A certain element decays at a constant rate of 6% per year. If you start with 20 grams of the element, how long will it take before there are only four grams left?
Answer:
26.0 years
Step-by-step explanation:
It will take approximately 16.79 years (to the nearest hundredth) for the initial mass of 20 grams to decay to four grams, given a constant decay rate of 6% per year.
To determine how long it will take for the 20 grams of the element to decay to four grams, we need to calculate the time using the given decay rate.
Given:
Initial mass (M₀) = 20 grams
Decay rate: 6% per year
Let's set up an equation to represent the decay of the element:
M(t) = M₀ * (1 - r)^t
Here, M(t) represents the mass at time t in years, M₀ is the initial mass, r is the decay rate (expressed as a decimal), and t is the time in years.
We want to find the value of t when M(t) = 4 grams:
\(4 = 20 * (1 - 0.06)^t\)
Dividing both sides by 20:
\(0.2 = (1 - 0.06)^t\)
Taking the natural logarithm of both sides:
\(ln(0.2) = ln[(1 - 0.06)^t]\)
Using logarithmic properties, we can simplify further:
\(ln(0.2) = t * ln(1 - 0.06)\)
Now, we can solve for t by dividing both sides of the equation by ln(1 - 0.06):
t =\(ln(0.2) / ln(1 - 0.06)\)
Using a calculator, we find:
t ≈ 16.79 years
Therefore, it will take approximately 16.79 years (to the nearest hundredth) for the initial mass of 20 grams to decay to four grams, given a constant decay rate of 6% per year.

A 1.2kg pack of carrots for $1
or a
700g bag for $0.77
Answer: 1.2kg pack of carrots for $1
Step-by-step explanation:
To compare the two deals, we need to calculate the price per kilogram for each option.
For the first option, the price per kilogram is:
1 pack of 1.2kg carrots for $1
Price per kilogram = $1 ÷ 1.2kg = $0.83/kg
For the second option, the price per kilogram is:
1 bag of 700g carrots for $0.77
Price per kilogram = $0.77 ÷ (700g ÷ 1000g/kg) = $1.10/kg
Therefore, the better deal is the 1.2kg pack of carrots for $1, as it has a lower price per kilogram ($0.83/kg) compared to the 700g bag for $0.77 ($1.10/kg).
Answer:
1.2kg pack of carrots for $1

A neighborhood is trying to set up school carpools, but they need to determine the number of students who need to travel to the elementary school (ages 5-10), the middle school (ages 11-13), and the high school (ages 14-18). A histogram summarizes their findings:
Histogram titled Carpool, with Number of Children on the y axis and Age Groups on the x axis. Bar 1 is 5 to 10 years old and has a value of 3. Bar 2 is 11 to 13 years old and has a value of 7. Bar 3 is 14 to 18 years old and has a value of 4.
Which of the following data sets is represented in the histogram?
{3, 3, 3, 7, 7, 7, 7, 7, 7, 7, 4, 4, 4, 4}
{5, 10, 4, 11, 12, 13, 12, 13, 12, 11, 14, 14, 19, 18}

{3, 5, 10, 11, 13, 7, 18, 14, 4}
The correct answer is that the data set {3, 7, 4} is represented in the given histogram.(option-a)
The given histogram represents the number of children in each age group who need to travel to school. Since the histogram has only three bars, we can conclude that there are only three age groups.
The first bar represents children aged 5-10, of which there are 3. The second bar represents children aged 11-13, of which there are 7. The third bar represents children aged 14-18, of which there are 4.
Therefore, the data set that is represented in the histogram is:
{3, 7, 4}
None of the other data sets given match the values in the histogram. The first data set has duplicate values and is not sorted by age group. The second data set includes ages that are not represented in the histogram. The third data set has values for ages 6, 11, 12, 13, 14, 15, 17, and 18, but the histogram does not have bars for all those ages. (option-a)

