Answer 1

(a) An equation for the (non-zero) vertical (x -)nullcline of this system is  and for the (non-zero) horizontal (y-)nullcline is y = 1 - x/3 and x = 1 - y/4

(b) The equilibrium points for the system are (0,0) and (1,1).

c) If we start at the initial position (2,2), trajectories approach the point (1,1).

The system of equations we will consider is:

dx/dt = x(1 - x/3 - y)

dy/dt = y(1 - y/4 - x)

To find the vertical (x-)nullcline, we set dx/dt to 0 and solve for y. This gives us:

1 - x/3 - y = 0

y = 1 - x/3

Similarly, to find the horizontal (y-)nullcline, we set dy/dt to 0 and solve for x. This gives us:

1 - y/4 - x = 0

x = 1 - y/4

The nullclines represent the points in the phase plane where either dx/dt or dy/dt is zero.

Therefore, any trajectory that passes through a nullcline will be tangent to that nullcline.

To find the (non-zero) vertical (x-)nullcline, we set x = 0 and solve for y. This gives us y = 1/x.

Therefore, the equation of the vertical nullcline is y = 1/x.

Similarly, to find the (non-zero) horizontal (-)nullcline, we set y = 0 and solve for x. This gives us x = y.

Therefore, the equation of the horizontal nullcline is x = y.

Next, we want to find the equilibrium points of the system, which are the points in the phase plane where both x and y are zero.

To find the equilibrium points, we set x = 0 and y = 0 and solve for x and y. This gives us two equilibrium points: (0,0) and (1,1).

To confirm that these are indeed equilibrium points, we can substitute them into the original equations and verify that x and y are both zero at these points.

Finally, we want to estimate trajectories in the phase plane using a phase plane plotter.

Suppose we start at the initial position (2,2). We can use the phase plane plotter to draw the trajectory that passes through this point. We observe that the trajectory approaches the equilibrium point (1,1) as t goes to infinity.

Therefore, we can complete the sentence as follows: If we start at the initial position (2,2), trajectories approach the point (1,1).

Jimmy invests $2500 in an account with a 5% interest rate, making no other deposits or withdrawals. What will Jimmy’s account balance be after 8 years if the interest is compounded 6 times each year?
URGENT PLEASE

Answers

Answer:

We conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.

Step-by-step explanation:

Given

Principle P = $2500

Interest rate r = 5% = 0.05

Time period t = 8 years

To determine

Accrue Amount A = ?

Using the compound interest equation

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

where:

A represents the Accrue Amount

P represents the Principal Amount

r represents the interest rate

t represents the time period in years

n represents the number of compounding periods per unit t

Important tip:

Given that the interest is compounded 6 times each year, therefore, the value of n = 6.

now substituting P = 2500, r = 0.05, t = 8 and n = 6 in the equation

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

[tex]A=2500\left(1+\frac{0.05}{6}\right)^{\left(6\right)\left(8\right)}[/tex]

[tex]\:A=2500\left(1+\frac{0.05}{6}\right)^{48}[/tex]

[tex]A=2500\times 1.48935[/tex]      ∵  [tex]\left(1+\frac{0.05}{6}\right)^{48\:\:}=1.48935[/tex]

[tex]A=\:3723.38[/tex] $

Therefore, we conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.

Such a card has a reward rate - the percentage of money the user gets back as rewards for each charge transaction. The rewards are accumulated until used. When rewards are used, the accumulated reward amount is deposited into the card and accumulated reward amount is reset to zero. A ChargeCard must support the following calling syntaxes:ConstructorThe constructor should accept two required parameters, designating the spending limit on the card and the reward rate (as a float). Additionally, the constructor must accept an optional parameter that designates an initial balance (with the balance being 0 by default). For example, the syntax# using default value of balancecard = RewardsChargeCard(1000, 0.01)would create a new card, with spending limit of 1000, reward rate of 0.01, and an initial balance of zero.# specifying the value of balance explicitlycard = RewardsChargeCard(1000, 0.01, 100)would create a new card, with a spending limit of 1000, reward rate of 0.01, and an initial balance of 100.charge(amount)The RewardsChargeCard should override the parent class implementation of this method by:First calling the parent class implementation ofcharge(amount)Updating the value of accumulated rewards. Each charge transaction earns (amount * reward rate) toward the accumulated rewards. Rewards will only be added on valid transactions (if the charge is accepted).Returning True if the amount does not exceed the sum of the current card balance and the card limit, and False otherwise.For example, the following operations would result in the accumulated reward value 10.card=RewardChargeCard(10000, 0.01)card.charge(1000)If the charge is invalid (over the limit) the rewards are not added. For example, the following operations would result in no rewardscard = RewardChargeCard(10000, 0.01, 1000) # inital balance is 1000card.charge(10000) # charge is over the limit+balance, invalid operation, no rewardsgetRewards()A call to this method returns the value of accumulated rewards.useRewards()A call to this method applies the currently accumulated rewards to the balance and then sets the rewards total to 0. Applying rewards to the balance is identical to depositing money to the card, and a convenient way to apply accumulated rewards to the balance is by using the parent class deposit(amount) method and then setting the reward total to 0.To help you test your implementation of RewardsChargeCard, we provide you with a sample session that uses the RewardsChargeCard class:from RewardsChargeCard import RewardsChargeCard# spending limit of 10000, reward rate 0.03, initial balance 0visa = RewardsChargeCard(10000, 0.03)# returns True, as charge is accepted; new balance is 100.# accumulated reward value is 3visa.charge(100)# return value of 3.0 is displayedprint(visa.getRewards())# new balance is 1100# accumulated 30 for this transaction# total accumulated reward value is 33visa.charge(1000)# return value of 33.0 is displayedprint(visa.getRewards())# balance is adjusted to 1067# accumulated reward value is set to 0visa.useRewards()# return value of 1067.0 is displayedprint(visa.getBalance())# return value of 0 is displayedprint(visa.getRewards())# return False, as the amount we are charging is larger than the limit# no rewards should be addedvisa.charge(100000)# return value of 0 is displayedprint(visa.getRewards()) Additionally, we provide you with TestRewardsChargeCard.py script that uses Python unittest framework.

