Would you like me to help walk you through this with you figuring out the work?
Or would you prefer just an answer in math form with me explaining it along the way?
<span>h(t) = 80t – 16t^2
When you are on the ground we have zero height, h(t) = 0. This is saying that at some amount of time we will call t, the object will hit the ground. Now we solve for t to get that time
so we sub h(t) for 0.
0=80t-16t^2 move the -16t^2 to the other side
16t^2=80t divide both sides by t
16t=80 divide both sides by 16
t=5
Now... it is important to realize that there are going to be 2 answers to this equation as you have a t^2. The other answer is 0. Obviously, unless the object started on the ground, the time to hit the ground is not 0 and that answer is ruled out.

Answer:
0, because 5 divided by 8 is 0.625. 0.625 is not a whole number. 5/8 = 0.625
Volume is area of the triangle multiplied by length:
area = 1/2*base*height
= 1/2*7*2
=7
therefore V = 7*18
= 126
Answer:
We can not solve for a unique cost for each soldier.
Step-by-step explanation:
Let x be the daily cost for legionaries and y be the daily cost for archers.
Upon using our given information we will get a system of linear equations as:
Now we will solve for x from our 2nd equation,
Now we will substitute this value in our 1st equation.
We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.
Answer:
62.5 miles per hour
Step-by-step explanation:
Given data
distance= 125m
time= 2 hours
We know that
speed= distance/time
Subsitute
Speed= 125/2
speed= 62.5 miles per hour
