Answer:
2
Step-by-step explanation:
Slope = (6 - 4)/(2 - 1)
Slope = 2/1 = 2
Hours is2,3,4,5 .and the quarts is 5,6.5,8,9.5 .what is the equation of the these relationship
Answer:
1
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (-2-2)/(-2 -2)
=-4/-4
=1
Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.
