Which trigonometric functions have a domain of [–1, 1]?
Answer:
A. y = arcsinx and y = arccosx
Step-by-step explanation:
edge
The trigonometric functions have a domain of [–1, 1] is sine and cosine function.
What is Domain?The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f(x) make up this set. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Given:
From the given identity, the following things can be interpreted:
cos²x = 1- sin² x
cos x = √(1- sin2x)
Since the cosine function is known to be defined for real numbers, the value contained within the root is always positive. Therefore,
1- sin²x ≥ 0
sin²x ≤ 1
sin x ∈ [-1, 1]
Similarly,
1- cos²x ≥ 0
cos²x ≤1
cos x ∈ [-1,1]

How can we find how many inches wide the coat box is?
Answer:
First we found the sum of 15.438 and 3.18. The subtract the answer from 32.476.
Option A is correct.
Step-by-step explanation:
The total width of box is = 32.476
Width of box of T-shirts = 15.438
Width of box of Socks = 3.18
We need to find width of coat box.
The width of coat box can be found as:
Total Width = Width of box of T-shirts + Width of box of Socks + width of coat box
32.476 = 15.438 + 3.18 + width of coat box
32.476 = 18.618 + width of coat box
width of coat box= 32.476 - 18.618
width of coat box = 13.858
So, The Width of coat box = 13.858 inches
First we found the sum of 15.438 and 3.18. The subtract the answer from 32.476.
Option A is correct.

Danielle wants to fill a box with dirt to start a garden if the box is 2 1/5 feet long by 1 1/3 feet wide and 1 1/2 feet deep how much dirt does Daniel need to fill up the box for her garden
Answer:
3/7 and 5/9
Step-by-step explanation:
The volume of dirt needed to fill up the box for Danielle's garden is 22/15 cubic feet.
To find the volume of dirt needed to fill up the box for Danielle's garden, we need to calculate the volume of the box.
The formula for the volume (V) of a rectangular box is:
V = length × width × depth
Given dimensions:
Length = 2 1/5 feet
Width = 1 1/3 feet
Depth = 1 1/2 feet
Now, let's convert the dimensions into improper fractions:
Length = 2 1/5 = (5 × 2 + 1) / 5 = 11/5 feet
Width = 1 1/3 = (3 × 1 + 1) / 3 = 4/3 feet
Depth = 1 1/2 = (2 × 1 + 1) / 2 = 3/2 feet
Now, plug the values into the volume formula:
V = (11/5) × (4/3) × (3/2)
Next, multiply the fractions:
V = (11/5) × (4/3) × (3/2) = 44/30 = 22/15
Now, we can simplify the fraction:
V = 22/15
The volume of dirt needed to fill up the box for Danielle's garden is 22/15 cubic feet.

Step-by-step explanation:
A constant volume of cookie dough is formed into a cylinder with a relatively small height and large radius. When the cookie dough is placed into the oven, the height of the dough decreases as the radius increases, but it retains its cylindrical shape. At time t, the height of the dough is 8 mm, the radius of the dough is 18 mm, and the radius of the dough is increasing at a rate of 2 mm per minute.
Part A: At time t, at what rate is the area of the circular surface of the cookie dough increasing with respect to time? (5 points)
Part B: At time t, at what rate is the height of the dough decreasing with respect to time?
Answer:
a) dA/dt = 125,42 mm/min
b) dh/dt = - 1,78 mm/min
Step-by-step explanation:
The volume of the cylinder is:
V(c) = π*r²*h ( r and h radius of the base and heigh respectively )
Then the surface area is: Area of the base : π*r²
Plus lateral area : h*2*π*r
A(c) = π*r² + 2*π*r*h
With the help of differentials we obtain:
dA/dt = 2*π*r*dr/dt + 2*π*h*dr/dt + 2*π*r*dh/dt (1)
In this equation and at time t we know:
r = 18 mm dr/dt = 2 mm/min h = 8 mm dh/dt = ??
dA/dt = increasing rate of the surface area ( with respect to time)
To find dh/dt we know:
V(c) is constant, then
V(c) = π*r²*h then h = V(c) / π*r²
dh/dt = - [V(c)*2*π*r*dr/dt ] / π²*r⁴
By subtitution of V(c)
dh/dt = - [ π*r²*h *2*π*r*dr/dt ] / π²*r⁴
dh/dt = - [2*π²h*r³*dr/dt ] /π²*r⁴
dh/dt = - [2*h* dr/dt ] / r
dh/dt = - 2*8*2 / 18 mm/min
dh/dt = - 1,78 mm/min
By subtitution in equation (1)
dA/dt = 2*π*r*dr/dt + 2*π*h*dr/dt + 2*π*r*dh/dt
dA/dt = 2*π*18*2 + 2*π*8*2 + (- 2*π*18*1,78 )
dA/dt = 226,20 + 100,53 - 201,31
dA/dt = 125,42 mm/min
Following are solutions to the given points:
Formula:
Cylinder volume [tex]v = \pi r^2 h...............(i)[/tex]
[tex]\to \frac{dr}{dt} = 2 \frac{mm}{min}\\\\ \to \frac{dh}{dt} = -2 \frac{mm}{min}\\\\ \to h=8\\\\ \to r=18 \\\\[/tex]
Part A:
Calculating the circular area of the surface:
[tex]\to A=\pi r^2\\\\[/tex]
So, [tex]\frac{dA}{dt}=2 \pi r \frac{dr}{dt}.........(ii)[/tex]
Therefore
[tex]\to \frac{dA}{dt}= 2\pi \times 18 \times 2= 72 \pi \ \frac{mm^2}{min}\\\\[/tex]
