Answer:
The answer to the first question is B.
The answer to the second question is C.
Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation. We already have an x and y value. The derivative is found this way:

so

. The derivative supplies us with the slope formula we need to write the equation. Sub in the x value of 3 to find what the slope is:

. So in our slope-intercept equation, x = 3, y = 1, and m = -1/3. Use these values to solve for b.

so b = 2. The equation, then, for the line tangent to that hyperbola at that given point is
<span>y=x^2+5x+6
y=4x+12
Solution = (-3,0) and (2,20)
</span><span>y=x^2-3x-1
y=8x-1
Solution = (0,-1) and (11,87)</span>
Volume of a cone = pir^2h/3
so substitute what you know
1,102.14 = 3.14(r^2)(13/3)
divide by 3.14
351 = r^2(4.3333)
divde by 13/3
81 = r^2
r = 9 inches
The answer to your question is 7.94 that the perfect square root of 63
