Answer:
x=2 and y= 4
Step-by-step explanation:
y = x +2 ----------(i)
y = 3x -2--------(ii)
Now, comparing (i) and (ii)
x+2= 3x-2
=>x-3x = -2-2
=>-2x= -4
=>2x= 4
=>x= 2
From eq (i)
y= x+2 = 2+2= 4
Let h(t) represent the height of the projectile after t seconds. If the projectile is being launched from the ground, then h(0)=0, and h(t)=-4.9t²+98t. When the equation is in this form, the maximum height is determined by -98/2(-4.9), or after 10 seconds. Thus
-4.9(100)+98(10)=490 m as the highest point of the projectile
Then, when it hits the ground, h(t)=0, so
0=-4.9t²+98t
98t=4.9t²
4.9t=98
t=20

<em>Coplanar</em> means "lying on the same plane," while <em>colinear </em>means "lying on the same line." In this problem, all four points A, B, C, and D are coplanar - they all lie on the plane 
- so we just need to find the points that lie on the same line. Though points C and B <em>would </em>be colinear if there was a line drawn between them, there's no such line in this problem, so we can rule that out. We notice one line drawn on the plane, and points A, C, and D lying on it, so we can say that points A, C, and D are both coplanar and colinear.
Answer: 45 ft
Step-by-step explanation:
and 15ft add 10ft to get 25ft
then subtract 70 from 25
