Step-by-step explanation:
A > -18/19 that should be the answer
Answer:
300pi ft³
Step-by-step explanation:
Volume of cylinder = pi×r²×h
Volume of cone = ⅓×pi×r²×h
Volume of cylinder is 3 times the volume of the cone
3(100pi) = 300pi ft³

Sorry i couldnt see the answers to number 5
Answer:
y - 2 = (-3/7)(x + 5)
Step-by-step explanation:
Recall that the slopes of a line and another line perpendicular to the first are negative reciprocals.
The slope of the given line is 7/3. The negative reciprocal of that is -3/7. Thus, we immediately eliminate the fourth answer choice.
We must now find the equation of the perpendicular line, with slope -3/7, that passes through (-5, 2). We'll do that using the point-slope formula for the equation of a straight line.
That formula is y - k = m(x - h), where m is the slope and (h, k) is the given point.
Substituting 2 for k, -5 for h and -3/7 for m, we get:
y - 2 = (-3/7)(x + 5). This matches the 3rd given possible answer.
