Answer: The reflection is: y' = -3x^2 + 4x - 1

Step-by-step explanation:

We have the parabola y = 3x^2 - 4x + 1

When we do a reflection in one of the two principal axis (x-axis or y-axis), the thing we need to do is multiply the other variable by -1 (if the reflection is done in the x-axis, we multiply y by -1)

We have that our new graph is the graph of -1*y, and this is = -1*(3x^2 - 4x + 1)

The reflection is: y' = -3x^2 + 4x - 1

Tyree and four friends go to the movies. Each person buys a movie ticket for $7, a snack for $5, and a drink for $2. Write an ex
Mandarinka [93]

Answer:

Tyree and all of his friends get 1 ticket for $7. Next they all get 1 snack for $5. Then they all get a drink for $2. So:

1=7

1=5

1=2

Then you take each person (which there are five of then) and you times all five people by 7, 5, 2.

5 x 7=35

5 x 5=25

5 x 2=10

After that you add it all together:

35 plus 25=60

60 plus 10=70

Step-by-step explanation:

your welcome

The base diameter and the height of a cone are both
WITCHER [35]

Answer:

11/ 42. *. X^ 2. * X = I/3 X A * h; if E = 1/3 A

Then the answer is EX

Step-by-step explanation:

Volume of cone= 1/3 * base area * height

= 1/3 * pi* (X/2)^2 * X

= 1/3. * 22/ 7 * X^3/4

= 22/ 21 * X^3 / 4

= 11/21 *. X^2/ 2. *. X

= 11/ 42. * X^3

= 11/ 42. *. X^ 2. * X
