The domain of the circle is [-4, 10]

The circle equation is given as:

(x - 3)^2 + (y + 1)^2 = 49

Express 49 as 7^2

So, we have

(x - 3)^2 + (y + 1)^2 = 7^2

The general circle equation is

(x - a)^2 + (y - b)^2 = r^2

Where the domain is

Domain = [a ± r]

So, we have

Domain = [3 ± 7]

Evaluate

Domain = [3 - 7, 3 + 7]

This gives

Domain = [-4, 10]

Hence, the domain of the circle is [-4, 10]

Problem 11

---------------

Work Shown:

The surface area of a 3D sphere is 4pi*r^2. So a hemisphere has surface area 2pi*r^2 since we cut the surface area in half.

Plug in r = 6 (half of the diameter 12) and we get 2pi*r^2 = 2pi*6^2 = 72pi

Now consider the circle with radius r = 6. Its area is pi*r^2 = pi*6^2 = 36pi

Add the two areas and we get 72pi+36pi = 108pi

Lastly, use your calculator to get 108pi = 108*3.1415926535898 = 339.292006587699 which rounds to 339

Problem 12

---------------

Explanation:

Look at where the "0" in the bottom sliding portion lines up with the number scale above. That "0" is between 19 and 20 mm. So you could argue that 19.2 and 19.5 are both valid answers, but I think 19.5 is the better answer since the tickmark seems to be right in the middle (more or less).

Step-by-step explanation:

surface area of hemisphere =3πr²

=3*3.14(6)²

=339.12m²

diameter of pipe= 19.5mm

Step-by-step explanation:

Given that

Thus, the equation becomes

[tex]14n + 17(6-n) = 99[/tex]

[tex]14n + 102 - 17n = 99[/tex]

[tex]-3n = 99 - 102[/tex]

[tex]-3n = -3[/tex]

Divide both sides by -3

[tex]n = 1[/tex]

and

[tex]6-n = 6-1 = 5[/tex]

Therefore, we conclude that:

Answer:

A

Step-by-step explanation:

perimeter = 2(x - 6y) + 2(8x² - x - 4y)

2x - 12y + 16x² - 2x - 8y

= 16x² - 20y units

Base is 2 times A over height= [tex](base)=\frac{2Area}{height}[/tex].

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure.

Area of a triangle is given by the formula;

                               [tex]A=\frac{1}{2} base * height[/tex]

Now, we need to solve for b. We multiply the right side, cross multiply,  and follow rules of algebra to isolate b. Shown below:

                         [tex]A=\frac{1}{2} base*height\\A=\frac{bh}{2} \\2A=bh\\b(base)=\frac{2A}{h}[/tex]

Thus, Base is 2 times A over height= [tex](base)=\frac{2Area}{height}[/tex].

Answer:

The answer is B

Step-by-step explanation:

Considering the definition of an equation and the way to solve it, the original price was $180.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear in addition to certain known data.

The solution of a equation means determining the value in which the equality must be true. To solve an equation, keep in mind:

Being "x" the original price, and knowing that:

The original price  can be calculated through the equation:

x - 0.35x= 117

Solving:

(1 - 0.35)x= 117

0.65x= 117

x= 117 ÷ 0.65

x= 180

Finally, the original price was $180.

Answer:

i. The distance between the balloon and canoe is 16.8 meters.

ii. The situation can be represented by: -12 + d = 4.8

Step-by-step explanation:

Let the surface of the lake be zero. Then any position above it is taken to be positive, while any position below is taken as negative.

So that,

the balloon's vertical position = 12 meters

the sunken canoe's position = -4.8 meters

Given that the distance between the balloon and the canoes is d, then:

d = balloon's position - canoe's position

  = 12 - (-4.8)

  = 12 + 4.8

d  = 16.8

The distance between the balloon and canoe is 16.8 meters.

Thus,

d = 12 -(-4.8)

d = 12 + 4.8

-12 + d = 4.8

The situation can be represented by: -12 + d = 4.8

The answer is option D it will take 8 hours 45 minutes to manufacture 7 windows.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The time will be calculated as follows:-

4 windows ------->   5 hours

1 window   --------> 5 / 4 hours

7 window  --------> 7 x ( 5 / 4 )

7 window  --------> 8.75 ≅ 8 hours 45 minutes

Therefore the answer is option D it will take 8 hours 45 minutes to manufacture 7 windows.

3 = red marbles

12 = total marbles

Answer:

Probability of both red =3(182)=3(18!2!16!)=3153

Step-by-step explanation:

Let Ai be the event in which the i-th ball you grab is red. For the first ball you choose, you have 3 red marbles out of a total of 18. Therefore,

P(A1)=318.

For the second marble you grab, given that you already took a red one, that is, given A1, you have 2 red balls out of a total of 17, then

P(A2∣A1)=217.

Finally,

P(A1∩A2)=P(A1)P(A2∣A1)=318217=151.

The result of the multiplication is the value of x (9x-3)​ is:  9x² - 3x.

Here, we have,

given that,

the expression is:  x (9x-3)​

now we need to find the value of x (9x-3)​

we have,

x (9x-3)​

=> x × (9x-3)​

so, we have to multiply this two terms.

now, we get,

=> x × (9x) - x × 3

=> 9x² - 3x

Hence, The result of the multiplication is the value of x (9x-3)​ is:  9x² - 3x.
