<h3>What is a Function ?</h3>

A function is a mathematical statement that relates a dependent variable and an independent variable.

It is given that

f(x) = x²

It has been asked to determine the equation of g(x)

It can be seen from the graph the the vertex is same just the graph is scaled.

The point (3,3) is of g(x) , when the value of y at at x =3 is 9

Therefore the scale factor is 1/3

And we can do trial and error on the basis of the options given ,

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

C) How long is the potato in the air? *hint set h=0*<br> if h=-2(t-3)2+32
Galina-37 [17]

Answer:

if you meant to put (t-3)^{2}, then the answer is 7

Step-by-step explanation:

h=-2(t-3)^{2}+32

solve for t

0=-2(t-3)^{2}+32

subtract 32 from both sides

-32=-2(t-3)^{2}

divide both sides by -2

16=(t-3)^{2}

find suare root of 16

4= t-3

add 3 to both sides

7 = t

I need help with this,, will give brianliest and +15 points
Anit [1.1K]

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27

A total of 479 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer stu
irina [24]

Say the number of adult tickets is x. That means the number of student tickets is 71 less, making it x - 71.

We can add the number of student and adult tickets, because we know their sum is 479.

x + x - 71 = 479

Now, we solve for x.

2x - 71 = 479

2x = 550

x = 275

So, there were 275 adult tickets sold.
