sketch the graphs of the functions y = x and y = x^2 within the domain -2 < x < 2. Then find the area bounded by the two functions.​

Answers

Answer 1

The area bounded by the functions y = x and y =[tex]x^2[/tex] within the domain -2 < x < 2 is 1/6 square units.

To sketch the graphs of the functions y = x and y = x^2 within the domain -2 < x < 2, we can plot a few points and connect them to form the curves.

For y = x.

When x = -2, y = -2.

When x = -1, y = -1.

When x = 0, y = 0.

When x = 1, y = 1.

When x = 2, y = 2.

Connecting these points, we get a straight line passing through the origin and extending to -2 and 2 on the x-axis.

For y = [tex]x^2[/tex]:

When x = -2, y = 4.

When x = -1, y = 1.

When x = 0, y = 0.

When x = 1, y = 1.

When x = 2, y = 4.

Connecting these points, we get a symmetrical U-shaped curve opening upward.

Now, to find the area bounded by the two functions, we need to determine the points of intersection between the two curves.

Setting y = x and y =[tex]x^2[/tex] equal to each other, we have:

x = [tex]x^2[/tex].

Simplifying this equation, we get:

x^2 - x = 0.

Factoring out an x, we have:

x(x - 1) = 0.

So, x = 0 or x = 1.The points of intersection are (0, 0) and (1, 1).

To find the area between the curves, we need to integrate the difference between the two functions over the interval [0, 1]. Since the curve y = x is above y = x^2 in this interval, the integral becomes:

∫[0, 1] (x - [tex]x^2[/tex]) dx.

Evaluating this integral gives us the area bounded by the curves.

∫[0, 1] (x -[tex]x^2[/tex]) dx = [[tex]x^2[/tex]/2 - x^3/3] evaluated from 0 to 1.

Plugging in the upper and lower limits, we get:

[1/2 - 1/3] - [0] = 1/6.

Answers

Answer:

  a) x ≈ -0.5958

  b) x ≈ 1.1403

  c) no solutions

Step-by-step explanation:

You want to solve various exponential equations:

9^(3x-2) = 5^(7x -1)2(3^(2x)) -5(3^x) = 73^x +1 +56(3^-x) = 0

Strategy

The first of these can be solve using logarithms to transform it to a linear equation. The other two can be solve by the substitution z=3^x. They each then become ordinary quadratic equations in z.

a) 9^(3x-2) = 5^(7x -1)

Taking logs, we have ...

  (3x -2)log(9) = (7x -1)log(5)

  x(3log(9) -7log(5)) = -log(5) +2log(9)

  x = log(81/5)/log(729/78125) ≈ -1.2095/-2.0301

  x ≈ -0.5958

b) 2(3^(2x)) -5(3^x) = 7

Using the substitution described above, this is ...

  2z² -5z = 7

  z² -(5/2)z = 7/2 . . . . . divide by 2

  z² -(5/2)z +25/16 = (7/2) +(25/16) . . . . . . complete the square

  (z -5/4)² = 81/16

  z = 5/4 +9/4 . . . . . . z cannot be negative

  x = log(3.5)/log(3)

  x ≈ 1.1403

c) 3^x +1 +56(3^-x) = 0

  z +1 +56/z = 0 . . . . . using z = 3^x

  z² +z +56 = 0 . . . . . multiply by z

Descartes' rule of signs tells you this has no positive real solutions for z, so the original equation has no solutions. (The graph in the third attachment has no x-intercepts.)

__

Additional comment

In general, equations consisting of a combination of polynomial and exponential expressions (as in (b) and (c)) cannot be solved algebraically. If the exponential expressions are related in a way that allows substitution (as here), then there may be algebraic methods that will work.

We like to write the equations in the form f(x) = 0, so a graphing calculator's display of the function zeros is a display of solutions to the equation. This is what we have done in the first three attachments.

Using the log expressions we developed, you can find the values of x to as many decimal places as your calculator provides. More significant digits are shown in the fourth attachment.

