Which of the following is not an example of exponential growth or decay? a. a t-shirt shrinks by 2% after each wash b. a one time bonus of 10% of a worker’s annual salary c. a yearly pay increase of 3% each year d. a savings account growing by 3% each year

B. A one time bonus of 10% of a worker’s annual salary.

Step-by-step explanation:

In exponential growth or exponential decay, the original size of a quantity is increases or decreases by a constant factor after a particular interval,

Moreover, If change factor > 1 then exponential growth occurs,

If If 1 > change factor > 0 then exponential decay occurs,

In option A,

t-shirt shrinks by 2% after each wash,

Thus, the size of shirt after a wash = 98 % of initial size = 0.98 of initial size,

Hence, the size of shirt is decreases by the factor 0.98 after each wash( particular interval)

Also, 0 < 0.98 < 1

⇒ It is an example of exponential decay,

In option B,

One time bonus of 10% of a worker’s

Since, the bonus will be obtained only one time,

Thus, there is no any growth or decay factor,

⇒ It is not an example of either exponential decay or exponential growth,

In option C,

A yearly pay increase of 3% each year ,

Thus, the pay after 1 year = 103 % of initial pay = 1.3 of initial pay,

Hence, yearly pay increase by the factor 1.3 after each year( particular interval)

Also, 1.3 > 1

⇒ It is an example of exponential growth,

In option D,

A savings account growing by 3% each year,

Thus, the amount after 1 year in the account = 103 % of initial size = 1.03 of initial size,

Hence, the  savings account growing by 3% by the factor 1.03 after each year( particular interval)

Also, 1.3 > 1

⇒ It is an example of exponential Growth.

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
