Answer: Yes
Step-by-step explanation:
To solve this, imagine you have a vertical line. You can use a ruler or something straight. Move the ruler across the screen. Does the ruler intersect 2 points at once? If so, then it is not a function. If it only intersects one point, then it is a function.
Always remember: a function cannot have two x's with different y-values.
Hope that helped!
Answer:
Step-by-step explanation:
To find the breadth use Pythagorean theorem
Breadth² = diagonal² - length²
= 34² - 30²
= 1156 - 900
= 256
Breadth = √256 = 16 cm
Breadth = 16 cm
Perimeter = 2*(length + breadth) = 2*(30 + 16) = 2*46 = 92 cm
Area = length * breadth = 30 *16 = 480 cm²
If it’s proportional, then when X is 1, y is 2.6, you get that by dividing 275.5 by 29
so when y is 408.5, x is 156.91
I believe that is correct.
