Answer:
R = 1.2%
Step-by-step explanation:
<u>Given the following data;</u>
Principal = 425
Time = 2
Simple interest = 10.20
To find the annual interest rate;
Mathematically, simple interest is calculated using this formula;
Where;
- S.I is simple interest.
- P is the principal.
- R is the interest rate.
- T is the time.
Substituting into the equation, we have;
Cross-multiplying, we have;
<em>R = 1.2%</em>
<em>Therefore, the annual interest rate is 1.2 percent. </em>
You can write the equations of motion as
h(t) = -16t² + v₀sin(θ)t
d(t) = v₀cos(θ)t
Solving the second of these for t and substituting into the first equation gives the time of flight as
0 = -16t² + d(t)·tan(θ)
t = √(d(t)·tan(θ)/16)
So, for d(t) = 400 and θ = π/6, this becomes
t = √((400/16)/√3)
t = 5/√(√3) ≈ 3.79918
The ball is in the air about 3.80 seconds.
All right angle triangles have a 90 degree angle. 90+42=132
All triangles have angles that add up to 180 degrees 180-132=48
90+42=132
180-132=48

#1: 4*5 + 4*6=20+24=44
#2: 4*(5+6)=4*11=44
