Answer:
25%
Step-by-step explanation:
price remixed = 300-225=75$
discount % = (75/300)*100 = 25%
Answer:
Step-by-step explanation:
Given equation is,
x² + (p + 1)x = 5 - 2p
x² + (p + 1)x - (5 - 2p) = 0
x² + (p + 1)x + (2p - 5) = 0
Properties for the roots of a quadratic equation,
1). Quadratic equation will have two real roots, discriminant will be greater than zero. [(b² - 4ac) > 0]
2). If the equation has exactly one root, discriminant will be zero [(b² - 4ac) = 0]
3). If equation has imaginary roots, discriminant will be less than zero [(b² - 4ac) < 0].
Discriminant of the given equation = 
For real roots,

p² + 2p + 1 - 8p + 20 > 0
p² - 6p + 21 > 0
For all real values of 'p', given equation will be greater than zero.
Let's set it up like this:

Multiply both sides by



We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:

The variable

can be both positive or negative.

Answer:
6
Step-by-step explanation:
First you know they have <em>50 </em>trees. Then, you know <em>3</em> of <u>25</u> will die.
<u>25</u>*<u>2</u>=<em>50</em>. <em>3</em>*<u>2</u>=6.
Answer: 1.1 Nm
Step-by-step explanation:
The formula for torque is T = r · F · sin θ
where θ = π/6, r = 20 cm = 0.2 m, F = 11 N
formula for converting radians to degrees is 1 rad × 180/π = 57.296°
θ = π/6 · 180/π = 30°
Substituting r into the formula for torque, we have
T = 0.2 x 11 x sin 30° = 0.2 x 11 x 0.5
T = 1.1 Nm
