Flu has spread in school such that after x days, the number of sick students f(x) is given by f(x)=15x-x² where 0<or equal to x <or equal to 15. a. at what rate had flu spread after first day

b. when the flu has spread at the rate of 3 students per day, how many students where sick.

c. what is the value of x when f'(x)=0? Find the value of spread at this value of x interpret the value

d. what happens atfer the 10^th day

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

step-by-step explanation:

hjkj

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
