We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula
Calculation of area of square:
base=width=8
There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square
so, surface area is .............Answer
Answer:
Graph of the following function is attached with the answer.
Domain : ( - ∞ , + ∞ )
Range : ( 3 , + ∞ )
Step-by-step explanation:
Domain of any quadratic equation is from negative infinity to positive infinity under no restrictions.
So, Domain : ( - ∞ , + ∞ )
The Range of any function can be calculated easily if there is just one term with variable. The method to find Range by that method is explained with the example as follows:
- Range of x : ( - ∞ , + ∞ )
- Range of
: [ 0 , + ∞ ) as every square number is more than or equal to zero.
- Range of
: [ 0 , + ∞ ) as 0/2 = 0 and ∞/2 = ∞.
- Range of
: [ 3 , + ∞ ) as 0 + 3 = 3 and ∞ + 3 = ∞.
Therefore the Range of is [ 3 , + ∞ )
(NOTE <em>: [a,b] means all the numbers between 'a' and 'b' including 'a' and 'b'.</em>
<em>(a,b) means all the numbers between 'a' and 'b' excluding 'a' and 'b'.</em>
<em>(a,b] means all the numbers between 'a' and 'b' including only 'b' not 'a'.</em>
<em>[a,b) means all the numbers between 'a' and 'b' including only 'a' not 'b'.</em>
<em>{a,b} means only 'a' and 'b'.</em>
<em>{a,b] or (a,b} doesn't mean anything.</em> )
