Hannah has a grid of squares that had 12 rows with 15 squares in each row. She colors 5 rows of 8 squares in the middle of the g

arlik [135]

there's a grid of squares with 12 rows and in each row there are 15 squares

from this grid she colours 8 squares from each row for 5 rows blue.

the rest of the squares she colours red

so first we have to find how many squares are there in the grid in total

so if each row has 15 squares

then 12 rows have - 15 x 12 = 180 squares

blue coloured squares

she colours 8 rows of 5 squares

so if 1 row has - 5 squares

then 8 rows have - 5 x 8 = 40 squares

from 180 squares, she colours 40 squares blue and the rest red colour

therefore the squares she colours red are

red squares = 180 - 40 = 140 squares

she colours 140 squares red

the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation

Arte-miy333 [17]

The exponential equation that models this situation is:

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

$A(t) = A(0)(1 - r)^t$

$A(t) = 18000(1 - 0.15)^t$

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .
