The correct option is therefore;

C. 5

An arc of a circle is a part of the circumference of the circle

The measure of the specified arc is; (4·w - 5)°

The measure of the angle at the center of the circle is; (3·w)°

The measure of an arc of a circle is the same as the angle subtended at the center of the circle

Therefore, we get; (4·w - 5)° =  (3·w)°

(4·w - 5)° =  (3·w)°

4·w - 3·w = 5

w = 5

The value of w in the circle is 5.

An arc of a circle is a portion of the circumference of a circle. It is defined by two endpoints and the arc itself.

The measure of an arc is given in degrees or radians, and it is determined by the angle that it subtends at the center of the circle.

Thus, the measure of arc BC is (4w-5)° which is determined by (3w)°. That is:

(4w-5)° = (3w)°

4w-5 = 3w

4w - 3w = 5

w = 5

Therefore, the value of w is 5.

If the diameter of the reserve tank is 30.51 cm, the shortest height the reserve tank should be is 0 cm.

How to find?

The shortest height of the reserve tank can be determined using the formula for the volume of a cylinder.

The formula for the volume of a cylinder is \(V = π * r^2 * h\),

Where V is the volume, π is a constant approximately equal to 3.14159, r is the radius, and h is the height.

To find the shortest height, we need to find the maximum volume of the tank. Since the diameter is given as 30.51 cm, we can calculate the radius by dividing the diameter by 2.

radius = diameter / 2

= 30.51 cm / 2

= 15.255 cm

Substituting the values into the volume formula, we get:

\(V = π * (15.255 cm)^2 * h\)

To find the maximum volume, we need to maximize the height. Since we want the shortest height, we want to minimize the volume. Therefore, we set the volume equal to zero:

\(0 = π * (15.255 cm)^2 * h\)

Solving for h:

\(h = 0 / [π * (15.255 cm)^2]\)

h = 0 cm

Therefore, the shortest height the reserve tank should be is 0 cm.

The shortest height for the reserve tank is approximately 0.0184 cm (rounded to four decimal places).

To determine the shortest height of the reserve tank, we need to use the formula for the volume of a cylinder, which is V = \(\pi r^2h\), where V represents the volume, π is a constant approximately equal to 3.14159, r is the radius, and h is the height of the cylinder.
Given that the diameter of the reserve tank is 30.51 cm, we can calculate the radius by dividing the diameter by 2. Thus, the radius (r) is 30.51 cm / 2 = 15.255 cm.

To find the shortest height, we need to consider that the volume of the reserve tank should be non-zero. Therefore, we'll assume the minimum value for the height is 0.0001 cm.
Now, we can substitute the values into the formula and solve for the volume:
V = \(\pi r^2h\)
V = 3.14159 * (15.255 cm)^2 * 0.0001 cm
V ≈ 0.018411 \(cm^3\) (rounded to six decimal places)

The exponential function that determines the value of the car after x years is y = 18000(0.65)ˣ. Here the rate of decrease is the same each year.

The exponential function is the function that gives the relationship between the input and the output with a rate of increase or decreases exponentially. It is given by the formula,

y = abˣ

Where 'a' is the initial value, 't' is the time, and 'b' is the rate. If b > 1, then the function is said to be the exponential growth function, and if b < 1, the function is said to be the exponential decay function.

Given that, a car is sold for $18,000.

So, the initial value a = 18000.

After one year (x = 1), the value of the car is $11,700 i.e., y = 11700. So we can write the exponential function as

11700 = 18000(b)¹

⇒ b = 11700/18000 = 0.65

Since b < 1, the function is exponentially decaying.

Then, the value of the car after 'x' years is given by the exponential decay function as

y = 18000(0.65)ˣ

(It is given that, the rate of decrease is the same each year).

Answer:

Option A

Step-by-step explanation:

We will simplify the expressions given in the options first,

x² - 16 = (x - 4)(x + 4)

2x + 8 = 2(x + 4)

x² + 8x + 16 = (x + 4)²

Option A

\(\frac{x^2-16}{2x+8}\) × \(\frac{x+4}{x^2+8x+16}\)

= \(\frac{(x+4)(x-4)}{2(x+4)}\times \frac{(x+4)}{(x+4)^2}\)

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

Option B

\(\frac{2x+8}{x^2-16}\) ÷ \(\frac{x^2+8x+16}{x+4}\)

= \(\frac{2(x+4)}{(x+4)(x-4)}\) ÷ \(\frac{(x+4)^2}{(x+4)}\)

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

= \(\frac{2}{x^2-16}\)

Option C

\(\frac{x^2-16}{2x+8}\) ÷ \(\frac{x+4}{x^{2}+4x+16}\)

= \(\frac{(x-4)(x+4)}{2(x+4)}\times \frac{(x+4)^2}{(x+4)}\)

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

Option D

\(\frac{2x+8}{x^2-16}\times \frac{x^2+8x+16}{x+4}\)

= \(\frac{2(x+4)}{(x-4)(x+4)}\times \frac{(x+4)^2}{(x+4)}\)

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

Therefore, Option A is the answer.

Answer:

  a.  0

Step-by-step explanation:

You want the limit of (k(x) -h(x))/k(x) as x approaches 0 when k(x) = sin(x)/x {x≠0} and h(x)=x+1 {x<1}.

Since we're concerned about the limit as x → 0, we don't have to be concerned with the fact that the expression is undefined at x = 0.