Answer: 0.6156 or in fraction form, 62%

Step-by-step explanation: To find the probability that at least one of the two people does not go on vacation, we subtract the probability that both of them go on vacation from 1. The probability that both go on vacation is 0.62 * 0.62 = 0.3844.

Therefore, the probability that one or both of them does not go on vacation is 0.6156, or about 62%.

Answer: 0.2356 and 0.1444

Step-by-step explanation:

62% of Americans go on Vacation

So out of 100 Americans, 62 go on vacation

The chance of one of them NOT going on vacation is 100-62 or 38%, however, the other person has to go on vacation, so it's 38%*62% or 0.2356, approx 40%*60% or 0.24

The chance of both of them do not go on vacation is 38%*38%, or 0.1444 or approx 40%*40% or 0.16 (very rough calculating)

a. 2/169
b. 3/676
c. 1/169
d. 1/221

Answers

The probability of drawing a King and then another King is 1/221. Hence, the correct option is d. 1/221.

How to find  the probability of drawing a King and then another King

Number of favorable outcomes: There are 4 Kings in a deck of 52 playing cards. After drawing the first King, there will be 3 Kings remaining in the deck.

Number of possible outcomes: After drawing the first card, there will be 51 cards left in the deck. For the second card, any one of the remaining 51 cards can be drawn.

Thus, the probability can be calculated as follows:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

           = (4/52) * (3/51)

           = 12/2652

           = 1/221

Therefore, the probability of drawing a King and then another King is 1/221. Hence, the correct option is d. 1/221.

A certain radioactive substance decays by 2.9% each year. Find the half-life of the substance, to 2 decimal places.
How many in years?

Answers

Answer:

23.90 years

Step-by-step explanation:

To find the half-life of a radioactive substance, we can use the formula:

[tex]\boxed{\begin{minipage}{10 cm}\underline{Half-life formula}\\\\$ t_{1/2} =\dfrac{\ln 2}{k}$\\\\where:\\\\ \phantom{ww}$\bullet$ $t_{1/2}$ is the half-life. \\ \phantom{ww}$\bullet$ $k$ is the decay constant (percentage decay rate per year)\\ \end{minipage}}[/tex]

In this case, the decay constant is 2.9% or 0.029 (expressed as a decimal). Therefore, substitute k = 0.029 into the formula:

[tex]t_{1/2} =\dfrac{\ln 2}{0.029}[/tex]

[tex]t_{1/2} =23.9016269...[/tex]

[tex]t_{1/2} =23.90\; \sf years\; (2\;d.p.)[/tex]

Answers

From the students diagnostic exam, the 43rd Percentile, 3rd Quartile and 8 Decile are 84.5, 138.5 and 140 respectively.

Understanding Percentile, Quartile and Decile

We first need to sort the scores in ascending order:

34, 36, 66, 74, 76, 78, 84, 85, 99, 103, 121, 123, 123, 125, 130, 133, 137, 140, 145, 156

P43 represents the 43rd percentile, which is the score below which 43% of the scores fall. To find P43, we need to calculate the index of the score that corresponds to the 43rd percentile:

P43 = (43/100) * (n + 1)

P43 = (43/100) * (20 + 1)

P43 = 8.44

Since P43 is not an integer, we can take the average of the scores at the indices 8 and 9 (since the index starts from 1):

P43 = (84 + 85) / 2

P43 = 84.5

Therefore, P43 is 84.5.

The third quartile, Q3, represents the score below which 75% of the scores fall. To find Q3, we calculate the index of the score that corresponds to the 75th percentile:

Q3 = (75/100) * (n + 1)

Q3 = (75/100) * (20 + 1)

Q3 = 15.75

Since Q3 is not an integer, we can take the average of the scores at the indices 15 and 16:

Q3 = (137 + 140) / 2

Q3 = 138.5

Therefore, Q3 is 138.5.

