7 0

Answer:

10/14 or about a 71% chance

Step-by-step explanation:

First you add up all of the players and you get 14. If, at random the coach picks a player, to find the chance that it is not a senior just add up all of the people that arent seniors. You then get a 10 out of 14 (about 71%) chance that the coach will pick somone that is not a senior. I hope this helps :)

Find the area of a regular octagon with an apothem length of 10 and a side length of 6.
Sauron [17]

Answer:

A = 240 units²

Step-by-step explanation:

the area (A) of a regular polygon is

A = \frac{1}{2} pa ( p is the perimeter and a the apothem )

here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then

A = \frac{1}{2} × 48 × 10 = 24 × 10 = 240 units²

What is the relationship between exponentials and logarithms? How can you use these to solve equations? Provide an example in yo
Sveta_85 [38]

Answer:

Exponentials and logarithms are inverses of each other.

Step-by-step explanation:

Exponentials and logarithms are inverses of each other.

For logarithmic function:

Domain = \left ( 0,\infty  \right ), Range = \left ( -\infty ,\infty  \right )

Vertical asymptote is y - axis.

x - intercept is (1,0)

For exponential function:

Domain = \left ( -\infty ,\infty  \right ), Range = \left ( 0,\infty  \right )

Horizontal asymptote is x - axis.

y- intercept is (0,1)

Both exponential and logarithmic functions are increasing.

For example:

Solve: \log x=\frac{\log 5+\log 3}{\log 3^2}

\log x=\frac{\log 5+\log 3}{\log 3^2}\\\log x=\frac{\log (5\times 3)}{2\log 3}\,\,\left \{ \because \log (ab)=\log a+\log b\,,\,\log a^b=b\log a \right \}\\=\frac{\log 15}{2\log 3}

\Rightarrow \log x=\frac{\log 15}{2\log 3}\\\Rightarrow x=e^{\frac{\log 15}{2\log 3}}\,\,\left \{ \because \log x=y\Rightarrow x=e^y \right \}

Please Help!!!!!! Me On These Questions!!!!!

Consecutive odd or even integers are of the form x, x+2.
So we have x(x+2) = 63, where Diane's age = x.

x²+2x = 63.
x² + 2x - 63 = 0
(x + 9)(x - 7) = 0
x = -9, or 7.

Since -9 is awfully young, we rule it out and say Diane's age is 7, and her sister is 9.