I am confused on how to solve this. NOTE: the lower limit for the second function is (-6) NOT 6. Wouldn't let me type it in correctly.\(\int\limits^6_3 {|x-4|} \, dx + \int\limits^0_6 {\sqrt{36-x^2} } \, dx\)
I think how you approach this depends on your knowledge of calculus.
If you don't know how to compute definite integrals yet, but you do know that they represent signed areas under curves, then you can plot both curves |x - 4| and √(36 - x ²), then recognize that the areas represented by these integrals are areas of geometric shapes. (See attached images)
First integral: if you plot |x - 4| on the interval [3, 6], you'll see that the integral corresponds to the area of two triangles. One of them has base = height = 1, and the other has base = height = 2. Then
\(\displaystyle\int_3^6|x-4|\,\mathrm dx=\frac12\times1\times1+\frac12\times2\times2=\frac52\)
Second integral: if \(y=\sqrt{36-x^2}\), then \(x^2+y^2=6^2\), meaning this curve is the upper half of a circle with radius 6. On the interval [-6, 0], the area amounts to 1/4 of the total area of such a circle, so that
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=\frac{\pi\times6^2}4=9\pi\)
* * *
If you already know a few things about calculus and integration, you can compute these areas directly.
First integral:
\(\displaystyle\int_3^6|x-4|\,\mathrm dx=\int_3^4(4-x)\,\mathrm dx+\int_4^6(x-4)\,\mathrm dx\)
\(\displaystyle\int_3^6|x-4|\,\mathrm dx=\left(4x-\frac{x^2}2\right)\bigg|_{x=3}^{x=4}+\left(\frac{x^2}2-4x\right)\bigg|_{x=4}^{x=6}\)
\(\displaystyle\int_3^6|x-4|\,\mathrm dx=\left(\left(4\times4-\frac{4^2}2\right)-\left(4\times3-\frac{3^2}2\right)\right)+\left(\left(\frac{6^2}2-4\times6\right)-\left(\frac{4^2}2-4\times4\right)\right)\)
\(\displaystyle\int_3^6|x-4|\,\mathrm dx=\frac52\)
Second integral:
Substitute x = 6 sin(t ) and dx = 6 cos(t ) dt, then
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=\int_{-\frac\pi2}^0\sqrt{6^2-(6\sin(t))^2} (6\cos(t))\,\mathrm dt\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=36\int_{-\frac\pi2}^0\cos (t) \sqrt{1-\sin^2(t)} \,\mathrm dt\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=36\int_{-\frac\pi2}^0\cos (t) \sqrt{\cos^2(t)} \,\mathrm dt\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=36\int_{-\frac\pi2}^0\cos (t) |\cos(t)| \,\mathrm dt\)
For t ∈ [-π/2, 0], cos(t ) > 0, so |cos(t )| = cos(t ) :
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=36\int_{-\frac\pi2}^0\cos^2(t)\,\mathrm dt\)
Recall the half-angle identity,
cos²(t ) = (1 + cos(2t )) / 2
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=18\int_{-\frac\pi2}^0(1+\cos(2t))\,\mathrm dt\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=18\left(t+\frac{\sin(2t)}2\right)\bigg|_{t=-\frac\pi2}^{t=0}\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=18\left(\left(0+\frac{\sin(2\times0)}2\right)-\left(-\frac\pi2+\frac{\sin\left(2\times\left(-\frac\pi2\right)\right)}2\right)\right)\)
\(\displaystyle\int_{-6}^0\sqrt{36-x^2}\,\mathrm dx=9\pi\)

Index is the power or exponent which is raised to a number or a variable. For example, in number 3², 2 is the index of 3. The plural form of index is indices
Given: (8.1)(8.1²)⁴
To simplify these indices, we are going to apply one of the indices, which is expressed below: (4³)² = 4³ ˣ ² = 4⁶. We basically multiply the powers
We also need another law which is expressed below:

Answer: Experimental probability
Step-by-step explanation:
There are two kinds of probability: Theoretical probability and Experimental probability.
To calculate theoretical probability we divide favorable outcomes by total outcomes.
To calculate experimental probability we divide number of times an event occurs by the total number of trials or times the activity is performed.
Here, A child gets 20 heads out of 30 tosses of a coin. If he declared the chance of getting a head with that coin were 2/3, which is dependent on the activity he performed, thus it is an experimental probability.
