Which equation represents a quadratic function?<br> y = x2<br> y = 2x<br><br> y =1/x^2
ehidna [41]

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

alisha [4.7K]

Answer:

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Step-by-step explanation:

  • Math session = 45 min = 3/4 hr
  • French session = 30 min = 1/2 hr
  • Number of math sessions = m, total math hours = 3/4m
  • Number of French sessions = f, total French hours = 1/2f

<u>Total hours constraint:</u>

  • 3/4m + 1/2f ≤ 30

<u>Number of session constraint:</u>

  • f ≤ 30

<u>So the system is:</u>

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Semmy [17]

Answer:

$95.38

Step-by-step explanation:

step 1

Find the area of one button

The area is equal to

A=\pi r^{2}

we have

r=9/2=4.5\ cm ---> the radius is half the diameter

Convert to meters

r=4.5\ cm=4.5/100=0.045\ m

assume

\pi =3.14

substitute

A=(3.14)(0.045)^{2}\\A=0.0063585\ m^2

step 2

Find the area of 1,00 buttons

Multiply by 1,000

A=0.0063585(1,000)=6.3585\ m^2

step 3

Find the cost

Multiply $15 per square meter by the total area of 1,000 buttons

(15)6.3585=\$95.38
