Answer:
5 secs
Step-by-step explanation:
The height of the object is given as:
The moment when the object hits the ground, the height of the object will be 0 m.
Hence:
Solving this for t:
Divide through by 16 and move all parameters to the left hand side:
Since time cannot be negative, time, t = 5 secs.
The object will hit the ground after 5 secs.
Over 140 times bigger because 25 cm³ of sugar is 40 grams (25×1.6)
and .2 cm³ of aspartame is 0.27 grams (0.2×1.35)
and 40 is 148 times as big as 0.27 (0.27×148.1481481≈40)
Answer:
33.3%
Step-by-step explanation:
If all of them are equal out of 100%
that means Roses are 33.3 daffodils are 33.3 and lilly's are 33.3
The area, which is L x W.
L = x+14
W = x-20
Therefore, LW or (x+14)(x-20) is the area
Answer:
k = - 1
Step-by-step explanation:
If (x - 5) is a factor of p(x) then p(5) = 0
p(5) = 5³ - 6(5)² + 5k + 30 = 0 , that is
125 - 150 + 5k + 30 = 0
5 + 5k = 0 ( subtract 5 from both sides )
5k = - 5 ( divide both sides by 5 )
k = - 1
