Manny Brought a brand new car in 2012 for $28750. if the car depreciates by 12% each year, write n exponential function to model
alexira [117]
The formula for exponential decay is 
y=a(1-r)^{x}

where  a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 .  2018-2012 = 6 years)

y=28750(1-0.12)^{6}

1) The astronaut's sense of imbalance in a space flight is due to the rotation of a device in which he or she feels a fictitious
max2010maxim [7]

Answer:

n = 0.38 rotation per second

Step-by-step explanation:

The device rotates according to the mathematical equation :

n=\dfrac{g^{0.5}}{2\pi r^{0.5}} ...(1)

Where n is the rotational speed and is measured in rotations per second (s).

r is radius of the circulator and is measured in meters (m).

We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).

n=\dfrac{(9.8)^{0.5}}{2\pi \times (1.7)^{0.5}}\\\\=0.38\ \text{rotations per second}

Hence, the rotational speed is 0.38 rotation per second.

The plot below shows the volume of paint left in 444 cans.
yKpoI14uk [10]

The amount of paint that would be contained in each of the can would be 8.

<h3>How to solve for the amount of paint.</h3>

Using the information in the question we have the following

We have to solve the equation as

(2  1/2)   + 2(4)  + 1(5  1/2)  =

2.5 + 8 + 5.5

= 16

Each of these would have to hold 16/2 = 8 pints.

This question is hard and I don’t know it may u please help
zloy xaker [14]

Answer:

Mark's total salary is 22,260

Step-by-step explanation:

well, his base salary is 21,000.

if you look at the diagram, the added bonus is 6% of the base salary.

6% can be rewritten as 0.06

0.06 * 21,000 = 1,260

the total salary is just the base salary and the bonus salary added together.

21,000 + 1,260 = 22,260
