Find the absolute maximum and minimum of the function on the given domain. f (x comma y )equals 8 x squared plus 7 y squared on

pickupchik [31]

Answer:

the maximum value is 7

The minimum value is 0

Step-by-step explanation:

Step One : Interpret the question

The above question can be written like

The Equation

$f(x,y) = 8x^2 +7y^2$

The diagram of the triangular plate and the bounded lines is shown on the first uploaded image

From the diagram $f(0,0) = 8(0)^2 +7(0)^2 =0$

$f(1,0) =8(1)^2 + 7(0)^2 = 8$

$f(0,1) =8(0)^2 + 7(1)^2 = 7$

Partial differentiation of the equation w.r.x

$A =\frac{\delta f}{\delta x } = 16x$

Partial differentiation of the equation w.r.y

$B =\frac{\delta f}{\delta y } = 14y$

Looking at the diagram the maximum value is 7 i.e at (x , y) = (0,1)

The minimum value is 0 i.e (x , y) = (0,0)

If John invests $600 in a savings account earning interest at a rate of 6% compounded semiannually how much will be in account a

kondaur [170]

Answer:

$962.82 will be in John's account after 8 years if compounded semiannually.

Step-by-step explanation:

The formula used to find the amount after 8 years is:

A = P(1+ r/n)^nt

Where A = future value

P= principal value

r = interest rate ( in decimals)

n = no of times interest is compounded

t = time

Putting the values:

P = $600

r = 6% = 0.06

n = 2

t = 8

A= 600 *(1+0.06/2) ^2(8)

A= 600 *(1.03) ^16

A =600*1.605

A = 962.82

So, $962.82 will be in John's account after 8 years if compounded semiannually.
