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.
Answer:
32
Step-by-step explanation:
The facts we have are the height of the small lighthouse is 8, and the base is 2.5. The base of the big lighthouse is 10.
The factor between the base of the big lighthouse and small lighthouse is 4 (10/2.5).
If we apply this to the height, 8x4 = 32
Answer:
18x - 12
Step-by-step explanation:
multiply each term in the parenthesis by the 6 outside ( distributive law)
6(3x - 2)
= (6 × 3x ) + (6 × - 2) = 18x +(- 12) = 18x - 12
3/4=0.75 or 75%
1/2=0.5 or 50%
So, 3/4 is bigger.
Answer:
0
Step-by-step explanation:
Put -6 where x is and do the arithmetic.
f(-6) = 1/3 (-6 +6) = 1/3 (0)
f(-6) = 0
