Answer:
Mia was faster
Step-by-step explanation:
Mia traveled at 2.5 meters per second whereas Oriya traveled at 2.2 meters per second
G(x) = 20(1.5)^x
Using the graph we can figure out that:
f(x) = 15(2)^x
So does f(x) have a faster rate of change than g(x) on the interval (-5,-3). I used the rate of change formula, and saw that it does NOT.
f(x) and g(x) are always positive, so the second one is not true.
f(x) and g(x) are always increasing, so the third one is TRUE.
g(x) intercept is 20 and f(x) intercept is 15, so the fourth one is TRUE.
So the answer is C and D.
Answer: Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.
Step-by-step explanation:
Terry is buying water and needs 22 liters. A half-liter of water costs $2.11. Using this information, 22 litres will cost:
= 22 ÷ 1/2 × 2.11
= 22 × 2 × 2.11
= $92.84
Also, A 200 -milliliter container of water costs $1.01. Using this information, 22 litres will cost:
= 22 × 1.01 ÷ 200/1000
= 22 × 1.01 × 1000/200
= 22 × 1.01 × 5
= $111.1
Based on this information, Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.
