The slope of the graph of y = -3x is -3. The slope of a line is the amount that the line rises or falls for every unit it moves horizontally. In this case, the line rises by -3 units for every 1 unit it moves horizontally. This means that the slope of the line is -3.

The logistic model of the projected magazine sales is P = e¹⁰⁰⁰/1+e¹⁰⁰⁰

What is meant by logistic model?

In math, logistic model refers a statistical analysis method to predict a binary outcome, such as yes or no, based on prior observations of a data set.

Here we have given that our new magazine initially sells 400 copies per month. research indicates that a vigorous advertising campaign could increase sales by 30% each month if our market were unlimited. but research also indicates that magazine sales in our area are unlikely to exceed 2000 per month.

Here we need to make a logistic model of projected magazine sales.

As per the formula of logistic model, while we looking into the given question, we identified the values,

a = 400

x = 30% => 0.3

b = 2000

Then the logistic model of the given situation is written as,

=> P = e⁴⁰⁰⁺⁰°³ˣ²⁰⁰⁰/ 1 +  e⁴⁰⁰⁺⁰°³ˣ²⁰⁰⁰

=> P = e¹⁰⁰⁰/1+e¹⁰⁰⁰

Step-by-step explanation: To calculate Social Security tax for Betsy at $1,200, we need to find the amount of tax that is due on that amount of income. According to the schedule, Social Security tax is applied at a rate of 6.2% on income up to $128,400. Therefore, the amount of tax due on $1,200 of income would be $1,200 x 6.2% = $<<12006.2.01=74.4>>74.4.

To find the rate in still water, we need to find the average speed of the boat. The total distance traveled by the boat is 192 + 360 = 552 kilometers. The total time taken is 3 + 4 = 7 hours.

So, the average speed of the boat is 552/7 = 78.857 km/hr.

To find the rate of the current, we need to find the difference in speed between the upstream and downstream journeys. The difference in speed is 360/4 - 192/3 = 90 - 64 = 26 km/hr.

So, the rate of the current is 26 km/hr.

Therefore, the rate in still water is 78.857 km/hr and the rate of the current is 26 km/hr.

Suma= 80 + 160 + 80 + 40 + 20

Suma= 400

Step-by-step explanation:

The sum of the first five terms of the geometric progression is 1705.

To calculate the sum of the first five terms of a geometric progression, we need to determine the first term and the common ratio. Given that the third term is 80 and the ratio is 4, we can find these values.

In a geometric progression, each term is obtained by multiplying the previous term by the common ratio. Let's denote the first term as "a" and the common ratio as "r."

Given that the third term is 80, we can write the equation:

a * r² = 80

We are also given that the ratio is 4, so we have:

r = 4

Substituting this value of r into the equation, we get:

a * (4)² = 80

a * 16 = 80

16a = 80

a = 5

Now that we have determined the first term (a = 5) and the common ratio (r = 4), we can calculate the sum of the first five terms using the formula for the sum of a geometric series:

Sum = a * (1 - rⁿ) / (1 - r)

Plugging in the values, we have:

Sum = 5 * (1 - 4⁵) / (1 - 4)

Step-by-step explanation:

The Continuous Compound Interest Formula is derived from the Compound Interest Formula: [tex]A = P(1 + \frac{r}{n})^{nt}[/tex], as the number of times interest is applied, goes to infinity. Through some simple algebraic manipulation, we get the formula: [tex]A = Pe^{rt}[/tex] (e is known as Euler's Number and is notation for a constant value like [tex]\pi[/tex])

Since Valeria invested 770 in an account with an interest of 53% paying monthly, we want to find how much time it takes to triple her money, and then plug that into Zoey's equation.

So let's generally solve for time in the equation:

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

First divide by P

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

From here, it helps to take the base 10 log of both sides, so we can apply logarithmic properties, in this case we want to bring the exponent down.

[tex]log(\frac{A}{P}) = nt * log(1 + \frac{r}{n})[/tex]

Now from here' lets divide both sides by the log (the one on the right side) and "n" to give us:

[tex]\frac{log(\frac{A}{P})}{n * log(1 + \frac{r}{n})} = t[/tex]

Now whenever we need to calculate time, we simply need to plug in these values. We're given the following information from the problem:

[tex]P = 770\\r = 0.53\\n = 12\text{ compound monthly means 12 per year}\\A= 2,310 \text{ this is just 770 * 3, since we're looking for when Valeria's money triples}[/tex]

Plugging in the values we get:

[tex]\frac{log(\frac{2310}{770})}{12*log(1+\frac{0.53}{12}}=t[/tex]

Plugging this into a calculator, gives an approximate value of:

[tex]2.1183\approx t[/tex]

From here we simply need to plug values into the continuous compound interest formula: [tex]A=Pe^{rt}[/tex]

We're given the following information:

[tex]A = 770\\r= 0.03\\[/tex]

and we know that:

[tex]t\approx 2.1183[/tex]

since we solved for that.

So now let's just plug values into the equation!

[tex]A\approx 770 * e^{0.05 * 2.1183}\\A \approx 856.03[/tex]

So now we have our solution!

The equation of the parabola with focus (2, -1) and vertex (2, 5) is

[tex](x-2)^2[/tex]= -24(y - 5).

An equation of a parabola with focus ( 0, p ) and directrix y = − p is

[tex]x^2[/tex] = 4py, p < 0

Here, we have the focus = (2, -1) and vertex = (2, 5)

substituting the values in the above equation we get,

p = -1 - 5 = -6

hence, p = -6

now let us find the equation of the parabola as follows-

[tex](x-2)^2[/tex]= 4p(y - 5)

[tex](x-2)^2[/tex]= 4 (-6) (y - 5)

[tex](x-2)^2[/tex]= -24(y - 5)

3) Interest = P(1.039)^(t)

Balance = $487.91

4) Interest = 435e^(0.039t)

Balance = $488.99

We are given different formulas for interest and we are told to find the balance of each option after 3 years. Thus, we have;

1) P(1 + rt)

Where;

P is principal = $435

r is rate = 0.039

t is time = 3 years

We have;

Balance = 435(1 + (0.039 * 3))

Balance = $485.90

2) P(1 + (r/n))^(nt)

Where;

P is principal = $435

r is rate = 0.039

t is time = 3 years

n is number of times interest is compounded per year  = 1 (because it is yearly)

Thus;

A = 435(1 + (0.039/1))^(3 * 1)

A = $487.91

3) Same as 2 above

4) P₀e^(rt)

where;

P₀ is principal = $435

r is rate = 0.039

t is time = 3 years

Thus;

A = 435(e^(0.039 * 3)

A = $488.99
