMPLES: For example, the quartic root of 16.0 is 2.0 because: the square root of 16.0 is 4.0 and the square root of 4.0 is 2.0. Another example: the quartic root of 81.0 is 3.0 because the square root of 81.0 is 9.0 and the square root of 9.0 is 3.0. Thus, to find the quartic root of a number you take the square root of the number and then take the square root of that. In this exercise you must find the quartic root of x in a single expression-- you must not write any statements. Also, you may only use the sqrt() static method defined in the Math class-- no other methods. (HINT: you will need to call the Math.sqrt() method twice-- and you will need to pass the return value of one of those calls as argument to the other call. AND REMEMBER: write an expression, not a statement.)
Answer:
sqrt(sqrt(x))
Step-by-step explanation:
A quartic root of is written mathematically as . THe quartic root of 16 is 2 since 2*2*2*2 = 16. However, a quartic root can also be defined as the square root of a square root. For example the √16 = 4 and the √4 = 2. This is the same response as taking the quartic root. This means you can write it as the sqrt(sqrt(x)). In the example, it would be sqrt(sqrt(16)) = sqrt(4) = 2.
The quartic root of a variable x can be calculated using the expression Math.sqrt(Math.sqrt(x)), which calls the square root function twice. This computes the square root of x, then computes the square root of the result, yielding the quartic root.
Explanation:In order to compute the quartic root of a variable x, we call the Math.sqrt() method twice in a nested manner. The quartic root is essentially the square root of a square root, hence the need for the double call. The appropriate expression in this case would be:
Math.sqrt(Math.sqrt(x))
This expression first computes the square root of x and then computes the square root of the result, which gives us the quartic root of x. As a result, if x is 16.0, the result of this expression would be 2.0, and if x is 81.0, the result would be 3.0.

Destructimous has 7 sonic blasts and 13 heat rays. It also has a 2/7 chance of using its ultra power blast. Luckily, Octagon’s sheild reflected that blast and stopped all the robots. How many ultra power bots did Destructimous have? Pls show/ explain your work. (i know the answer i just dont know how to find it).
Destructimous had 6 ultra power blasts.
The total number of blasts Destructimous has is:
Total blasts = Sonic blasts + Heat rays
Total blasts = 7 + 13
Total blasts = 20
Now, we know that Destructimous has a 2/7 chance of using its ultra power blast. To find out how many ultra power blasts it fires, we calculate 2/7 of the total blasts:
Ultra power blasts = (2/7) * Total blasts
Ultra power blasts = (2/7) * 20
Ultra power blasts = 40/7
Now, since we can't have a fraction of a blast, we need to round this number to the nearest whole number. In this case, 40/7 is approximately 5.71, so when rounded, it's 6.
So, Destructimous had 6 ultra power blasts.

Experimenting, you have found that 12 ounces of 180°F coffee in your favorite cup will take 20 minutes to cool to a drinking temperature of 110°F in a 70°F room. Assume that when you add cream to the coffee, the two liquids are mixed instantly, and the temperature of the mixture instantly becomes the weighted average of the temperature of the coffee and of the cream (weighted by the number of ounces of each fluid). Also assume that the cooling constant of the liquid (the constant k in the equations on p. 237 in section 3.8 for Newton's Law of Cooling) does not change when you add the cream. (a) If you add 2 ounces of 40°F cream to the 180°F coffee in the cup, how long will it take for the mixture to reach drinking temperature? Give your answer (in minutes) in decimal form with at least 3 decimal digits (for example, 12.345 minutes).
Answer:
16.033 min
Step-by-step explanation:
We can write Newton's Law of Cooling as
T = Tₐ + (T₀ - Tₐ)e^(-kt), where
Tₐ = ambient temperature of the surroundings
T₀ = initial temperature of the object
k = the cooling constant
t = the time
(1) Calculate the cooling constant
Data:
T = 110 °F
T₀ = 180 °F
Tₐ = 70 °F
t = 20 min
Calculation:
110 = 70 + (180 - 70)e^(-k×20)
40 = 110e^(-20k)
0.363 64 = e^(-20k)
-1.0116 = -20k
k = 0.050 580 min⁻¹
(2)After adding cream
(a) Calculate T₀
2 oz × 40 °F + 12 oz × 180 °F = 14 oz × T₀
80 °F + 2160°F = 14T₀
2240 °F = 14T₀
T₀ = 160 °F
(b) Calculate the time to cool to drinking temperature
110 = 70 + (160 - 70)e^(-0.050 580t)
40 = 90e^(-0.050 580t)
0.444 44 = e^(-0.050 580t)
-0.810 93 = -0.050580t
t = 16.033 min
It will take 16.033 min for the mixture to reach drinking temperature
To determine the time it takes for the mixture to reach drinking temperature, we first calculate the initial temperature of the mixture after adding 2 ounces of 40°F cream to the 180°F coffee, which turns out to be 165°F. Then, according to Newton's Law of Cooling, the time it takes for the mixture to decrease from 165°F to the drinking temperature of 110°F would be the same as the time it took for the original coffee to cool from 235°F to 180°F, given the cooling constant doesn't change when we add the cream. Therefore, the mixture will take approximately 20 minutes to reach drinking temperature.
Explanation:To determine the time it takes for the mixture to reach drinking temperature, we first need to calculate the initial temperature of the mixture. When you add 2 ounces of 40°F cream to the 180°F coffee, the temperature of the mixture instantly becomes the weighted average of the temperature of the coffee and of the cream. Thus, we have:
(12 * 180 + 2 * 40) / (12 + 2) = 165°F.
Now we need to calculate the time it takes for the mixture to decrease from 165°F to the drinking temperature of 110°F. According to Newton's Law of Cooling, the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature. If we assume that the proportionality constant (or the cooling constant) doesn't change when we add the cream, then the time it takes for the mixture to cool from 165°F to 110°F will be the same as the time it took for the original coffee to cool from 235°F (165 + 70) to 180°F (110 + 70), which is 20 minutes. We can conclude that the mixture will take approximately 20 minutes to reach drinking temperature.

