8. (-2,-1)
10. y≥2
Step-by-step explanation:
7. a|x-h|+k
Vertical stretch by a factor of two, horizontal shift left two, vertical shift down one
8. (h,k)
10. It should be y, but otherwise you are good
Answer:
Philadelphia to Gettysburg.
Step-by-step explanation:
For Allentown to Gettysburg, the drive is
1hour= 55m
1m = hour
= 0.018 hour
For Philadelphia to Gettysburg, the drive is
1 hour = 65m
1m = hour
= 0.015 hour
For Reading to Gettysburg, he drive is
1 hour= 40m
1 m = hour
= 0.025 hour
Therefore, Philadelphia to Gettysburg has shorter drive in hours that is 1 metre is travelled in 0.015 hours
To solve this problem, we will need the standard kinematics equation
where
v0=initial velocity (positive upwards) m/s
t=time in seconds
a=acceleration due to gravity (positive upwards) = -9.81 m/ ²
Substituting values,
distance = 0 (when it falls back on earth)
v0=42 m/s
a=-9.81 (negative means towards earth, downwards)
factor and solve
=>
t=0 (beginning of launch), or
42-(1/2)*9.81t=0 => t=2*42/9.81=8.563 s.
Time to return = 8.6 seconds (to the nearest tenth of a second)
Answer:

Step-by-step explanation:cghctf
5 1/4 gallons of paint, because 3+1=4 and 1/2=2/4. 2/4+3/4=5/4 which is an improper fraction, so you have to make a whole. 5/4=1 1/4. So 4+1 1/4=5 1/4
