The critical point is x = -1/2, the function has a local minimum at x = 1 and an absolute maximum at x = 4, and the absolute minimum is at x = -1/2.

a. The critical point is x = -1/2.

To find the critical point(s), we need to find where the derivative of the function is equal to zero or undefined. In this case, we have:

f(x) = -4x - x^2 + 2

f'(x) = -4 - 2x

Setting f'(x) equal to zero, we get:

-4 - 2x = 0

-2x = 4

x = -2/2

x = -1

However, we need to check if this value is in the given interval (1-4, 4). Since -1 is not in the interval, it is not a critical point.

Next, we check the endpoints of the interval.

When x = 1, f(x) = -4 - 1^2 + 2 = -3.

When x = 4, f(x) = -4 - 4^2 + 2 = -22.

So the function has a local minimum at x = 1, and an absolute maximum at x = 4, and no local maximum.

b. The local maximum is at x = 4, and the local minimum is at x = 1.

We can use the First Derivative Test to locate the local maximum and minimum points. If the derivative changes sign from positive to negative at a point, then it is a local maximum. If the derivative changes sign from negative to positive at a point, then it is a local minimum.

In this case, we have f'(x) = -4 - 2x. It is negative for x < -2 and positive for x > -2. Therefore, the function is decreasing for x < -2 and increasing for x > -2. Since the interval is (1-4, 4), the critical points are -2 and 4.

For x = 4, we have f'(4) = -4 - 2(4) = -12, which is negative, so x = 4 is a local maximum.

For x = 1, we have f'(1) = -4 - 2(1) = -6, which is negative, so x = 1 is a local minimum.

Therefore, the local maximum is at x = 4, and the local minimum is at x = 1.

c. The absolute maximum is at x = 4, and the absolute minimum is at x = -1/2.

To find the absolute maximum and minimum, we need to evaluate the function at the critical points and endpoints of the interval, and choose the largest and smallest values, respectively.

We have already found that the local maximum is at x = 4, and the local minimum is at x = 1. We also found that x = -1/2 is a critical point, but it is not in the given interval, so we can ignore it.

Evaluating the function at the endpoints of the interval, we get:

f(1) = -3

f(4) = -22

Therefore, the absolute maximum is at x = 4, and the absolute minimum is at x = 1/2.

The absolute maximum value of the function on the interval (-5, 11) is 670, which occurs at x = -5, and the absolute minimum value is approximately 400.847, which occurs at x ≈ 1.154.

To find the absolute maximum and minimum values of the function f(x) = -2x^3 + 8x + 400 on the interval (-5, 11), we need to consider the critical points and the endpoints of the interval.

First, we find the derivative of the function:

f'(x) = -6x^2 + 8

Setting f'(x) = 0 to find the critical points, we get:

-6x^2 + 8 = 0

x^2 = 4/3

x = ±√(4/3)

Since only √(4/3) is within the interval (-5, 11), this is the only critical point we need to consider.

Next, we evaluate the function at the endpoints of the interval:

f(-5) = -2(-5)^3 + 8(-5) + 400 = 670

f(11) = -2(11)^3 + 8(11) + 400 = -1666

Finally, we evaluate the function at the critical point:

f(√(4/3)) = -2(√(4/3))^3 + 8(√(4/3)) + 400 ≈ 400.847

Therefore, the absolute maximum value of the function on the interval (-5, 11) is 670, which occurs at x = -5, and the absolute minimum value is approximately 400.847, which occurs at x ≈ 1.154.

Answer:

Step-by-step explanation:

You want the measures of the angles where lines cross if the sum of three of them is 280°.

Angle b and c form a linear pair, so ...

  b + c = 180°

Substituting that into the given equation, we have ...

  b + c + d = 280°

  180° + d = 280°

  d = 100°

Angles in this figure that do not share a side are vertical angles, hence congruent.

  b = d = 100°

  c = 180° -b = 180° -100° = 80° . . . . using the linear pair relation

  a = c = 80°

The downhill side of the crane base should be raised by approximately 4.53 inches to level the crane on a 2.5° slope.

