Answer:
23.7m
Step-by-step explanation:
Given parameters:
Time taken = 2.2s
Acceleration due to gravity = 10m/s
Unknown:
Depth of the well = ?
Solution:
To solve this problem, we simply apply one of the motion equations;
S = ut + 
gt²
where S = depth of the well
u = initial velocity
t = time taken
g = acceleration due to gravity
Input the parameters and solve for S;
Note initial velocity = 0;
S = x 9.8 x 2.2²
S = 23.7m
Answer:
The pattern: 1 3 5 7 9 11 13 15 ..........
Step-by-step explanation:
f(n) = 2n + 1
F(0) = 1
f(1) = 2 * 1 + 1 =3
f(2) = 2 * 2 + 1 =5
f(3) = 2 * 3 + 1 = 7
The pattern: 1 3 5 7 9 11 13 15 ..........
Answer:
Step-by-step explanation:
You want to begin by making each fraction have the same common denominator. The LCF (least common factor) is 77. So, knowing this, we can now multiply the fractions that need to have a denominator of 77.
1. 5/7*11/11=55/77
2. 9/11 * 7/7 =63/77
Now we can add
55/77 + 63/77 + 21/77 = 139/77 or 1.805194805
Answer:
x = 0
Step-by-step explanation:
10a+10x=10a+x
10a+10x-10a=10a+x-10a
10x=x
10x-x=x-x
9x=0
9x/9 = 0/9
x = 0
Average speed=total distance / total time....
s=25/1.5=50/3mph (16 2/3 mph)
So you traveled an average of 2/3 mph greater than your record pace...
