Instructions: Write the explicit rule. Remember to simplify and do not put spaces in your answer. Sequence: 30,0,−30,−60,… 30 ,

Answer:

a(n)=60-30n

Step-by-step explanation:

Equation to use:

a(n) = a(1) + d(n-1)

where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.

In this case, a(1) is 30, d is -30, and n is just n.

If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.

Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.

8 is 15% of what number

Scilla [17]

8 is 15% of what
8 = 0.15x
8 / 0.15 = x

HELP! BRAINLIST COULD GET 50+ POINTS!!!

Answer:

Step-by-step explanation:

well by rotating ΔABC by 60*(degrees) about A , such that in ΔA'B'C,B =C'

you can see that ΔAPP' is equilateral side length 1, meaning that <APP' =60*

you can also see that ΔCPP' is a 30- 60- 90 right angle also meaning that <CPP' =60* now,by adding the two together you see that < ACP =120* now you can also use the law of cosins and soooo

s2=(AP)2+(CP)2-2(AP)(CP)cos120*

s2=1+4-2(1)(2)cos120*

s2=5-4 (-1over2)

s= $\sqrt{x} 5+2\\$

so b is your answer hope this helped
