Answer:
4/7x - 5 ________________________________________
Answer:
sin(4π/21)
Step-by-step explanation:
Step 1: Rearrange expression
sin(π/3)cos(π/7) - cos(π/3)sin(π/7)
Step 2: Use sin(A ± B)
sin(π/3 - π/7)
Step 3: Evaluate
sin(4π/21)
And we have our answer!
Step-by-step explanation:
Given
mass (m) = 5000 kg
velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s
Now
Kinetic energy
= 1/2 mv²
= 1/2 * 5000 * 27.78²
= 1929321 joule
Let
x--------> the length side of the original square paper
we know that
<u>the area of the original square paper is equal to</u>

<u>the area of the remaining piece of paper is equal to</u>

therefore
<u>the answer is the option </u>
x2 − 2x − 120 = 0
I am only guessing that you mean:
(n-2)/-3<7 if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)
n-2>-21 add 2 to both sides
n>-19
