Answer:
Option D : t = 5s + s/2 is the correct answer.
Step-by-step explanation:
Given that:
t = Combined weight of water and food
s = weight of the snail
Water drank by snail = 5s
Food ate by snail = s/2
Combined weight = Weight of water + Food
t = 5s + s/2
Hence,
Option D : t = 5s + s/2 is the correct answer.
It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.
How many miles will you get with one gallon on a regular road?
How many more miles will you get on a smooth road? 10% more, right? How much is that?
OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.
Answer:
A is 9:1 B is 1:9 C is 5 miles D is 63 minutes

Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
