The <em>correct answers</em> are:
C) a(n) = 0.3+(n-1)0.6
; and
C) a(n) = 47+ (n-1)(-15)
Explanation:
#1) This is an arithmetic sequence, since we are adding the same value to each term to find the next term. We add 0.6 each time, so this is the common difference. The first term is 0.3. This goes in the formula
#2) This is also an arithmetic sequence. This time, we add -15. The first term of this one is 47. This gives us:
Step-by-step explanation:
diameter (d) = 7cm
radius (r)= d/2 .... formula
= 7/2 .....put the value
= 3.5cm
the measure of radius is 3.5cm.
Answer:The answe is 2 because ther are only 2 skirts
Step-by-step explanation:
Answer:
The correct answer is option B.
Step-by-step explanation:
The given rational expression is:
Factor the numerator and the denominator:
Factor the numerator using difference of two squares and the denominator using factorization by grouping.
This function is defined if and only if the denominator is not zero.
That is: (x+3)(x+2)≠0.
x≠-2,x≠-3
We simplify now to obtain:
The correct choice is the second option.
