Answer:
383.13
Step-by-step explanation:
Answer:
20.31 units to the nearest hundredth.
Step-by-step explanation:
We need to use the distance formula between the points and find their sum.
D1 = √((2-2^2 + (1+3)^2) = √16 = 4
D2 = √(-1-2)^2 + (3-1)^2) = √13
D3 = √(-3+1)^2 + (0-3)^2) = √13
D4 = √(-3+3)^2 + (-4)^2) = √16 = 4.
D5 = √(-3-2)^2 + (-4+3)^2) = √26.
Perimeter = D1+D2+D3+D4+D5
= 4+√13+√13 + 4 +√26
= 20.31 units.
Lets calculate linear equation
assume
y = f(x)= mx +b
now given
f(0) = 2
m×0+b = 2
b = 2
so b = 2
given f(4) = 0.125 = 1/8
m×4 + 2 = 1/8
4m = 1/8-2= -15/8
m = -15 /(8×4) = -15/32
so linear equation is
y = mx + b = -15x/32 + 2
exponential equation is same as you have written
y = 2(0.5)^x
now put values of x in each equation to get value of y
x =0
linear y = -15×0/32+2 = 2
exp y = 2(0.5)^0 = 2×1 = 2
x =1
linear y = -15×1/32+2 = 2-15/32= 49/32
exp y = 2(0.5)^1 = 2×1/2 = 1
x =2
linear y = -15×2/32+2 = 2-30/32= 17/16
exp y = 2(0.5)^2 = 2×1/4 = 0.5
x =3
linear y = -15×3/32+2 = 2-45/32= 19/32
exp y = 2(0.5)^3 = 2×1/8= 0.25
x =4
linear y = -15×4/32+2 = 2-60/32= 4/32 = 0.125
exp y = 2(0.5)^4= 2×1/16 = 1/8= 0.125
