Answer:
The ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.
Step-by-step explanation:
The quadratic function
represents the height of the ball above the ground, h(t), in meters, with respect to time, t, in seconds.
To find h(3), substitute t = 3 into the function expression:

Meaning: the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.
It would be 5850 hope you get it right:)
Answer:
x = 20
Step-by-step explanation:
2x + 7x = 180
⇔ 9x = 180
⇔ x = 180/9 = 20
Answer:
680
Step-by-step explanation:
x = total number
.6x = bus riders = 408 (.6 is decimal for 60%)
.6x = 408
x = 408/.6 = 680
Answer:
Start with y=mx+b since it is perpindicular to the slope of -3/4 the new slope is 3/4. so now we have m=4/3 next we subsitute known values in (0,-1). We multiply 0 by 3 next we have -1=0+b so be has to be -1 so your awnser is
y=4/3-1
