Answer:
<h3>9.9s</h3>
Step-by-step explanation:
First note that the river is on the ground level. The height of the river at the ground level is 0
Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552
When h = 0
0 = -16t^2+1552
16t^2 = 1552
t² = 1552/16
t² = 97
t = √97
<em>t = 9.9secs</em>
<em>Hence the time it takes is 9.9secs to the nearest tenth</em>
(1 + v)(v - 7)
1*(v - 7) + v(v - 7)
1*v - 1*7 + v*v - v*7
v - 7 + v² - 7v
v² - 7v + v - 7
v² - 6v - 7
I hope this helps.
Answer:
The factored equation would be 4x(3y + 7z)
Step-by-step explanation:
In order to find this, look for the greatest common factor and pull it out. Since both have factors of 4 and both have an x, we pull those out. We then divide each term by 4x to get what is left over.
We can have two or more points lying on the same line collinear.
So we can say points lying on same line are collinear but a line cannot be collinear.
