A.
For this case, let us set the variables:
s = 0 (final destination on the ground)
t = unknown
vo = 0
so = 8000 ft
Using the equation, we calculate for t:
0 = -16 t^2 + 0t + 8000
t = 22.36 s
B.
For this case:
s = unknown
t = 22.36 s
vo = 600 miles/hr = 880 ft/s
so = 0
Using the equation, we calculate for s:
s = -16*(22.36)^2 + 880*22.36 + 0
s = 11, 677.29 ft = 2.21 miles
You can write the expression by reading it step by step. “The quotient of 10 and a number (x)” means 10/x. “Increased by 6” means +6. So, the expression is: 10/x+6 or (10/x)+6 to makes it easier to look at. Hope this helped!
It would be 28:20
7=5=12
48/12=4
7x4=28
5x4=20
12- 3+16 - 37 - (-20)
=9+16-37-(-20)
=25-37-(-20)
=-12-(-20)
=8
(therefore ur answer would be 8)
Hello!
We have two expressions below.
7(6+2)
2(7)+6(7)
The area is 56 units squared.
I hope this helps!
