Find the center and radius of the circle with equation (x+3)^2+(3+ 1)^2= 9. Then graph the circle.

Ymorist [56]

Answer:

See graph

$(x +3)^{2}$ + $(y + 1)^{2}$ = 9

(-3 , -1) is the center.

$\sqrt{9}$ = 3 = radius

Step-by-step explanation:

$(x - h)^{2} + (y - k)^{2} = r^{2}$

center (h,k)

radius = r

Answer:

<em>The width of the lid is 15 cm</em>

Step-by-step explanation:

<u>The Perimeter of a Rectangle</u>

Given a rectangle of width W and height H, the perimeter is calculated as:

P = 2(W + L)

Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:

2(W + L) = 56

Dividing by 2:

W + L = 28

Since the lid was L=13 cm long, the width is:

W = 28 - 13 = 15

The width of the lid is 15 cm

Answer:

The complete question is defined in the attached file please find it.

Step-by-step explanation:

For question 1:

$\to 4-(3+1)^2 - 6\div 2 +4 \\\\\to 4-(4)^2 - 6\div 2 +4\\\\\to 4-16 - 3 +4\\\\\to 4-19 +4\\\\\to 4-15\\\\\to -11$

For question 2:

$\to 7x^3 +2x -5x^2+6+ x+ 9+ 3x^3 +12x^2 \\\\\to 7x^3 +3x^3+12x^2 -5x^2+2x+x+9+6 \\\\\to 10x^3 +7x^2+3x+15 \\\\$

For question 3:

$\to (2x^5- 3x^2+4)-(x^5+2x^2+7)\\\\\to 2x^5- 3x^2+4-x^5-2x^2-7\\\\\to x^5- 5x^2-3\\\\$

For question 4:

$\to 3x^2(4x^3- 2x^2+7x -4) \\\\\to 12x^5- 6x^4+21x^3 -12x^2 \\\\$

For question 5:

$\to 6x^2+9x-7 \ \ \text{when} \ \ x=2\\\\\to 6(2)^2+9(2)-7 \\\\\to 6(4)+9(2)-7 \\\\\to 24+18-7 \\\\\to 24+11 \\\\\to 35$

There are 36 tickets sold for a raffle for the Student Art Auction, and there are two prizes to be awarded. Dionte buys two tick

anyanavicka [17]

Given :

There are 36 tickets sold for a raffle for the Student Art Auction, and there are two prizes to be awarded.

Dionte buys two tickets.

To Find :

The probability that he will win both price.

Solution :

Number of prizes available, p = 2

Probability of getting price from first draw :

$P_1=\dfrac{2}{36}\\\\P_1=\dfrac{1}{18}$

Probability of getting price from second draw if he won first prize :

$P_2=\dfrac{2-1}{36-1}\\\\P_2=\dfrac{1}{35}$

So, probability of winning both prize :

$P=P_1\times P_2\\\\P=\dfrac{2}{36}\times \dfrac{1}{35}\\\\P=0.00159$

Therefore, probability of winning both prize is 0.00159 .

Hence, this is the required solution.
