The length of the arc CD is 14.13 centimeters.
How to find the length of CD?Remember that for an arc defined by an angle a in a circle of radius R, the length of the arc is given by:
L = (a/360°)*2*pi*R
Where pi = 3.14
Here the angle is a = 45°
And R = 18cm, so we can replace that in the formula above to find the length.
L = (45°/360°)*2*3.14*18cm = 14.13cm

What is expression division?Expression division is a mathematical operation where one expression is divided by another. In mathematics, an expression is a combination of numbers, variables, and operators that represent a mathematical relationship or a value. Division is an arithmetic operation that involves splitting a quantity into equal parts or groups.
So, expression division refers to dividing one mathematical expression by another. For example, if we have two expressions "x + 5" and "3", we can perform expression division by dividing the first expression by the second expression, which would result in the expression "(x + 5) ÷ 3".

The lines below are perpendicular. If the slope of the green line is -1/6, what is the slope of the red line?
Answer:
slope of red line=6
Step-by-step explanation:
Hi there!
We're given a set of perpendicular lines and the slope of the green line being -1/6
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
So to find the slope of the red line, we can use this formula (m is the slope):
-1/6m=-1
Multiply both sides by -6 (clears the fraction to get 1m on the left)
m=6
So the slope of the red line is 6

prove that tan theta * sin theta = (1 - cos^2 theta)/(sqrt(1 - sin^2 theta))
Answer:
This identity holds as long as \(\displaystyle \theta \ne k\, \pi + \frac{\pi}{2}\) for all integer \(k\).
For the proof, make use of the fact that:
\(\displaystyle \tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}\) (definition of tangents,) and
\(\cos(\theta) = \sqrt{1 - \sin^{2}(\theta)}\) (Pythagorean identity,) which is equivalent to \(1 - \cos^{2}(\theta) = \sin^{2}(\theta)\).
Step-by-step explanation:
Assume that \(\displaystyle \theta \ne k\, \pi + \frac{\pi}{2}\) for all integer \(k\). This requirement ensures that the \(\tan(\theta)\) on the left-hand side takes a finite value. Doing so also ensures that the denominator \(\sqrt{1 - \sin^2(\theta)}\) on the right-hand side is non-zero.
Make use of the fact that \(\displaystyle \tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}\) to rewrite the left-hand side:
\(\begin{aligned} & \tan(\theta) \cdot \sin(\theta) \\ =&\; \frac{\sin({\theta})}{\cos({\theta})} \cdot \sin(\theta) \\ =&\; \frac{\sin^{2}(\theta)}{\cos(\theta)}\end{aligned}\).
Apply the Pythagorean identity \(\sin^{2}(\theta) = 1 - \cos^{2}(\theta)\) and \(\cos(\theta) = \sqrt{1 - \sin^{2}(\theta)}\) to rewrite this fraction:
\(\begin{aligned} & \frac{\sin^{2}(\theta)}{\cos(\theta)}\\ =\; &\frac{1 - \cos^{2}(\theta)}{\cos(\theta)}\\ =\; & \frac{1 - \cos^{2}(\theta)}{\sqrt{1 - \sin^{2}(\theta)}}\end{aligned}\).
Hence, \(\displaystyle \tan(\theta) \cdot \sin(\theta) = \frac{1 - \cos^{2}(\theta)}{\sqrt{1 - \sin^{2}(\theta)}}\).

Tell me why the total for everything can't be $1.70.
The Total cost for 24 cents (pencils) + 8N cents (notebooks) + 12P cents (colored paper) = 170 cents.
The total for everything cannot be $1.70, the individual costs and calculate the total cost separately.
the price of each notebook is N cents and the price of each sheet of colored paper is P cents.
The cost of the pencils can be calculated as follows:
For the 2 pencils at 2 cents each: 2 pencils * 2 cents/pencil = 4 cents
For the 5 pencils at 4 cents each: 5 pencils * 4 cents/pencil = 20 cents
So, the total cost of the pencils is 4 cents + 20 cents = 24 cents.
the cost of the notebooks and colored paper:
The cost of 8 notebooks is 8 notebooks * N cents/notebook = 8N cents.
The cost of 12 sheets of colored paper is 12 sheets * P cents/sheet = 12P cents.
the total cost of the notebooks and colored paper, we add these two amounts together: 8N cents + 12P cents.
the total cost for everything is $1.70, we can express it in cents as 170 cents.

-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)
y = (2)³ - 4(2) + 6 = 6: (2, 0)

The diameter of the washers are required to be between 1.53 millimeters and 1.65 millimeters long. Any washers that do not meet this requirement must be discarded. What percentage of washers will the factory have to discard
Answer:
32%
Step-by-step explanation:
Let x be the mean of the values and σ their standard deviation.
Since the minimum value of the diameter of the washers is 1.53 mm, then
x - σ = 1.53 mm (1)
Also, the maximum value of the diameter of the washers is 1.65 mm, then
x + σ = 1.65 mm (2)
Adding (1) and (2), we have
x - σ = 1.53 mm
+
x + σ = 1.65 mm
2x = 3.18
x = 3.18/2
x = 1.59 mm
Subtracting (1) and (2), we have
x - σ = 1.53 mm
-
x + σ = 1.65 mm
-2σ = -0.12
σ = -0.12/-2
σ = 0.06 mm
Since the diameter of the washers are required to be between 1.53 millimeters and 1.65 millimeters long, and x - σ = 1.53 mm to x + σ = 1.65 mm are the required values, 68% of the washers lie in this range. The other values lie outside this range. The amount that the factory would have to discard is 100% - 68% = 32%
This question is based on the percentage. Thus, 32% of washers will the factory have to discard.
Given:
The diameter of the washers are required to be between 1.53 millimeters and 1.65 millimeters long.
We need to determined the percentage of washers will the factory have to discard.
According to question,
Let x be the mean and σ be their standard deviation.
The minimum value of the diameter of the washers is 1.53 mm.
Then,
x - σ = 1.53 mm (1)
Also, the maximum value of the diameter of the washers is 1.65 mm, then
x + σ = 1.65 mm (2)
Adding (1) and (2), we have
x - σ = 1.53 mm
+ x + σ = 1.65 mm
⇒ 2x = 3.18
We get,
x = 1.59 mm
Subtracting (1) and (2), we have
x - σ = 1.53 mm
- x + σ = 1.65 mm
⇒ -2σ = -0.12
We get,
σ = 0.06 mm
Therefore, the diameter of the washers are required to be between 1.53 millimeters and 1.65 millimeters long, and x - σ = 1.53 mm to x + σ = 1.65 mm are the required values, 68% of the washers lie in this range.

h(0)=24
So the initial height of the rocket is 24 metres.
The rocket will hit the ground when its height is 0 metres, so we can set h = 0 in the equation and solve for t:
0 = -4t²+ 16t + 24
-4t² + 16t + 24 = 0
t=-0.88 seconds
So the rocket will hit the ground after approximately 0.88 seconds.
The height of the rocket after 4 seconds is given by:
h(4)== -4(4)²+ 16(4) + 24
=-64+64+24
=24
So the height of the rocket after 4 seconds is 24 metres.
Hence, the initial height of the rocket is 24 metres, the rocket hit the ground in 0.88 seconds and the height of the rocket after 4 seconds is 24 metres.
