Well, if point C is dilated by 5/3, C' should be (3*5/3, -6*5/3)
This is equivalent to Option A, (5, -10)
X=cubic root 2/27
Glad to help
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
Yes. Any number that can be written as a fraction is defined as rational.
