Answer:
18.852
Step-by-step explanation:
Formula to find the arc of semi circle is :
Arc length = π r
Given that,
diameter ⇒ 12
So, the radius will be,
Radius ⇒ 12 / 2
⇒ 6
<u>Let us solve now.</u>
Arc length = π r
= 3.142 × 6
=<u> 18. 852</u>
Hello from MrBillDoesMath!
Answer:
The fourth choice, b = +\- sqrt( sg + a^2)
Discussion:
s = (b^2 - a^2)/g => multiply both sides by "g"
sg = b^2 - a^2 => add a^2 to both sides
sg + a^2 = b^2 => take the square root of each side
b = +\- sqrt( sg + a^2)
which is the fourth choice.
Thank you,
MrB
Answer: Tina rides 4 miles and Derek rides 3 miles.
Explanation:
Since we have given that
Distance covered by Derek in west direction be x
Distance covered by Tina in south direction be x+1
Distance between the bikers when they both stop is x+2
Since it forms right triangle, so we will apply "Pythagorus theorem":
![H^2=P^2+B^2\\\\(x+2)^2=x^2+(x+1)^2\\\\x^2+4x+4=x^2+x^2+1+2x\\\\x^2+4x+4=2x^2+2x+1\\\\x^2-2x^2+4x-2x+4-1=0\\\\-x^2+2x+3=0\\\\x^2-2x-3=0\\\\x^2-3x+x-3=0\\\\x(x-3)+1(x-3)=0\\\\(x+1)(x-3)=0\\\\x=-1,3](https://tex.z-dn.net/?f=H%5E2%3DP%5E2%2BB%5E2%5C%5C%5C%5C%28x%2B2%29%5E2%3Dx%5E2%2B%28x%2B1%29%5E2%5C%5C%5C%5Cx%5E2%2B4x%2B4%3Dx%5E2%2Bx%5E2%2B1%2B2x%5C%5C%5C%5Cx%5E2%2B4x%2B4%3D2x%5E2%2B2x%2B1%5C%5C%5C%5Cx%5E2-2x%5E2%2B4x-2x%2B4-1%3D0%5C%5C%5C%5C-x%5E2%2B2x%2B3%3D0%5C%5C%5C%5Cx%5E2-2x-3%3D0%5C%5C%5C%5Cx%5E2-3x%2Bx-3%3D0%5C%5C%5C%5Cx%28x-3%29%2B1%28x-3%29%3D0%5C%5C%5C%5C%28x%2B1%29%28x-3%29%3D0%5C%5C%5C%5Cx%3D-1%2C3)
Since distance can't be in negative sign, so we take x=3 miles
Derek rides 3 miles
Tina rides is given by
![x+1=3+1=4\ miles](https://tex.z-dn.net/?f=x%2B1%3D3%2B1%3D4%5C%20miles)
Hence, Tina rides 4 miles and Derek rides 3 miles.
