Step-by-step explanation:
The zeroes of f(x) are -2, -3 and 2.
Hence f(x) = (x + 2)(x + 3)(x - 2) = (x + 3)(x² - 4) = x³ + 3x² - 4x - 12.
The sum of the sequance 3,7,15,31....for the first 110 terms
The sum of the first 110 terms of the given sequence is given by the expression \(3(1 - 2^110) / (1 - 2)\).
The given sequence appears to follow a pattern where each term is obtained by multiplying the previous term by 2 and adding 1. We can observe this pattern as follows:
3, 7, 15, 31, ...
To find the sum of the first 110 terms of this sequence, we need to calculate the sum of each term from the first term (3) to the 110th term.
To do this, we can use the formula for the sum of a geometric series:
S = \(a(1 - r^n) / (1 - r)\),
where S is the sum, a is the first term, r is the common ratio, and n is the number of terms.
In this case, the first term a = 3,
the common ratio r = 2, and the number of terms n = 110.
Substituting these values into the formula, we get:
S =\(3(1 - 2^110) / (1 - 2)\).
Now, calculating this expression may be computationally intensive, but the formula allows us to find the sum of the first 110 terms of the given sequence.
In summary, the sum of the first 110 terms of the given sequence is given by the expression \(3(1 - 2^110) / (1 - 2)\).

A pulley is on the edge of a dock, 10 feet above the water level. A rope is being used to pull in a boat. The rope is attached to the boat at water level. The rope is being pulled in at the rate of 3 feet per second. Find the rate at which the boat is approaching the dock at the instant the boat is 2 feet from the dock.
The boat is approaching the dock is 3 feet per second at the instant the boat is 2 feet from the dock.
Given that a pulley is on the edge of a dock, 10 feet above the water level.
A rope is being used to pull in a boat. The rope is attached to the boat at water level. The rope is being pulled in at the rate of 3 feet per second.
We need to find the rate at which the boat is approaching the dock at the instant the boat is 2 feet from the dock.
Let the distance between the boat and the dock be y and the length of the rope be x.
Therefore, y + 10 = x
Now, we have to find the rate at which the boat is approaching the dock at the instant the boat is 2 feet from the dock. We need to differentiate the above equation with respect to time.
We have the rate of change of the distance between the boat and the dock with respect to time.
Therefore, we get d(x) / d(t) = d(y + 10) / d(t)
Or, \(dx/dt = dy/dt\) ---------(1)
Now differentiate y + 10 = x with respect to time to get the value of dy/dt
We get \(dy/dt + 0 = dx/dt\)
Or, \(dy/dt = dx/dt\)------------- (2)
Substitute equation (2) in equation (1), we get
\(dx/dt = dy/dt = 3\) feet per second.
This means that the rate at which the boat is approaching the dock is 3 feet per second at the instant the boat is 2 feet from the dock.

Let f(x) = tan x, Show that f(0) = f(π) but there is no number c in (0, π) such that f’(c) = 0. Why does this not contradict Rolle’s Theorem?
This situation does not contradict Rolle's Theorem because Rolle's Theorem requires the function to be continuous on a closed interval and differentiable on an open interval, which is not satisfied by f(x) = tan x in the interval (0, π).
To show that f(0) = f(π), we evaluate the tangent function at these points. At x = 0, tan(0) = 0, and at x = π, tan(π) = 0. Therefore, f(0) = f(π).
To investigate whether there exists a number c in the interval (0, π) such that f'(c) = 0, we need to find the derivative of f(x). The derivative of tan x is given by f'(x) = sec² x. However, the secant squared function is never equal to zero. Therefore, there is no c in the interval (0, π) where f'(c) = 0.
This situation does not contradict Rolle's Theorem because Rolle's Theorem requires certain conditions to be met. First, the function must be continuous on the closed interval [a, b], which is not satisfied by f(x) = tan x since it is not defined at x = π/2. Second, the function must be differentiable on the open interval (a, b), but f'(x) = sec^2 x is not defined at x = π/2. Thus, the requirements of Rolle's Theorem are not fulfilled, and its conclusion does not apply to f(x) = tan x in the interval (0, π).

