A basketball is thrown with an initial upward velocity of 30 feet per second from a height of 6 feet above the ground. The equat

ion h=-16t^(2)+30t+6 models the height in feet t seconds after the basketball is thrown. After the ball passes its maximum height, it comes down and then goes into the hoop at a height of 10 feet above the ground. About how long after it was thrown does it go into the hoop?

For this case we have the following equation:
 h = -16t ^ (2) + 30t + 6
 We substitute the value of h = 10 in the equation:
 10 = -16t ^ (2) + 30t + 6
 Rewriting we have:
 0 = -16t ^ (2) + 30t + 6-10
 0 = - 16t ^ (2) + 30t - 4
 We look for the roots of the polynomial:
 t1 = 0.144463904
 t2 = 1.730536096
 "the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
 t = 1.730536096
 Answer:
 
It goes into the hoop after:
 t = 1.73 seconds

Is point (2,1) on the the line represented by the equation x+2y=5
Sphinxa [80]
To check if this point lies on the line, plug in a 2 for x and a y for 1 and solve

x+2y=5
2+2(1)=5
4=5

Since this statement isn't true, then the point doesn't lie on the line

Hope this helps

1. 36(a+b)^2 - 49(a-b(^2
Brums [2.3K]

Answer:

-13a^2 + 170ab - 13b^2.

Step-by-step explanation:

1.  36(a+b)^2 - 49(a-b)^2

This is the difference of 2 squares: a^2 - b^2 = (a + b)(a - b).

36(a+b)^2 - 49(a-b)^2

= (6(a + b) + 7(a - b))(  6(a + b) - 7(a - b))

= (6a  + 7a + 6b - 7b)( 6a - 7a + 6b + 7b)

= (13a - b)(-a + 13b)

If you require the expansion of this it is:

-13a^2 + 170ab - 13b^2.
