A non-negative number is a number which is either zero or a positive number

For numerical example , to satisfy rule \sqrt[k]{a^{m} } =(\sqrt[k]{a} )^{m} substitute a = 16, m = 2 and k = 2

The square root of a number is the number that we need to multiply by itself to get the original number

Now substituting, a = 16, m = 2 and k = 2 in given rule

            \sqrt[2]{16^{2} } =(\sqrt[2]{16} )^{2} \\\\\sqrt[2]{16*16}=\sqrt[2]{16}*  \sqrt[2]{16}\\\\16=16

So,  \sqrt[2]{16^{2} } satisfy the given rule.

Gulf gully and jump rope road are a pretty far distance.If the scale for the map is 0.5 inches=2.3 miles,what is the actual dist
Nezavi [6.7K]

Answer:

12 cm = 21.62 miles

6 cm = 11.04 miles

Step-by-step explanation:

To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of \frac{map}{real world} and simplify.

We know \frac{map}{real world}=\frac{0.5in}{2.3 miles}. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write \frac{4.7in}{xmiles} and  \frac{2.4in}{xmiles}

We set them equal.

\frac{0.5}{2.3}=\frac{4.7}{x}

and

\frac{0.5}{2.3}=\frac{2.4}{x}

To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

2.3(4.7)=0.5(x)\\10.81=0.5x\\\frac{10.81}{0.5}=\frac{0.5x}{0.5} \\21.62 miles=x

and

2.3(2.4)=0.5(x)\\5.52=0.5x\\\frac{5.52}{0.5}=\frac{0.5x}{0.5} \\11.04 miles=x

If p(x)=x^2+x+1 and q(x)=3x^2-1, find p(7)
Delvig [45]

Answer:

p(7) = 57

Step-by-step explanation:

Because this is a function, all you have to do is input 7 for x like so:

p(x)=x^2+x+1 --------------->     p(7)=7^2+7+1

                                            so 49 + 8

                                                = 57
