The flag pole is 
or write it as 
tall.
Step-by-step Explanation:
Let "p" be the height of the flag pole.
The ratio of the child height to the pole height is the same as the ratios of their respective shadows, so,
Now, Cross multiply :-
→ 
→ 
→ 
This 
can be rounded off to 
as it ends with 
So, the flag pole is <u>9 metres</u> tall.
Answer:
The First one is discrete data;the second one is continuous data
You have to estimate the slope of the tangent line to the graph at <em>t</em> = 10 s. To do that, you can use points on the graph very close to <em>t</em> = 10 s, essentially applying the mean value theorem.
The MVT says that for some time <em>t</em> between two fixed instances <em>a</em> and <em>b</em>, one can guarantee that the slope of the secant line through (<em>a</em>, <em>v(a)</em> ) and (<em>b</em>, <em>v(b)</em> ) is equal to the slope of the tangent line through <em>t</em>. In this case, this would be saying that the <em>instantaneous</em> acceleration at <em>t</em> = 10 s is approximately equal to the <em>average</em> acceleration over some interval surrounding <em>t</em> = 10 s. The smaller the interval, the better the approximation.
For instance, the plot suggests that the velocity at <em>t</em> = 9 s is nearly 45 m/s, while the velocity at <em>t</em> = 11 s is nearly 47 m/s. Then the average acceleration over this interval is
(47 m/s - 45 m/s) / (11 s - 9 s) = (2 m/s) / (2 s) = 1 m/s²
Answer:
put -2 in -2 / put -2 again in same spot and again just do it for 3 times then 1/3 in the middle of 0 and -2 but a bit closer to the -2
Step-by-step explanation:
Answer:
14x-56y-42
Step-by-step explanation:
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
14x-56y-42
Hence the equivalent expression is
14x-56y-42
