Step-by-step explanation:

this is because it is right

The circumference of the larger circle is 2 times the circumference of the original circle.

Let r be the radius of the circle.

Then the area of the circle will be

A = πr² square units

The circumference of the circle will be

C = 2πr units

If the diameter of a circle doubles, the circumference of the larger circle.

Let d be the diameter of the circle.

Then the diameter of the small circle is d and the diameter of the other circle is 2d.

Then the ratio of the circumference of the circles will be

⇒ 2πr₂ / 2πr₁

⇒ 2r₂ / 2r₁

⇒ 2d / d

⇒ 2

The circumference of the larger circle is 2 times the circumference of the original circle.

Answer:

As

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Step-by-step explanation:

We know that the special theorem of remainder states that:

if

[tex]x-k[/tex] is a factor of [tex]p(x)[/tex]

then

[tex]p(k) = 0[/tex]

so

[tex]x+5 = x-(-5)[/tex]

[tex]k = -5[/tex]

Thus,

[tex]p(k) = 0[/tex]

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Answer:

vertex is (2 , -21)

x = -2 +√10

y = (x-3)²+1

Step-by-step explanation:

x² - 4x - 17

(x² - 4x + 4) - 4 - 17

(x-2)² - 21

vertex is (2 , -21)

2x² +8x = 12

x² + 4x = 6

(x² +4x + 4) - 6 - 4

(x+2)²  - 10

x+2 = √10

x = -2 +√10

y = (x-3)²+1

Answer:

idu it, the question but the euqation is x= -2y - 433 / 2 -5

Step-by-step explanation:

The radius of the circle is 4 units

The equation of the circle is given as:

(x + 5)^2 + (y - 3)^2 = 4^2

The general equation of a circle is given as:

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

Where r represents the radius

By comparing both equations, we have:

r^2 = 4^2

Take the square root of both sides

r = 4

Hence, the radius of the circle is 4 units

The least number of cabins needed for campers is 8.

Given that, Shady Rivers summer camp has 188 campers this week.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The least number of cabins needed = Total number of campers/Number of campers to each cabin

= 188/22

= 8.54

Therefore, the least number of cabins needed for campers is 8.

Answer: Point A

Step-by-step explanation:

The temperature at midnight is;

= 5 - 15

= -10°C

Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.

With point A being -10°C, it represents the colder midnight temperature.

Answer:

Point A

Step-by-step explanation:

We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).

We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.
