Answer:

y = -6

Step-by-step explanation:

We know the formula for slope is:

m = ( y2-y1)/(x2-x1)

We are given the two points using a variable and the slope.

-8 = (2-y)/(3-4)

-8 = (2-y)/(-1)

Multiply each side by -1.

8 = 2-y

Subtract 2 from each side.

8-2 = 2-y-2

6 = -y

Multiply by -1.

-6 =y

Answer:

y = -6

Step-by-step explanation:

The formula to find the slope is:

[tex]m = \frac{y_1 - y_2}{x_1-x_2}[/tex]

Given that,

( 4, y ) ⇒ ( x₁ , y₁ )

( 3, 2 ) ⇒ ( x₂ , y₂ )

m ( slope ) = -8

Accordingly, we have to find the value of y₁.

Let us find it now by making y₁ the subject.

[tex]\sf m = \frac{y_1 - y_2}{x_1-x_2} \\\\-8 = \frac{y_1 - 2}{4-3}\\\\-8 = \frac{y_1 - 2}{1}\\\\Multiply\:\:Both\:\:sides\:\:by\:\:1.\\\\-8=y_1-2\\\\Add \:\:2\:\:to\:\:both\:\:sides.\\\\-8+2=y_1\\\\-6=y_1=y[/tex]

Based on exponential growth, city with a population of 700,000 growing at an annual rate of 7% will be 2,898,394 in 21 years.

Exponential growth refers to an increase where a constant proportional amount is added to the initial value.

Exponential growth function can be modeled as follows:

f(x)=a(1+r)ˣ

Where:

f(x) = exponential growth function

a = initial amount

r = growth rate

{x} = number of time intervals

The current population of the city, a = 700,000

The annual growth rate, r = 7% = 0.07

The number of time intervals, x = 21 years

The population in 21 years = 700,000 x (1 + 0.07)²¹

= 700,000 x (1.07)²¹

= 700,000 x 4.14056237

= 2,898,394

Thus, using an exponential growth rate, the population of the city will grow to 2,898,394 after 21 years.

If the diagonals of rectangle QRST intersect at P, given that m<PTS = 34° and QS=10, QP is:

34.9°

The diagonals of a rectangle bisect each other. Therefore, the angle at P can be split into two equal angles, each measuring (m<PTS)/2

= 34°/2

= 17°.

Since QP is the hypotenuse of a right triangle with angles 17° and 63° (the sum of the angles in a rectangle is 180°), we can use the tangent function to find QP:

Where k is the proportionality constant.

Given that;

First, we determine the proportionality constant.

R = k/A

12 = k/1.5

k = 18

Now, the value of A when R = 9 will be;

R = k/A

A = k/R

One possible equation to model the population of foxes, P, as a function of time, t, in years, based on the information provided, is:

This equation uses a sinusoidal function with a period of 2.2 years (the time between minimum and maximum values) and an amplitude of 400 (the difference between minimum and maximum values).

The phase shift of 2.9 years is also incorporated, so that the minimum value of 200 foxes occurs at t = 2.9 years. The vertical shift of 500 was added to ensure that the maximum value of 800 foxes is achieved.

Given the class width of 6 and the minimum value of 12, the maximum value in the first class would be 12 + 6 - 1 = 17. The maximum value in the 6th and last class would be 17 + (6 x 5) = 42. Hence, the largest possible value in the data set is '42'.

A frequency table is used to organize and represent the distribution of a set of data. In this case, the data set has 6 classes and a class width of 6. This means that the range of values in each class is 6 units. The minimum value in the data set is 12, so the first class starts at 12 and ends at 12 + 6 - 1 = 17. This is because the class width is 6, so the end value of the first class would be the starting value plus the class width minus 1.

For the last class, the end value would be 17 + (6 x 5) = 42. This is because the end value of the first class is 17 and each subsequent class increases by 6 units. The largest possible value in the data set would be the end value of the last class, which is 42. This means that any value greater than 42 would not be part of the data set and would not be included in the frequency table.

