solve for f
f/40 = 10/f
Answer:
Step-by-step explanation:
To solve for f, we can cross-multiply the equation:
f/40 = 10/f
Multiplying both sides by 40f gives:
f^2 = 400
Taking the square root of both sides yields:
f = ±20
Therefore, the solutions for f are f = 20 and f = -20. However, since f represents a physical quantity (presumably a frequency), we take only the positive value:
f = 20
Integral..Could you help me,please?
Answer:
as we know, the integral of \(x^{n}\) is \(\frac{x^{n+1} }{n+1}\)
so, the integral of x.\(2^{x}\) will be found as follows:
here, we will use a trick called 'integration by parts'
let x = u and \(2^{x}\) = v
∫uv dx = u∫v dx - ∫[(du/dx)* ∫v dx] dx
∫x.\(2^{x}\) dx = x∫\(2^{x}\) - ∫[(dx/dx) * ∫\(2^{x}\) dx ] dx
∫x.\(2^{x}\) dx = x*\(\frac{2^{x+ 1}}{x+ 1}\) - 1 * \(\frac{2^{x + 1} }{x + 1}\)
= \(\frac{2^{x} }{x + 1}\)( x - 1 )

what is the nat term of the sequence -3, 0, 5, 10, 25, 5, 47 ?
The nth term of the sequence -3, 0, 5, 10, 25, 5, 47 can be represented by the piecewise function:
nth term =
-3 + (n - 1) * 5, if n mod 5 ≤ 5
5 + (n - 1) * 15, if n mod 5 > 5
To find the nth term of a sequence, we need to identify the pattern or rule that governs the sequence. Upon analyzing the given sequence -3, 0, 5, 10, 25, 5, 47, we can observe the following:
The sequence starts with -3 and increases by 5 each time, except for the 5th term, where it increases by 15 (from 10 to 25). After the 5th term, the sequence starts again with 5 and continues to increase by 15 each time.
Based on this pattern, we can divide the sequence into two parts:
Part 1: -3, 0, 5, 10, 25 (increasing by 5 each time)
Part 2: 5, 20, 35, 50, 65 (increasing by 15 each time)
Now, to determine the nth term, we can consider the formula for arithmetic sequences:
nth term = first term + (n - 1) * common difference
For Part 1, the first term is -3 and the common difference is 5. Thus, the nth term for Part 1 is given by:
nth term = -3 + (n - 1) * 5
For Part 2, the first term is 5 and the common difference is 15. Therefore, the nth term for Part 2 can be expressed as:
nth term = 5 + (n - 1) * 15
However, since the sequence alternates between Part 1 and Part 2, we need to determine which part the nth term falls into. For that, we can use modular arithmetic:
If n mod 5 is less than or equal to 5, then the nth term is from Part 1.
If n mod 5 is greater than 5, then the nth term is from Part 2.
Let's calculate a few terms to illustrate this:
For n = 1, the sequence starts with -3, so the 1st term is -3.
For n = 2, we are still in Part 1, so the 2nd term is 0.
For n = 3, Part 1 continues, so the 3rd term is 5.
For n = 4, we are still in Part 1, so the 4th term is 10.
For n = 5, Part 1 ends, and the 5th term is 25.
For n = 6, the sequence starts with 5 in Part 2, so the 6th term is 5.
For n = 7, Part 2 continues, so the 7th term is 20.
For n = 8, we are still in Part 2, so the 8th term is 35.
Based on this analysis, we can conclude that the nth term for the given sequence is:
If n mod 5 ≤ 5:
nth term = -3 + (n - 1) * 5
If n mod 5 > 5:
nth term = 5 + (n - 1) * 15
Therefore, depending on the value of n and the remainder when divided by 5, we can use the appropriate formula to calculate the nth term.

You roll two fair dice, one green and one red. (a) Are the outcomes on the dice independent? Yes No (b) Find P(1 on green die and 5 on red die). (Enter your answer as a fraction.) (c) Find P(5 on green die and 1 on red die). (Enter your answer as a fraction.) (d) Find P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)). (Enter your answer as a fraction.)
Answer:
a
Yes
b
\(P(1 \& 5) = \frac{1}{36}\)
c
\(P(5 \& 1) = \frac{1}{36}\)
d
\(P(5 \& 1 | 1\& 5 ) = \frac{1}{18}\)
Step-by-step explanation:
From the question we are told that
Two fair dice, one green and one red were rolled
Generally the outcomes on the dice independent because the outcome on the first dice is not affected by the second die
Generally the probability of getting a 1 on a dice rolled is \(P(1) = \frac{1}{6}\)
the probability of getting a 5 on a dice rolled is \(P(5) = \frac{1}{6}\)
Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as
\(P(1 \& 5) = \frac{1}{6} *\frac{1}{6}\)
\(P(1 \& 5) = \frac{1}{36}\)
Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as
\(P(5 \& 1) = \frac{1}{6} *\frac{1}{6}\)
\(P(5 \& 1) = \frac{1}{36}\)
Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as
\(P(5 \& 1 | 1\& 5 ) = \frac{1}{36} + \frac{1}{36}\)
\(P(5 \& 1 | 1\& 5 ) = \frac{1}{18}\)

