Answer:

  an = 7 -3(n -1)

Step-by-step explanation:

You want the formula for the n-th term of the arithmetic sequence 7, 4, 1, -2, ....

An arithmetic sequence has a first term (a1) and a common difference (d) found by subtracting the previous term from the current term.

In the given sequence, the first term is a1=7, and the common difference is d=(a2 -a1) = 4 -7 = -3.

The n-th term of the given arithmetic sequence is ...

  [tex]a_n=a_1+d(n-1)\\\\\boxed{a_n=7-3(n-1)}[/tex]

if x=0than 3×0×(6×0)_< 9

An equation of the line that passes the through point (0, 9) and has slope m = [tex]\frac{2}{3}[/tex] is 3y-2x-27=0

What is point-slop equation of a line?

The point-slope equation of a line is

                      y - [tex]y_{1}[/tex] = m ( x  -[tex]x_{1}[/tex] )

The equation is useful when we know:

and want to find other points on the line.

Given that,

slope , m =  [tex]\frac{2}{3}[/tex]  and passing through the point is (0,9)

An equation of a line given the slope and a point is

             y - [tex]y_{1}[/tex] = m ( x  -[tex]x_{1}[/tex] )

or          y - 9 =  [tex]\frac{2}{3}[/tex] (x - 0)

or          y - 9 =  [tex]\frac{2}{3}[/tex] x

or          y =  [tex]\frac{2}{3}[/tex] x + 9

or          y = [tex]\frac{2x + 27}{3}[/tex]

or          3y = 2x + 27

or         3y - 2x - 27 = 0

Hence, an equation of the line that passes the through point (0, 9) and has slope m = [tex]\frac{2}{3}[/tex] is 3y-2x-27=0

Answer:

Step-by-step explanation:

You want to find the rational function (f/g)(x) and its value for x=1 when f(x) = 4x^4−19x^3−10x^2+35x−50 and g(x) = x-5.

The ratio function is the ratio of the given functions, found by dividing f(x) by g(x). Since g(x) is a binomial with a leading coefficient of 1, synthetic division is recommended. The attachment shows the result.

  [tex](f/g)(x)=\dfrac{f(x)}{g(x)}=\dfrac{4x^4-19x^3-10x^2+35x-50}{x-5}\\\\\boxed{(f/g)(x)=4x^3+x^2-5x+10}[/tex]

The value of this function when x=1 is ...

  (f/g)(1) = 4·1³ +1² -5·1 +10 = 4 +1 -5 +10

  (f/g)(1) = 10

Answer:  [tex]-4 < m \le -3[/tex]

=========================================================

Reason:

If m = -4, then f(x) = m becomes f(x) = -4. This yields the single solution x = -4

How do we get this solution? Start at -4 on the y axis. Move horizontally until reaching the curve. You should arrive at (-4,-4) which is the lowest point of this curve. Then move upward until reaching the x axis to arrive at x = -4

All of this says that the input x = -4 leads to the output y = f(x) = -4

---------------

We've gone over m = -4 leading to one solution, so that's out of the question since we want two solutions.

But if m = -3 for instance, then notice how tracing a horizontal line to the curve arrives at two locations instead of one. We arrive at x = -2 and x = -5 as the solutions to f(x) = -3

All of these solutions mentioned are negative which fits the criteria we're after. If m is in the interval from -4 to -3, excluding -4 but including -3, then we'll have f(x) = m with two negative solutions for x.

By using trigonometric formulas and integration rules, we conclude that the integral is approximately equal to - 7.764 units.

In this problem we must determine the solution to a definite integral of trigonometric equations, which requires the use of trigonometric formula and integration rules to be found. The integral can be simplified by using the following formulas:

sin⁴ x = (1 / 8) · (3 - 4 · cos 2x + cos 4x)

sin² x = (1 /2) · (1 - cos 2x)

Then, the integral is simplified into this form:

[tex]I = \pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{4} x \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{2} x \,dx[/tex]

[tex]I = \frac{\pi}{8} \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (3 - 4\cdot \cos 2x + \cos 4x) \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (1 - \cos 2x) \,dx[/tex]

[tex]I = \frac{3\pi}{8}\cdot x - \frac{\pi}{4} \cdot \sin 2x + \frac {\pi}{32}\cdot \sin 4x - 4\pi \cdot x - 2\pi\cdot \sin 2x[/tex], for x ∈ [π / 6, 3π / 4]

And the definite integral is:

I = 2.159 + 1.466 - 0.085 - 23.028 + 11.724

I = - 7.764

The definite integral of f(x) = sin⁴ x + 4 · sin² x for x ∈ [π / 6, 3π / 4] is approximately equal to - 7.764.

Given:

The equation of the graph is x + y = 500.

The objective is to change the equation as inequality and to choose the correct region for shading.

Explanation:

As the equation is given as x + y = 500, the sum of the values of x and y lies within the 500. As its total sum is also equal to 500, the graph must lie with in the maximum range of 500 that is at A along with solid line. (If sum is not equal to 500, the graph will contain dotted line).

Representation of inequality:

The given equation can be represented in the form of inequality as,

f(x) = 50^x

f(x) = 100^x

f(x) = 2(25)^x

f(x) = 4(25)^x

The equivalent function too expression is f(x)= 2(25)ˣ. Thus option c is correct.

The expression of function f(x) given, f(x)=2(5)²ˣ.

Thinking and cognition are related to reasoning, which requires using one's intellect. The study of logic focuses on how people can construct logically sound arguments using formal reasoning. Deductive, inductive, and abductive reasoning are three examples of logical reasoning that can be used to further break down reasoning. Aristotle distinguished between logical discursive reasoning (reason proper) and intuitive reasoning, noting that the former may lean toward the subjective and the personal, despite being correct. While logical and intuitive styles of reasoning might clash in certain social and political circumstances, in others they are considered as complimentary rather than competitive.

1. The scenario represents a payout annuity.

2. Marcy can withdraw $1,833.60 per quarter until after 3 years when the inheritance will be exhausted.

A periodic withdrawal is the opposite of a periodic payment.

In a periodic withdrawal, the investor withdraws a constant amount from the investment that earns interest until it is exhausted.

A periodic withdrawal is the same as a payout annuity, which involves periodic receipts from the invested capital.

Using an online finance calculator, we can compute the quarterly withdrawals as follows:

N (# of periods) = 12 quarters (3 x 4)

I/Y (Interest per year) = 6%

PV (Present Value) = $20,000

FV (Future Value) = $0

Results:

Withdrawals = $-1,833.60

Sum of all periodic payments = $-22,003.20

Total Interest $2,003.20

Thus, in this payout annuity, Marcy can withdraw $1,833.60 quarterly for 3 years.
