If the base is 4, what is the value if the exponent is 2? What if the exponent is -2?

Vikentia [17]

Answer:

In the world of exponents, 4 is the number being raised by the exponent, which is 2.

Let's answer the first question:

If the base is 4, what is the value if the exponent is 2?

The base is 4 and the exponent is 2. We would multiply 4 two times.

$4^2= 4*4 = 16$

So, it would be 16.

Let's answer the second question:

What if the exponent is -2?

<u>This is the rule for negative exponents:</u>

$a^{-x}=\frac{1}{a^x}$

Using this rule, we can solve $4^{-2}$ .

$4^{-2}= \frac{1}{4^2}=\frac{1}{16}$

So, our answer for the 2nd question is 1/16.

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).

Helga [31]

Answer: $(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

Step-by-step explanation:

Point slope form: $(y-b)=n(x-a)$ , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through $(x_1,y_1)$ and $(x_2,y_2)$ :-

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

So, the equivalent equations are :

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

A tiger is 7/8 meter tall. A koala bear is 4/7 as tall as the tiger. A penguin is 7/8 as tall as the kaola bear. How tall is the

You just multiply them because “as” in the question means the same thing as “of” so it will be 7/16.

$a) \: \cos(39°) = \frac{x}{7} \Leftrightarrow x = 7\cos(39°) \approx5.44 \\ b) \: \sin(46°) = \frac{8}{x} \Leftrightarrow x = \frac{8}{\sin(46°)} \approx11.12$
