URGENT! Write an expression that represents the volume of the nth chamber. Explain your reasoning.
Answers
The volume of the chamber follows a pattern. The formula that represents the volume of the nth chamber is 6.3% of the previous chamber.
What is a pattern?
A pattern is a repeated arrangement of numbers, shapes, colours, or other elements. The Pattern can be associated with any kind of event or object. A pattern is defined as a set of numbers that are related to one another in a specific way. Patterns are sometimes referred to as sequences.
Given that:
Chamber 7: 1.207 cm³
Chamber 6: 1.135 cm³
Chamber 5: 1.068 cm³
Chamber 4: 1.005 cm³
Chamber 3: 0.945 cm³
Chamber 2: 0.889 cm³
Chamber 2: 0.836 cm³
1.207 1.135 1.068 1.005 0.945 0.889 0.836
First difference: .072 0.067 0.063 0.060 0.056 0.053
Second difference: 0.005 0.004 0.003 0.004 0.003
Since the difference is not the same, thus the volume is not in a linear pattern. Then find the ratio consecutive volume:
1.207/1.135 ≈ 1.063
1.135/1.068 ≈ 1.063
1.068/1.005 ≈ 1.063
1.005/0.945 ≈ 1.063
0.945/0.889 ≈ 1.063
0.889/0.836 ≈ 1.063
Each chamber is 6.3% greater than the previous chamber. The pattern is exponential functions.

Find a linear differential operator that annihilates the given function. (Use D for the differential operator.) 4 ex cos 3x
Answers
If the function is
[tex]y = 4 e^x \cos(3x)[/tex]
then we have derivatives
[tex]Dy = 4 e^x \cos(3x) - 12 e^x \sin(3x)[/tex]
[tex]D^2y = -32 e^x \cos(3x) - 24 e^x \sin(3x)[/tex]
Now consider the linear ODE

Substituting [tex]y[/tex] and its derivatives reduces the equation to
[tex](-32a + 4b + 4c) \cos(3x) + (-24a - 12b) \sin(3x) = 0[/tex]
Now,

There are 400 beads in a box. 20% of them are red, 35% of them are yellow and the rest are green. How many green beads are there in the box
Answers
Step-by-step explanation:
400 is the whole = 100%
20% (= 20 out of 100 equal parts of 100%) are red.
how many are that ?
well, again, 400 = 100%
1% = 100%/100 = 400/100 = 4
20% = 20×1% = 20×4 = 80
when you combine these 2 steps, you see you get 20% by multiplying the 100% by 20/100 or 0.20.
400 × 0.2 = 80
now,
35% are yellow.
35% = 35×1% = 35×4 = 140
or
400×0.35 = 140
red + yellow = 80 + 140 = 220
the rest are green
400 - 220 = 180
we would get this also by seeing that
red + yellow = 20% + 35% = 55%.
so, green has then the remaining 100-55 = 45%
and again
45% = 45×1% = 45×4 = 180
or
400×0.45 = 180
Step by step
Out of 100%, 20% are red and 35% are yellow.
That means 100% - 20% - 35% = 45% are green.
We can multiply 400 beads x 45% to get how many are green ( 45% is the same as .45)
400 x .45 = 180 are green
To check your work,
You already know green beads = 180
Multiply 400 x 20% red beads = 80
Multiply 400 x 35% yellow beads = 140
Add all together 140 + 80 + 180 = 400 beads!

To find the sales tax multiply the tax rate by the cost of the product and then add to the cost.
Sales tax = tax rate * cost price

Cost price = cost of product + sales tax

Step-by-step explanation:
1. We know that each steel part has a volume of 1015 cubic centimeters, and the machinist wants to make 500 of these. Then the total volume of the steel part the machinist will make will be 1015 x 500.
--> 1015 x 500
--> 507500 cubic centimeters.
2. The density of the steel part is 7.95 grams per one cubic centimeter. Then the total density of the 500 steel parts will be 507500 x 7.95.
--> 507500 x 7.95
--> 4,034,625 grams.
3. For every kilo of steel part, the cost is $0.29. We should first change the 4,034,625 gram to kilo. Since 1000 grams is a kilo, we divide 4,034,625 by 1000.
--> 4,034,625 grams / 1000 = 4034.625 kilograms.
Now we multiply 4034.625 by 0.29 to find the total cost.
--> 4034.625 x 0.29
--> 1170.04125.
Since the question specifically asked to round it to the nearest dollar, our final answer becomes $1170.

Given that the distance and angle of elevation of the tree from P are 50 m. and 32°, and Q is 100 m. from P, we have;
a. The height of the tree is approximately 31.2 m.
b. i. The distance of Q from the base of the tree is 50•√5 m.
ii. The angle of elevation of the top of the tree from Q is approximately 15.6°
iii. The bearing of the tree from Q is 296.565°
How can the distances and bearing of the tree from Q be found?a. tan(32°) = Height/50
Height = 50 × tan(32°) = 31.243 m.
Height of the tree ≈ 31.2 m.b. i. The distance, d, of Q from the base of the tree is given by Pythagorean theorem as follows;
d = √(100² + 50²) = 50•√5
The distance of Q from the base of the tree, d = 50•√5 m.ii. The angle of elevation is given by trigonometric ratios as follows;
[tex]tan (\theta) = \frac{31.243}{50 \cdot \sqrt{5} } [/tex]
Which gives;
[tex]\theta= arctan \left( \frac{31.243}{50 \cdot \sqrt{5} } \right) \approx 15.6 ^{ \circ} [/tex]
The angle of elevation of the top of the tree from Q ≈ 15.6°iii. The angle formed at Q by the lines from Q to the point P and Q to the tree is found as follows;
Angle = arctan(50/100) ≈ 26.565°
The angle between the direction north of Q and a line from Q to the tree is therefore;
90° - 26.565° = 63.435°
The bearing, which is the angle described clockwise from the direction north of Q and the direction from Q to the tree, is therefore;
Bearing = 360° - 63.435° = 296.565°
The bearing of the tree from Q = 296.565°Learn more about bearings in mathematics here:
