A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the number of shoppers is 10

Iteru [2.4K]

Answer:

$1,139\ shoppers$

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate in decimal form

b=(1+r)

In this problem we have

x ----> the number of days

y ----> the number of shoppers

a=120

r=10%=10/100=0.10

b=1+0.10=1.10

substitute the values

$y=120(1.10)^{x}$

First day

$y=120$

Second day

For x=1 day

substitute the value of x in the equation and solve for y

$y=120(1.10)^{1}=132$

Third day

For x=2 days

$y=120(1.10)^{2}=145$

Fourth day

For x=3 days

$y=120(1.10)^{3}=160$

Fifth day

For x=4 days

$y=120(1.10)^{4}=176$

Sixth day

For x=5 days

$y=120(1.10)^{5}=193$

Seventh day

For x=6 days

$y=120(1.10)^{6}=213$

Adds the numbers

$120+132+145+160+176+193+213=1,139$

Ccalculate the value of f(4) for this function. f(x) = -(x-7)+3 i know the anwser is f(4)=6 but how?

Tasya [4]

Answer:

See below

Step-by-step explanation:

we have f(x) = -(x-7) + 3

and we want to find f(4)

essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.

So for f(x) = -(x-7) + 3

To find f(4) we replace all x's with 4

f(4) = -(4-7) + 3

we now evaluate

==> subtract 7 from 4

f(4) = -(-3) + 3

==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )

f(4) = 3 + 3

==> add 3 and 3

f(4) = 6
