Answer:
A HCF is the highest common factor between 2 or more numbers. because every number times 1 is equal to itself, every 2 numbers have a common factor of 1.
HCF between 2 numbers a,b or expressions such that a and b are not equal to 0 , will never be 0 , because of the simple fact that anything times 0 is equal to 0 , and we stated that a,b isn’t equal to 0 , so that’s a contradiction.
Since you stated that there is no common factor bigger or lower than 1 between the 2 numbers (which means that the two numbers are equal to each other and equal to 1 or 0 , think about it yourself a little bit) that means that the only factor is 1 when the two numbers are not 1 , and 0 or anything if the two numbers are 0 , because again, every number times 0 is equal to 0 .
So finally, there is not HCF if the two numbers stated are both 0 , and the only other possibility is for them to be 1 , and in this case, the HCF will be 1 .

Answer:
The distance travelled by the kite is 122.8 ft ( approx )
Step-by-step explanation:
Here, the given function,
Differentiating with respect to x,
∵ arc length of a curve is,
Where, y shows the height of the curve for a ≤ x ≤ b,
Thus, the arc length of the given curve is,
Put 
By integration by parts,
If x = 80, 
Thus, the length of the curve is,
Answer:
Step-by-step explanation:
As given ,
-5*(a+3) =-55
(-5*a)+(-5*3)= -55
-5a-15= -55
-5a= -55 +15
-5a = -40
a = 8
