Answer:
D.
Step-by-step explanation:
A function, by the easy-to-understand definition, is a relation where no x values are shared. The only set where each x value is different is in D. All the other sets share the same x value. Example: Set C has coordinates (-2, 1) and (-2, 2). The x coordinates are the same, so this isn't a function. It is only a relation.
Answer:
523.6 cm^3
Step-by-step explanation:
We know the diameter is 10. The radius is half the diameter, so 10/2=5.
Knowing the radius is 5, we just need to plug it into the formula.
Volume=(4/3)pi5^3
≈523.6
Answer:523.6 cm^3
Answer:
9 sqrt(2) /2 = PQ
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = PQ = 9
9 sin 45 = PQ
9 sqrt(2) /2 = PQ
X=percentage in decimal
30x=6
30/30x=6/30
x=1/5=.20
.20=20/100=20%
20%
Y-axis, because what i’ve been taught with coordinates, is you crawl before you walk which means is first it’s x-axis then y-axis. so (0,4) would be on the y-axis. :)
