Marissa bought a car for $22,000. The value of the car is decreasing at a rate of 10.5% every year. After 5 years, the value of
torisob [31]

Answer: the value of the car will be about $12634

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r)^ t

Where

A represents the value of the car after t years.

t represents the number of years.

P represents the initial value of the car.

r represents rate of decay.

From the information given,

P = $22000

r = 10.5% = 10.5/100 = 0.105

t = 5 years

Therefore

A = 22000(1 - 0.105)^5

A = 22000(0.895)^5

A = $12634

A professor is examining a new strain of bacteria. The amount of bacteria can be modeled by function s(n) = 20 · bn, where n is
user100 [1]
For this case we have a function of the form:
 y = A * (b) ^ n&#10;
 Where,
 A: initial amount
 b: growth rate (if b> 1)
 n: time in hours
 Substituting values we have:
 s (n) = 20 * b ^ n&#10;
 We have then that the initial amount is:
 A = 20&#10;
 If b = 1.85 then the growth percentage is:
 (1.85-1) * (100) = 85%&#10;
 Answer:
 
here were initially 20 bacteria.
 
The hourly percent growth rate of the bacteria would be 85%

Here is the histogram of a data distribution. All class widths are 1. What is the median of this distribution?
Bingel [31]

Answer:

The median is 4.

Step-by-step explanation

if you layout all the number, you get

1,2,2,3,3,3,4,5,5,5,6,6,7

So, to find the median you find the number(s) right in the middle.

(Ex. 3,4,5; 4 is the median)

(Ex. 3,4,5,7; 4.5 is the answer)

The middle number of

1,2,2,3,3,3,4,5,5,5,6,6,7

is 4, so 4 is the median.

hope this helps. :)

What is the area of parallelogram RSTU? 21 square units 24 square units 28 square units 32 square units
Debora [2.8K]

Answer: 21 square units

Step-by-step explanation:

We know that the area of parallelogram is given by:-

A=height\times base

Let US denote the height of the Parallelogram RSTU with corresponding base ST.

By counting the distance between the points using grids or by distance formula,

US=|4-(-3)|=|7|=7\ units

ST=|-1-(-4)|=|-1+4|=|3|=3\ units

Now, the area of parallelogram RSTU is given by:-

A=7\times3=21\ \text{square units}
