I think B is the only polynomial because A and C both have roots that aren't supposed to be in polynomial expressions and you can't divide (D)
I think that the answer you are looking for is 0.3
Answer:
40
Step-by-step explanation:
6% of number = 6/100 × x = 6x/100 = 3x/50
Sum of the number and 6% of itself = 42.4
x + (3x/50) = 42.4
(50x+3x)/50 = 42.4
53x = 42.4 × 50
53x = 2120
x = 2120/53
x = 40
The graph of y=tanx+1 crosses the y-axis at (0,1).
I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.
