Patty is a member of the environmental club. each weekday, she volunteers for 2 hours. on saturday and sunday, she volunteers 3 hours more each day. which expression shows how to find the number of hours she volunteers in one week

20

Step-by-step explanation:

She volunteers for hours on each week day = 2

No. of week days = 5

So, She volunteers for hours on 5 week day =

On Saturday and Sunday, she volunteers 3 hours more each day.

So, on weekend She volunteers for hours on each day = 2+3 = 5 hours

No. of days in weekend = 2

So, She volunteers for hours on weekend

=  

=

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
