A A circular oil spill continues to increase in size.
The radius of the oil spill, in miles, is given by the
function r(t) = 0.5 + 2t, where t is the time in hours.
The area of the circular region is given by the
function A(Z) = 172, where r is the radius of the
circle at time t.
Explain how to write a composite function to find
the area of the region at time t.

step-by-step explanation:

no of data

divide by no of mode

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
