The first thing you must do to find the normal force is to know that it is always perpendicular to the surface.
The weight always points down.
Making a free body diagram in vertical direction we have that the normal force is:
N = m * g * cosθ
answer:
the normal force is:
N = m * g * cosθ
The comparison of the lengths of the sides based on the angles are given
by sine rule.
The lengths of the sides from greatest to least are;
Reasons:
The given parameters are;
∠A = 78°, ∠B = 56°, ∠C = 46°
By sine rule, we have;
Given that, sin(46°) ≈ 0.719, sin(56°) ≈ 0.829, sin(78°) ≈ 0.978, we have;
sin(78°) > sin(56°) > sin(46°)
Therefore, applying equal proportions of similar ratios, we have;
<u>BC > AC > AB</u>

Answer:
first three expressions are polynomials and last three are not.
Step-by-step explanation:
last three expression has negative powers of X and some powers of Xs are not integers.
Answer: P(10,15,0.7)=3003*0.7^10*0.3^5=approx 0.2061
Step-by-step explanation:
The required probability P(10,15,0.7)= C15 10 *p^10*q^(15-10) where
C15 10= 15 !/10!/5!= 11*12*13*14*15/(2*3*4*5)=11*12*13*14/(2*4)=11*3*13*7=
=77*39=3003
p=0.7 q=1-p =1-0.7= 0.3 (probability of not having vcrs)
So P(10,15,0.7)=3003*0.7^10*0.3^5=approx 0.2061
