If a gain of 5 yards is shown by 5, what does -5 mean?
Answers
Step-by-step explanation:
Think of all possible numbers walking back and forth, positive means walking forward, negative means walking backwards. You start at zero, so 5 represents walking 5 yards forward. This would mean that negative 5 means walking backwards, it would still be five yards. Since 5 is a gain of 5 yards, -5 would mean a loss of 5 yards.

I can tell by looking that there's no easy way to factor the left side,
so we'll have to use the Quadratic formula.
Before doing that, let's just take a look at the discriminant:
( B² - 4AC ) = (9) - (4 x 3 x 1) = (9 - 12) = -3 .
The discriminant is negative, so we know that the roots will be complex conjugates.
Again: x² + 3x + 3 = 0
x = (1/2) [ -3 plus or minus the square root of (-3) ]
x = -3/2 + (1/2) j√3
and
x = - 3/2 - (1/2) j√3

=> b + 3 > 12
Now,let’s combine this into an expression:
=> 8 < b+3 < 12
=> (8 - 3) < b < (12 - 3)
=> 5 < b < 9
Thus, the answer in the given situation is 9 because 9 is greater than 8 butless than 12.

Answer:
The formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time is given as
Step-by-step explanation:
Given:
To Find:
bf = ?
Solution:
Acceleration:
Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.
In formula, this is written as:
Where,
'a' is the Acceleration.
'vf' is the final velocity.
'vi' is the initial velocity.
't' is the time it takes for the object to accelerate from vf to vi
Here it is given as
So,
Where,
'a' is the Acceleration
'bf' is the final velocity.
'v1' is the initial velocity.
't' is the time it takes for the object to accelerate from bf to v1.
On Solving the above equation 'bf' we get
....As required
Final answer:
In physics, the formula bf = a + v1 is used to calculate the final velocity in terms of the initial velocity, acceleration, and time. If acceleration is zero, final and initial velocities are equal, pointing to constant velocity. If acceleration is negative, the final velocity is less than the initial, indicating deceleration.
Explanation:
The equation a = bf - v1 is used to calculate acceleration, defined as the change in velocity over a period of time. To solve for the final velocity, bf, we simply need to rearrange the equation.
So, bf = a + v1. This equation tells us that the final velocity is equal to the sum of the initial velocity and the acceleration.
Other insights we can gather from this equation include: if acceleration is zero, the final and initial velocities are equal, pointing to constant velocity. This is because there's no change in speed. Conversely, if acceleration is negative, the final velocity is less than the initial, indicating a decrease in speed or deceleration.
