If you would like to solve the equation 9/11 = x/22, you can calculate this using the following steps:

9/11 = x/22 /*22
x = 9/11 * 22
x = 18

The correct result would be 18.

Please I need help it's really hard

I'd say angle A = angle B
arc tangent (angle B) = 150 / 555
arc tangent (angle B) = 0.2702702703 
angle B = 15.124 degrees

By the way 555 feet is the height of the Washington Monument.

-15.6 = -3.9r please include an explanation of how you got your answer :) thanks

Mumz [18]

Here is the equation:

$-15.6 = -3.9r$

Since both decimals are negative, the answer will be positive.

Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

$-15.6 \div -3.9 = -3.9r \div -3.9 \\ 4 = r$

r is equal to 4 → r = 4

Q ,# 13 Graph the function Y = - X + X ^2

GalinKa [24]

We have the following function that is a quadratic function:

$y=-x+x^2$

So the graph of this function is shown in the figure below. This is a parabola as you can see. The roots of this functions, that is, the x-intercepts are:

$y=-x+x^2 \\ y=x(x-1) \\ \\ x_{1}=0 \ and \ x_{2}=1$

As you can see in the figure. This function decreases from $(-\infty,0.5)$ and increases from $(0.5, \infty)$

Finally, another thing we can see from the graph is that the vertex is the point:

$V(0.5,-0.25)$
