39. * short response you make and sell flags for $10 each. each flag
requires $4.50 worth of fabric. you pay $12.99 for a kit to punch holes to
hang the flags. your expenses (in dollars) are given by the expression
4.50m + 12.99 where m is the number of flags you make. your income is
given by the expression 10s where s is the number of flags you sell. your
profit is equal to the difference of your income and your expenses.
a. you make 50 flags and sell 38 of them. find your income and your
expenses. then find your profit.
b. explain how you could use a single expression to determine
your profit.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
