Ur whole number is 17...now look at the next number to the right....if it is 5 or above, u round that 17 to 18....if it is 4 or below, that 17 stays the same. And since the next number is 6, u r going to have to round the 17 up to 18 (the nearest whole number)
Answer:
x=17 <A= 114
I think this is the answer
Step-by-step explanation:
22. 30 degrees because line DB bisects(meaning cuts in half) angle ABC so DBC should be 30 degrees because 30+30 is 60 which is what angle ABC is.
23. 60 degrees because if we assume that it is a parallelogramand that the opposite angle are congruent.
24. 120 degrees because a quadrilatteral has sides that will equal to 360 degrees, and I said that a parallelogram will have its opposite angles congruent we take away 120 from 360 (from the previous angles ABC and BCD) we end up with 240, we divide 240 by 2 and end up with 120 degrees
25. 60 degrees. I found that angle DCB is 120 degrees so angles DCB and DCE are supplementary(add up to 180 degrees) and we subtract 120 from 180 which is 60 degrees.
26. 60 degrees vertical to angle DCE.
27. 120 degrees supplementary to DCE
Answer:
I didn't know if you meant which one is a function, and which one isn't so I just went with what the picture said:
A) is not a function
When the object lands, the height is 0
0 = -4.9t^2 + 19.6t + 58.8
0 = -4.9(t^2 - 4t - 12)
0 = (t - 6)(t + 2)
t - 6 = 0
t = 6
t + 2 = 0
t = -2....cant be this one because it is negative
ur answer is 6 seconds
