Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as
then the equation relating them is
w =
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w
= 4 ×
= 4 × 2 = 8
w =
← equation of variation
When x = 25, then
w =
=
= 1.6
Answer:
1/3
Step-by-step explanation:
-6+(-1/3)= -19/3
-19/3 + 20/3 = 1/3
Substract 6 to both sides and you get 36 =-2d then you use the multiplicative inverse and d=-18.
A1 = 0.91
a6 = -0.14
sum = (0.91+-0.14) /2
sum = 2.31
