Please find the equation of the circle (ignore what is entered).

The general standard equation for a circle with radius r centered at (h, k) is:

(x-h)^2+(y-k)^2=r^2

In this problem, since the circle is centered at the origin, the point (h, k) is (0, 0). So, substituting it:

\begin{gathered} (x-0)^2+(y-0)^2=r^2 \\ or \\ x^2+y^2=r^2 \end{gathered}

Now, it is only necessary to find the radius. It is given in the picture (x-axis) and it has a value of 8.

So, the equation is:

\begin{gathered} (x-0)^2+(y-0)^2=8^2 \\ or\text{ } \\ (x)^2+(y)^2=8^2 \end{gathered}

Answer:

3.36 cm

Step-by-step explanation:

from the passage before ; the figure of question is similar to the first figure in passage because those triangles have an each equal angle.

Therefore the ratio of side is equal ; 1/0.84=4/x

Solve equation will be x(1)=4(0.84) ; x=3.36 cm

Find a solution of the quadratic equation.6x squared + 7x + 2 =0
worty [1.4K]

Given the equation:

6x^2+7x+2=0

We will use the following rule to find the solution to the equation:

x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

From the given equation: a = 6, b = 7, c = 2

So,

\begin{gathered} x=\frac{-7\pm\sqrt[]{7^2-4\cdot6\cdot2}}{2\cdot6}=\frac{-7\pm\sqrt[]{1}}{12}=\frac{-7\pm1}{12} \\ x=\frac{-7-1}{12}=-\frac{8}{12}=-\frac{2}{3} \\ or,x=\frac{-7+1}{12}=-\frac{6}{12}=-\frac{1}{2} \end{gathered}

So, the answer will be option B) x = -1/2, -2/3