Points A and B are on opposite sides of a lake. Another point, C. is 94.4 meters from Angle A. The measure of Angle A is 72° and the measure of Angle C is 30°. Find the distance between A and B.
To find the distance between points A and B, we can use trigonometry and the given information.
Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.
Using trigonometry, we can use the tangent function to find the value of "d".
tan(72°) = d / 94.4
To solve for "d", we can rearrange the equation:
d = tan(72°) * 94.4
Using a calculator, we can evaluate the expression:
d ≈ 4.345 * 94.4
d ≈ 408.932
Therefore, the distance between points A and B is approximately 408.932 meters.

Complete the square to find
the vertex of this parabola.
x2 - 6x – y + 17 = 0
Answer:
(3, 8)
Step-by-step explanation:
x² - 6x - y + 17 = 0
x² - 6x = y - 17
x² - 6x + 9 = y - 17 + 9
(x - 3)² = y - 8
The vertex is (3, 8)
The vertex of the parabola given by the equation x² - 6x - y + 17 = 0 is (3, 8).
To complete the square and find the vertex of the parabola given by the equation x² - 6x - y + 17 = 0, we can follow these steps:
1. Rearrange the equation: Move the constant term (17) to the other side of the equation by subtracting it from both sides. This gives us x² - 6x - y = -17.
2. Group the x-terms together: Rearrange the equation so that the x-terms are next to each other. This gives us x² - 6x = y - 17.
3. Complete the square: Take half of the coefficient of x (-6) and square it. Add this value to both sides of the equation. Half of -6 is -3, and (-3)² is 9. So we add 9 to both sides: x² - 6x + 9 = y - 17 + 9.
4. Simplify the equation: On the left side, the expression x² - 6x + 9 can be factored as (x - 3)². On the right side, -17 + 9 simplifies to -8. So the equation becomes (x - 3)² = y - 8.
5. Rewrite the equation in vertex form: The vertex form of a parabola is (x - h)² = 4p(y - k), where (h, k) represents the vertex of the parabola. Comparing this with our equation, we have (x - 3)² = y - 8, which matches the vertex form.
6. Identify the vertex: By comparing the equations, we can see that the vertex of the parabola is at the point (h, k) = (3, 8).
Therefore, by completing the square, we have found that the vertex of the parabola given by the equation x² - 6x - y + 17 = 0 is (3, 8).

Which inequality is equivalent to the given inequality? -4(x+7)< 3(x-2)
An equivalent inequality to the given \(-4(x + 7) < 3(x - 2)\) is \(7x > -22.\)
To find an equivalent inequality, we can start by simplifying the given inequality and then make adjustments to preserve its truth.
Let's simplify the given inequality step by step:
\(-4(x + 7) < 3(x - 2)\)
Expanding both sides:
\(-4x - 28 < 3x - 6\)
Grouping like terms:
\(-4x - 3x < -6 + 28\)
Simplifying:
\(-7x < 22\)
To maintain the direction of the inequality, we need to multiply both sides by -1.
However, when we multiply or divide both sides of an inequality by a negative number, the direction of the inequality is reversed.
Therefore, we need to flip the inequality sign:

whats the equation of a line that passes through point (-1,3) with slope of 1
The equation of the line that passes through the point (-1, 3) with a slope of 1 is y = x + 4.
To find the equation of a line that passes through the point (-1, 3) with a slope of 1, we can use the point-slope form of a linear equation.
The point-slope form of a linear equation is given by:
y - y1 = m(x - x1)
where (x1, y1) represents the coordinates of a point on the line, and m represents the slope of the line.
Using the given point (-1, 3) and slope 1, we substitute these values into the point-slope form equation:
y - 3 = 1(x - (-1))
Simplifying:
y - 3 = x + 1
Now, we can rewrite the equation in the standard form:

Central angle ∠C and circumscribed angle ∠S intersect the same arc, so the angles are supplementary. Central angle ∠C and inscribed angle ∠R intersect the same arc, so m∠R is half the measure of central angle ∠C.
What makes the angles supplementary?Central angles are angles that have their vertex at the center of the circle. Circumscribed angles are angles that are formed by two tangents to a circle that intersect at a point outside the circle. Inscribed angles are angles that are formed by two chords in a circle that intersect at a point inside the circle.
The measures of central angles and circumscribed angles are always supplementary, which means that their measures add up to 180 degrees. Inscribed angles, on the other hand, are always half the measure of the central angle that intersects the same arc.
In the diagram, central angle ∠C and circumscribed angle ∠S intersect the same arc, so they are supplementary. Central angle ∠C and inscribed angle ∠R also intersect the same arc, so m∠R is half the measure of central angle ∠C.
