Answer:
sentence 2
Step-by-step explanation:
H^2 = P^2 + B^2
a. 6^2 = 2^2 + 3^2
36 = 4 + 9
36 = 13
Therefore this is not a Pythagorean triple
b.5^2 = 4^2 + 3^2
25 = 16 + 9
25 = 25
Therefore this is a phythagorean triple
9514 1404 393
Answer:
1. area DEF = 2π cm²
2. arc JK = 2π cm
Step-by-step explanation:
1. The area is given by ...
A = 1/2r²θ . . . . . where r is the radius and θ is the central angle in radians
Your sector has an area of ...
A = (1/2)(3 cm)²(80(π/180)) = (1/2)(9 cm²)(4/9π)
A = 2π cm²
__
2. The length of an arc is ...
s = rθ . . . . . . . where r is the radius and θ is the central angle in radians
s = (5 cm)(72(π/180)) = (5 cm)(2/5π)
s = 2π cm . . . arc length
_____
<em>Additional comment</em>
There are π radians in 180°, so an angle in degrees can be converted to an angle in radians by multiplying by π/180°. (The units of degrees cancel, leaving a pure number. "Radians" have no units.)
Hello!
Let's plug our x-value of 6 into each expression, evaluate our expression, and compare them using an inequality, which will be our answer.
9(4)-2(6)
36-12
24
2(9-6)
2(3)
6
As you can see, this gives us 24_6. As you can see, 24 is greater, so we will use the > inequality, giving us 24>6.
Therefore, our answer is B) >.
I hope this helps!
