Write the equation of a circle with a center at (6, 7) and a diameter of 4.
posledela

Answer:

(x - 6)² + (y - 7)² = 4

Step-by-step explanation:

Equation of circle: (x - h)² + (y - k)² = r²

Given center(h,k) = (6,7)

h = 6

k = 7

Dimeter = 4 --

radius, r = \frac{4}{2} = 2

(x - h)² + (y - k)² = r²

(x - 6)² + (y - 7)² = 2²

(x - 6)² + (y - 7)² = 4

KatRina [158]

Step-by-step explanation:

look at the picture !

she has to paint actually 6 rectangles :

the 3 tops of the 3 stairs.

and the 3 vertical front boards (the front of each step of the stairs).

what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.

each top rectangle is clearly

82×19 (19 cm deep) = 1558 cm²

each front board is

82×12 (12 cm high) = 984 cm²

so, in total we have

3×1558 + 3×984 = 4674 + 2952 = 7626 cm²

as surface area to be painted.

What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 2? (5 points)
tiny-mole [99]
The third choice is appropriate.
  an = 5 - 3(n - 1); all integers n ≥ 1

_____
This equation follows the form for the general term of an arithmetic sequence.
  an = a1 + d(n - 1)
where a1 is the first term (corresponding to n=1), and d is the common difference. From the problem statement, a1 = 5 and d = 2 - 5 = -3.
