differentiate tan inverse of x÷a
Answer:
Expression Derivatives
y = tan-1(x / a) dy/dx = a / (a2 + x2)
y = cot-1(x / a) dy/dx = - a / (a2 + x2)
y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)
y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)
What’s the volume and surface area
Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

[tex]170[/tex]
Step-by-step explanation:
The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.
[tex]wx = 2(42x + 1)[/tex]
We can add up that and the other arcs to 360.
[tex]2(42x + 1) + 29x - 1 + 65x + 3[/tex]
[tex]84x + 2 + 29x - 1 + 65x + 3 = 360[/tex]
[tex]178x + 4 = 360[/tex]
[tex]178x = 356[/tex]
[tex]x = 2[/tex]
Plug in 2 for WX.
[tex]84(2) + 2 = 170[/tex]

Can someone please explain the area of a circle in the simplest way possible, no links
So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.

Answer:
7)Bagel costs $3.5 and muffin cost $1.25
8) Ticket is $9 while snacks are $2
9) Correct because left hand side is zero
10) Correct because they both have same slope and same y-intercept
Step-by-step explanation:
7) Let bagel be x and muffin be y.
Thus;
For Aaron;
x + 3y = 7.25 - - - (1)
For bee;
x + 2y = 6 - - - (2)
Subtract eq 2 from eq 1 to get;
y = 1.25
Put 1.25 for y in eq 2;
x + 2(1.25) = 6
x + 2.5 = 6
x = 6 - 2.5
x = 3.5
Bagel costs $3.5 and muffin cost $1.25
8) Let movie ticket be x and snacks be y.
Thus;
2x + 3y = 24 - - - (1)
3x + 4y = 35 - - - (2)
Multiply eq(1) by 3 and eq(2) by 2 to get;
6x + 9y = 72 - - - (3)
6x + 8y = 70 - - - (4)
Subtract eq 4 from eq 3 to get;
y = 2
Put 2 for y in eq 3;
6x + 9(2) = 72
6x + 18 = 72
6x = 72 - 18
6x = 54
x = 54/6
x = 9
Ticket is $9 while snacks are $2
9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.
Thus, no solution exists because we can't isolate the variable to get an answer.
10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.
In this case, their y-intercept which is when x is 0 is;
3(0) + y = 9
y = 9
Their slope is also the same equal to 3.

Use either the shell method or the disk/washer method to find the volume of the solid (Calculus Help!!!)
Integrating with shells is the easier method.
V = 2π ∫₁³ x (√x + 3x) dx
That is, at various values of x in the interval [1, 3], we take n shells of radius x, height y = √x + 3x, and thickness ∆x so that each shell contributes a volume of 2π x (√x + 3x) ∆x. We then let n → ∞ so that ∆x → dx and sum all of the volumes by integrating.
To compute the integral, just expand the integrand:
V = 2π ∫₁³ (x ³ʹ² + 3x ²) dx
V = 2π (2/5 x ⁵ʹ² + x ³) |₁³
V = 2π ((2/5 × 3⁵ʹ² + 3³) - (2/5 × 1⁵ʹ² + 1³))
V = 4π/5 (9√3 + 64)

Azim wants to buy a tablet computer that is priced at 180.50. If sales tax rate on the computer is 8%, how many dollars and cents will Azim spend on the sales tax?
Answer:
$14.44
Step-by-step explanation:
I'm pretty sure it's 14.44 because It says only the sales tax not the whole price together so you would take 8% turn it into .08 and multiply 180.50 by .08 and get 14.44 which is the sales tax. And if you were looking for the total it would be 194.94 but that's not what this question is asking(:

What are the dimensions of the rectangle?
A rectangle has an area of 40 square units. The length
is 6 units greater than the width
O 8 by 5
10 by 4
11 by 9
13 by 7
Answer:
its b
Step-by-step explanation:
The requried dimensions of the rectangle are 10 by 4. Option B is correct.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
To solve the problem, we can use the formula for the area of a rectangle, which is:
area = length x width
We also know that the length is 6 units greater than the width, which we can express as:
length = width + 6
We can substitute this expression for length into the formula for area, giving us:
area = (width + 6) x width
area = width² + 6width
We are given that the area is 40 square units, so we can set up the equation:
40 = width² + 6width
We can rearrange this equation into the standard quadratic form:
width² + 6width - 40 = 0
We can then use the quadratic formula to solve for the width:
width = (-b ± √(b² - 4ac)) / 2a
Plugging in the values of a, b, and c from the quadratic equation above, we get:
width = (-6 ± √(6² - 4(1)(-40))) / 2(1)
width = (-6 ± √(196)) / 2
width = (-6 ± 14) / 2
So we have two possible values for the width:
width = (-6 + 14) / 2 = 4
or
width = (-6 - 14) / 2 = -10
Since the width cannot be negative, we can reject the second solution. Therefore, the width of the rectangle is 5 units.
We can use the expression for the length in terms of the width to find the length:
length = width + 6 = 4 + 6 = 10
Therefore, the dimensions of the rectangle are 10 by 4.
