(-8, 1) and a directrix of y=-1. What
can be said about the parabola?

( , ) has a p-value of ( )
and it

Answers

We can say about the parabola given a focus of (-8, 1) and a directrix of y = -1 is as:

The parabola is a vertical parabola and facing up.The vertex of the parabola is v(-8, 0).p value of the parabola is 1.

A parabola refers to the shape that traces the equation of the form ax² + bx + c.

A parabola's directrix is a vertical or horizontal line that never contacts the parabola and is located at p distance from the vertex and 2p distance from the focus.

The parabola created when the directrix is on the y coordinate called a vertical parabola.

If the directrix value is greater than the corresponding focus or vertex, there will be a negative p and the parabola will face downhill.

If the directrix value is less than the corresponding focus or vertex, there will be positive p and the parabola will face up.

From the given definition of the directrix, we can find the value of p;

2p = y coordinate of focus - equation of the directrix

2p = 1 - (-1)

2p = 2

p = 1

Vertex, v(h, k) compared with f(h, k + p), we will get;

k + p = 1

k = 0

Therefore, the vertex is (-8, 0).

Thus, we can say about the parabola given a focus of (-8, 1) and a directrix of y = -1 is as:

The parabola is a vertical parabola and facing down.The vertex of the parabola is v(-8, 0).p value of the parabola is 1.

if k is a positive integer, find the radius of convergence, r, of the series [infinity] (n!)k 2 ((k 2)n)! xn n = 0 .

Answers

The radius of convergence of the given series can be found using the ratio test. The ratio test states that if lim |an+1/an| = L, then the series converges absolutely if L < 1 and diverges if L > 1. If L = 1, the test is inconclusive.

Applying the ratio test to the given series, we have:

=lim \(|((n+1)!)^k * 2 * ((k^2)(n+1))! * x^(n+1)| / |(n!)^k * 2 * ((k^2)n)! * x^n|\)

= lim \(|(n+1) * 2 * (k^2)(n+1) * x| / (k^2 * (n+1) + k^2n)\)

= lim\(|2x(k^2)(n+1)| / (k^2(n+1) + k^2n)\)

= lim\(|2x(k^2)| / k^2\)

= 2|x|

Therefore, the series converges absolutely if 2|x| < 1, or |x| < \(\frac{1}{2k^2.}\) Thus, the radius of convergence is r = \(\frac{1}{2k^2}\). In summary, the radius of convergence of the given series [infinity] (n!)k 2 ((k 2)n)! xn n = 0 is r =\(\frac{1}{2k^2.}\), which can be found using the ratio test.

Divide f(x) by g(x) using long division and write the result using the division algorithm. Please help!

Divide f(x) by g(x) using long division and write the result using the division algorithm. Please help!

Answers

To use long division in polynomials, we follow steps similar to normal long division, but we look for the terms from higher degree to lower.

We are dividing:

\(4x^3-7x^2+3\)

By:

\(2x-1\)

We want to multiply the divisor by some expression that will make the higher term equal to the higher term of the dividend. The higher term of the dividend is 4x³, to get to that, we can multiply the divisor by 2x²:

\(2x^2(2x-1)=2x^2\cdot2x-2x^2=4x^3-2x^2\)

Now we have the same term, so we just substract what we have got from the dividend:

\(\begin{gathered} 4x^3-7x^2+3 \\ -(4x^3-2x^2) \\ \\ 4x^3-4x^3-7x^2+2x^2+3 \\ -5x^2+3 \end{gathered}\)

Notice that we don't have a third degree term anymore.

So, until now we have done:

- Multiplied the divisor by 2x²

- Got a remainder of -5x² + 3

Now, we just repeat with the remainder.

We want to multiply 2x - 1 so that the higher term is -5x², so we can multiply by -5x/2:

\(-\frac{5x}{2}(2x-1)=-\frac{5x\cdot2x}{2}+\frac{5x}{2}=-5x^2+\frac{5x}{2}\)

And we do the substraction:

\(\begin{gathered} -5x^2+3 \\ -(-5x^2+\frac{5x}{2}) \\ \\ -5x^2+5x^2-\frac{5x}{2}+3 \\ -\frac{5x}{2}+3 \end{gathered}\)

So, now we have got:

- Multiplied the divisor by 2x² and then by -5x/2

- Got a remainder of -5x/2 + 3

Now, we repeat once more:

To get -5x/2, we multiply the divisor by -5/4:

\(-\frac{5}{4}(2x-1)=-\frac{5\cdot2x}{4}+\frac{5}{4}=-\frac{5x}{2}+\frac{5}{4}\)

And we substract from the remainder:

\(\begin{gathered} -\frac{5x}{2}+3 \\ -(-\frac{5x}{2}+\frac{5}{4}) \\ \\ -\frac{5x}{2}+\frac{5x}{2}+3-\frac{5}{4} \\ \frac{12-5}{4} \\ \frac{7}{4} \end{gathered}\)

So, we have done:

- Multiplied the divisor by 2x² then -5x/2 then -5/4

- Got a remainder of 7/4

This means that th result of the division is:

\(2x^2-\frac{5x}{2}-\frac{5}{4}\)

And the remainder is:

\(\frac{7}{4}\)

But, the answer wants us to write what the dividend is equal to.

Let's write first in the division form:

\(\frac{4x^3-7x^2+3}{2x-1}=2x^2-\frac{5x}{2}-\frac{5}{4}+\frac{\frac{7}{4}}{2x-1}\)

Notice that we result is the quotient plus the remainder divided by the divisor.

If we multiply both sides by the divisor, we will get:

\(4x^3-7x^2+3=(2x-1)\mleft(2x^2-\frac{5x}{2}-\frac{5}{4}\mright)+\frac{7}{4}\)

That is the answer.

Answers

well, from 1990 to 1998 is 8 years, and we know the amount went from $4800 to $6300, let's check for the rate of growth.

\(\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$6300\\ P=\textit{initial amount}\dotfill &\$4800\\ r=rate\to r\%\to \frac{r}{100}\\ t=\textit{years}\dotfill &8\\ \end{cases} \\\\\\ 6300=4800(1 + \frac{r}{100})^{8} \implies \cfrac{6300}{4800}=(1 + \frac{r}{100})^8\implies \cfrac{21}{16}=(1 + \frac{r}{100})^8\)

\(\sqrt[8]{\cfrac{21}{16}}=1 + \cfrac{r}{100}\implies \sqrt[8]{\cfrac{21}{16}}=\cfrac{100+r}{100} \\\\\\ 100\sqrt[8]{\cfrac{21}{16}}=100+r\implies 100\sqrt[8]{\cfrac{21}{16}}-100=r\implies \stackrel{\%}{3.46}\approx r\)

now, with an initial amount of $4800, up to 2007, namely 17 years later, how much will that be with a 3.46% rate?

\(\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &4800\\ r=rate\to 3.46\%\to \frac{3.46}{100}\dotfill &0.0346\\ t=years\dotfill &17\\ \end{cases} \\\\\\ A=4800(1 + 0.0346)^{17} \implies A=4800(1.0346)^{17}\implies A \approx 8558.02\)

A project under consideration has a 10-year projected life. The initial investment for the project is estimated to have a mean of $10,000 and a standard deviation of $1,000. The annual receipts are independent, with each year’s expected return having a mean of $1,800 and a standard deviation of $200. MARR is 12 percent. Assuming that initial investment and annual receipts are independent and normally distributed, estimate the probability that the present worth is negative using NORM.INV function in excel.

Answers

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

we can estimate the probability that the present worth is negative based on the given data and assumptions.

The height of a trapezoid is 4 in. And its area is 48 in 2. One base of a trapezoid is 6 inches longer than the other base. What are the lengths of the bases? Complete the explanation of how you found your answer.

Answers

Answer:

a=9

b=15

Step-by-step explanation:

Well the area formula of a trapezoid is: \(\frac{a+b}{2} *h\)

\(\frac{a+b}{2} *4=48\)

Divide both sides by 4

\(\frac{a+b}{2} =12\)

Multiply both sides by 2

a+b=24

Now since one of the sides (b) is 6 inches longer than a, we get;

a+a+6=24

Subtract 6 from both sides

2a=18

Divide both sides by 2

a=9

Answers

3)  since we don't have the information about the interest paid (I), we cannot determine the rate of interest at this time.

(1) To find the total amount Adrian paid in 36 months, we can multiply the monthly installment by the number of installments:

Total payment A = Monthly installment * Number of installments

              = $375 * 36

              = $13,500

Therefore, Adrian paid a total of $13,500 over the course of 36 months.

(2) In the simple interest formula I = Prt, the letters used represent the following variables:

I: Interest (the amount of interest paid)

P: Principal (the initial amount, or in this case, the car worth)

r: Rate of interest (expressed as a decimal)

t: Time (in years)

(3) To find the rate of interest in percentage, we need more information. The simple interest formula can be rearranged to solve for the rate of interest:
