Answer:
The domain of function 
is set of all real numbers.
Domain: (-∞,∞)
Step-by-step explanation:
Given:
the domain of both the above functions is all real number.
To find domain of :
Substituting functions 
and 
to find
The product can be written as difference of squares. ![[a^2-b^2=(a+b)(a-b)]](https://tex.z-dn.net/?f=%5Ba%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29%5D)
∴ 
The degree of the function is 2 as the exponent of leading term 
is 2. Thus its a quadratic equation.
For any quadratic equation the domain is set of all real numbers.
So Domain of is (-∞,∞)
Answer:
360 in.
Step-by-step explanation:
In order to get this answer, you have to multiply 5 and 8 by 3 because the drawing is 1/3 of the actual flag.
5 x 3 = 15
8 x 3 = 24
So, 24 x 15 = 360 in.
Hope this helps! :)
Answer:
336 ft²
Step-by-step explanation:
The rectangle is 13 ft long and 8 width that means we have two walls 8* 9 and two walls 13*9
Total walls area is
2*8*9 + 2*13*9 = 144 + 234 = 378 ft²
then we subtrac , areas of door, closet and windows
3 * 6.5 = 19,5 ft²
3 * 6,5 = 19,5 ft²
2 * 1,5 = 3 ft²
42 ft²
Then area to paint 378 - 42 = 336 ft²
Answer:
y = 4/3x - 8
Step-by-step explanation:
slope of given line is -3/4 so the perpendicular slope is 4/3
line goes through (6, 0)
y = mx + b
0 = 4/3(6) + b
-8 = b
y = 4/3x - 8
