The equation for a circle's area is \pi r^2. and the equation for the diameter is 2\pi r . lets find r. we have 111.6=3.14*r^2. divide by 3.14 on both sides. that makes 36=r^2 take the square root of both sides. r=6.
now we find the diameter. 2\pi r=2*3.14*6=3.14*12 which is approximately 38.68

Given the function f(x) = -5x + 11 + 3, for what values of x is f(x) = -12?<br> Bleaseeeeee

Nitella [24]

Answer:

x = 5.2

Step-by-step explanation:

$f(x) = -5x + 11 + 3$

Let's first simplify our first function:

$f(x) = -5x + 11 + 3\\f(x) = -5x + 14$

Now, we just need to set this function equal to our other given function.

$f(x) = -5x+14\\f(x) = -12\\-5x + 14 = -12$

Now, we can add 12 to both sides:

$-5x + 14 + 12 = -12 + 12\\-5x + 26 = 0$

Now, add 5x to both sides:

$-5x+26 = 0\\26 = 5x\\$

Finally, we'll divide both sides by 5:

$26/5 = 5x / 5\\5.2 = x\\x = 5.2$

Answer: x = 5.2

Find x pretty please

Answer:

100⁰

because this is a quadrilateral inscribed in the circle

=> x + 80 = 180

<=> x = 180 - 80 = 100⁰

Solve for x. -3x 4 = -8

agasfer [191]

This question is false, there are no solutions, even if u take away the x and make it multiplication instead of a variable, still no solutions exist
