Answer:

Fuel efficient vehicles

Step-by-step explanation:

Since energy costs began increasing in 1970s, a major shift in building practices is the use of more Fuel efficient vehicles. In the 1970s the rise in the cost of energy made most vehicle users to start using smaller vehicles instead of Larger vehicles because smaller cars consume less energy. the effect of this shift caused a structural unemployment in the car manufacturing industry

Find the first derivative?

professor190 [17]

You could do the question the way it is written, but it is far easier to bring the negative power up to the numerator.

y= x^2 - 3. The derivative of that is
dy/dx = 2x The three is a constant and is always dropped when a derivative is taken
d(-3)/dx = 0

If you are a purist and want to solve the question the way it is written, you could do it this way.

dy/dx = d(1)/dx x^-2 - d(x^-2)/dx * 1
======================
(x^-2)^2

dy/dx = - (-2 x^ - 3) / x^-4

dy/dx = 2 x^-3 * x^4
dy/dx = 2 x^(-3 + 4)
dy/dx = 2x ^ 1
dy/dx = 2x <<<<< answer

What does this equal <br>32p = 160

Assoli18 [71]

You should divide each side by 32. Then when you divide the 160 from 32 you should get 5. Because 32x5 =160

Polygon abcd is rotated 90 degrees counterclockwise about the orgin to create polygon a b c d , match each set of cordinates to

mihalych1998 [28]

Answer:

A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, translation and dilation.

Rotation is the turning of an object about a point. If a point A(x, y) is rotated 90 degrees counterclockwise about the origin, the new point would be A'(-y, x)

From the image attached, the coordinates of polygon ABCD is A(1, 1), B(1, 2), C(2, 2), D(3, 1). If polygon ABCD is rotated 90 degrees counterclockwise about the origin, the new vertices would be at A'(-1, 1), B'(-2, 1), C'(-2, 2) and D'(-1, 3).
