Answer:
145 degrees
Step-by-step explanation:
All angles in a parallelogram always add up to 360 degrees when added together.
And all angles are the same as the angle adjacent to them.
Since we already know that angle DAB is 35, then the adjacent angle BCD, is also 35.
And since we know that all the angles add up to 360, we just gotta do the math.
35 + 35 = 70 and when you subtract 70 from 360 you get 290. Now all you have to do is divide 290 by 2, and you get 145, which is also the same as angle ABC since they are adjacent to each other.
Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
i hope this work for you

Answer:
Division is not closed
explanation:
addition and subtraction are closed for polynomials because the result of adding and multiplying two polynomials is always another polynomial. Division on the other hand is not closed. If you divide two polynomials, the result is not always a polynomial.
