Solution:
Consider numbers which are Squares,cubes, fourths, fifths of some natural numbers.
For example, Starting from squares of some natural number: 4,9,16,25,36,49,64......
and their factors , which are 4= 1 × 2×1×2
9=1×3×1×3
16=2×1×2×1×2×1×2×1
25=1×5×1×5
36=2×3×2×3
64=2×4×2×4
Now coming to cubic numbers
8= 1 ×2×1×2×1×2
27= 1×3×1×3×1×3
3125= 3 ×5×3×5×3×5
So,the numbers whose factor pairs repeats are square, cubic, fourth,Fifth ,Sixth and.....higher powers of natural Numbers.
→→→So, we just need to check that whether those numbers whose factor pairs repeats are Squares, cubes or higher powers of natural numbers.
Answer:
Option C
Step-by-step explanation:
we have
Remember that
therefore
Answer:
Step-by-step explanation:
Given
Solving (a): f(a)
Substitute a for x
Solving (b): f(a + h)
Substitute a + h for x
Solving (c):f(a + h) - f(a)h
Substitute values for f(a + h) and f(a)

25123.5325 square feet of tin is needed to make the roof
<em><u>Solution:</u></em>
Given that the roof of a farm silo is the shape of a hemisphere and is made of sheet tin
Given diameter of silo = 126.5 feet
<em><u>To find: sheet tin is needed to make the roof</u></em>
So we have to find the curved surface area of hemisphere
The curved surface area of hemisphere is given as:
Substitute r = 63.25 in above formula
Thus 25123.5325 square feet of tin is needed to make the roof
