Answer:

Stereo Pair

Step-by-step explanation:

Basically, a stereo-pair image contains two views of a scene side by side. One of the views is intended for the left eye and the other for the right eye. These images are sometimes viewed with special equipment to direct each eye on to its intended target, but they are also often viewed without equipment.

Answer:

1 foot = 0.3048 meters

Step-by-step explanation:

1 foot = 12 inches

1 inch = 2.54 centimeters

1 foot = 12 * 2.54 = 30.48 centimeters

1 meter = 0.01 centimeters

1 foot = 0.3048 meters

Serhud [2]

You know that the length is 2 more than the width. If z is the width then y = z(z+2). I don't see the graph so you will have to scan and look for that y-z relationship.

Answer:

21. 3x^2 +7x

22. 6x^3 +3x

Step-by-step explanation:

21. The perimeter is the sum of the side lengths.

P = (x^2 +3x +1) +(4x -1) +(2x^2)

P = x^2(1 +2) +x(3 +4) +(1 -1) . . . . combine like terms

P = 3x^2 +7x

22. The area is the product of the dimensions.

A = (3x)(2x^2 +1)

A = 6x^3 +3x . . . . . use the distributive property

Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$l = 30 \ cm\\w = l\\\frac{dl}{dt} = 2 \ cm/h\\h = 20 \ cm\\\frac{dh}{dt} = 3 \ cm/h$

Step 2: Differentiate

Rewrite [VRP]: $V = l^2h$
Differentiate [Basic Power Rule]: $\frac{dV}{dt} = 2l\frac{dl}{dt} \frac{dh}{dt}$

Step 3: Solve for Rate

Substitute: $\frac{dV}{dt} = 2(30 \ cm)(2 \ cm/h)(3 \ cm/h)$
Multiply: $\frac{dV}{dt} = 360 \ cm^3/h$

Here this tells us that our volume is decreasing (ice melting) at a rate of 360 cm³ per hour.
