Well a perfect square looks like this:
6 x 6
2 x 2
So the number 72 is between the PRODUCT of two perfect squares such as those.
One product has to be above 72, and the other below it.
So lets multiply.
8 x 8 = 64
9 x 9 = 81
Oh look at that, 72 is between 64 and 81.
C. I and II only
The absolute value has to be greater than negative q. And p must be greater than the absolute value of q.
Answer:
5.2 seconds
Step-by-step explanation:
We want to determine the value of x when h(x) = 0
:
-16x^2 +83x + 4 = 0
:
use quadratic formula to determine the value for x
:
x = ( -83 + sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = −0.047753182
:
x = ( -83 - sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = 5.235253182
:
we want the positive value for x since time runs forward
:
the ball hung in the air for approx 5.2 seconds
Answer:
Step-by-step explanation:
7-4=3
now let's change the denominator by finding the lcd (lowest common denominator)
<em>factors of 3:</em> 3, 6, 9, 12...
<em>factors of 6:</em> 6, 12, 18, 24...
both 3 and 6 has 6 as their lcd
3 x 2= 6
1/6 -4/6= -3/6
REDUCE
-1/2
3-1/2
2 1/2
