Answer: 511
Step-by-step explanation:
53.
For this problem simply plug in the numbers: 1 through 9 for n
the n=1 on the bottom represents the start and the 9 at the top represents the end
and the 2^n-1 represents the rule
solving for a1: plugging in one for n
a1=2^1-1
a1=1
a2=2^2-1
a2=2
a3=2^3-1
a3=4
a4=2^4-1
a4=8
a5=2^5-1
a5=16
a6=2^6-1
a6=32
a7=2^7-1
a7=64
a8=2^8-1
a8=128
a9=2^9-1
a9=256
after finding all these values add them all together and you should get your answer
1+2+4+8+16+32+64+128+256
=511
Answer:
f(x)=-2(x+6)-12
Step-by-step explanation:
so the easiest one to do would be vertex form
f(x)=a(x-h)+k
so your vertex represents (h, k)
so plug in those values
f(x)=a(x- - 6) -12
now use the other point to solve for a
-24=a(0+6)+12
-24=6a+12
-12=6a
-2=a

Answer:
(15+3d)/6 = c
2 1/2 + 1/2d = c (more simplified)
Step-by-step explanation:
15 = -3(2c +d)
15 = -6c -3d
+3d +3d
15 +3d = -6c
/-6 /-6
(15+3d)/6 = c
2 1/2 + 1/2d = c