The sum of the series:
1 - 2/3 + 4/9 - 8/27+16/81 - 32/243 + .... = 2/3
All geometric sequences have a starting term a and a common ratio r.
The common ratio r is the number that the terms of the sequence are multiplied to find the next term, hence the name "ratio". All terms in the sequence are the same, hence the name "common".
The common ratios here are the numbers multiplied by 2/3 to get −4/9
and the numbers multiplied by−4/9 to get 8/27.
2/3⋅ 2/3 = \(\frac{2*2}{3*3 }\) = 4/9 .
2/3 × (-2/3) = -4/9
The infinite sum of the geometric series can only be found in a specific case: r lies between −1 and 1.
When r is between these values, adding the series will converge - close on both sides - to a certain number.
Otherwise the sum diverges - further apart - i.e. there is no specific value that the series approaches. is in This means that an infinite series can be computed as the number to which the series converges.

when the base-$b$ number $11011 b$ is multiplied by $b-1$, then $1001 b$ is added, what is the result (written in base $b$)?
we express the result in base $b$: $b^5 - 2b^4 + 3b^3 - 2b^2 + 2b^1 + b^0$ (written in base $b$)
To find the result when the base-$b$ number $11011_b$ is multiplied by $b-1$ and then $1001_b$ is added, we can follow these steps:
Step 1: Multiply $11011_b$ by $b-1$.
Step 2: Add $1001_b$ to the result from step 1.
Step 3: Express the final result in base $b$.
To perform the multiplication, we can expand $11011_b$ as $1 \cdot b^4 + 1 \cdot b^3 + 0 \cdot b^2 + 1 \cdot b^1 + 1 \cdot b^0$.
Now, we can distribute $b-1$ to each term:
$(1 \cdot b^4 + 1 \cdot b^3 + 0 \cdot b^2 + 1 \cdot b^1 + 1 \cdot b^0) \cdot (b-1)$
Expanding this expression, we get:
$(b^4 - b^3 + b^2 - b^1 + b^0) \cdot (b-1)$
Simplifying further, we get:
$b^5 - b^4 + b^3 - b^2 + b^1 - b^4 + b^3 - b^2 + b^1 - b^0$
Combining like terms, we have:
$b^5 - 2b^4 + 2b^3 - 2b^2 + 2b^1 - b^0$
Now, we can add $1001_b$ to this result:
$(b^5 - 2b^4 + 2b^3 - 2b^2 + 2b^1 - b^0) + (1 \cdot b^3 + 0 \cdot b^2 + 0 \cdot b^1 + 1 \cdot b^0)$
Simplifying further, we get:
$b^5 - 2b^4 + 3b^3 - 2b^2 + 2b^1 + b^0$

two complementary angles have a difference of 36°. Find the measure of each angle. (Complementary angles are angles that add up to 90°) Show ur work
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:
\(a+b=90\)
And we are told their difference is 36. Therefore:
\(a-b=36\)
Solve for the system of equations. Add b to both sides in the second equation:
\(a=b+36\)
Substitute this into the first:
\((b+36)+b=90\)
Combine like terms;
\(2b+36=90\)
Subtract 36:
\(2b=54\)
Divide by 2:
\(b=27\)
So, b is 27 degrees.
Use the second equation again:
\(a-b=36\)
Now that we know b is 27, substitute:
\(a-27=36\)
Add 27 to both sides:
\(a=63\)
So, a is 63 degrees.
And we're done :)
Answer:
27 and 63
Step-by-step explanation:
x - y = 36
x + y = 90
add the equations together
2x = 126
x = 63
substitute x for x in the first equation
63 - y = 36
y = 27

with slope –1/4, passing through (-4, -1)
Answer:
\(y = -\frac{1}{4}x - 2\)
Step-by-step explanation:
i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.
slope intercept form is \(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept. since the slope is already identified, you can plug in \(-\frac{1}{4}\) for \(m\).
\(y = mx + b\) ⇒ \(y = -\frac{1}{4}x+b\)plug in the \(x\) and \(y\) values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either \(x\) or \(y\), but i'm going to start with \(x\).
first, plug in \(-4\) for \(x\).
\(y = -\frac{1}{4}x+b\) ⇒ \(y = -\frac{1}{4}(-4)+b\)now plug in \(-1\) for \(y\).
\(y = -\frac{1}{4}(-4)+b\) ⇒ \(-1 = -\frac{1}{4}(-4)+b\)after plugging in all of the given values, the equation is now \(-1 = -\frac{1}{4}(-4)+b\), in which you need to solve for \(b\).
now it's time to solve! begin by multiplying \(-\frac{1}{4}(-4)\) in order to simplify the right side of the equation.
\(-\frac{1}{4}(-4) = 1\)you now have \(-1 = 1 + b\). subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with \(b\). on the left side of the equation, you now have \(-1 - 1\), which equals \(-2\).
therefore \(-2 = b\), or \(b = -2\).
now that you've solved for your \(b\) value, plug it into your initial slope-intercept form equation!
\(y = -\frac{1}{4}x + b\) ⇒ \(y = -\frac{1}{4}x - 2\)if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in \(-4\) for \(x\) and \(-1\) for \(y\).
\(y = -\frac{1}{4}x - 2\) ⇒ \(-1 = -\frac{1}{4}(-4) - 2\)begin simplifying by multiplying \(-\frac{1}{4}(-4)\).
\(-1 = -\frac{1}{4}(-4) - 2\) ⇒ \(-1 = 1 - 2\)subtract \(1 - 2\).
\(-1 = 1 - 2\) ⇒ \(-1 = -1\)since both sides of the equation are equal, that means your \(b\) value of \(-2\) is correct because it makes the equation true!

