What's the best Approximation? :3
musickatia [10]
Area of shaded region = Area of larger circle - Area of smaller circle.

We know, Area of a Circle = πr²
So, A = πr₁² - πr₂²
A = π (r₁² - r₂²)
A = π(10.2² - 5.4²)
A = 3.14 (104.04 - 29.16)
A = 3.14 (74.88)
A = 235.12

In short, Your Answer would be 235.12 cm²

Hope this helps!

Which of te following statemnet are true
valkas [14]

Answer:

B

Step-by-step explanation:

Clearly BD is shorter than AE so that is false.

BD is clearly on the opposite end of EC so it is not bisecting, as bisecting would be DE bisecting AC

AC has to be perpendicular to something to be a perpendicular bisector however it is a straight line.

What is the x intercept of f(x)=x^2+7x+2? And how do you solve it?
Kitty [74]

Answer:

Since that is a quadratic equation, it will have 2 "x" intercepts.

x^2+7x+2

a = 1   b = 7   c = 2

You would solve for "x" using the quadratic formula.

x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a

x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1

x = [ -7 +- sq root (49 -8) ] / 2

x1 = [-7 + 6.4031242] / 2

x1 =  -.29844

x2 = [-7 - 6.4031242] / 2

x2 = -6.7016
