Answer:
30 square ft (i don't know how u write it haha)
Step-by-step explanation:
area of a rectangle is l×w
4×3=12
since the scale is 1:30
then 12×30=360 in
360 in = 30 Square ft
75) The domain is all values of x and range is all values of y. Given this, domain is -1 <u><</u> x <u><</u> 6. Range is 1 <u><</u> y <u><</u> 5. It is not a function because it does not pass the vertical line test. (Shown in image. Blue line is the vertical line and green line is the line shown based on the graph.)
76) The ordered pairs are:
- (0, 1)
- (1, 2)
- (2, 3)
- (-1, 4)
- (6, 5)
We are given with th equation <span>y = 3x2 – 12x + 12. In this respect, we expect that this is a parabola and that the vertex does not lie on (0,0). Since the power or degree is 2, it is expected that per value of y, there are two equivalent x's in the plot. You can verify it in the graph.</span>
Answer:
19. (-∞,-5)U(-5,2)U(2,∞)
20. (-∞,-6)U(-6,4)U(4,∞)
21. (-∞,10)U(-10,3)U(3,7)U(7,∞)
Step-by-step explanation:
To summarize these three equations, ignore the numerators for every three equations listed, flip the + and - for each side to get the x values. You have to put the values from smallest to largest in order to state the domain. You need this sign -> U for the answers.
