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
A negative times a negative is a positive. I am not sure if that's the question, but hopefully that helps if it was.
Answer:
m∠A = 65°
Step-by-step explanation:
<em>Opposite angles of the quadrilateral add up to 180</em>.
This means x + 148 = 180 -> <em>x = 32</em>.
m∠A = 2x + 1 -> 2(32) + 1
m∠A = 65°.
Answer:
The next three terms are 10, 12.5 and 15
Step-by-step explanation:
I. As you can see 5 and 7.5 is came from 5, 5 + 2.5
So given y = 5 + 2.5( x - 1 ) when y is output, x is term
II. Perform x = 3, 4, 5
So y = 5 + 2.5( 3 - 1 )
= 5 + 5
3rd = 10
y = 5 + 2.5( 4 - 1 )
= 5 + 7.5
4th = 12.5
y = 5 + 2.5 (5 - 1)
= 5 + 10
5th = 15

Answer:
8-2x I think
Step-by-step explanation:
You would first divide 39 by 3, ( 2 + 1 = 3) and get 13.
You would next take 5 away from 13 and get 8.
Then you have your answer, because you cannot simplify it more because both the numbers do not have the same variable.
