Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2
T = 7.41 seconds

Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle = 
, where p is half the perimeter of the triangle
p = 
units
Area = 
= 62.1467 square units (correct to four decimal places)
Answer:
Answer will be 28
Step-by-step explanation:
We have to find the GCF( LCM(8,14) , LCM (7,12) )
Here GCF is stands for greatest common factor and LCM is stands for lowest common factor
Let first find LCM of (8,14)
8 = 2×2×2
14 = 2×7
So LCM will be 2×2×2××7 = 56
Now LCM of (7,12)
7 = 7×1
12 = 2×2×3
So LCM will be 2×2×3×7 = 84
Now GCF of (56,84)
56 = 2×2×2×7
84=2×2×3×7
So GCF will be 2×2×7 = 28