D8 represents the score below which 80% of the scores fall. To find D8, we calculate the index of the score that corresponds to the 80th percentile:

D8 = (80/100) * (n + 1)

D8 = (80/100) * (20 + 1)

D8 = 16.8

Since D8 is not an integer, we can round up to the nearest whole number and consider the score at the 17th index:

D8 = 140

Therefore, D8 is 140.

a. Plastics vary in density when they are manufactured; therefore, their volumes are variable for a given mass. A tablet of polystyrene (a manufactured plastic) sinks in water and alcohol solution and floats in calcium chloride solution. The tablet has a mass of 0.4 grams. What is the most its volume can be?

b. What is the least its volume can be?

Answers

The most its volume can be is approximately 0.286 cm³

The least the volume of the tablet can be is approximately 0.4 cm³.

How to solve for the volume

The density of calcium chloride solution depends on its concentration. Let's assume a saturated solution, which has a density of about 1.4 g/cm³ (this value could be slightly different depending on temperature and exact concentration).

Given:

mass (m) = 0.4 grams

density (ρ) = 1.4 grams/cm³

We can rearrange the density formula to solve for volume:

ρ = m/V --> V = m/ρ

So, substituting in our values:

V = 0.4 g / 1.4 g/cm³

= 0.286 cm³

The tablet must have a volume less than or equal to 0.286 cm³ to float in the calcium chloride solution. Therefore, the most its volume can be is approximately 0.286 cm³.

b. Since the tablet sinks in water and alcohol, its density is greater than these liquids. Assuming the alcohol is ethanol, the density of ethanol is about 0.789 g/cm³, and the density of water is 1 g/cm³. As the tablet sinks in both, its density must be higher than 1 g/cm³.

Using the same volume formula and considering the density of water:

V = m/ρ

= 0.4 g / 1 g/cm³

= 0.4 cm³

Therefore, the least the volume of the tablet can be is approximately 0.4 cm³.

The period and the amplitude of the given function is 4π and 2.

To find the amplitude and period of a function using its graph, you can follow these steps:

Identify the highest point and the lowest point on the graph. These points represent the maximum and minimum values of the function.

The amplitude is equal to half the difference between the maximum and minimum values of the function. In other words, it is the distance from the midline (average value) of the function to either the highest or lowest point on the graph.

Locate two consecutive peaks or troughs on the graph. A peak is a point where the graph reaches its highest point, and a trough is a point where the graph reaches its lowest point.

Measure the horizontal distance between these two consecutive peaks or troughs. This distance is called the period of the function.

If the distance between the two peaks or troughs is not explicitly marked on the graph, you can estimate it by counting the grid lines or using the scale of the x-axis.

Hence the period and the amplitude of the given function is 4π and 2.

A complex number is a number of the form a + bi, where a and b are real numbers, and i is an imaginary number.

Where i² = -1 or i =√(-1)

A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.

Thus, we can find the equivalent to √-25 as follow:

√-25 = √(-1 * 25)

         = √(-1)* √(25)

        = i * 5

        = 5i

12. Mary wants to calculate the area of APOR. Q O draw PW so that PW || RQ and PW = V=RQ Odraw PS so that PS IRQ and point S is on RQ draw QV so that point Vis on PR and PV = VR 35° 5 cm What would be the first step in deriving the formula to calculate the area of APOR? Odraw RT so that RT bisects LPRQ and point Tis on PQ 6 cm P R​

Answers

The area of APT by the given data is 0.65 m^2.

We are given that;

PV = VR 35° 5 cm

Now,

The formula to calculate the area of APOR is to draw RT so that RT bisects ∠PRQ and point T is on PQ. This will create two congruent triangles, PRT and QRT, by the ASA criterion. Then, the area of APOR can be found by subtracting the area of QRT from the area of APT.

The length of the bottom base of APT is 2(1.5) = 3 m and the length of the top base of APT is 2(1.5 - 0.4) = 2.2 m.

You are also given that each step is 0.25 m higher than the previous one. This means that the height of APT is 0.25 m.

