Answer:
As space expanded, the universe cooled and matter formed
Explanation:
Amount of time=2.5 hoursamount of time after speed increase=2 hourslet x=the initial speedlet t=the amount of hourslet y=the new speed let z=distance therefore xt=zyt=zplugging everything in,x(2.5)=zy(2)=zusing substitution y=20+x2.5x=z(20+x)(2)=z40+2x.5x=40x=80y=x+20y=100
Answer:
Explanation:
If you multiply (x - k)(x + k), you get 
which is equal to 
. Now you can see that 
must be equal to 
which is equal to 
. Now we just need to solve 
. The final answer is 
.
The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.
The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

Explanation:
The deeper you go in both Earth's interior and the swimming pool the greater the pressure grows. The difference is the swimming pool contains, mostly liquid and Earth's interior contains mostly solids.
