The cost of the jersey that Charlotte wanted to buy  who is visiting to Brazil, in U.S. dollars based on the exchange rate is $16.39.

What is the exchange rate?

The exchange rate is the rate at which two nations currencies are exchanged in the foreign exchange market.

The exchange rate depends on the purchasing power of each currency.

Data and Calculations are as follows :

Cost of jersey = Br. 89

Exchange rate = $1 : Br. 5.43

Cost of jersey in US dollars = $ (Br. 89/Br. 5.43)

Thus, the cost of the jersey that Charlotte in U.S. dollars based on the exchange rate is B. $16.39.

Answer:

A and E

Step-by-step explanation:

The geometric series which has the common ratio 2 is 0.0625, 0.125, 0.25, 0.5, 1, … thus option (C) is correct.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given,

Common ratio r = 2

Common ratio = next term / previous term

In the series 0.0625, 0.125, 0.25, 0.5, 1, … the common ratio is 2.

In the series [tex]a_{n}[/tex] = (1/2) × [tex]a_{n-1}[/tex]

a₁ = 2 so

a₂ = (1/2)a₁ 1

The ratio is 1/2, not 2.

Hence "The geometric series which has the common ratio 2 is 0.0625, 0.125, 0.25, 0.5, 1, …".

The steps of the analytical problem-solving model include: identifying the problem, exploring alternatives, building an implementation plan, implementing a solution, and evaluating the situation.

Analytical problem solving, as we've defined it above, refers to the approaches and methods you use rather than the particular issue you're trying to resolve.

Analytical issue solving is a crucial prerequisite for problem resolution; the problem itself does not determine whether you need it.

Analytical problem solving involves recognising a problem, investigating it, and then creating ideas (such as causes and solutions) around it.

Solving analytical problems calls for inquiry, examination, and analysis that encourages additional study of the subject (including causality, symptoms, and solution).

The correct option; y = negative x + 5 is the a side perpendicular to side s's equation.

Using (4,1) as the line s's coordinate, and (1,4).

Obtain this line's equation;

Slope m = 4 - 1 / 1 - 4

Slope m = 3/-3

m = -1

Using, y - y0 = m(x - x0)

Add any point, like (4, 1), and m = -1 to the equation above;

y - 1 = -1(x - 4)

y - 1 = -x + 4

y + x = 4 + 1

y + x = 5

y = -x + 5

Thus, y = negative x + 5 is the a side perpendicular to side s's equation.

The equation of the tangent would be y = -4x/3 - 25/3 and the equation of the normal would be y = 3x/4.

What is a parabola?

A parabola is a plane curve that is mirror-symmetrical and roughly U-shaped in mathematics. It fits several seemingly disparate mathematical descriptions, all of which can be shown to define the same curves. A point and a line are two ways to describe a parabola.

The given equation is x² + y² = 25 ; (4, 3)

Now when we put x = 4 and y = 3

then LHS = RHS.

Now find the slope:

      2x + yy' = 0

       ⇒ y' = -x/y

Now at (4, 3) slope would be y' = -4/3.

The equation of the tangent would be

      y - y1 = m(x - x1)

      y - 3 = (-4/3)(x-4)

     3y - 9 = -4x + 16

     4x + 3y = 25

     y = -4x/3 - 25/3

Now equation of the normal is:

  y - y1 = (-1/m)(x - x1)

  y - 3 = 3/4(x - 4)

  y = 3x/4

Hence, the equation of the tangent would be y = -4x/3 - 25/3 and the equation of the normal would be y = 3x/4.

The probability that no more than three are enrolled in college or university is P(x≤3)=(C⁵ₓ(0.63)ˣ(0.37)⁵⁻ˣ

Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true. The probability of an event is a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.

When we are confused about the outcome of an event, we might discuss the probabilities of certain outcomes—how likely they are. Statistics is the study of events that are guided by probability.

Probability (P) = 0.63

There are 7nickels, 13dimes and 15quarters of coins which the Cashier has using algebra.

We first represent the the value of nickels with an unknown value x, and then the values of dimes and quarters in are expressed in terms of x. then multiply each derived number of coins with their value in cents and equate them to their total of 540cents converted from $5.40.

A nickel = 5cents, a dime = 10cents, a quarter = 25cents and $5.40 = 540cents

Let the number of nickel coins be represented by x, hence there are (2x - 1) dimes and (36 - 3x) quarters.

Thus we have;

x nickel = 5x cents

(2x - 1) dimes = 10(2x - 1)cents

(36 - 3x) quarters = 25(36 - 3x)cents

5x + 10(2x - 1) + 25(36 - 3x) = 540

5x + 20x - 10 + 900 - 75x = 540 {collect like terms}

75x - 25x = 350

50x = 350

x = 350/50

x = 7

Therefore, there are 7nickels, [2(7) - 1] = 13dimes, and [36 - 3(7)] = 15quarters by substituting 7 for x from our derived value of coins

The population of the city grew most rapidly in the year 1988.

Given, the population of a city is modeled by a function

P(t) = 250/(1 + 480e^-0.8t)

we have to find that when the population is growing most rapidly.

On differentiating, we get

P'(t) = 250/(1 + 480e^-0.8t)²×(-384e^-0.8t)

Again differentiating we get

P''(t) = 96000(e^-1.6t)(-0.8e^-0.8 + 384)

Putting P''(t) = 0, we get

e^0.8t = 0

t = 8

So, the population of the city grew most rapidly in the year (1980 + 8) = 1988.

The days that must elapse for a sample of neptunium-239 to decay to 0.0100% of its original quantity is calculated to be 31.33

The equation for radioactive decay in this case can be given as

N = N₀exp(-λt)

To determine the decay constant, λ, we have;

λ = -(lnN/N₀)/t    

here

t illustrates the half-life of Neptunium-239 which is equal to 2.35 days

N/N₀ = 1/2 where N represents the Quantity of Neptunium-239 after half-life and N₀ represents the initial quantity of Neptunium-239

Therefore, λ = -(ln(1/2)) ÷ 2.35

λ = 0.294/day.

Now for Neptunium-239 to decay to 0.0100 % of its initial value,

N/N₀ × 100 % = 0.0100%

N/N₀ = 0.0100 / 100

N/N₀ = 0.0001

From the equation for radioactive decay, we determine the time it takes for 239np to decay to this value as follows;

t = -(lnN/N₀)/λ = -(ln(0.0001))/0.294/day = 31.33 days
