A) 500 + 4(.06*500)
B) 
Answer:
The two numbers following 1,-2,3,-4,5... are -6 and 7.
Step-by-step explanation:
index: 1 2 3 4 5 ....
value: 1 -2 3 -4 5
Let the index be n. Then the first term is a(1), the secon is a(2), and so on.
a(2) = 2*(-1)^(2-1) = 2*(-1) = -2 (correct)
a(3) = 3*(-1)^(3-1) = 3*(-1)^2 = 3 (correct)
a(4) = 4*(-1)^(4-1) = 4*(-1)^3 = -4 (correct)
So the general formula for a(n) is: a(n)=n(-1)^(n-1)
Thus,
a(5) = 5(-1)^4 = 5
a(6) = 6(-1)^5 = -6
a(7) = 7(-1)^6 = 7
The "next two numbers in the pattern" are -6 and 7. The first 7 numbers are
1,-2,3,-4,5, -6, 7
Answer:
3. 2/3
Step-by-step explanation:
y=tan(2arctan(1/3))
= 2tan(arctan(1/3))
= 2*1/3
= 2/3
Answer:
C. 129
Step-by-step explanation:
In the parallelogram, opposite angles are equal
So
<KJO = <KLM
but
<KLM = <KLO + <MLO = 68 + 61 = 129
so
<KJO = <KLM = 129
Answer
C. 129
