Answer:
The last option
Step-by-step explanation:
This definitely isn't a parallelogram, so you can knock both of the yes answers out. One of the rules of parallelograms are that if there is 1 right angle then all four need to be right angles, even if the others are supplementary if the right angle rule is not followed then the shape is not a parallelogram.
Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
Answer:
answer is A
Step-by-step explanation:
according to the rules of equation of a - goes to next side it became +
so the answer is 7x-14
Answer:
The length of the diagonal have to be 43.4 feet
Step-by-step explanation:
we know that
For the corner to be a right angle, the length of the diagonal must satisfy the Pythagorean Theorem
Let
x ----> the length of the diagonal
so
therefore
The length of the diagonal have to be 43.4 feet
