Two-dimensional figures are one category and polygons are a separate category that falls under two-dimensional because 2D(two dimensional) figures are figures that do not have a volume so they are flat. Polygons are flat 2D shapes that have straight lines and all lines are closed, meaning that they don't have any disconnected lines. Polygons are a subcategory of 2D figures because they carry all traits of 2D figures but also have special ones of their own. Examples of polygons are squares, rectangles, and triangles. Examples of nonpolygons but still are 2D figures are circles, ovals, and any other flat shape.
f(x)= -99.4x + 198.8
f(1) = -99.4*1 + 198.8 = 99.4
f(2) = -99.4*2 + 198.8 = 0
f(3) = -99.4*3 + 198.8 = -99.4
<span>f(4) = -99.4*4 + 198.8 = -198.8

The adequate intake (AI) for potassium is 4,700 mg in healthy individuals, but unfortunately, most people don’t get enough potassium through their diets. one medium-sized banana typically containing 422 mg. One half of an avocado (100 grams) contains 487 mg of potassium. One cup (156 grams) of frozen spinach contains 540 mg of potassium. One medium-sized sweet potato contains 541 mg of potassium. Just two wedges of watermelon (about 1/8 of a melon or 572 grams) will give you 640 mg of potassium. Three tablespoons of tomato paste or about 50 grams contain 486 mg of potassium. Pomegranates are fantastic source of potassium, as one fruit can bestow 666 mg. One potato can provide 515 mg of potassium.

Answer:
-49
Step-by-step explanation:
multiply 7 with 7 then i with i and lastly multiply the result numbers
7i × 7i ➡ 7 × 7 = 49
i × i = i^2
49 × i^2 = 49i^2
i^2 = -1 ➡ 49 × (-1) = -49
Answer:
b
