3. From birth, a normal person blinks an average of 25 times a minute when awake. When Katelyn was 10 years old, she blinked an average of 27 times per minute. When she was 11, she blinked 26 times per
minute. When she was 12, she blinked 25 times per minute. At 10 years old, Katelyn averaged 9 hours,
45 minutes of sleep each day; at age 11, she slept 9 hours, 30 minutes; at age 12, she slept 9 hours, 15
minutes. What is the sum of the number of times Katelyn blinked when she was 10, 11, and 12 years
old? (Use 365 days in a year).

im sorry but no. i just need to answer for 50 poonts oof

a ≈ 172.05

step-by-step explanation:

the pictures.

oof. u are asking for t much

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:
