maybe bc of how many times you can add the number itself
Answer:
5:3
Step-by-step explanation:
to find the scale factor you set up the proportion as 15/9 and reduce to 5/3

Answer: 16 square units</h3>
Let x be the height of the parallelogram. Right now it's unknown, but we can solve for it using the pythagorean theorem. Focus on the right triangle. It has legs a = 3 and b = x, with hypotenuse c = 5
a^2 + b^2 = c^2
3^2 + x^2 = 5^2
9 + x^2 = 25
x^2 = 25-9
x^2 = 16
x = sqrt(16)
x = 4
This is a 3-4-5 right triangle.
The height of the parallelogram is 4 units.
We have enough info to find the area of the parallelogram
Area of parallelogram = base*height
Area of parallelogram = 4*4
Area of parallelogram = 16 square units
Coincidentally, the base and height are the same, which isn't always going to be the case. The base is visually shown as the '4' in the diagram. The height is the dashed line, which also happens to be 4 units long.
Answer:
the 73rd term of the arithmetic sequence is -964.
Step-by-step explanation:
The common difference in this arithmetic sequence is 13. This is obtained by subtracting 28 from 41. The first term is a(1) = -28.
The arithmetic sequence formula is a(n) = a(1) + d(n - 1), where d is the common difference and -28 the first term.
Then, in this case, a(n) = -28 - 13(n - 1), and
a(73) = -28 - 13(73 - 1) = -964
