28 x 3 3/4 = 84 + 21 = 105 copies.
Answer:
x = 8
y = 3
Step-by-step explanation:
Area = 1/2 √6 (6√2 + √8) Remove the brackets
Area = 1/2 ( 6*√12+ √48)
Area = 1/2 (6*√12 + 4√3) Multiply by 1/2
Area = 3√12 + 2√3
Area = 3*2√3 + 2√3
Area = 6√3 + 2√3
Area = 8√3
the answer is -8. have a nice day!⭐️
A graph of the function is shown below.
The intersections of the equations represent the times when the bird and the ball are at the same height.
8t+20=-16t^2+65t
16t^2-57t+20=0, using the quadratic equation for expediency:
t=(57±√4529)/32 and since we know t>0
t≈3.88 seconds (at a approximate height of 51 feet)
