Answer:
x+6
Step-by-step explanation:
The given expression is (2+x)+4.
The associative property is :
(a+b)+c= a+(b+c)
Here,
a = 2, b = x and c = 4
So,
(2+x)+4 = 2+(x+4)
= x+6
So, the equivalent expression is x+6.
For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s
ok i think your answer will be from least to greatest it would be this 3 1/5, 3.1, 3.5, 4.2
Hope i helped let me know if i got it right if not i am very sorry.
Answer:
4 degrees.
Step-by-step explanation:
A complete circle has 360 degrees.
(4/360) of a circle = (4/360) * 360 degrees = 4 degrees
300% if 5 is 15. 30% of 5 is 1.5 not 15. That is an error. Hope this helps!
