Answer:
3, 6, 9, 12 is not geometric
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms.
3, 6, 9 , 12
has a common difference of 3 between terms and is arithmetic
1, 5, 25, 125
r = 5 ÷ 1 = 25 ÷ 5 = 125 ÷ 25 = 5 ← geometric
4, 8, 16, 32
r = 8 ÷ 4 = 16 ÷ 8 = 32 ÷ 16 = 2 ← geometric
2, 6, 18, 54
r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 ← geometric
Answer:
57.5
Step-by-step explanation:
if you break it down into smaller shapes, there's a semicircle, three triangles and a rectangle.
circle πr² = π 2² = 4π² = 39.5
triangle 1 bh = (3)(2) = 6
triangle 2 bh = (4)(1) = 4
triangle 3 bh = (2)(4) = 8
Add them all up to get total area
6 + 4 + 8 + 39.5 = 57.5
First you need to find the circumference of the circle because 1 revolution is 1 length of the circumference. The formula for the circumference is C=2πr or C=πd, if the diameter is 1 meter then the circumference is π1 which is just π, and if it travelled 8000 rotations then that would mean it travelled 8000π, so it travelled 8000π in meters
Answer:
So the question is asking you to write an expression which can be defined as a mathematical equation that contains two numbers (usually a <u>variable</u> represented by a letter from the english alphabet and a <u>constant</u> like 1, 2, 15, 73, or 10) and at the very least, one operation. So we are instructed to write an expression WITH an exponent. Examples of exponents would be squaring or cubing a number: 2² or 5³
With this kind of problem its more of a guess and check to try and see which numbers would make the equation true/equal to 24.
Here is an example of what I would put down:
24 = 3x³
24/3 = x³
8 = x³
2 x 2 x 2 = x³
2 = x
Check by plugging our x-value in:
24 = 3 x 2³
24 = 3(8)
24 = 24
