We have

\left(\dfrac{2}{3}\right)^x=\dfrac{2^x}{3^x}

And we want

\dfrac{2^x}{3^x}=\dfrac{16}{81}=\dfrac{2^4}{3^4}

Another way to read it is

\dfrac{16}{81}=\left(\dfrac{2}{3}\right)^4=\left(\dfrac{2}{3}\right)^x

It should be clear that the solution is x=4

Answer:

16 / 81 = 0.1975308642

2 / 3 = .6666666666666

.6666666666666^x = 0.1975308642

Taking logs of both sides:

x * log (.6666666666) = log (0.1975308642)

x = log (0.1975308642) / log (.6666666666)

x = -0.7043650362  / -0.1760912591

x = 4

Answer:

Horizontal component = 9.6

Step-by-step explanation:

Recall that the horizontal component is given by the cosine projection;

v_x=|v_0| * cos(\theta)

which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:

v_x=12.6 * cos(40.5^o)=9.5811

And rounding to the nearest tenth as requested, we have:

v_x=9.6

Which fractions are equivalent to 4/6? Select all that apply.
kiruha [24]

Answer:

2/3

8/12

Step-by-step explanation:

You just divide each numerator 4 (5÷4) and each denominator by 6 (8÷6) and see if the numbers are the same.

5÷4=1.25

8÷6=1.33

They are not equivalent, so 5/8 is not correct

2÷4=0.5

3÷6=0.5

They are equivalent, so 2/3 is correct
