Answer:
y = -5
Step-by-step explanation:
2y - 10y + 30 = 70
-8y + 30 = 70
-8y = 70 - 30
-8y = 40
y= -5
Answer:
sin A = 40/41
tan A = 40/9
cos A = 9/41
Step-by-step explanation:
sin theta = opp/ hyp
tan theta = opp/ adj
cos theta = adj/ hyp
We want to find the measures for angle A
sin A = 40/41
tan A = 40/9
cos A = 9/41
Area of a cirlce=πr²
we have two radius:2r and r
area of the cirlce₁ + area of the circle₂=80 m²
area of the circle₁=π(2r)²
area of the circle₂=πr²
Then, we can suggest this quation:
π(2r)²+πr²=80
4πr²+πr²=80
π(4r²+r²)=80
π(5r²)=80
5πr²=80
r²=80/5π
r=√(80/5π)≈2.26
radius of the largest cirlce=2r=2(2.26)=4.51
Answer: the radius of the largest circle is 4.51 m
Answer:
the other x intercept would be -0.6
Step-by-step explanation:
Answer:
Octagon
Step-by-step explanation:
Formula for a polygon is :
- a = apothem (distance from center to the midpoint of a side
- P = perimeter (sum length of the sides)
Since a regular octagon has 8 sides, and a regular hexagon has 6, the octagon will have the greater area due to greater perimeter.
