Hey there!

Answer:\boxed{(-1,8)}

Explanation:

-x^2 - 2x + 7

How many positive integers less than 100 have at least one digit that is a 9? (Let T be the set of positive integers less than 1
Ymorist [56]

Answer:

19

Step-by-step explanation:

Let T be the set of positive integers less than 100 with a 9 in the ten's place.

T = {90, 91, 92, 93, 94, 95, 96, 97, 98, 99}

n(T) = 10

Let O be the set of positive integers less than 100 with a 9 in the one's place.

O = {9, 19, 29, 39, 49, 59, 69, 79, 89, 99}

n(O) = 10

The common element is 99.

T\cap O={99}

n(T\cap O)=1

The union of both sets is

n(T\cup O)=n(T)+n(O)+n(T\cap O)

n(T\cup O)=10+10-1

n(T\cup O)=19

Therefore, 19 positive integers are less than 100 those have at least one 9.

3. Rhombus KLMN with vertices K(-3, 2), L(1, 4),<br> and N(-5, -2): (x,y) → (x+2, y-5)
Art [367]

The translated vertices of the rhombus are: K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7)

The rhombus is a parallelogram which has all sides equal. the diagonals of a rhombus bisect at right angles. the difference between a rhombus and a square is that none of the angles of a rhombus are 90°.

To translate a figure with given co-ordinates into another figure with a particular translation we simply add or subtract the given values from the coordinates of the available points.

Given co-ordinates of Rhombus are K(-3, 2),L(1, 4),M(-1 ,0)and N(-5, -2).

The translation is given as (x,y) → (x+2, y-5)

So we calculate the coordinates as:

The translated co-ordinate  K(-3, 2)→ K'(-1,-3)

The translated co-ordinate  L(1, 4)→  L'(3,-1)

The translated co-ordinate  M(-1 ,0)→ M'(1,-5)

The translated co-ordinate N(-5, -2)→ N'(-3,-7)

Hence the co-ordinates of rhombus translated by  (x,y) → (x+2, y-5) are  K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7).
