The shaded area = the arced area - the area of the triangle

The arced area = (120/360) * pi * 6^2 = 12pi

The height of the triangle is 6*sin60 = 3√3

So the area of the triangle is 1/2 * 6 * 3√3 = 9√3

So the shaded area = 12pi - 9√3

Which equation is the inverse of y = 100 – x2?

sdas [7]

Answer:

Step-by-step explanation:

$\tt\displaystyle y = 100 - x^2\to\{y = x\}\\\\x = 100 - y^2\to\\\\y^2 = 100 - x\to\\\\y = \pm\sqrt{100 - x}$

If Shane’s average number of jumps completed is greater than one-half, then the

Norma-Jean [14]

Ok so, it all depends if Shane is likely to jump win over all of the other seventh graders then the eighth graders should earn the 50 points...

But if the roles are reversed the the Seventh graders should earn the 50 points.

There is not a full answer to what I am saying but from speculation you should be able to decide..

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft

neonofarm [45]

We develop an equation for the given situation by first writing the general equation for lines,

y = mx + b

Substituting to this given the values given above,

(1990) 430 = b

(2000) 400 = m(10) + 430

The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,

y = -3x + 430
