The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?
siniylev [52]

Answer:

A.

Step-by-step explanation:

Anwer A has the following equation:

g(x)=\frac{3}{5}x^2-3

In this equation, we can calculated the intercept replacing x by 0, as:

g(x)=\frac{3}{5}0^2-3=-3

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.

Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

0=\frac{3}{5}x^2-3\\x_1=\sqrt{5}=2.236\\x_2=-\sqrt{5}=-2.236

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.

So, the answer is A, g(x)=\frac{3}{5}x^2-3

The radius of a circular sign is 12 inches. Equal parts of the sign are painted red and yellow. How many square inches are paint
AnnZ [28]

Answer:

226.08 square inches

Step-by-step explanation:

Area of a circle is given by

A=\pi r^{2}

Where r is the radius and r is the area.

For this case, since one half is painted yellow and another red, then the area for each paint will be given by

A=0.5\pi r^{2}

Substituting 12 inches for r then

A=0.5\pi 12^{2}=226.08 in^{2}

Therefore, each paint occupies approximately 226.08 square inches