Answer:
Step-by-step explanation:
0.3. x + 18.3
The data for tree 1 is an illustration of a linear equation.
The linear equation that fits the data for tree 1 is: [tex]\mathbf{y = 0.3x + 18.3}[/tex]
From the complete question, we have the following points
[tex]\mathbf{(x_1,y_1) = (1,18.6)}[/tex]
[tex]\mathbf{(x_2,y_2) = (3,19.2)}[/tex]
First, we calculate the slope (m)
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{19.2 - 18.6}{3 -1}}[/tex]
[tex]\mathbf{m = \frac{0.6}{2}}[/tex]
[tex]\mathbf{m = 0.3}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
So, we have:
[tex]\mathbf{y = 0.3(x - 1) + 18.6}[/tex]
[tex]\mathbf{y = 0.3x - 0.3+ 18.6}[/tex]
[tex]\mathbf{y = 0.3x + 18.3}[/tex]
Hence, the linear equation that fits the data for tree 1 is: [tex]\mathbf{y = 0.3x + 18.3}[/tex]

[tex](D^2-12D-45)[e^{-3x}]=9e^{-3x}-12(-3e^{-3x})-45e^{-3x}=0[/tex]
The linearly independent functions that are annihilated by the differential operator d2 − 12d - 45 are e^{15x} and e^{-3x}, found by solving the quadratic equation associated with the differential equation.
Explanation:The differential operator given is d2 − 12d - 45. To find out the linearly independent functions that are annihilated by this operator, we have to solve the homogeneous differential equation d2 − 12d - 45 = 0. This is a second order equation, so we expect two linearly independent solutions.
To find the solutions, we seek the roots of the associated quadratic equation m^2 - 12m -45 = 0. This can be factored into (m-15)(m+3), thus giving roots m = 15 and m = -3.
The general forms of the solutions for these roots are e^{15x} and e^{-3x} respectively. Therefore, the functions e^{15x} and e^{-3x} are linearly independent functions that are annihilated by the given differential operator d2 − 12d - 45.

Complete the table to represent how much each individual monthly deposit of $50 will be worth at the end of 12 months. Enter your answers as an expression in the form
a(1 + r)n, as shown for the first month.
The first month has the equation raised to 11 which is the number of months left in the period.
So each month the equation would be the same except it would be raised to 1 less than the previous month.
Month 2 = 50(1.003)^10
Month 3 = 50(1.003)^9
Month 4 = 50(1.003)^8
Month 5 = 50(1.003)^7
Month 6 = 50(1.003)^6
Month 7 = 50(1.003)^5
Month 8 = 50(1.003)^4
Month 9 = 50(1.003)^3
Month 10 = 50(1.003)^2
Month 11 = 50(1.003)^1
Month 12 = 50(1.003) ( the last month would not be raised to anything)

Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18–31) still live at home with their parents. A group of students wants to conduct a study to determine whether this result is true for students at their campus. They survey 300 randomly selected students at their campus and determine that 43% of them live at home with their parents. With this data, they test the following hypotheses. H0: Of Millennial students at their campus, 36% live at home with their parents. Ha: More than 36% of Millennial students at their campus live at home with their parents. In order to assess the evidence, which question best describes what we need to determine? If we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 36%? If we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 43% or more? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 36%? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 43%?
To assess the evidence of Hypothesis testing, the students need to determine the likelihood of the proportion of Millennial students at their campus that live at home with their parents being 36% or higher.
Explanation:The question here is regarding the testing of a population proportion using statistical hypothesis testing, specifically a one-sample z-test. The null hypothesis (H0) is that the population proportion is equal to a specified value, in this case, 36%). The alternative hypothesis (Ha) is that the population proportion is greater than the specified value (more than 36%).
The question we need to answer is 'If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?'
The scenario suggests an indication towards a right-tailed z-test as we're looking to see if the data indicates a proportion >36%. However, as with all statistical tests, one should be cautious about drawing definitive conclusions without additional context and understanding the potential for sampling variability and error.
