Answer:

(7a^2 + 8b^2 + 5ab) (7a^2 + 8b^2 - 5ab)

Step-by-step explanation:

Dado que ambos términos son cuadrados perfectos, puede factorizar utilizando la fórmula de la diferencia de cuadrados, a^2 - b^ 2 = (a + b) (a - b), donde a = 7a^2 + 8b^2 y b = 5ab.

English: Since both terms are perfect squares you can factor using the difference of squares formula, a^2 - b^2 = (a + b)(a - b), where a = 7a^2 + 8b^2 and b = 5ab.

Find the measure of angle Y. Round your answer to the nearest hundredth. (Please type the numerical answer only)

Sati [7]

Answer:

y = 11.54°

Step-by-step explanation:

Reference angle = y°

Opposite side length = 4

Hypotenuse = 20

Apply trigonometric function SOH:

$Sin(y) = \frac{Opp}{Hyp}$

$Sin(y) = \frac{4}{20}$

$Sin(y) = 0.2$

$y = Sin^{-1}(0.2)$

y = 11.536959° ≈ 11.54° (nearest hundredth)

Adventureland Amusement Park has a Ferris wheel with a diameter of 240 feet. How far would a person travel in one revolution of

UkoKoshka [18]

Answer:

3,600 ft

Step-by-step explanation:

so you would divide 240 in half and get 120 and then you would multiply 120 and 360 because the Ferris wheel is a circle and then you would divide by 12 because there is 12 inches in a foot and get your final answer 3,600 feet

a rectangular prism has a volume of 1374.28 cubic inches.The prism is 9.4 inches wide and 17.2 inches long.What is the height of

NISA [10]

The volume V of a prism can be found by:
The volume of a rectangular prism can be found through:
$V=lwh$
Where l is the length, w is the width, and h is the height.

The height can be found by rearranging the equation to:
$h= \frac{V}{wl}$

Take the volume (1374.28) and divide it by the length times the width (9.4*17.2=161.68).
1374.28/161.68= 8.5 inches is the height of the prism.

Find the work done by gas?

salantis [7]

The work done by the gas when the gas expands will be 567.65 ft-lb.

<h3>What is the work done for an isothermal process?</h3>

The Pressure is inversely proportional to the volume.

Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.

Then the work done by the gas will be

WD = P₁ V₁ ln (V₂ / V₁)

A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.

The gas expands to a volume of 3 cubic feet.

Then the work done by the gas will be

WD = 700 x 2 x ln (3/2)

WD = 1400 x 0.405

WD = 567.65 ft-lb

The work done by the gas when the gas expands will be 567.65 ft-lb.

More about the work done for isothermal process link is given below.
