What to the 2nd power equal 9/16

Mathematics
1 answer:
MAXImum [283]3 years ago
7 0

Answer:

\pm{\frac{3}{4}}  to the 2nd power equals  \frac{9}{16}

Step-by-step explanation:

Let the unknown number which is raised to 2nd power be = x

So, the expression can be written as:

x^2=\frac{9}{16}

Solving for x

Taking square root both sides to remove the 2nd power.

\sqrt{x^2}=\pm\sqrt{\frac{9}{16}}

x=\pm\sqrt{\frac{9}{16}}

Since 9 and 16 are perfect square, we can write them in 2nd powers of 3 and 4 respectively.

x=\pm\sqrt{\frac{3^2}{4^2}}

∴ x=\pm{\frac{3}{4}}

fredd [130]

Answer:

Option C, 1225

Step-by-step explanation:

y=4.009x-77.531

selling 325 pizzas, so x=325, now putting the value of x in the equation,

y=4.009×325-77.531

or, y=1225.394

y = 1225.394, which is the profit, if we approximate it to the nearest value, it's $1225
