A 39-foot ladder is leaning against a vertical wall. If the bottom of the ladder is being pulled away from the wall at the rate of 2 feet per second, at what rate is the area of the triangle formed by the wall, the ground, and the ladder changing, in square feet per second, at the instant the bottom of the ladder is 15 feet from the wall?

Answers

Answer:

The area of the triangle formed is increasing at a rate of 29.75 square feet per second.

Step-by-step explanation:

A 39-foot ladder is leaning against a vertical wall. We are given that the bottom of the ladder is being pulled away at a rate of two feet per second, and we want to find the rate at which the area of the triangle being formed is is changing when the bottom of the ladder is 15 feet from the wall.

Please refer to the diagram below. x is the distance from the bottom of the ladder to the wall and y is the height of the ladder on the wall.

According to the Pythagorean Theorem:

[tex]\displaystyle x^2+y^2=1521[/tex]

Let's take the derivative of both sides with respect to time t. Hence:

[tex]\displaystyle \frac{d}{dt}\left[x^2+y^2\right] = \frac{d}{dt}\left[ 1521\right][/tex]

Implicitly differentiate:

[tex]\displaystyle 2x\frac{dx}{dt} + 2y\frac{dy}{dt} = 0[/tex]

Simplify:

[tex]\displaystyle x\frac{dx}{dt} + y \frac{dy}{dt} = 0[/tex]

The area of the triangle formed will be given by:

[tex]\displaystyle A = \frac{1}{2} xy[/tex]

Again, let's take the derivative of both sides with respect to time t:

[tex]\displaystyle \frac{dA}{dt} = \frac{d}{dt}\left[\frac{1}{2}xy\right][/tex]

From the Product Rule:

[tex]\displaystyle \frac{dA}{dt} = \frac{1}{2}\left(y\frac{dx}{dt} + x\frac{dy}{dt}\right)[/tex]

At that instant, the ladder is 15 feet from the base of the wall. So, x = 15. Using this information, find y.

[tex]\displaystyle y = \sqrt{1521-(15)^2}=36[/tex]

The bottom of the ladder is being pulled away from the wall at a rate of two feet per second. So, dx/dt = 2. Using this information and the first equation, find dy/dt:

[tex]\displaystyle \frac{dy}{dt} =-\frac{x\dfrac{dx}{dt}}{y}[/tex]

Evaluate for dy/dt:

[tex]\displaystyle \frac{dy}{dt} = -\frac{(15)(2)}{(36)}=-\frac{5}{6}[/tex]

Finally, using dA/dt, substitute in appropriate values:

[tex]\displaystyle \frac{dA}{dt} = \frac{1}{2}\left((36)(2)+(15)\left(-\frac{5}{6}\right)\right)[/tex]

Evaluate. Hence:

[tex]\displaystyle \frac{dA}{dt} = \frac{119\text{ ft}^2}{4\text{ s}} = 29.75\text{ ft$^2$/s}[/tex]

The area of the triangle formed is increasing at a rate of 29.75 square feet per second.

Answers

Answer:

[tex](\frac{f}{g})(x) = \frac{x- 3}{2x + 1}[/tex]

Step-by-step explanation:

Given

[tex]f(x) =x^2 -x - 6[/tex]

[tex]g(x) = 2x^2 + 5x + 2[/tex]

Required

[tex](\frac{f}{g})(x)[/tex]

This is calculated as:

[tex](\frac{f}{g})(x) = \frac{f(x)}{g(x)}[/tex]

So, we have:

[tex](\frac{f}{g})(x) = \frac{x^2 - x - 6}{2x^2 + 5x + 2}[/tex]

Expand

[tex](\frac{f}{g})(x) = \frac{x^2 +2x - 3x - 6}{2x^2 + 4x+x + 2}[/tex]

Factorize

[tex](\frac{f}{g})(x) = \frac{x(x +2) - 3(x + 2)}{2x(x + 2)+1(x + 2)}[/tex]

Factor out x + 2

[tex](\frac{f}{g})(x) = \frac{(x- 3)(x + 2)}{(2x + 1)(x + 2)}[/tex]

Cancel out x + 2

[tex](\frac{f}{g})(x) = \frac{x- 3}{2x + 1}[/tex]

Answers

Answer:

The y-coordinate of point A is [tex]\sqrt{3}[/tex].  

Step-by-step explanation:

The equation of the circle is represented by the following expression:

[tex](x-h)^{2}+(y-k)^{2} = r^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]h[/tex], [tex]k[/tex] - Coordinates of the center of the circle.

[tex]r[/tex] - Radius of the circle.

If we know that [tex]h = 0[/tex], [tex]k = 0[/tex] and [tex]r = 2[/tex], then the equation of the circle is:

[tex]x^{2} + y^{2} = 4[/tex] (1b)

Then, we clear [tex]y[/tex] within (1b):

[tex]y^{2} = 4 - x^{2}[/tex]

[tex]y = \pm \sqrt{4-x^{2}}[/tex] (2)

If we know that [tex]x = 1[/tex], then the y-coordinate of point A is:

[tex]y = \sqrt{3}[/tex]

The y-coordinate of point A is [tex]\sqrt{3}[/tex].

D. Inflation

Answers

Answer:

deflation ,,,,

Step-by-step explanation:

I hope it's helpful for you ☺️

Deflation must have existed during the second 9-year period.

