Answer:

It passes through the point (3,4). Given that the center of the circle is the point (0,0). We know that the equation of the circle is given by : (x-a)^2 + (y-b)^2 = r^2 where (a,b) is the center and r is the radius.

77. Use properties of exponents to explain why it makes sense to define 16 *1/4 as √16 4 .

skelet666 [1.2K]

Answer and explanation:

Given : Expression $(16)^{\frac{1}{4}}$ as $\sqrt[4]{16}$

To find : Use properties of exponents to explain why it makes sense to define expression ?

Solution :

Using property of exponent,

$x^{\frac{1}{n}}=\sqrt[n]{x}$

On comparing with given expression,

Here x=16 and n=4

$(16)^{\frac{1}{4}}=\sqrt[4]{16}$

Hence by property it defied the expression.

PLs help me on this..........

Serggg [28]

Answer:

247277 people

Step-by-step explanation:

6% of 243,000 = 14,580

243,000 + 14,580 = 257,580

4% of 257,580 = 10,303.2

Estimating 10,303.2 to 10,303

257,580 - 10,303 = 247277

A box contains 6 black pens, 4 blue pens, and 7 red pens. Without looking, Clarissa randomly picks a black pen out of the box. I

Irina18 [472]

Answer:

31.35%

Step-by-step explanation:

<h3>Initial reading:</h3>

In the box, there are:

6 Black pens
4 blue pens
7 red pens

Total number of pens in the box = 6 + 4 + 7

= 17

If we count pens as outcomes the total number of possible outcomes are 17.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>New reading:</h3>

Clarissa takes out a black pen from the box.

That reduces the number of black pens by 1 which increases the total number of pens by 1 as well.

So now:

Number of black pens = 6 - 1 = 5 
Total number of pens = 17 - 1 = 16

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Probability:</h3>

$\boxed{ \mathsf{probability = \frac{favorable \: outcomes}{total \: outcomes} }}$

If we want her to pick up a black pen, and she ends up picking one. So, we can say that the outcome is in our favor.

That makes it,

the number of favorable outcomes = number of black pens

= 5

and total outcomes = Total number of pens

= 16

$\implies\mathsf{probability = \frac{5}{16} }$

For showing it as some percent we'll just multiply the fraction by 100

$\implies \mathsf{ \frac{5}{16} \times 100 }$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>As a percent:</h3>

$\implies \mathsf{ \underline{ 31.25 \: \% } }$
