Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88

<u>Newton's Law of Motions</u>
- Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
- Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
- Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u>

<h3>
Step-by-step explanation:</h3>
<u>Step 1: Define</u>
[Given] F = 20.0 N
[Given] a = 5.0 m/s²
[Solve] Mass <em>m</em>
<em />
<u>Step 2: Solve for </u><em><u>m</u></em>
- Substitute in variables [Newton's 2nd Law of Motion]: 20.0 N = m(5.0 m/s²)
- [Division Property of Equality] Divide 5.0 on both sides: 4.00 kg = m
- Rewrite: m = 4.00 kg
Answer:
<h2>26 Shilling</h2>
Step-by-step explanation:
The amount to be paid = The new price
where;
New price = (100-x)/100 * Original price
Original price = 40.00
x = discount
<h2>Placing in formula</h2>
100-35/100 * 40.00
65/100 *40
26 shilling
<h2>Therefore the amount you will pay for the discount is 26 shilling</h2>
