A function is where there is only one output for every input. so when you plug in an x value, you should be getting only one y value.

it’s not the first one because you can see there are two points at (-1,0)
it’s not the second one because you can see there are two points at (0,0)
it’s not the fourth one because again there are two points at (-2,0) and (2,0)

it’s the third one because there is only one y value for every x value.

Misha Larkins [42]

Answer:

I think it is $3.25

Step-by-step explanation:

140*3=420- original price with 140 sold each day

130*3.25=422.5- 10 less hotdogs sold with $0.25 price increase

110*3.75=412.5- 30 less hotdogs sold with $0.75 price increase

90*4.25=391.5- 50 less hotdogs sold with $1.25 price increase

60*5.75=345-80 less hotdogs sold with $2.75 price increase

Temperature affects the speed of sound. The speed (v) of sound near Earth's surface, in

Bingel [31]

Answer:

The temperature in degrees Celsius is -48°C .

Step-by-step explanation:

The given equation is:

v = 20√[t + 273]

Therefore, rearranging we get:

(v / 20)² = t + 273

t = (v / 20)² - 273

but the speed of sound, v, is equal to 300 m/s

Therefore,

t = (300 / 20)² - 273

t = -48°C

Therefore, the temperature in degrees Celsius is -48°C .

The infant has apgar scores of 7 at 1 minute and 9 at 5 minutes. what is the indication of this assessment finding?

tatiyna

An infant may have had birthing complications that reduced the amount of oxygen in her blood if her Apgar score ranges from 7 at 1 minute to 9 at 5 minutes. In this situation, the hospital nurses will most likely vigorously dry her with a towel while holding oxygen under her nose.

<h3>What are Apgar scores?</h3>

The Apgar score is a recognized and practical way to report on the newborn baby's condition right after birth and their reaction to resuscitation, if necessary. One's particular neonatal mortality or neurologic prognosis cannot be predicted by the Apgar score alone, nor can it be regarded as a result of suffocation. It should also not be utilized to do so. An infant's spontaneous breathing score and the Apgar score given after resuscitation are not the same thing. An enhanced Apgar score reporting form that takes into account concurrent resuscitative treatments is encouraged by both the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists.
