What the general equation of a sine function with an amplitude of 6, a period of pi/4, and a horizontal shift of pi/2?

answer:

4

step-by-step explanation:

answer:

definitions:

the third quartile, denoted by q3 , is the median of the upper half of the data set. this means that about 75% of the numbers in the data set lie below q3 and about 25% lie above q3;

the upper half of a data set is the set of all values that are to the right of the median value when the data has been put into increasing order;

first, we verify data in increasing order:

21, 24, 25, 28, 29, 35, 37, 38, 42 ( okay);

the median is 29;

therefore, the upper half of the data is {35, 37, 39, 42};

q3 = ( 37 + 39 ) / 2 = 76 / 2 = 38;

step-by-step explanation:

answer:

thus, the two root of the given quadratic equation     is 2 and -3 .

step-by-step explanation:

consider, the given quadratic equation,

this can be written as ,  

we have to solve using quadratic formula,

for a given quadratic equation we can find roots using,

  )

where,   is the discriminant.

here, a = 1 , b = 1 , c = -6

substitute in (1) , we get,

and

and

and

thus, the two root of the given quadratic equation is 2 and -3 .