Their mom was unpacking kitchen stuff, and the boys had grown tired of hearing her exclaim every time she unwrapped another of the teapots she hadn't seen in months."You'd think she'd have enough teapots by now," said James."Yeah," said Noel, "I don't get that excited about my Godzilla collection and that is way more interesting than any teapot.""And I'm sorry," said James, "but I know way too much about teapots for a boy my age."James then started listing all the things he knew about teapots. "There's the spout and the pouring angle," he began. But Noel had already tuned James out. The heat was rising and as tired as he was of his mother's teapots, he was more tired of James' complaining.Besides, there was a raggedy old dog down the street. Noel could tell, even from far away, this was a dog that belonged to no one. Its coat was matted. It had no collar. All he could see of the dog's face was its nose sticking out. Its coat was all brown, but a dirty, grayish brown, not the deep dark warm brown that made you feel safe."And there's that teapot with the flowers. The brown one with the little dots all in a row," James continued on his rant, now listing all the teapots he had unwrapped for Mom. Noel continued ignoring James and watched the dog.It was moving slowly in their general direction. It stopped at various spots along the curb to smell things. Sometimes the smelling took a very long time. Every now and then it would sit down to scratch behind its ear. Noel wondered if it was looking for something to eat.James jabbered on and Noel began to wonder how a dog came to be in such a sad condition as this one. Did no one ever want it? Even as a puppy, was this fellow not cute enough to find a good family? Had it always been this ugly? Hadn't anyone ever been kind to it? The dog was across the street now, one house over. It seemed to be particularly attracted to mailboxes and the plants around them. To Noel's mind, it appeared that the dog was greeting each family on the street.Noel watched the dog cross the street heading in their direction. He hadn't noticed it before, but the dog's head seemed rather large. It swung back and forth in front of its body, much like the bears Noel had seen at the zoo and on television. Noel could not see any eyes through all the matted hair. He could see gnats and flies hovering over the poor thing, waiting for it to sit down again.It lumbered toward them. Noel noticed that James had stopped talking. He looked over at his brother. Staring at the dog, James seemed to be a bit shocked or surprised, maybe even stunned."What is that?" James whispered.Instead of sniffing their mailbox and moving on like before, the dog started up the sidewalk toward the steps where they were sitting. Noel could hear the flies buzzing and see not just a few gnats, but a whole swarm around the dog. Bits of leaves and twigs hung in its hair. The dog continued toward them. Was it going to stop, wondered Noel. Should I get up and get in the house? But then, just when Noel felt a twinge of panic, the dog sat down, wagged its tail, and smiled.

In these days we can kindle a fire without any trouble,because we can easily get a match; but we must remember that the match is one of the mostwonderful things in the world, and that it took men thousands of years to learn how to make one.Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboringvolcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In theearly history of the world, nature had to kindle all the fires, for man by his own effort was unable toproduce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flamekindled by nature-by a volcano, perhaps, or by a stroke of lightning. These firebrands were carried tothe home and used in kindling the fires there. The fire secured in this way was carefully guarded andwas kept burning as long as possible. But the flame, however faithfully watched, would sometimesbe extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrandwould have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate ofpotash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggisthad discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemicalbecause it is made by mixing certain chemicals together and rubbing them. Although Walker's matchidid not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hardrubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus wassubstituted on the tip for antimony, and the change worked wonders. The match could now belighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rubit. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This wasthe phosphorus match, the match with which we are so familiar,How does the author develop the idea that relying on nature was problematic?
