Tanya is training a turtle for a turtle race. For every 1/3 of an hour that the turtle is crawling, he can travel 2/23 of a mile
Oxana [17]

The unit rate with the turtle crawling is 6/23 mile per hour.

According to the statement

we have given that the every 1/3 of an hour that the turtle is crawling, he can travel 2/23 of a mile. and

we have to find the unit rate with the turtle crawling

So, For this purpose,

we know that the

The unit rate of speed in miles per hour the number of miles in one hour.

So, to find the unit rate:

Divide distance in miles with the time which is in hours.

So,

unit rate of speed = distance / time

unit rate of speed = (2/23) / (1/3)

unit rate of speed = 6/23 mile per hour.

So, The unit rate with the turtle crawling is 6/23 mile per hour.

Ya'll fr get 50 points if you answer this. <br> What is the rate of change of <img src="https://tex.z-dn.net/?f=f%28x%29%3D2%5Ex
Evgesh-ka [11]

Answer:

\dfrac{dy}{dx}=2^x\ln 2

Step-by-step explanation:

**This is a non-linear function and therefore <u>does not have a constant rate of change</u>.  It will have a different slope depending on what points you use in the average rate of change formula:\mathsf{average \ rate \ of \ change = \dfrac{change \ in \ y}{change \ in \ x}}

To calculate rate of change, differentiate.

substitute y for f(x):  

\implies y=2^x

Take natural logs of both sides:

\implies \ln y=\ln 2^x

Apply the log rule  \ln a^b=b \ln a :

\implies \ln y=x\ln 2

Differentiate with respect to x:

\implies \dfrac{1}{y} \frac{dy}{dx}=\ln 2

Mulitply both sides by y:

\implies \dfrac{dy}{dx}=y\ln 2

Replace y with y=2^x

\implies \dfrac{dy}{dx}=2^x\ln 2

Therefore, rate of change of the function is :

\dfrac{dy}{dx}=2^x\ln 2

What is the volume of the regular pyramid?
ad-work [718]

Answer:

C

Step-by-step explanation:

The volume of the regular pyramid is V=\dfrac{1}{3}A_{base}H.

The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.

Hence, the volume of the pyramid is

V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.
