Answer:i need help with same one
Step-by-step explanation:
Answer:
10. (5,-10) and (2,-4)
11. The maximum height of the ball is 16 feet and it occurs 1 second after the ball is kicked.
Step-by-step explanation:
11. f(x)=-16x^2+32x
0=-16x^2+32x
0=x^2-2x
0=x(x-2)
f(x)=-16^2+32x
f(x)=-16 X (1)^2+32 X (1)
= -16+32
=16
X=1
Distribute
2x+2+4=8
Add
2x+6=8
Subtract
2x=2
Divide
X=1
400m = .4 km
so in a day she runs 4000m = 4km
3*4000 = 12000
12000/400 = 30 laps is your answer
Hello from MrBillDoesMath!
Answer:
3/tan(35) (approximately 4.3)
Discussion:
From plane trigonometry
tan (35) = (side opposite angle )/(side adjacent angle)
= 3 / ? (*)
Multiply both sides of (*) by ? to get
? tan(35) = 3/? * ? = 3
Divide both sides by tan(35) to get
? = 3/tan(35)
= 3 /(.700 ) approximately
= 4.3
Thank you,
MrB
