Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track :
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters
Answer: Choice B
======================================================
Explanation:
The original equation is with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.
The general rule is that is equivalent to the log form of
where b is the base of each.
Answer:
The coordinates of point D( 4,4)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are E(10,4) and B(16,4)
'E' is the mid-point of segment BD
Let D(x₁, y₁) be a point
E = midpoint of segment BD
20 = x₁ + 16
20-16 = x₁
x₁ =4
<u><em>Step(ii):-</em></u>
4 + y₂ = 8
y₂ = 8-4 =4
The co-ordinates of point D( 4,4)
