Answer: j = 8
Step-by-step explanation: To solve for <em>j</em> in this equation, we want to get <em>j</em> by itself on the left side of the equation. Since <em>j</em> is being multiplied by 5, to get <em>j</em> by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out so we are simply left with <em>j</em>. On the right side, we have 40 divided by 5 which gives us 8 so we have j = 8.
Finally, remember to check your answer by substituting an 8 back into the original equation. So we have 5 (8) = 40 which is a true statement so our answer checks. Remember to show all your work when solving equations.
Answer:

Step-by-step explanation:
given,
radius of sphere = 3
volume of cone:

r is the radius of circular base
h is the height of the cone
here r = x and h = 3 + y
now, volume in term of x and y

Applying Pythagoras theorem
x² + y² = 3²



differentiating both side

for maxima 

y² + 2 y - 3 = 0
(y+3)(y-1)=0
y = 1,-3
y cannot be negative so, volume at y = 1


Hence, the largest cone which can be inscribed in the spheres of the radius 3 has volume

Answer:
Positive, linear equation.
Step-by-step explanation:
Even though the graphs coordinates looks a little dicey, all of the points are still going upward which is a positive linear equation.
