Answer:
2 seconds and 38 seconds
Step-by-step explanation:
h=-16t²-vot
1,200=-16t²-640t
turn this into standard form
16t²-640t+1200=0
now plug thes numbers into the quadratice formula
a 16 b -640 c 1200
solve with quadratic formula to get ≅2 and ≅38 seconds
Answer:
diameter-- last picture on right side
radius-second last picture on right side
πd=2πr
2r=d/2
Step-by-step explanation:
diameter is a line segment that goes through the center of a circle
this will match to the last image on the right side
radius is half of the diameter or from a point on the outer edge of the circle to the center
this will match to the second one on the right side
πd-- d=2*radius
2πr
2r=d/2
because radius is half of the diameter

Y= 3(3)–2(3)2+5(3)3
y= 9–2*3*2+5*9
y=9–12+5*9
y=9–12+45
y=42
