Answer:
Well where are the options for the graphs?
Answer:
<em>The correct option is: 32.4 km/h</em>
Step-by-step explanation:
The fastest recorded speed of a turtle while swimming is 9 m/s.
Now, 9 m/s 
1 kilometer= 1000 meter
So, 1 meter 
kilometer
and <u>9 meters</u> 
kilometer
Now, 1 hour = 3600 seconds
So, <u>1 second</u> 
Thus, we will get.........
So, the speed of the turtle will be 32.4 km/h.
Step-by-step explanation:
4.5 s, 324 ft
Explanation:
The object is projected upward with an initial velocity of
v_0 = 144 ft/sv
0
=144ft/s
The equation that describes its height at time t is
s(t) = -16t^2 + 144 ts(t)=−16t
2
+144t (1)
where t, the time, is measured in seconds.
In order to find the time it takes for the object to reach the maximum height, we must find an expression for its velocity at time t, which can be found by calculating the derivative of the position, s(t):
v(t) = s'(t) = -32t +144v(t)=s
′
(t)=−32t+144 (2)
At the maximum heigth, the vertical velocity is zero:
v(t) = 0
Substituting into the equation above, we find the corresponding time at which the object reaches the maximum height:
\begin{gathered}0=-32t+144\\t=\frac{144}{32}=4.5 s\end{gathered}
0=−32t+144
t=
32
144
=4.5s
And by substituting this value into eq.(1), we also find the maximum height:
s(t) = -16(4.5)^2+144(4.5)=324 fts(t)=−16(4.5)
2
+144(4.5)=324ft
<h3>used this way i even don't know sorry:))</h3>
Answer:
The correct answer would be C = 533,800
Step-by-step explanation:
The formula for circumference is C = 2πr. To find the radius you must divide the diameter by 2.
Radius = 85000
now we have C = 2 * 85000 * 3.14
C = 533,800
<em>Scientific Formula = 5.338 x 10^6</em>
