Find the sum of the first six terms of a geometric series in which a1 = 4 and r = -3: A. 729 B. -729 C. -728 D. 728 plz help
natta225 [31]

Answer:

C

Step-by-step explanation:

The sum to n terms of a geometric sequence is

S_{n} = \frac{a_{1}(r^n-1) }{r-1}

Here a₁ = 4 and r = - 3, thus

S_{6} = \frac{4((-3)^6-1)}{-3-1}

    = \frac{4(729-1)}{-4} = - (729 - 1) = - 728 → C

Which characteristics best describe an acute isosceles triangle?
Paladinen [302]
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees

We can rule out choice I since acut means less than 90

II is a possibility, but it doesn't best describe it

III. that is true, but it doesn't include the isocileese part

IV. that is true, but doesn't include the acute part

not sure, either III or IV

Please explain how I find the surface area and the answer please
docker41 [41]
You can take it apart. There are a top and bottom (both the same) right triangle. So you can find the area of that by multiplying 8*6 and divide by two. Then multiply by two because there are 2 triangles.
You are left with three rectangular sides: One 10x10, one 10x6, and one 10x8.
So your whole equation looks like this: A = 2[(8*6)/2]+(10*10)+(10*6)+(10*8)
