This is the formula of finding the hypotenuse: a² + b² = c².
So the legs would be a and b.
4² + 4² = c²
c² = 16 + 16
c² = 32
c = √32 (Option C)
Answer:
B
Step-by-step explanation:
When we see "square inches" in a statement (or squared centimeters, meters, feet, etc) this refers to an area measure. So we need to find which of the options are areas.
A is not, as it is width, is a longitude measure. I could never be in square inches.
C is volume and it measure should be in cubic inches. So, not.
D is perimeter and is the sum if the lengths of different sides of a figure, so is also in inches, not square inches.
Finally, B is the area, so is our only chance. B in correct.
Answer:
Step-by-step explanation:
if the angles c and l were marked with the angle curve like angles j and a
If the vertex is at the maximum point they dy/dx=0 at that point...
dA/dx=-2x+4
dB/dx=-2x+8
dC/dx=2x-4
dD/dx=2x-8
So both B and D have a zero velocity at x=4, but only B is equal to 3 when x=4
B. is the correct quadratic with the vertex at (4,3)
Step-by-step explanation:
a^2+b^2=c^2
3^2+9^2 not equal to 12^2
