The answer is D. Over 140 Times
The formula for density is Density = mass over volume (D=M/V)

Given two sample sweetener volume put into the same container which is 12oz of carbonated water and each of their density we can compute for the Mass of each and compare.

1.0 Solve Mass of sugar
Given :
Dsugar = 1.6 g/cm³
Vsugar = 25 cm³

Solve :
Msugar = Dsugar x Vsugar = 1.6 x 25 = 40g

2.0  Solve Mass of aspartame
Given :
Daspartame = 1.35 g/cm³
Vaspartame = 0.2 cm³

Solve :
Maspartame = Daspartame x Vaspartame = 1.35 x 0.2 = 0.27g

3.0 How much is the mass difference in diet soda and non diet regular soda
Compare in 12Oz Msugar / Maspartame = 40g/0.27g

Answer : Ratio = 148.148148.. greater.

If f(x) is an exponential function where f(-1.5) 26 and
mariarad [96]

Answer:

f(10) = 1147.25

Step-by-step explanation:

Given

f(-1.5) = 26

f(5.5) = 7

Required

f(10)

An exponential function is represented as:

f(x) = ab^x

f(-1.5) = 26 impleies that:

26 = ab^{-1.5} --- (1)

f(5.5) = 7 implies that

7 = ab^{5.5} --- (2)

Divide (2) by (1)

26/7 = ab^{-1.5}/ab^{5.5}

3.71429 = b^{-1.5+5.5}

3.71429 = b^{4}

Take 4th root

b = 1.39

Substitute b = 1.39 in 26 = ab^{-1.5}

26 = a * 1.39^{-1.5}

26 = a * 0.6102

Solve for (a)

a = 26/0.6102

a = 42.61

f(10) is calculated as:

f(10) = ab^{10}

f(10) = 42.61 * 1.39^{10}

f(10) = 1147.25
