Help! Look at the photo provided!
lara [203]

Answer:

It's the first choice.

Step-by-step explanation:

The first term is the value of n / (2n +1) when n = 1

So first term = 1 (2 + 1) = 1/3

Second term = 2/(2(2) + 1) = 2/5

Third term = 3 / (3(2) + 1) = 3/7  and so on.

Please help with this word problem<br> thanks

When  a jogger runs south and then turns west, we have right angle between segment 0.8 mi and segment to the west. So it is legs of the right triangle.
1.7 mi is hypotenuse.

hypotenuse² =(leg1)²+(leg2)²
1.7²=0.8² + (leg2)²
(leg2)²=1.7²-0.8² = 2.25 mi²
leg2=√(2.25 mi²)
leg2=1.5 mi
Answer is 1.5 mi.
