Graph (x+2)^2+y^2=100

  circle of radius 10 centered at (-2, 0)

Step-by-step explanation:

The equation is of the form ...

  (x -h)^2 +(y -k)^2 = r^2

with (h, k) = (-2, 0) and r=10.

This is the standard form of the equation of a circle with radius r centered at (h, k).

See the attached for a graph.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
