Givens
a = 4.4 m/s^2 This is an acceleration and is positive.
vi = 10.2 m/s
t = 4.2 seconds
vf = ????? The cruising speed in this case is vf.
Formula
a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula
Solve
4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2
4.4 * 4.2 = vf - 10.2
18.48 = vf - 10.2 Add 10.2 to both sides
18.48 + 10.2 = vf 8.28 is the second best answer.
28.68 = vf This is your cruising speed.
C <<<< Answer
Answer:
117
Step-by-step explanation:
The formula for a triangle is base times hight divided by two. So, 13 x 18 = 234, and 234/2 = 117
Answer:
Option D. {–7, 7}
Step-by-step explanation:
3n^2 = 147
First, divide both side 3
n^2 = 147/3
n^2 = 49
Next, rearrange the variables to one side of the equation as shown below:
n^2 — 49 = 0
n^2 — 7^2 = 0
The above is now difference of two squares. This can be solve by doing the following:
(n — 7)(n + 7) = 0
n — 7 = 0 or n + 7 = 0
n = 7 or n = —7
