4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h
Slop=(y2-y1)/(x2-x1)
Slop=(-6-(-4))/(7-4)
Slop=-2/3
Answer:
Step-by-step explanation:
1) 
= 50 + (-9*8) *1
= 50 - 9.8
= 40.2 m/s
2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²
3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.
<span>First we will find all factors under the square root: 147 has the square factor of 49.Let's check this width √49*3=√147. As you can see the radicals are not in their simplest form.Now extract and take out the square root √49 * √3. Root of √49=7 which results into 7√3<span>All radicals are now simplified. The radicand no longer has any square factors.
the answer is </span></span><span>7√3