Using these values, you can plug them into the formula for the area of a trapezoid:

A = 0.5(a + b)h A = 0.5(3 + 2.2)(0.25) A = 0.5(5.2)(0.25) A = 0.65 m^2

Therefore, by the area answer will be 0.65 m^2.

Mr. and Mrs. Davis hope to send their son to college in 12 years. How much mo eh should they invest now at an interest rate of 9.5%per year, compounded continuously, in order to be able to contribute $9500 to his education

Answers

The formula for continuous compounding is A = Pe^(rt), where A is the amount of money at the end of the investment period, P is the principal amount invested, e is the mathematical constant approximately equal to 2.71828, r is the annual interest rate, and t is the time in years.

In this case, we know that the Davises want to contribute $9500 to their son's education in 12 years, the annual interest rate is 9.5%, and the interest is compounded continuously. We can use this information to solve for the principal amount they should invest now.

A = Pe^(rt)
9500 = P*e^(0.095*12)
9500 = P*e^1.14
P = 9500/e^1.14
P = 9500/3.125
P = $3040.00 (rounded to the nearest cent)

Therefore, the Davises should invest $3040.00 now at an interest rate of 9.5% per year, compounded continuously, in order to be able to contribute $9500 to their son's education in 12 years.

Find the components of a vector with magnitude 8 and a direction angle of 210°

Please have your answer be in coordinates.

Answers

The components of the vector with magnitude 8 and a direction angle of 210° are

(-4√3, -4)

How to find the components

To find the components of a vector with magnitude 8 and a direction angle of 210°, we can use the following formulas

x-component = magnitude * cos(angle)

y-component = magnitude * sin(angle)

given that:

magnitude = 8

angle = 210°

convert the angle from degrees to radians:

angle in radians = angle * π / 180

= 210° * π / 180

= 7π/6 radians

calculate the components:

x-component = magnitude * cos(angle in radians)

= 8 * cos(7π/6)

= 8 * (-√3/2)

= -4√3

y-component = magnitude * sin(angle in radians)

= 8 * sin(7π/6)

= 8 * (-1/2)

= -4

Therefore, the components of the vector with magnitude 8 and a direction angle of 210° are (-4√3, -4).

log 25 divided by log 3


log 25 over 3


fraction numerator log 25 over denominator log 3 end fraction


fraction numerator ln 25 over denominator ln 3 end fraction

Answers

The two expressions are not equivalent.

log 25 divided by log 3 is equal to log subscript 3 25.fraction numerator ln 25 over denominator ln 3 end fraction is not equal to log subscript 3 25.

The expression "fraction numerator log 25 over denominator log 3 end fraction" is equal to log 25 divided by log 3.

This is because the numerator represents the logarithm of 25 and the denominator represents the logarithm of 3, resulting in the ratio of the two logarithms.

On the other hand, the expression "fraction numerator ln 25 over denominator ln 3 end fraction" is not equal to log subscript 3 25. The numerator represents the natural logarithm (ln) of 25, and the denominator represents the natural logarithm of 3.

The natural logarithm uses the base e (2.71828), whereas the logarithm with subscript 3 uses the base 3.

Therefore, these two expressions are not equivalent.

log 25 divided by log 3 is equal to log subscript 3 25.

Andrew is an undergraduate researcher. He has hypothesized that the sediment on the bottom of University Lake at LSU contains more fecal coliforms (e.g., E. coli and others) than the sediment on the bottom of Lake Pontchartrain in Covington, LA or the sediment on the bottom of the Lake Martin near Lafayette, LA. He makes selective and differential agar that is specific for fecal coliforms. He inoculates the surface of the agar in a Petri dish for each of these 3 samples. He places 1 gram of sediment on the Lake Pontchartrain plate, 750 milligrams of sediment onto the University Lake plate, and 6.25 g of sediment onto the Lake Martin plate. He incubates the plates at 37 degrees Celsius, which is body temperature for humans. The next day he counts the fecal coliforms as CFU (colony-forming units).