We can use trigonometry here. Let x be the length (in inches) that the downhill side of the base should be raised. The slope of the ground is given to be 2.5°,

tan(2.5°) ≈ 0.0436

Now, using the equation,

x / 12 = 9tan(2.5°)

Here, we converted the base's width from feet to inches (by dividing by 12) and calculated the crane's required vertical displacement (inches) using the angle's tangent. When we simplify this equation, we obtain,

x = 9tan(2.5°)12

x ≈ 4.53 inches

Therefore, the downhill side of the base should be raised by about 4.53 inches to level the crane.

The approximate volume of the cylinder with a diameter of 14cm and height of 49cm is 10780.78 cubic centimeters, calculated using the formula V=πr²h.

To calculate the volume of a cylinder, we use the formula

Volume = πr²h

where π is pi, r is the radius of the cylinder, h is the height of the cylinder.

We are given the diameter of the cylinder, which is 14 cm. The radius of the cylinder is half of the diameter, so

radius = diameter / 2 = 14 cm / 2 = 7 cm

The height of the cylinder is given as 49 cm.

The value of x in the equation is -32.8.

To solve for X in the equation X - (-1.8) = -31, we need to follow some basic algebraic steps.

The first step is to simplify the equation by adding the two negatives, which would result in X + 1.8 = -31. The next step would be to isolate X by subtracting 1.8 from both sides of the equation.

This will give us X = -32.8.
The value of X in this equation is -32.8.
It's essential to keep in mind the basic rules of algebra when solving such equations.

By following the rules and taking it step by step, we can solve any equation, regardless of how complex it may seem.
In conclusion,

X - (-1.8) = -31 is a straight forward equation that can be solved using basic algebraic steps.

The value of X is -32.8.
The given equation is X - (-1.8) = -31.
When you see a subtraction of a negative number, you can rewrite it as addition of the positive number. So, X - (-1.8) becomes X + 1.8. The equation now is:
X + 1.8 = -31
To find the value of X, subtract 1.8 from both sides of the equation:
X + 1.8 - 1.8 = -31 - 1.8

We can simplify by adding the values of the two negative numbers on the left side of the equation:

X + 1.8 = -31

Next, we can isolate the variable x by subtracting 1.8 from both sides of the equation:

X = -31 - 1.8

Simplifying further, we get:

X = -32.8
This simplifies to: X = -32.8
So, the value of X is -32.8 in the equation X - (-1.8) = -31.

That is, the points on the graph where the curve crosses the X-axis.

From the graph, we note that the curve of the function crosses the X-axis at the points x = 1 and x = -5.

Alternating Series Test states that if a series satisfies three conditions, namely the terms alternate in sign, the absolute value of the terms decreases as n increases, and the limit of the terms approaches zero as n approaches infinity, then the series converges.

The given series (-1)^n satisfies the first two conditions as the terms alternate in sign and the absolute value of the terms is decreasing. To check the third condition, we take the limit of the terms as n approaches infinity: lim n→∞ |(-1)^n+1/n+1| = lim n→∞ 1/(n+1) = 0.

Since all three conditions are satisfied, the series converges. We can also see from the given partial sums that the sum s lies between 83 and 85. Therefore, s - 85 is negative or zero.

For this quadratic equation, the discriminant Δ is given by:

3. Critically damped: If Δ = 0, the solution will be critically damped.

Now, we find the intervals of b for each case:

1. Overdamped (Δ > 0):
b^2 - 24 > 0
This inequality holds for b ∈ (-∞, -2√6) ∪ (2√6, ∞).

To calculate the length of the strip of plastic needed, we first need to determine the circumference of the tire. The formula for the circumference of a circle is C=2πr, where C is the circumference, π is approximately 3.14, and r is the radius of the circle.

In this case, the tire diameter is 26 inches, so the radius is 13 inches (half of the diameter). Therefore, the circumference of the tire is: C = 2πr = 2π(13)     = 81.64 inches (rounded to two decimal places)

To ensure that the strip of plastic fits snugly between the tube and tire, it should be the same length as the circumference of the tire. Therefore, the strip of plastic should be 82 inches long (rounded to the nearest inch).

In summary, the bicycle mechanic should cut a strip of plastic that is 82 inches long to fit between the tube and tire of the 26-inch diameter bicycle tire.
