Answer:

(x + 4)² + (y - 2)² = 8

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (- 4, 2 ) , then

(x - (- 4))² + (y - 2)² = r²

(x + 4)² + (y - 2)² = r²

CA is the radius of the circle

To find r use the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = C(- 4, 2) and (x₂, y₂ ) = A(- 2, 4)

r = [tex]\sqrt{(-2+4)^2+(4 -2)^2}[/tex]

  = [tex]\sqrt{2^2+2^2}[/tex]

  = [tex]\sqrt{8}[/tex] , then r² = ([tex]\sqrt{8}[/tex] )² = 8

Then

(x + 4)² + (y - 2)² = 8 ← equation of circle

Answer:

option c

Step-by-step explanation:

The angles are 30° , 60° , 90° . So its a right angled triangle . We can use trigo.

⇒ sin 30 = p/h

⇒ 1/2 = p/10

⇒ p = 10/2

⇒ p = 5

Using Cosine now ,

⇒ cos 30° = b/h

⇒ √3/2 = b/10

⇒ b = √3/2 × 10

⇒ b = 5√3

A) 75

Step-by-step explanation:

BC = c

a² + b² = c²

21² + 72² = c²

441 + 5184 = c²

c² = 5625

[tex]\sqrt{c^2} =\sqrt{5625}[/tex]

c = 75

Step-by-step explanation:

Answer:

0.5n < 12.5

n < 25 days

Step-by-step explanation:

Total gallons of fuel = 14 gallons

Warning light comes on when the remaining fuel is 1.5 gallons or less

Gallons of fuel used without warning light = 14 gallons - 1.5 gallons

= 12.5 gallons

Gallons of fuel used per day = 0.5 gallons

Number of days = n

inequality to determine the number of days diego's father can drive the car without the warning light coming on.

0.5n < 12.5

n < 12.5/0.5

n < 25 days

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.

Step-by-step explanation:

The largest perfect square factor of 84 is 4.

We know that, a factor is a number that perfectly divides the number with 0 as remainder.

The easiest way to find out factors of a number is by doing LCM.

The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.

From all the above factors 4 is the only number that is a perfect square.

Therefore, the largest perfect square factor of 84 is 4.

Answer:

7.22 feet

Step-by-step explanation:

From the question,

s = d/t................. Equation 1

Where s = speed of the space shuttle, d = distance traveled by the shuttle in an hour, t = time taken to travel the distance

make d the subject of the equation,

d = s×t.................... Equation 2

Given: s = 2.6×10000 feet per seconds, t = 1 hour =  3.6×1000 seconds.

Substitute these values into equation 2

d = (2.6×10000)/(3.6×1000)

d = 26000/3600

d = 7.22 feet.

Hence the shuttle travels 7.22 feet in an hour

The area of that should be painted by Kim is 55.75 ft².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that a container which is in shape of rectangular prism,

We need to find the area that should be painted,

So, to find the same we will find the surface area of the prism,

SA = 2(lh + hw + wl)

l = length, w = width and h = height,

SA = 2(2.50·4 + 2.75·2.50 + 2.75·4)

= 2(10 + 6.875 + 11)

= 2 × 27.875

= 55.75

Hence the area of that should be painted by Kim is 55.75 ft²
