What is the equation of a circle with a center located at (4, -1) and a radius of 9?

Answers

Answer:

(x-4)^2 + (y+1)^2 = 81

Step-by-step explanation:

you clearly have internet access and could have very quickly searched for the equation of a circle.

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

with (h,k) being the center.

=> (x-4)^2 + (y+1)^2 = 81

Pls someone help I need help with 2 I need answer and explanation pls

Answers

Answer:

2. B, 18 = 11 + 7

If you plug in the 7 in the y it would make sense

18 = 11 + y

Let's plug in the 7

18 = 11 + 7

and 11 + 7 = 18, so it makes sense! Therefore B is your answer for question number 2.

Answer:

B. 18 = 11 + y

Step-by-step explanation:

since y = 7

substitute it into the equation which becomes

18 = 11 + 7

which makes this statement true.

11 + 7 = 18

Find the measure of the arc TDB in the circle P shown below:

Answers

[tex]\huge{ \mathfrak{  \underline{ Answer \:  \:  ✓ }}}[/tex]

The Angle formed by an arc on the centre of the circle is double the angle made by the same arc on the circumference of the circle.

So,

[tex] \boxed{ \mathrm{ \angle TDB = \dfrac{1}{2} \angle TPB }}[/tex]

[tex] \mathrm{\angle TDB = \dfrac{1}{2} \times 90 \degree}[/tex]

[tex] \mathrm{\angle TDB =45 \degree } [/tex]

answer: b=126

explanation: since the outer ring of the circle is 360 degrees, i took 360 and subtracted 108. then, since the other two sectors are equal to each other, i took the answer of 360-108 which is 252 and divided it by 2 to get 126.

Q2)You are trying to save $1500. You begin with $5 and save $3 more than the previous amount each week for 30 weeks. Will you meet your goal? Explain. Show work

Answers

Solution :

First term, a₀ = -10 .

Common difference of A.P. , d = -8 - (-10) = 2 .

Last term, aₙ = 24 .

We know, last term is given by :

aₙ = a₀ + (n-1)d

24 = -10 + (n-1)×2

2n - 2 = 34

n = 18

Now, sum of series is given by :

[tex]S_n = \dfrac{n}{2} \times ( 2a+(n-1)d)\\\\S_n = \dfrac{18}{2} \times ( 2\times -10 + ( 18 -1) \times 2)\\\\S_n = 126[/tex]

Hence, this is the required solution.

Mark: 10x

Tim: 9x

Jane: 8x

(10x - 5) + (9x - 5) + (8x - 5) = 39

10x - 5 + 9x - 5 + 8x - 5 = 39

27x - 5 - 5 - 5 = 39

27x - 15 = 39

27x - 15 + 15 = 39 + 15

If the length of qr is 8 cm and the length of qs is 12 cm, what is the length of rs? No links Pls

Answers

Answer:

8.94

Step-by-step explanation:

Given that

qs = 12cm

qr = 8cm

Required  

rs

Using the pythagoras theorem

Let us assume qs is the hypotenuse side

qs² = qr² + rs²

12² = 8² + rs²

144 = 64 +rs²

rs² = 144 - 64

rs² = 80

rs = √80

rs = 8.94

Hence the value of rs is 8.94

The width of a rectangle is its length. The perimeter of the rectangle is 420 ft.
What is the length, in feet, of the rectangle?

Answers

Width=length

Let's assign a variable for the width, and call it x.

Since the width is equal to it's length, we can also call the length x.

The perimeter formula for a rectangle is 2(l+w).

Hope this helps!

Answer:

[tex]105ft[/tex]

Step-by-step explanation:

Since it's saying that the width of a rectangle is its length, that means all the sides of the rectangle are equal.

Since a rectangle has only 4 sides, we can divide the perimeter of the rectangle (420 ft) by 4 (sides)

Note: perimeter is the sum of all sides!

420 ÷ 4 = 105

In the design shown below, four semicircles are attached to a square whose area is 36 square centimeters. Which of the following is closest to the total area of the shaded semicircles, measured in square centimeters?

Answers

Answer:

56.549 cm   (choice 1)

Step-by-step explanation:

If the area of the square if 36 cm, then each side is 6 cm.

That means the diameter for each semi circle is also 6 cm.

Formula for a semi circle is 1/2(πr²)

We need the radius, which is half the diameter. So the radius is 6÷2= 3

Now plug in to the formula.

A= 1/2(π3²)

A= 14.137 (nearest hundredths)

Now multiply that by 4, because there are 4 semi circles

4(14.137)= 56.549 cm (nearest hundredths)