The function h(x) is defined as h(0) = 1, so we can just be concerned with the value of ...

  lim[x→0] (k(x) -1)/k(x)

The limit of k(x) as x → 0 is 1, so this becomes ...

  lim[x→0] (k(x) -1)/k(x) = (1 -1)/1 = 0

At x=0, sin(x)/x is the indeterminate form 0/0, so its limit there can be found using L'Hôpital's rule. Differentiating numerator and denominator, we have ...

  lim[x→0] sin(x)/x = lim[x→0] cos(x)/1 = cos(0) = 1

The fact that k(0) = 0 is irrelevant with respect to this limit.

Additional comment

We like to use a graphing calculator to validate limit values. The attachment shows the various functions involved. It also shows that as x gets arbitrarily close to 0 from either direction, the value of g(x) does likewise. This is all that is required for (0, 0) to be declared the limit. The lack of definition of g(x) at x=0 simply means the relation has a (removable) discontinuity there.

15 feets ; 45 feets ; 60 feets ; 75 feets

Step-by-step explanation:

Given that:

Moving at a constant speed ; Distance traveled in 2 seconds = 30 feets

The traveling speed = distance / time

Traveling speed = 30 feets / 2 seconds

Traveling speed = 15 ft/s

Distance traveled = traveling speed * time

Distance traveled after 1 second :

Time = 1 second

15ft/s * 1s = 15 ft

Distance traveled after 3 second :

Time = 3 second

15ft/s * 3s = 45 ft

Distance traveled after 4 second :

Time = 4 second

15ft/s * 4s = 60 ft

Distance traveled after 5 second :

Time = 5 second

15ft/s * 5s = 75 ft

From the given information provided, the probability that X is more than or equal to 6.2 is approximately 0.79.

The probability that X is more than or equal to 6.2 can be found by calculating the area under the probability density function of X to the right of 6.2. Since X is a continuous uniform random variable, the probability density function is a straight line with a slope of (1/(11.3-5)) = 1/6.3, and a y-intercept of 1/(11.3-5) = 1/6.3.

The area under the probability density function of X to the right of 6.2 is given by:

∫[6.2,11.3] (1/6.3) dx

= (1/6.3) [x]_[6.2,11.3]

= (1/6.3) (11.3 - 6.2)

= 0.79365

Option (â): ˆ’[infinity], [infinity])` is the correct answer.

The given function is `f(x) = x - 3 - sqrt(3)`. To find the domain and range of this function, we can follow the steps mentioned below:

Domain of a function:

The domain of a function is the set of all possible values of x for which the function is defined or the input values of a function. A function is not defined if:

1. The denominator is zero.

2. We have a negative square root.

3. The logarithm of a negative number.

In the given function, we do not have any denominator or logarithm. We only have a square root, which is subtracted from `x-3`. Therefore, the function is defined for all real values of `x` greater than or equal to `3`. Hence, the domain of the function `f(x)` is `[3, [infinity])`.

Range of a function:

The range of a function is the set of all possible values of `y` that we get after putting different values of `x` in a function. In this case, we can see that the value of the square root is subtracted from `x-3`. Therefore, the minimum value of the function `f(x)` will be when the square root is maximum. The maximum value of the square root is `0`, which occurs when `x=3`. Hence, the minimum value of the function `f(x)` is `3-sqrt(3)`.

Similarly, the maximum value of the function will occur when the square root is `0` (i.e., when `x` approaches infinity). Hence, the maximum value of the function `f(x)` is `+infinity`.

Therefore, the range of the function `f(x)` is `(−[infinity], [infinity])`.

Hence, the correct option is `(−[infinity], [infinity])`. Therefore, option `(−[infinity], [infinity])` is the correct answer.

(b) 3 sinθ cosφ + 4 sinθ sinφ + 2 cosθ = 1/r, the equation in spherical coordinates.

(a) To write the equation \(2x^2 - 3x + 2y^2 + 2z^2 = 0\)in spherical coordinates, we need to express x, y, and z in terms of spherical coordinates. We have

x = r sinθ cosφ

y = r sinθ sinφ

z = r cosθ

Substituting these expressions into the given equation, we get

\(2(r sin\theta cos\phi)^2 - 3(r sin\theta cos\phi) + 2(r sin\theta sin\phi)^2 + 2(r cos\theta)^2 = 0\)

Simplifying, we get

\(2r^2(sin^2\theta cos^2\phi + sin^2\theta sin^2\phi) + 2r^2 cos^2\theta - 3r sin\theta cos\phi = 0\)

Using the identity \(sin^2\theta + cos^2\theta = 1\), we can simplify this equation further to get

\(2r^2 + (2r^2 - 3r) sin\theta cos\phi = 0\)

Dividing both sides by \(r^2\) and rearranging, we get

\(2 + (2 - 3/r) sin\theta cos\phi = 0\)

This is the equation in spherical coordinates.

(b) To write the equation 3x + 4y + 2z = 1 in spherical coordinates, we again need to express x, y, and z in terms of spherical coordinates. Substituting these expressions into the given equation, we get

3(r sinθ cosφ) + 4(r sinθ sinφ) + 2(r cosθ) = 1

Simplifying, we get

r(3 sinθ cosφ + 4 sinθ sinφ + 2 cosθ) = 1

The center of the circle is (0, 0) and the radius is 5.

The equation of the circle is x² + y² = 25.

By comparing this equation to the standard form of a circle,

(x - h)² + (y - k)² = r²,

we can identify the center and radius of the circle.

In this case, the equation x² + y² = 25 represents a circle centered at the origin (0, 0) because there are no constants added or subtracted from x² and y².

The radius of the circle is the square root of the constant term, which is √25 = 5.
