<u>Given</u>:
The height of an object project upward is given by the polynomial
where t represents the time, in seconds.
We need to determine the height after t = 2.5 seconds.
<u>Height of an object:</u>
The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;
Simplifying, we get;
Thus, the height of an object is 140 feet.
Answer:
Point form : (- 2/3, 10/9)
Equation form : x=- 2/3, y=10/9
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
I hope this helps you out. :)
Answer:
100 minutes
Step-by-step explanation:
3 hours= 180 min
180/9 = 20
20 x 5 =100 min
Let x = Class A
Let y = Class B
Let z = Class C
Equations from problem:
x - 160 = y
2/3x = z
y + 92 = z
Solving through substitution:
2/3x = y + 92
2/3x = (x - 160) + 92
2/3x = x - 68
-1/3x = -68
3(-1/3x) = 3(-68)
-x = -204
x = 204
Now substitute x in the first equation to get y:
204 - 160 = y
44 = y
44 = Class B
There are 44 folded paper cranes in Class B.
