The transformation negates the y-coordinate, so reflects a point across they x-axis.
C is correct.
Reasoning: If the top number (numerator) is smaller that the bottom number (denominator), it means it’s smaller than 1. If, on the other hand, the numerator is bigger than the denominator, it means it’s more than 1. If youre ever unsure, devide the numerator by the denominator. This will turn the number into a decimal, and be easier to see. 8/9 = 0.88 repeated, and 3/7 = 0.4285. Therefore 8/9 is larger than 3/7. This can also be written as 8/9 > 3/7.
Good luck!
We know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere
if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere
if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere
examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area
2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area
3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area
Answer:
y= -4x + 54
Step-by-step explanation:
4x + y =54
-4x -4x
y = -4x +54
Answer:
4
Step-by-step explanation:
2/3 for 1 jar | meaning that: 1 jar: 1 cup (1/3 left) | 1 jar: 1 cup (1/3 left) | 1 jar: 1 cup (1/3 left) | 3/3 are left, and that makes another one (the 4th one).
