The logarithmic expression ln(√e/y^3) can be rewritten as
kvv77 [185]

Answer:

\dfrac{1 - 6 \ln y}{2}

Step-by-step explanation:

\ln \dfrac{\sqrt{e}}{y^3} =

= \ln \dfrac{e^\frac{1}{2}}{y^3}

= \ln e^\frac{1}{2} - \ln y^3

= \dfrac{1}{2} \ln e - 3 \ln y

= \dfrac{1}{2} - 3 \ln y

= \dfrac{1 - 6 \ln y}{2}

SMART PEOPLES HELP ME ASAP
inysia [295]

Answer:

35 degrees

Step-by-step explanation:

The angle is given to be a right angle by the red square. The right angle is intercepted by a line. One side of the whole 90 degree angle is said to be 55 degrees. Both sides should equal 90 degrees if added.

This means that to find the missing angle, you would subtract 55 degrees from 90 degrees to get 25 degrees.

If x and y vary directly, and x=10 when y=3, what will be the value of x when y=9?
Thepotemich [5.8K]

As x and y vary directly then <span>x∝y</span> i.e. <span>x=ky</span>, where k is a constant.

When <span>x=24</span>, <span>y=8</span> i.e. <span>24=k×8</span> and therefore

<span>k=<span>248</span>=3</span>

and relation between x and y is hence <span>x=3y</span>

and when <span>y=9</span>, <span>x=3×9=27</span>.



I hope this is what you're looking for.

Which equation represents a proportional relationship that has a constant of proportionality equal to –10?
aksik [14]

Answer:

y = - 10x

Step-by-step explanation:

The equation representing a proportional relationship is

y = kx ← k is the constant of proportionality

y = - 10x ← is the only equation in this form

Thus the equation is y = - 10x with k = - 10
