Answer:
y=5/2x
Step-by-step explanation:
The line needs to go through the points (0,0) and (2,5).
With y=5/2x, there is no y-intercept, so it starts on the origin, (0,0). With the slope 5/2, you would rise 5 (y) from the origin, and run 2 (x), which gives you the point (2,5).
H=+15 m
v=+5 m/s
Ball hits the ground when h(t)=-15m
h(t)=-9.8t^2+vt+h
=>
-15=-9.8t^2+5t+15
9.8t^2-5t-30=0
Solve for t, using quadratic formula,
t=-1.513 or t=2.023
reject negative root due to context, so
t=2.023 seconds
2)
h(t)=-16t^2+20t+8
a. height before pitch is when t=0, or h(0)=8
b. highest point reached when h'(t)=-32t+20=0 => t=5/8 seconds
c. highest point is t(5/8)=-16(5/8)^2+20(5/8)+8=47/5=9.4 m
d. ball hits ground when h(t)=0 => solve t for h(t)=0
=> t=-0.3187 seconds or t=1.569 seconds.
Reject negative root to give
time to hit ground = 1.569 since ball was pitched.
Interest = PRT/100
I= 14000*0.12*3
I=5040
Add Interest to the Principal
14000 + 5040
= $19,040
A is the answer.
Answer:
x= 2-1/2
Step-by-step explanation:
14x + 7y = 28
SUBTRACT 7Y FROM BOTH SIDES (TO ISOLATE X)
14x=28-7y
DIVIDE BY 14 TO ISOLATE X
x= 2-1/2

From the table we notice that:
This means that Diana traveled 11595 ft more than martin; this also means that Jake and Abby traveled more than that amount farther than Martin's balloon (since their distances are greater that Diana's distance)
Therefore, Abby's Jake's and Diana's balloons traveled 11595 ft farther than Martin's balloons.
