Domain definition in math
Answers
The output values are called the range.
Domain → Function → Range
Example: when the function f(x) = x2 is given the values x = {1,2,3,...} then the domain is simply those values {1,2,3,...}

180(.6) because 40% off is 0.4 and what is left over is 60% or 0.6. When you multiply this you get 108. 5% sales tax is a 5% increase, so multiple 108(1.05) and you get $113.40.
Select one:
a. B = 23.7°, C = 143.3°, c ≈ 23.3
b. B = 23.7°, C = 123.3°, c ≈ 17.5
c. Cannot be solved
d. B = 23.7°, C = 123.3°, c ≈ 29.2

a / sin A = b / sin B
19 / sin 33 = 14 / sin B
B = arcsin (14 * sin 33 / 19 )
B = 23.66° = 23.7°
Since the sum of all interior angles of a triangle is 180°, we can solve for angle C like so:
C = 180° - 23.7° - 33°
C = 123.3°
Using sine law to solve for side c:
a / sin A = c / sin C
c = (a*sin C)/sin A
c = 29.157 = 29.2
Therefore, among the choices, the correct answer is D.
Answer:
D.

When Ivan divides his coins into groups of 2 nickels and 1 quarter, worth $0.35, he find that he has $8.75/$0.35 = 25 such groups.
Ivan has 25 quarters and 50 nickels.
Answer:
- The number of nickels coins are : 50
- and the number of quarter coins are: 25
Step-by-step explanation:
Let n denote the number of nickels.
and q denote the number of quarters.
1 nickel=0.05 dollar
and 1 quarter=0.25 dollar
Hence, we have:
0.05n+0.25q=8.75
( Since, Ivan has $8.75 in nickels and quarters in his desk drawer )
On multiplying both side of the equation by 100 we have:
5n+25q=875
on dividing both side of the equation by 5 we have:
n+5q=175-----------------(1)
Also, n=2q---------------(2)
( Since, the number of nickels is twice the number of quarters )
Hence, on putting equation (2) in equation (1) we have:
2q+5q=175
i.e.
7q=175
i.e. q=25
and on putting the value of q in equation (2) we have:
n=50

The area of original square is 16 centimetre square.
What is an area?
The area is the region bounded by the shape of an object.
Let consider 'a' as the side of the original square.
When it fold vertically then the top and bottom sides will be half of the original side.
The perimeter of folded square = 12 cm
i.e. (2* 0.5a)+ 2a =3a =12 cm
Then, a=4cm
The area of original square is given by a^2.
Then, a^2 = 4*4 =16
Hence, 16 centimeter is the area of the original square.
