(1)
The square root of 8 is somewhere between 2 and 3, because
So, 
is between -1 and 0, whereas 
is between 2 and 3.
So, we have
(2)
The square root of 25 is 5, because 
So, the left hand side is exactly
You seem to have already computed the right hand side to be 2.30, so we have
Answer:
i.) 66% of the earth is covered in water
ii.) 33% is continental
Step-by-step explanation:
Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A
Answer:
9
Step-by-step explanation:
Here,
f(1) = 1,
f(n) = 3f(n-1),
f(4)= 3×1(4-1)
= 3×3
=9
