Answer:
600 ft in one minute
i don't know if my answer is correct or not
Step-by-step explanation:
Object 1 280 ft/min => 85 m/min => 85/60 m/sec
sim.
Object 2320 ft/min => 98 m/min => 98/60 m/sec
when two bodies move in opp. direction there speeds are added
so
resultant speed is object 1 + object 2
the resultant comes out as 183/60 m/sec
time is given 1 minute
and we know Distance = time * speed
distance = 183/60 * 60 (183/60 is the speed and 60 is the time in sec as 1 min. = 60sec)
so the distance comes out as 183 m
convert it into ft
1m = 3.2 ft
so 600 ft in one minute
Answer:
a = - ![\frac{13}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B16%7D)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = - ![\frac{13}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B16%7D)
(732,837329).............
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
![\frac{-13}{-3z}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-13%7D%7B-3z%7D%20)
(divided both sides by -3z)
z=
