Answer:

z = 80

Step-by-step explanation:

A quadrilateral has angles that sum to 360 degrees

E + C+ G+F = 360

100+60+120+F = 360

Combine like terms

280+F = 360

F = 360-280

F = 80

We know that ABCD is similar to FECG

That means  the measure of A =  measure of F

z = 80

Andre hit a golf ball from the ground and its movement follows the equation hbracket(t)=-16sup(t,2)+44t, where t is the time in
Natasha2012 [34]

Answer: the golf ball with hit the ground again after 2.75 seconds

Step-by-step explanation:

The movement of the golf ball from the ground follows the equation h(t)=-16t^2+44t,

where t is the time in seconds, and h(t) is the height of the ball at a given time t

By the time the golf ball hit the ground, the height from the ground would be zero. This means that we would equate the quadratic equation to zero. It becomes

-16t^2+44t = 0

Dividing both sides by t

16t^2/t = 44t/t

16t = 44

t = 44/16

t = 2.75

(-5)^{-6}(-5)^9

= (-5)^{-6+9}

= (-5)^{3}



(4 \times 10^{10})(9 \times 10^{-6})

= 36 \times 10^{10-6}

= 36 \times 10^{4}
