Andre received $60 for his birthday and put it in his piggy bank. Each week, he put 3 more dollars in the bank. The amount of mo

ney in dollars D in his bank is given by D = 3w + 60, where w is the number of weeks he has saved 3 dollars. His sister Lana makes a table of reasonable values for w. Lana selects 12 as a value for w.
What is the corresponding table entry for D?

Answer:

96 (dollars)

Step-by-step explanation:

D represents the amount of money Andre has in his bank after w weeks.  This formula is written as D(w) = 3w + 60 (dollars).

After 12 weeks, Andre will have accumulated D(12) = 3(12) + 60 dollars, or

36 + 60 dollars, or 96 dollars.  This is answer choice B.

Find the tangent line equation of the curve at the given point. Y=arcsin(7x) at the point where x=sqrt2/14
Mumz [18]

Answer:

Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})

Step-by-step explanation:

The equation of the curve is

Y = sin^{-1}(7x)

To find the equation of tangent we need to differentiate this equation w.r.t x

So, differentiating we get

Y'=\frac{7}{\sqrt{1-49x^2} }

This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is  x = \sqrt{\frac{1}{7} }

Then slope would accordingly be

Y'=\frac{7}{\sqrt{1-49/49} }

= ∞

For, x = \sqrt{\frac{1}{7} }, Y = sin^{-1}(7/7)= \pi/2

Equation of tangent line, in the point slope form, would be Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})
