X - y > 0
can be written as
x>y

Draw the graph of x = y which will be a line through the origin and at an angle of 45 degrees to the horizontal y axis

The points will be represented by a shaded area above the line.

The lateral surface area of cone A is exactly 1/2 the lateral surface area of the cylinder B.

Tcecarenko [31]

The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.

<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>

Lateral surface area of cone = πrl

Lateral surface area of cylinder = 2πrh

Lateral surface area of cone A = πrl = πrh

Lateral surface area of cylinder B = 2πrh

This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.

The answer is: A. True.

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.

Step-by-step explanation:

Let,

Cost of 1 dozen doughnuts = x

Cost of 1 dozen croissants = y

According to given statement;

7x+3y = 53 Eqn 1

x+5y = 35 Eqn 2

Multiplying Eqn 2 by 7

$77(x+5y = 35)\\x+35y=245\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(7x+35y)-(7x+3y)=245-53\\7x+35y-7x-3y=192\\32y=192$

Dividing both sides by 32

$\frac{32y}{32}=\frac{192}{32}\\y=6\\$

Putting y=6 in Eqn 2

$x+5(6)=35\\x+30=35\\x=35-30\\x=5$

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.

The measurement of the edge of a cube is measured to be 12 inches, with a possible error of 0.03 inch. Use differentials to appr

adoni [48]

Answer:

A) possible error = 12.992

Possible values for the volume [1715,007,1740.992]

B) possible error = 4.325

Possible values for the surface area [859,675,868,325]

Step-by-step explanation:

The volumen of a cube is the cube of the length of a side. Thus, the meassurement of the volume is 12³ = 1728 inches³. To calculate the error, lets call Y the real value of the length,

Y = X + e, where e is the error and X = 12.

Y³ = (X+e)³ = X³ + 3X²e + 3Xe² + e³

the error is 0.03 inches, so we have that

Y³ = X³ + 12.96+0.0324+ 0.000027 = X³+12.992427 = X³+12.992 (rounded to 3 decimal places).

Thus, the absolute possible error is Y³- X³ = 12.992, and the volume of the cube is contained in the interval [X³-12.992,X³+12.992] = [1715,007,1740.992]

B) The surface area is 6 X². With X meassured as 12, the surface area is meassured by 6*12² = 864.

To calculate the absolute error, we take Y = X+e, with X and e as before. We have

6 Y² = 6*(X+e)² = 6X²+12Xe+6e² = 6X²+4.32+0.0054 = 6X²+4.3254

Hence, the absolute error is bounded by 6Y²-6X² = 4.3254 rounded by 4.325, and the value of the surface area is contained in the interval [6X² -4.325, 6X²+4.325] = [859,675, 868,325]