(a) Product of disjoint cycles is α = (1 3 4 5 2)(6)(7 8), (b) Product of transpositions is β = (1 2 7 3)(4 8 6 5) is even, (c) αβ = (1 4 5)(2 7 3)(6)(8) and the reverse order of the transpositions is β^(-1) = (3 7 2 1)(5 6 8 4).
(a) To express α as a product of disjoint cycles, we observe the cycles by tracing the numbers in α. Starting with 1, we see that α(1) = 3, α(3) = 4, α(4) = 5, α(5) = 2, α(2) = 1, α(6) = 6, α(7) = 8, and α(8) = 7. From this, we can write α as a product of disjoint cycles: α = (1 3 4 5 2)(6)(7 8).
(b) To express β as a product of transpositions, we consider the pairs of numbers that are swapped by β. We have β(1) = 2, β(2) = 7, β(7) = 3, β(3) = 1, β(4) = 8, β(8) = 6, β(6) = 5, and β(5) = 4. Thus, we can write β as a product of transpositions: β = (1 2 7 3)(4 8 6 5).
To determine whether β is even or odd, we count the number of transpositions. In β, we have four transpositions, so β is even.
(c) To compute αβ, we perform the composition of the two permutations. We substitute the values of β into α, starting with 1: α(β(1)) = α(2) = 1. Continuing this process, we find αβ = (1 4 5)(2 7 3)(6)(8).
To find β^(-1), we reverse the order of the transpositions: β^(-1) = (3 7 2 1)(5 6 8 4).

Step-by-step explanation:
hooke's law describes an ideal spring. many real springs are better described by the restoring force (fsp)s=−kδs−q(δs)3, where q is a constant. consider a spring with k = 150 n/m and q = 800 n/m3
Hooke's Law describes the behavior of an ideal spring, but many real springs are better represented by the restoring force equation F_s = -kδs - q(δs)^3, where q is a constant. In this case, we have a spring with k = 150 N/m and q = 800 N/m^3.
Hooke's Law states that the restoring force exerted by an ideal spring is directly proportional to the displacement from its equilibrium position. However, real springs may exhibit additional nonlinear behavior that is not captured by Hooke's Law. The restoring force equation given, F_s = -kδs - q(δs)^3, takes into account this nonlinear behavior with an additional term.
In the equation, δs represents the displacement from the equilibrium position of the spring, k is the spring constant that determines the strength of the linear restoring force, and q is a constant that accounts for the nonlinear behavior of the spring. For the specific spring in question, with k = 150 N/m and q = 800 N/m^3, the restoring force is given by F_s = -150δs - 800(δs)^3. The negative sign indicates that the force is in the opposite direction of the displacement.
The term -kδs represents the linear restoring force that follows Hooke's Law, while the term -q(δs)^3 accounts for the additional nonlinear behavior. The magnitude of the nonlinear force increases with the cube of the displacement, leading to a more pronounced deviation from ideal spring behavior for larger displacements. Understanding the behavior of real springs is important in various fields such as engineering, physics, and material science, where accurate modeling of spring systems is required for designing and analyzing mechanical systems. The inclusion of the q term in the restoring force equation allows for a more comprehensive description of the behavior of real springs.

When Richard rented a car, he paid $34.95 per day plus 18 cents per mile. If he rented the car for 2 days and drove 300 miles, how much did he pay?
According to the given information we can conclude that Richard paid $123.90 for the car rental.
To solve this problem, we need to calculate the total cost of the car rental based on the daily rate and the mileage charge.
First, we can calculate the cost of the rental for two days by multiplying the daily rate by the number of days:
2 days x $34.95 per day = $69.90
Next, we need to calculate the cost of the mileage charge. To do this, we can multiply the number of miles driven by the mileage rate:
300 miles x $0.18 per mile = $54.00
Finally, we can find the total cost of the car rental by adding the cost of the rental and the cost of the mileage charge:
$69.90 + $54.00 = $123.90
Therefore, Richard paid $123.90 for the car rental.
