Answer: 102.9 m

<u>Step-by-step explanation:</u>

First, use Pythagorean to find the length of AC

AB² + AD² = AC²

50² + 80² = AC²

2500 + 6400 = AC²

8900 = AC²

94.34 = AC

Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.

94.34 - 15 = 79.34

Next, find the circumference of the circle

C = πd

C = 15π

They are only walking around 1/2 of the circle so divide it by 2.

(1/2)C = (15/2)π

≈ 23.56

Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.

79.34 + 23.56 = 102.9

Carbon dioxide comprises approximately what percentage of the atmosphere

In-s [12.5K]

The Carbon Dioxide in the atmosphere is only very small relative to other gases. Typically, it only consists about 0.038 percent or 0.04 percent of the gases in the atmosphere.

<span>
Even though it is only small, CO2 is very important since it is one of the greenhouse gases which ensures that the Earth stays warm.</span>

Rewrite in polar form: x^2+y^2-2y=7

Alchen [17]

X²+y²-2y=7
using the formula that links Cartesian to Polar coordinates
x=rcosθ and y=r sin θ
substituting into our expression we get:
(r cos θ)²+(r sin θ)²-2rsinθ=7
expanding the brackets we obtain:
r²cos²θ+r²sin²θ=7+2rsinθ
r²(cos²θ+sin²θ)=7+2rsinθ
using trigonometric identity:
cos²θ+sin²θ=1
thus
r²=2rsinθ+7
Answer: r²=2rsinθ+7
