Exponential Growth Problem f(1) = a(1 + r)
a = initial amount
r=rate of increase (growth rate)
t = time
f(t)=final amount
The prize for a radio station contest begins with a $100 gift card. Once a day, a name is
announced. The person has 15 minutes to call or the prize increases by 2.5% for the next
day.
(Hint: the 15 minutes is just extra information and wouldn't be included in the problem)
The amount of money starts with | Select]
and this is the starting or initial
amount in the equation. I need to change the percent to a decimal in order to find the rate,
which is Select

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
