Answer:
Option B. 44 is the correct answer
Step-by-step explanation:
Let l be the number of large pizzas and s be the number of small pizzas
Then according to the given statement the equations will be:
From equation 1
Putting in equation 2
Putting s=72 in equation 1
How many more small pizzas means we have to find s-l
So,
s-l = 72-28 = 44
Hence,
Option B. 44 is the correct answer
Answer:
x = ±2, 3 are the critical points of the given inequality.
Step-by-step explanation:
The given inequality is
To find the critical points we will equate the numerator and denominator of the inequality to zero.
For numerator,
(x - 2)(x + 2) = 0
x = ±2
For denominator,
x² - 5x + 6 = 0
x² - 3x -2x + 6 = 0
x(x - 3) -2(x - 3) = 0
(x - 3)(x - 2) = 0
x = 2, 3
Therefore, critical points of the inequality are x = ±2, 3 where the sign of the inequality will change.
The components are Nx= Ncosθ and Ny= -Nsinθ
<h3>What is a Vector?</h3>We know that the vector quantities are those quantities that have magnitude as well as direction.
Each vector quantity can be divided into two parts a horizontal and vertical component, the vertical component is known as the sine component while the horizontal component is known as the cosine component.
A vector component is the product of its length and the component angle.
Generally, F sinθ is the vertical component and F cosθ is the horizontal component,
Now, from the diagram the horizontal component of vector 'r' is
Nx= Ncosθ
and, the vertical component will be
Ny= -Nsinθ
this is in the opposite direction
