Step-by-step explanation:
Part 1
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Given = 128, then
a = 128, that is
32a = 128 ( divide both sides by 32 )
a = 4 ← first term
Part 2
= 4 = 4 × 1048576 = 4194304
Answer:
A
Step-by-step explanation:
Just divide 44 by 2 and it would give u the answer, Hope this helps :)
Answer:
$1,221

Answer:
60 inches or 5 feet
step-by-step explanation:
10 ft can be turned into 120 in
120/2
60 inches or 5 feet
The figure of the prism is attached below.
The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.
Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units
There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.
So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units
The Surface Area of the prism will be:
Surface Area = 2 (4) + 72 = 84 square units
Thus the correct answer is option A
