E2x-3=7  (multiply by ln e on both sides)
ln e of e=1
>>> 2x-3=ln 7
         x=(ln 7 + 3)/2
         x=2.47   (to 3 s.f)

Determine whether the relationship between the circumfrance of a circle and its diameter is a direct variation. If so, identify
kipiarov [429]

Answer:

The relationship between the circumference of a circle and its diameter represent  a direct variation and the constant of proportionality is equal to the constant \pi

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx

where K is the constant of proportionality

In this problem we know that

The circumference of a circle is equal to

C=\pi D

therefore

the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant \pi

Really need to someone to break this down so I can understand it
djyliett [7]

Answer:

<u>Slope</u><u> </u><u>is</u><u> </u><u>4</u><u>/</u><u>3</u>

Step-by-step explanation:

Slope is the derivative of the equation:

y =  \frac{1}{3}  {x}^{2}  - 2x + 15 \\  \\  \frac{dy}{dx}  =  \frac{1}{3} (2x) - 2 + 0 \\  \\  \frac{dy}{dx}  =  \frac{2}{3} x - 2

At point (5, 7), x is 5:

\frac{dy}{dx}  =  (\frac{2}{3}  \times 5) - 2 \\  \\  \frac{dy}{dx}  =  \frac{10}{3}  - 2 \\  \\  \frac{dy}{dx}  =  \frac{10 - 6}{3}  \\    \\  \frac{dy}{dx}  =  \frac{4}{3}

It takes Evelyn, traveling at 36 mph, 45 minutes longer to go a certain distance than it takes Ricky traveling at 72 mph. Find t
navik [9.2K]
  • The distance travelled by both Evelyn and Ricky is 45 miles

If Speed = dist/time, then;

<u>dist = speed * time</u>

<u />

We also know that both of them travel the same distance, so we equate the distance travelled to each other

36 * x+45 = 72 * x

36x + 1620 = 72x

72x - 36x = 1620

36x = 1620

x = 1620/36

<u>x = 45 miles</u>

<u />