What is deflation?

Deflation is a decrease in the general price level of goods and services in an economy over a period of time. This means that the purchasing power of money increases, as the same amount of money can buy more goods and services.

The opposite of inflation, which is an overall rise in the cost of goods and services over time, is deflation. Money loses value due to inflation, whereas it gains value due to deflation. Deflation can reduce demand for goods and services, though, if it lasts for a long time. This is because customers may put off purchases in expectation of cheaper costs. A downturn in economic activity may follow, which would be bad for the economy.

Given data ,

Deflation is a decrease in the general price level of goods and services in an economy over a period of time. A decrease in the Consumer Price Index (CPI) is a measure of deflation.

In the first 9-year period, the CPI decreased by 45%, which indicates a significant deflationary period. In the next 9-year period, the CPI decreased by only 5%, which still indicates a deflationary period, but not as severe as the previous one.

Hence , the process is deflation in the second year

Answer:

[tex]\text{b. } y=-(x-3)^2+4[/tex]

Step-by-step explanation:

Algebraically, we want to compare the y-coordinates of the vertex, since all the functions shown are parabolas that are concave down.

Let's break the format down:

The negative sign in front of each of the functions indicate that the parabolas will be concave down (open downwards), which means the vertex represents the function's maximum. The term inside the parentheses when applicable to just indicates the horizontal/phase shift.

Since the first term being squared is negative, we want to minimize its value to produce the greatest possible y-value.

Therefore, substitute whatever value of [tex]x[/tex] that makes each [tex]x^2[/tex] term equal to 0. (Maximum value of [tex]-x^2[/tex] is 0).

Therefore, we can simplify compare the last terms in each equation.

Equation A's last term is 3.

Equation B's last term is 4.

Equation C's last term is -5.

Equation D's last term is 0.

Since equation B has the greatest last term, it will have the greatest possible y-value.

Find the percentile rank for each test score in the data set. 12, 28, 35, 42, 47, 49, 50 What value corresponds to the 60th percentile

Answers

Answer:

Percentile rank:

12  =  7th

28 = 21st

35  = 36th

42  = 50th

47  = 64th

49   = 79th

50 =  93rd

- Vth number i.e. 47 is the value that corresponds to the 60th percentile.

Step-by-step explanation:

As we know,

Percentile rank = [(Number of values below x) + 0.5]/total number of values * 100

For 12,

Percentile rank = [0 + 0.5]/7 * 100

= 7th

For 28,

Percentile rank = [1 + 0.5]/7 * 100

= 21st

For 35,

Percentile rank = [2 + 0.5]/7 * 100

= 36th

For 42,

Percentile rank = [3 + 0.5]/7 * 100

= 50th

For 47,

Percentile rank = [4 + 0.5]/7 * 100

= 64th

For 49,

Percentile rank = [5 + 0.5]/7 * 100

= 79th

For 50,

Percentile rank = [6 + 0.5]/7 * 100

= 93rd

Now,

n = 7

60th percentile = 60% of n

So,

60% of n = 60/100 * 7

= 0.6 * 7

= 4.2

After rounding it off,

5th value is the 60th percentile i.e. 47.

A Bee MysteryRecent surveys around the world have found some very sad and troubling news. Bees are not doing well. According to Time: Science & Space, "an estimated ten million beehives ... have been lost since 2006." What's worse, scientists are not sure why. Most beekeepers will tell you that bees tend to die in large numbers every spring. This is normal and necessary to keep a hive of bees healthy. But when the deaths add up to more than half the bees in an entire country, that is something altogether different and dire. Scientists have called this "colony-collapse disorder" or CCD. This name describes the effect, though, and not the cause of the die-out. Scientists simply do not know what is killing the bees.Many things make it hard for bees. Varroa mites move into a colony and weaken it. Further, these mites carry viruses that attack those that survive. In addition, a new bacterium was recently discovered that attacks bees intestinally and kills them. Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. All these attackers and the methods used to combat them do stress the bees, however.Many feel the problem is not some new threat, but a decline in the habitat available to bees. Development of grasslands once home to wild flowers and food for bees has been universal. Pavement makes it easy to drive, but it replaces wild grasses and other food sources for bees. Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health. We plowed under a varied habitat and plantedin many casesa single plant like beets. Then we sprayed all kinds of chemicals on the beets to keep other bugs away and in doing so also harmed bees. Now, to treat all the mites and other invaders, bee keepers use additional chemicals to kill the invaders. These chemicals also shorten the life of the bees. Have the use of chemicals, loss of habitat, and invading parasites made life impossible for bees? Experts continue to argue various theories, but few have any answers.Colony collapse disorder is perhaps one of the most mysterious problems modern science has tried to solve. Whether the problem is environmental or an unknown disease, we will all feel the effects if bees continue to decline. Bees affect almost every aspect of the human food chain. From the fruits, vegetables, and grains we eat, to the grasses and grains we feed our livestock, we depend on bees to keep us healthy. According to the Natural Resources Defense Council, bees account for 15 billion dollars in crops. Honey is a treasure for sure, but the real gold is in the strawberries, apples, peaches, and green beans we eat and need to stay healthy ourselves. All told, the outlook for bees is not good. The outlook for humans may not "bee" so good either.Read this sentence from the text:Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health.How does this line function in the text?
