Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 5 sin(xy), (0, 2) maximu
Ahat [919]

Answer with Step-by-step explanation:

We are given that

f(x,y)=5 sinxy

Point=(x,y)=(0,2)

We have to find the maximum rate of change of f at given point.

f_x(x,y)=5ycos(xy)

f_x(0,2)=5(2)cos0=10

f_y(x,y)=5xcosxy

f_y(0,2)=5(0)cos0=0

\Delta f(0,2)=f_x(0,2)+f_y(0,2)=10i+0j

Maximum rate of change of f at point (0,2)=\mid \Delta f(0,2)\mid=\sqrt{x^2+y^2}

Where x=Coefficient of i

y=Coefficient of j

By using the formula

Maximum rate of change of f at point (0,2)=\sqrt{(10)^2+0}=10

Direction of maximum rate of change of f=\Delta\har{f}=\frac{\Delta f(0,2)}{\mid\Delta f(0,2)\mid}=\frac{10i}{10}=i

Can someone help me out with this question? The question is about circle diameters. I'm unfamiliar with finding the length of th
Nady [450]

Answer:

a) m arc AD = 145

b) D = 10

Step-by-step explanation:

a) mAD can be found because triangle OCM can be shown to be congruent to triangle ODM.

The angle AOD is supplementary to DOB which we just showed to be congruent to the known 35° angle COB. Therefore AOD = 180 - 35 = 145°

The arc length is identical to the arc angle when measured between radii.

b) The radius OC = √(OM² + (CD/2)² = √(3² + 4²) = 5.

Diameter is twice radius = 10

Given f(x)= √7x and g(x) = 1/x-8 which value is in the domain of f^o g
bekas [8.4K]

Answer: x>8

Step-by-step explanation: when we plug g(x) into f(x) we get sqrt7(1/x-8) and when you graph (as shown below) this you see that the graph has a vertical asymptote of 8 therefore the domain is x>8

If 3 people go to lunch and the bill was $30 and they all give $10 and the waitress comes back with the waitress comes back and
Kryger [21]

Answer

No missing money

Step-by-step explanation:

Original money given to the waiter = $30

Each person paid $10

The waitress comes back with the waitress comes back and said the bill is $25

They gave her $2 for the tip

if each got $1.00 back

Balance = $1.00 × 3

= $3.00

That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)

Each of them got $1.00 back

Total money spent = (cost of meal + tip) + balance of $3.00 given to them

= $27 + $3

= $30

Therefore, there is no missing $1.00
