a basketball player attempted 15 baskets in the game he makes 9 of the attempted baskets which ratio describes the number of bas

goldenfox [79]

Answer:

3:5

Step-by-step explanation:

We are given that

Basket player attempted basket=15

He makes number of attempted basket=9

We have to find the ratio which describes the number of baskets the player made to the number of baskets to play attempted.

$\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{9}{15}$

$\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{3}{5}$

Hence, the ration which describes the number of baskets the player made to the number of baskets to play attempted=3:5

Which expression is equivalent to (1−sinβ)(1+sinβ)/cos2β for all values of β for which (1−sinβ)(1+sinβ)/cos2β is defined?

stealth61 [152]

<h3>Answer: Choice E) 1</h3>

Work Shown:

$\frac{(1-\sin(\beta))(1+\sin(\beta))}{\cos^2(\beta)}\\\\\frac{1-\sin^2(\beta)}{\cos^2(\beta)}\\\\\frac{\cos^2(\beta)}{\cos^2(\beta)}\\\\1\\\\$

Therefore, $\frac{(1-\sin(\beta))(1+\sin(\beta))}{\cos^2(\beta)}=1\\\\$ is an identity for all values of β for which the original expression is defined. I used the difference of squares rule for the 2nd step. Then I applied the pythagorean trig identity for the 3rd step.
