State whether the decay is linear or exponential, and answer the associated question. The value of a car is decreasing by 9% p

Sunny_sXe [5.5K]

Answer:

Exponential
A(2)=$9109.10

Step-by-step explanation:

Since the value of the car decreases by a common factor each year, the decay is exponential.

An exponential decay function is of the form

$A(t)=A_0(1-r)^t$ where:\\Initial Value, A_0=\$11,000\\$Decay Factor, r=9%=0.09$

Therefore, the function modeling the car's decay is:

$A(t)=11000(1-0.09)^t$

We want to determine the car's value in two years.

When t=2

$A(2)=11000(1-0.09)^2\\A(2)=\$9109.10$

The value of the car in 2 years will be A(t)=$9109.10

At a local college, of the male students are smokers and are non-smokers. Of the female students, are smokers and are non-smoker

natima [27]

Answer: Our required probability is 0.88.

Step-by-step explanation:

Since we have given that

Number of male students are smokers = 10

Number of male students are non smokers = 490

total number of male students = 500

Number of female students are smokers = 40

Number of female students are non smokers = 363

Total number of female students = 403

Probability that both are non smokers is given by

$P(Non-smoker\ male)\times P(Non-smoker\ female)\\\\=\dfrac{490}{500}\times \dfrac{363}{403}\\\\=0.98\times 0.9\\\\=0.88$

Hence, our required probability is 0.88.

Determine the intercepts of the line: -3x-4=-5y-8

Nina [5.8K]

The x-intercept is 4/3 and y-intercept is -4/5

Step-by-step explanation:

Given equation of line is:

$-3x-4=-5y-8$

To find the x-intercept, we put y=0 in the equation

$-3x-4=-5(0)-8\\-3x-4=0-8\\-3x-4=-8\\-3x=-8+4\\-3x=-4$

Dividing both sides by -3

$\frac{-3x}{3} = \frac{-4}{-3}\\x = \frac{4}{3}$

To find the y intercept, we put x=0

$-3(0)-4=-5y-8\\-4 = -5y-8\\-5y-8 = -4\\-5y = -4+8\\-5y = 4\\$

Dividing both sides by -5

$\frac{-5y}{-5} = \frac{4}{-5}\\y = -\frac{4}{5}$

Hence,

The x-intercept is 4/3 and y-intercept is -4/5

For a car renting for $26.00 per day and $.15 per mile Find how many miles were driven if the bill was $41.30. Write the functio

AleksAgata [21]

The function that you would use would be 26 + 0.15x = 41.30.
