Answer:

Step-by-step explanation:

The average speed would be 600 km/hr.
Step-by-step explanation:
Let the original speed be 'x'
Let the decreased speed be 'x-200'
Distance = 600 km
Time increased by 30 minutes
According to question, it becomes,

So, The average speed would be 600 km/hr.
It looks like A, but the answer is a little messed up.
The Recursive sequence should be:
An=-1 An+1=An+5
Answer:
Step-by-step explanation:
y= x - 2
the graph would be parallel to y=x and every point would be shifted down 2 units
If you took any point on y = x and represented it as (x,y) then the new point would be (x,y - 2)
Answer:
The height of the lighthouse is approximately 166.6 feet.
Step-by-step explanation:
Let the height of the lighthouse be represented by s, then;
Tan 48° = (opposite) ÷ (adjacent)
Tan 48° = s ÷ 150
⇒ s = 150 × Tan 48°
= 150 × 1.1106
= 166.59
s ≅ 166.6 feet
Therefore, the height of the lighthouse is approximately 166.6 feet.
