Answer:

-1

Step-by-step explanation:

Assuming problem is: x->2 (x^3 -3x^2 +3)

Since the expression is continuous at x=2,

then the limit can be found just by evaluating the expression at x=2.

2^3-3(2)^2+3

8-3(4)+3

8-12+3

-4+3

Andre wants to make a scaled copy of jada drawing so the side that corresponds to 4 units in jada polygon is 8 units of his scal

Contact [7]

Answer:

No she should add extra lengths

Step-by-step explanation:

The difference between scaled copy and jada drawing is that it is in the ratio

8:4

2:1

that is the scaled copy is twice as large as the jada drawing itself.

So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.

at a movie theatre, child admission is $6.40 and adult admission is $9.70. on Wednesday, 128 tickets were sold for a total sales

grandymaker [24]

Answer: 74 adult tickets were sold on Wednesday.

Step-by-step explanation:

Let x represent the number of child admission tickets sold on Wednesday.

Let y represent the number of adult admission tickets sold on Wednesday.

On Wednesday, 128 tickets were sold. It means that

x + y = 128

At the movie theatre, child admission is $6.40 and adult admission is $9.70. The total ticket sales on Wednesday was $1063.40. It means that

6.4x + 9.7y = 1063.4- - - - - - - - - - 1

Substituting x = 128 - y into equation 1, it becomes

6.4(128 - y) + 9.7y = 1063.4

819.2 - 6.4y + 9.7y = 1063.4

- 6.4y + 9.7y = 1063.4 - 819.2

3.3y = 244.2

y = 244.2/3.3

y = 74

x = 128 - y = 128 - 74

x = 54
