We want to find the moon's gravitational acceleration.

With the given information, we will see that the gravitational acceleration on the moon is: g = 1.625 m/s^2

We know that in a place with a gravitation acceleration g, if you drop something from a height H, the position equation of that object will be given by:

p(t) = (-g/2)*t^2 + H

In this case, we know that a feather falls 81.25cm in one second.

First, we can define H = 0 (because we can put the zero of the position where we want to)

Then if after one second the feather falls 81.25cm = 0.8125 meters, we need to solve:

p(1s) = -0.8125 m = (-g/2)*(1s)^2

Where the negative sign comes because the feather "falls" and we define the negative position as below.

Also notice that we did a change of units from centimeters to meters, by knowing that:

100cm = 1m

then:

81.25cm = 0.8125m

Now we just need to solve:

-0.8125 m = (-g/2)*(1s)^2

0.8125 m = (g/2)*(1s)^2

2*0.8125 m = (g)*1s^2

1.625 m = g*1s^2

(1.625 m)/(1 s^2) = g

We then can conclude that the moon's gravitational acceleration is:

g = 1.625 m/s^2

11,05

Step-by-step explanation:

11 1/20

= (11 × 20 + 1)/20

= (220 + 1)/20

= 221/20 → times 5

= 1105/100

= 11,05

Answer:

11.05

Step-by-step explanation:

To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.

In this case, the value of x would be 5 because 20 × 5 = 100.

Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:

[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]

5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.

The line appears to intersect the origin (0,0) and (2.5,12.5).

Slope is rise over run, so if you take the difference in y value and divide it by the difference in x value, you get the slope.

     5x becomes 5(2) which is 5 times 2 = 10

17)

    (4x) + 7 becomes (4 times 2) + 7 = 15

21)

    (2x) + (2y) becomes (2 times 2) + (2 times 3)

Step-by-step explanation:

If we rewrite each term of the sequence to a common denominator then it makes it easier to see the pattern:

       ³/₂ , ²/₃ , ⁻¹/₆, -1 , ___

      ⁹/₆ , ⁴/₆ , ⁻¹/₆ , ⁻⁶/₆ , ___

This makes the pattern Xₙ = ⁹/₆ - ⁵⁽ⁿ⁻¹⁾/₆

∴ the missing term is ⁻¹¹/₆

Answer:

= 10 R 22

= 10 22/34

= 10 11/17

Step-by-step explanation:

Answer:

steps below

Step-by-step explanation:

1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator       (-3a) / 2 = 5 / 4

-12a = 10

a = - 5/6

2) 3-n > n+ 10  ... degree of the denominator < degree of the numerator

   2n < -7

   n < - 3.5

The largest inter value is -4

3) f(x) = (x²+3x-4) / (2x²+7x-10)

   f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2

   x->∞ : divide x² both numerator and denominator, any number/ x -> 0

   f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2

   [tex]\lim_{x \to \infty} f(x) = f(2)[/tex] = 1/2

1 hr = 3600 s

Convert:

[tex]\frac{3.2 x 10^5 gal}{1 sec} * \frac{3600 sec}{1 hr}[/tex]
