After t seconds, a ball in the air from the ground level reaches a height of h feet given by the equation h= 144t-16t^2 . After

Effectus [21]

H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )

Answer: the ball hit the ground in 9 s.

Solve these equation<br><br>4(3-x)=(1-2x)

serg [7]

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

$:\implies\tt{4(3 - x) = (1 - 2x)}$

$:\implies\tt{(12 - 4x) = (1 - 2x)}$

$:\implies\tt{12 - 4x = 1 - 2x}$

Combining like terms, we get,

$:\implies\tt{12 - 1 = - 2x + 4x}$

$:\implies\tt{11 = 2x}$

$:\implies\tt{2x = 11}$

$:\implies\tt{x = \frac{11}{2} }$

$:\implies\tt{x = 5.5}$

The value of x is 5.5

Answer:

The measurement of angle B is 135°

The measurement of angle A is 60°

The measurement of angle C is 75°

Step-by-step explanation:

Angle A is the same value of 60, Angle B is pretty much just 180 - 45, and so is angle C.
