A2. Find y' and y" for y^2 = x^2<br>+ sinxy

kumpel [21]

Answer:

y' = (2x + y cosxy)/(2y + x cosxy)

Step-by-step explanation:

Using implicit differentiation:

y^2 = x^2 + sin xy

2y y' = 2x + cos xy * (xy' + y)

2y y' = 2x + xy' cos xy + y cos xy

2y y' - xy' cosxy = 2x + ycos xy

y' = (2x + y cosxy)/(2y - x cosxy)

I need help with C, thank you.

Simple....

$\frac{3}{4} x\ \textless \ \frac{9}{2}$

x<6

This means that on your graph at 6 it's a circle (not colored in) and it goes to the left indefinitely...

Thus, your answer.

Answer:

See below

Step-by-step explanation:

<u>Given functions</u>

f(x)=8^x
g(x)=8^(x+5) + 1

As we see g(x) = f(x + 5) + 1, which means <u>horizontal translation 5 units left</u> and <u>vertical translation 1 unit up</u>.

Point D(-3.5) is a vertex of triangle DEF.After a rotation of the triangle about the origin, D' is located at (3,-5).Which of th

Nimfa-mama [501]

<h3>Answer: 180 degrees</h3>

note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.

========================================

Explanation:

The rule for 180 degree rotations is

(x,y) ---> (-x, -y)

So the x and y coordinates flip in sign from positive to negative, or vice versa.

Point D ' (-3, 5) rotates to D ' (3, -5) following this rule

-----------------

A further detailed break down might look like this

x = -3 becomes -x = -(-3) = 3

y = 5 becomes -y = -5

(-3, 5) ----> (3, -5)
