Find Length of the square :
------------------------------------------------------------
Given that the area of the square is 32 cm²:
Area = Length²
------------------------------------------------------------
Find Radius :

The Answer is 11.5 because 3•-8=-24+5=-19-4=-23%2 gives you 11.5
Odd numbers are of the form:
2n-1
So first we need to know how many odd numbers there are between 100 and 200...
100<2n-1<200 add 1 to all terms
101<2n<201 divide all terms by 2
50.5<n<100.5, since n must be an integer
51≤n≤100 so there are 100-51+1=50 odd numbers
Notice that 2n-1 forms an arithmetic sequence from 101 to 199 in this instance.
The sum of any arithmetic sequence is the average of the first and last terms times the number of terms, mathematically:
s=(a+b)(n/2), where a and b are the first and last terms and n is the number of terms, we saw earlier that there are 50 terms and that a=101 and b=199 so:
s=(101+199)(50/2)
s=7500
So the sum of all odd numbers between 100 and 200 is 7500.
Answer:
Option C
Step-by-step explanation:
The domain is the input values of the function for which the function has values. Since the operations in the function are radicals, the inside of the radicals must be greater than 0 otherwise imaginary numbers will result. The denominator also cannot equal 0 because dividing by 0 does not exist. To find these, we set the inside of the radicals equal to 0.
x+2=0
x=-2
x=7=0
x=7
The domain is between -2 and 7. . It can be equal to 7 as well as less than 7.
