Answer:
1.5 for how far he ran in 4 seconds
Step-by-step explanation:
Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.
Let x be the height of the flagpole, then
![\sin50^o= \frac{x}{5}](https://tex.z-dn.net/?f=%5Csin50%5Eo%3D%20%5Cfrac%7Bx%7D%7B5%7D%20)
Therefore, the <span>equation that could be used to find the height of the flagpole is
</span><span>x/5 = sin 50</span>
Step-by-step explanation:
X1 = 1
X2 = (X1) 2 - X1
X2 = 2 - 1
X2 = 1. implies that the second term of the sequence is 1.
Step 1
<u>Find the total area</u>
Total area=(1,150,000/18,075)=63.62 square kilometer
The area of a circle is equal to
![A=\pi * r^{2} \\ 63.62= \pi * r^{2}\\r=\sqrt{(63.62/\pi)} \\r=4.5\ km](https://tex.z-dn.net/?f=%20A%3D%5Cpi%20%2A%20r%5E%7B2%7D%20%5C%5C%2063.62%3D%20%5Cpi%20%2A%20r%5E%7B2%7D%5C%5Cr%3D%5Csqrt%7B%2863.62%2F%5Cpi%29%7D%20%5C%5Cr%3D4.5%5C%20km%20)
therefore
the answer is
![4.5\ km](https://tex.z-dn.net/?f=%204.5%5C%20km%20)
