First off, let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmm so what's the slope of y = 2x + 5?
well, notice, that equation is in slope-intercept form, thus

.

so, we're really looking for the equation of a line whose slope is -1/2 and runs through 1,4.
The answer to your question is C.

The LCM of 10,15,25 10 , 15 , 25 is 2⋅3⋅5⋅5=150 2 ⋅ 3 ⋅ 5 ⋅ 5 = 150 .
Answer:
Sphere Volume = (4/3) * PI * radius^3
Volume = (4/3) * PI * 19^3
Volume = 28,730.9120146298
Volume = 28,731 (when using PI = 3.14159265...
Volume = 28,716.3466666667
Volume = 28,716 cc answer is A.
