If “the notation arcsin x represents the inverse function to sine” is true or false.
Answers
If “the notation arcsin x represents the inverse function to sine” is true when the sine function is to the interval [ -pi/2, pi/2 ].
What is the sin function?The sine function is one of the three primary functions in trigonometry, the others being cosine, and tan functions.
The confusion is compounded by the fact that we use the notation sin⁻¹(x) interchangeably with arcsin(x), and we call it the inverse sine.
Here is a counterexample disproving your given statement:
Let x = π.
The value π is in the domain of sin(x).
arcsin[sin(π)] = arcsin(0) = 0
arcsin[sin(π)] ≠ π
Therefore arcsin(x) is not the inverse of sin(x).
If you restrict the sine function to the interval [ -pi/2, pi/2 ]. Otherwise, arcsin will not be a function.
Hence, If “the notation arcsin x represents the inverse function to sine” is true when the sine function is to the interval [ -pi/2, pi/2 ].

solve b - 4 = 3.
solve -32 = 8w
solve n
— = -4
7
Answers
Answer:
see below
Step-by-step explanation:
b - 4 = 3
Add 4 to each side
b - 4+4 = 3+4
b = 7
-32 = 8w
Divide by 8
-32/8 = 8w/8
-4 = w
n/7 = -4
Multiply by 7 to each side
n/7 *7 = -4*7
n = -28
1. b = 7
2. w = -4
3. n = -28
Step-by-step explanation:
1. b - 4 = 3
Tip: Whenever there’s a number being subtracted or added, it’s best to make that number a 0
Step 1. Add 4 to both sides
b - 4 = 3
b + 4 = +4
b = 7
—————————————
2. -32 = 8w
Step 1. Isolate the variable
(by dividing both sides by 8)
w = -32/8
w = -4
—————————————
3. n/7 = -4
Step 1. Multiply 7 x -4
n = -28
8. What is the solution to 4(1/2x+7)=12?
Answers
Answer:
x=-8
Step-by-step explanation:
4(1/2x+7)=12
Divide each side by 4
4/4(1/2x+7)=12/4
(1/2x+7)=3
Subtract 7 from each side
1/2x+7-7=3-7
1/2x = -4
Multiply each side by 2
1/2x*2 = -4*2
x = -8
Answer:
-8
Step-by-step explanation:
Divide both sides by 4 which will give you 1/2x+7=3
Then multipy both sides by 2 which will then give you x+14=16
Then move the constant = x=6-14
6-14 is -8 which will give you x=-8

How would I answer this: How many minutes are in a 30-day month.... use vertical multiplication to get the right answer
Answers
Answer:
43,200 minutes in 1months or 30 days
There are 43200 minutes in one month.
What is multiplication?The basic explanation of multiplication is adding a number, with respect to another number, repeatedly.
Given that, How many minutes are in a 30-day month,
We have, 60 minutes in 1 hour
And, 24 hours in 1 day,
Then, number of minutes in 1 day = 60 × 24 = 1440 minutes
Therefore, in 1 month = 1440 × 30 = 43200 minutes
Hence, there are 43200 minutes in one month.

Find the measure of each angle indicated.
A) 25°
C) 35°
B) 45°
D) 40°
Answers
Answer:
here's the answer to your question
Answer:
D) 40
Step-by-step explanation:
To solve the question you can use the knowledge that every triangle has a total of 180 degrees. Two of the angles are known one is 50 and the other is 90. We know one is 90 because of the square around the angle. Then, you can set up an algebraic equation to solve. We know that 50+90+x=180, so solve for x for the final answer of 40.

Antonia and Aleena both bought a book that cost £3.50 each. How much change did they get from £10.00?
£6.50
£2.00
£3.00
Answers
Answer:
They got 3.00 back
Step-by-step explanation:
Since they both bought a book it means you have to double the price of one book.
3.50+3.50=7.00
Then since you are looking for the difference of 10.00 you would subtract it.
10.00-7.00=3.00

solve the triangle. Round decimal places to the nearest place
Answers
Explanation:
To find the remaining angle of this triangle, you may do 180 - (24+66) = 90, since the sum of angles in any triangle must equal to 180.
To find the remaining sides, you may use the sine rule to find BC:
sin(Angle)/opposing side = sin(Angle)/opposing side
1) sin90/43 = sin24/x
2) 1/43 = 0.4067/x
3) x = 17.48
4) x ≈ 17
You may also use the sine rule to find side AC:
1) sin90/43 = sin66/x
2) 1/43 = 0.9135/x
3) x = 39.28
4) x ≈ 39

What is the area of the shaded region
round your final answer to the nearest hundredth
Answers
The area of the shaded region is 44.24\ cm^{2}44.24 cm2
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the circle minus the area of rectangle
step 1
Find the area of circle
The area of the circle is equal to
A=\pi r^{2}A=πr2
we have
r=4\ cmr=4 cm
substitute
A=\pi (4)^{2}A=π(4)2
A=16\pi\ cm^{2}A=16π cm2
step 2
Find the area of rectangle
The area of rectangle is equal to
A=(3)(2)=6\ cm^{2}A=(3)(2)=6 cm2
step 3
Find the difference
16\pi\ cm^{2}-6\ cm^{2}16π cm2−6 cm2
assume
\pi=3.14π=3.14
16(3.14)\ cm^{2}-6\ cm^{2}=44.24\ cm^{2}16(3.14) cm2−6 cm2=44.24 cm2

Step-by-step explanation:
always remember that
volume of a rectangular prism = area of the base x depth
AND
volume = 72
depth. = 3
it means we have to multiply 72 with 3
so we get
72 x 3 = 216
