Answer: z=22
Explanation:
9^2 + z = 103
81 + z = 103
103 - 81 = z
22 = z

Answer:
Step-by-step explanation:
Give the DE
dy/dx = 1-y
Using variable separable method
dy = (1-y)dx
dx = dy/(1-y)
Integrate both sides
∫dx = ∫dy/(1-y)
∫dy/(1-y)= ∫dx
-ln(1-y) = x+C
ln(1-y)^-1 = x+C
Apply e to both sides
e^ln(1-y)^-1 = e^,(x+C)
(1-y)^-1 = Ce^x
1/(1-y) = Ce^x
Step-by-step explanation:
7x-1=8x-14
-1+14=8x-7x
13=x
Answer:
The dog is 20 inches tall now.
Step-by-step explanation:
Given that:
Height of dog when it was a puppy = 
inches
Height of dos now = 
than previous height
It means that we will add this height in the height of dog when it was a puppy.
Height of dog now = 
Height of dog = 
Height of dog = 20 inches
Hence,
The dog is 20 inches tall now.
