Answer:
vi = 25.28 m/s
Step-by-step explanation:
a = -9.4 m/s²
x = 34 m
vf = 0 m/s
vi = ?
We can apply the equation
vf² = vi² + 2*a*x
⇒ vi = √(vf² - 2*a*x)
⇒ vi = √((0 m/s)² - 2*(-9.4 m/s²)*34 m)
⇒ vi = 25.28 m/s
the quickest way to do this would be to multiply 1,375 by 3 and then add 2.
1,375 * 3 = 4,125 + 2 = 4,127
correct!

Depends on your question...
If your question is r + 0.12 = 0.20 then do this:
Subtract 0.12 from both sides
r = 0.08
The answer is B.
If your question is r - 0.12 = 0.20 then do this:
Add 0.12 on both sides
r = 0.32
The answer is A
So it depends on your question :P
Answer:
4n + 8 = -48
n = -14
Step-by-step explanation:
Using key words from the problem, you can set up an equation with the proper operations to solve for the variable. Product = multiplication, so the 'product of 4 and a number' = 4n. Increased = addition, so increased by 8 = 4n + 8. The word 'is' means equal to, so:
4n + 8 = -48
In order to solve for 'n', you use inverse (opposite) operations and whatever you do to one side of the equation, you do to the other:
Subtract 8: 4n + 8 - 8 = -48 - 8 or 4n = -56
Divide 4: 4n/4 = -56/4
Solve for 'n': n = -14
