Answer:
6.1 s
Step-by-step explanation:
h = -16t² + 600
When the sack reaches the ground, h = 0.
0 = -16t² + 600
16t² = 600
t² = 600/16
t² = 37.5
t = 6.1 s
It will take 6.1 s for the sack to reach the ground.
Step-by-step explanation:
"collinear" means simply that they are all on the same line.
and that solves the problem right away, right ?
because as we know EF (the long distance between the outermost points) is 14 in, and EC (which is s part of the long distance) is 9 in, that means
CF (the rest of the long distance) = EF - EC = 14-9 = 5 in
AC = 2 BD
Distance BD = √[(2.5+1)^2 +(3-3)^2]
Distance BD = √(3.5)^2
Distance BD = 3.5
AC = 2 * 3.5 = 7
Answer
d. 7
Answer:
A. 7
Step-by-step explanation:
- <em>If a number has exactly two factors, 1 and itself, the number is a prime number. </em>
- <em>The only prime number below is 7</em>
7= 1*7
8= 1*8= 2*4
9= 1*9= 3*3
10= 1*10= 2*5
