y/x = k
6.4/4 = 1.6
11.2 / 7 =1.6
16/10 = 1.6
20.8 /13 =1.6
This is a direct variation and the constant is 1.6
y=1.6x

Answer:
10.4 to nearest tenth.
Step-by-step explanation:
If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.
Altitude of each triangle = sqrt(2^2 - 1^2)
= sqrt3.
So the area of 1 triangle = 1/2 * 2 * sqrt3
= sqrt3
Therefore the area of the hexagon = 6 * sqrt3
= 6sqrt3
= 10.3923
ANSWER:
A. -11x^2
EXPLANATION:
-x^2 + -10x^2 = -11x^2
Hope it helps u!
With respect to the given angle of 40°
AC = b, is the opposite side
AB = 10 in is the hypotenuse.
Using the rules of trigonometric ratios,
We know the ratio associating opposite & hypotenuse is sin.
So we have
Substituting the values we get
Multiplying both sides by 10 we get
b = 10 sin 40°
So
AC = 10 sin40°
First option is the right answer.
