It could be solved by analyzing the questions and finding important words that stand out to you. 20=16+4 , 50=10+40. this is the way you find it
If tangent to the curve y = √x is parallel to the line y = 8x, then this implies that the tangent to y = <span>√x has the same slope as the line y = 8x. In other words, the derivative (slope) function of y = √x is equal to the slope of the line y = 8x, which is m = 8. Hence y' = 8 once we find y'
y = </span><span>√x = x^(1/2)
Applying the power rule and simplifying, we find that the derivative is
y' = 1/(2</span>√x)
Now remember that y' must equal 8
1/(2<span>√x) = 8
Multiplying both sides by 2</span><span>√x, we obtain
1 = 16</span><span>√x
Dividing both sides by 16, yields
</span><span>√x = 1/16
But wait a minute, √x = y. Thus 1/16 must be the y-coordinate of the point at which the tangent to y = √x is drawn.
Squaring both sides, yields
x = 1/256
This is the x-coordinate of the point on the curve where the tangent is drawn.
</span><span>∴ the required point must be (1/256, 1/16)
GOOD LUCK!!!</span>

Answer:
76800
Step-by-step explanation:
Current subscriber=4800
After 3 years=2*4800=9600
After 6 years=2*9600=19200
After 9 years=2*19200=38400
After 12 years=2*38400=76800
Answer:
see below
Step-by-step explanation:
Equilibrium quantity means the quantity supplied at a given price is equal to the quantity demanded at that price. To find it, look for the line in the table where quantities are equal. That line tells you the equilibrium price as well as quantity.
_____
On a graph, it is the point where supply and demand curves intersect (quantities are the same at the corresponding price).
