The projectile's horizontal and vertical positions at time 
are given by
where 
. Solve 
for the time it takes for the projectile to reach the ground:
In this time, the projectile will have traveled horizontally a distance of
The projectile's horizontal and vertical velocities are given by
At the time the projectile hits the ground, its velocity vector has horizontal component approx. 176.77 m/s and vertical component approx. -178.43 m/s, which corresponds to a speed of about 
.
Let's solve your equation step-by-step.
x2−4x+3=0
Step 1: Factor left side of equation.
(x−1)(x−3)=0
Step 2: Set factors equal to 0.
x-1=0 or x-3=0
For this one add one on both sides
x−1+1=0+1 x=1
For this one add 3 on both sides
x−3+3=0+3. x=3
x=1 or x=3
Answer:
x=8
Step-by-step explanation:
Those angles are supplementary so:
140+5x=180
5x=40
x=8
76,500,000 in scientific notation is: 7.65x10^7
I believe you moved the decimal to the right 2 times.
Hope this helped :)
Have a great day
