The equation of circle in standard form can be represented as :

where,
- h = x - coordinate of centre = 0
- k = y - coordinate of centre = 0
- r = radius of circle = 6 units
now, let's plug in the values :


That's the required equation of circle.
Answer:
15.5 ft²
Step-by-step explanation:
The area (A) of a regular polygon is calculated as
A =
pa ( p is the perimeter and a the apothem )
Here side of regular pentagon is 3 ft, thus
perimeter = 5 × 3 = 15, so
A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )
Answer:
A and A
the equation of a parabola in vertex form is
y = a(x - h)² + k
where ( h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x + 3)² + 2 is in this form
with vertex = ( - 3, 2)
To find the y-intercept let x = 0
y = - 2(3)² + 2 = - 18 + 2 = - 16
Similarly
y = - 2(x + 2)² + 2 is in vertex form
vertex = ( - 2 , 2)
x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept
hope this helped
Answer:
The mean is 4
Step-by-step explanation:MRK ME BRAINLIEST PLZZZZZZZZZZZZZz
ita 4 because first you add up the 10,3,2,5,0. and then it equals 20 and then divided and get the mean which is 4
Answer:
x = 3
Step-by-step explanation:
Two triangles are similar
x/(x+3) = 4/8 cross multiply expressions
8x = 4x + 12
8x - 4x = 12
4x = 12 divide both sides by 4
x = 3
