Answer:

y = x²

Step-by-step explanation:

A quadratic function is a polynomial function that has a variable to the power of 2 as the highest degree term. y = 1/x^2 is not a polynomial. y=2x is a linear function.

y = x^2 is a quadratic function

In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor sho

RoseWind [281]

Answer:

325,452 more meteors fell during the Perseid meteor shower

Step-by-step explanation:

An year has 365 days.

Each day has 24 hours.

Each hour has 60 minutes.

Minutes in an year:

365*24*60 = 525600

Persoid:

$1 + \frac{1}{5} = 1 + 0.2 = 1.2$

One each 1.2 minutes. How many during an year?

1 meteor - 1.2 minutes.

x meteors - 525600 minutes.

$1.2x = 525600$

$x = \frac{525600}{1.2}$

$x = 438000$

438,000 meteors fell during the Persoid shower.

Leonid:

$4 + \frac{2}{3} = 4.67$

One each 4.67 minutes. How many during an year.

1 meteor - 4.67 minutes.

x meteors - 525600 minutes.

$4.67x = 525600$

$x = \frac{525600}{4.67}$

$x = 112548$

112,548 meteors fell during the Leonid Shower.

How many more meteors fell during the Perseid meteor shower?

438,000 - 112,548 = 325,452

325,452 more meteors fell during the Perseid meteor shower

The table below shows the participation in the town soccer league during its first five seasons.

emmasim [6.3K]

Answer:

C. $y=6.75x+81.25$

Step-by-step explanation:

We are given that

In I year, number of participants=88

In V year, number of participants=115

We have to find the equation of the trend line that can be generated by using the data from years 1 and 5.

Rate of change of participants = $\frac{change\;in;participants}{change\;in\;time}=\frac{115-88}{5-1}$

Rate of change of participants,m=6.75

Point-slope form: $y-y_1=m(x-x_1)$

Where m=Rate of change of participants per year

$x_1=5,y_1=115$

By using the formula

Substitute the values then we get

$y-115=6.75(x-5)$

$y-115=6.75x-33.75$

$y=6.75x-33.75+115$

$y=6.75x+81.25$

Hence, option C is true.
