Answer:

0.00324 or in scientific notation  3.24×10^-3

Step-by-step explanation:

MASS OF SINGLE ELECTRON = 5.4×10^-4

MASS OF 6 ELECTRONS = 6× 5.4×10^-4

                                           =32.4×10^-4

                                            = 3.24×10×10^-4

                                             = 3.24×10^-3

Graph - 9x + 6y = 18 using linear standard form
postnew [5]

Answer:

The graph is attached Below and the plotting is given below.

Step-by-step explanation:

Given:

-9x + 6y = 18

Solution:

To draw a line on a graph the required minimum two points but here we will have three points as point A, point B, and point C.

For point A

Put x = -4 in the given equation we get

-9×-4 + 6y = 18

6y = 18-36

∴ y=\frac{-18}{3}\\ \\y=-3

∴ Point A ≡ ( -4, -3 ).

For point B

Put x = -2 in the given equation we get

-9×-2 + 6y = 18

6y = 18 - 18

6y = 0

∴ y=\frac{0}{3}\\ \\y=0

∴ Point B ≡ ( -2, 0 ).

For point C

Put x = 0 in the given equation we get

-9×0 + 6y = 18

6y = 18

∴ y=\frac{18}{3}\\ \\y=3

∴ Point C ≡ ( 0, 3 ).

Now we have Point A ,B and C join it and you will have Line.

Let V be the volume of the solid obtained by rotating about the y-axis the region bounded y = 25x and y = x2 25 . Find V by slic
vesna_86 [32]

Answer:

volume\ = \pi \frac{625^2}{6}

Step-by-step explanation:

See the attached figure.

y₁ = 25x  and  y₂ =x²

The intersection between y₁ and y₂

25x = x²

x² - 25x = 0

x(x-25) = 0

x = 0 or x =25

y = 0 or y =25² = 625

The points of intersection (0,0) and (25,625)

To find the volume of the solid obtained by rotating about the y-axis the region bounded by y₁ and y₂

y₁ = 25x ⇒ x₁ = y/25 ⇒ x₁² = y²/625

y₂ =x² ⇒ x₂ = √y ⇒ x₂² = y

v = ∫A(y) dy = π ∫ (x₂² - x₁²) dy

∴ V =

\pi \int\limits^{625}_0 {y-\frac{y^2}{625} } \, dy  =\pi( \frac{y^2}{2} -\frac{y^3}{3*625} ) =\pi (\frac{625^2}{2} -\frac{625^3}{3*625}) =\pi ( \frac{625^2}{2}-\frac{625^2}{3}) =\pi \frac{625^2}{6}

The Pep Club will sell chocolate and strawberry popsicles at a football game. They need to buy at least 200 popsicles. Chocolate
Andru [333]

The inequality that represents this equation is 8x + 30y ≥ 200

<h3>Inequality</h3>

Inequality is an expression used to show the non equal comparison of two or more variables and numbers.

Let x represent the number of chocolate popsicles and y represent the number of strawberry popsicles.

Chocolate popsicles are sold in packs of 8. Strawberry popsicles are sold in packs of 30. Since they need at least 200 popsicles:

8x + 30y ≥ 200

The inequality that represents this equation is 8x + 30y ≥ 200

State the amplitude and period of f(x)= -3 sin t
Sphinxa [80]

Answer:

The period is 2\pi and the amplitude is 3.

Step-by-step explanation:

The period goes from one peak to the next (or from any point to the next matching point). The amplitude is the height from the center line to the peak.

The period of the function y=a\sin (bx) is T=\dfrac{2\pi }{b} and the amplitude is |a|.

Consider the function f(t)=-3\sin t.

The period for the function f(t) is

T=\dfrac{2\pi}{1}=2\pi

and the amplitude is 3.