Here, we are required to determine at what value of x for x>0 does the line tangent to the graph of f at x have slope 2 of a function

x = 2.29

A line tangent to the graph of f is given by the derivative of the function, f (i.e f')

However, this derivative has been provided in the question as function

f′(x)=0.1x+e(0.25x).

The line tangent to the graph of f will therefore have a slope of 2 at point f′(x) = 2

Therefore, since f′(x) = 2 and f′(x)=0.1x+e(0.25x)

We can then say; 2 = 0.1x + e(0.25x).

This evaluation can then be carried out by the use of a graphing calculator and the value of x (for x > 0) is gotten to be;

Answer:

The value of k for which one root of the quadratic equation kx2 -14x+8=0 is six times the other is k = 2.

Step-by-step explanation:

The constant is [tex]$y_0$[/tex] and the function is [tex]$y(t) = 4e^{-2t} + 2t - 9$[/tex].

The unique solution to the given initial value problem can be expressed as:

[tex]\begin{align}y(t) = 4e^{-2t} + 2t - 9 + y_0\end{align}[/tex][tex]\begin{align}y(t) = 4e^{-2t} + 2t - 9 + y_0\end{align}[/tex][tex]y(t) = 4e^{-2t} + 2t - 9 + y_0\end{align}[/tex]

where the constant is [tex]$y_0$[/tex] and the function is [tex]$y(t) = 4e^{-2t} + 2t - 9$[/tex].

To calculate the constant and the function, we solve the differential equation [tex]$y' = g(t)$[/tex] with the initial condition [tex]$y(0) = y_0$[/tex]. We start by differentiating both sides of the equation and rearranging to get the differential equation:

[tex]y' = g(t) \implies \frac{dy}{dt} = 4e^{-2t} + 2\end{align}[/tex]

Integrating both sides and using the initial condition gives us:

[tex]\int \frac{dy}{dt} dt &= \int (4e^{-2t} + 2)dt \\y &= 4e^{-2t} + 2t + c \\y(0) &= 4e^{-2(0)} + 2(0) + c \\y_0 &= 4 + c \\y(t) &= 4e^{-2t} + 2t - 9 + y_0\end{align}[/tex]

Therefore, the constant is [tex]$y_0$[/tex] and the function is [tex]$y(t) = 4e^{-2t} + 2t - 9$[/tex].

Interest is a fee charged by a lender to a borrower for the use of money. It is a percentage of the principal amount (the amount borrowed) that is added to the principal over a specified period of time. The interest rate is the rate at which the interest is calculated, and it is typically expressed as an annual percentage rate (APR).

For example, if you borrow $1000 at an interest rate of 5% per year, the interest charge for one year would be $50 ($1000 * 5%). The interest and the principal form the total amount that must be repaid at the end of the loan term.

Interest can be charged on loans, such as personal loans, mortgages, and car loans, as well as on savings accounts and other investments. The purpose of charging interest is to compensate the lender for the opportunity cost of not having access to the funds during the loan term.

Let's calculate the interest charge for each bank:

For State Savings and Loan:

Interest = 2600 * 7.25% * 90/365 = $121.44

For Security Bank:

Interest = 2600 * 7.5% * 90/365 = $122.62

So, Security Bank is charging higher interest and is not a better deal.

If Lady GaGa chooses State Savings and Loan, she will save:

Adding and subtracting fractions with unlike denominators involves finding a common denominator, which is the least common multiple of the denominators of the fractions.

Once you have found the common denominator, you can convert each fraction so that it has the same denominator, and then you can add or subtract the numerators to find the final answer.

Here's an example word problem:

A baker has 3/4 of a bag of flour and 1/2 of another bag of flour. How much flour does the baker have in total?

To solve this problem, we need to find a common denominator for 3/4 and 1/2. The least common multiple of 4 and 2 is 4, so we can use 4 as the common denominator. We then convert each fraction so that it has a denominator of 4:

3/4 = (3 x 4) / (4 x 1) = 12/4

1/2 = (1 x 2) / (2 x 1) = 2/4

Now that both fractions have the same denominator, we can add their numerators to find the total:

12/4 + 2/4 = 14/4 = 3 1/2

So, the baker has 3 1/2 bags of flour in total.
