Answer: $\tan^2 t$

Step-by-step explanation:

$\sin^{2} t+\cos^2 t=1 \implies 1-\cos^2 t=\sin^2 t\\\\\implies \frac{1-\cos^{2}t}{\cos ^2 t}=\frac{\sin ^2 t}{\cos^2 t}=\tan^2 t$

bulgar [2K]

<h3>Answer:</h3>

$\huge{\boxed{72}}$

<h3>Explanation:</h3>

First, find the total number of apples. $6*1200=7200$

Now, multiply this by the probability of picking a rotten apple, which is $\frac{1}{100}$ . This is also the same as dividing by $100$ , or moving the decimal point two places to the left. $7200*\frac{1}{100}=72$

This means that based on the probability given, $72$ rotten apples will be picked.

Which is bigger? 1.27 or 1 1/3?

uranmaximum [27]

11/3 is bigger 1.27 because when you do 11/3 you get 3.66666666666666666667 which is clearly bigger than 1.27 so like I said 11/3 is bigger than 1.27.

The perimeter of the kite is 134 cm. Find the value of x.

frez [133]

Answer:

x = 10 cm

Step-by-step explanation:

(3x + 2) + (3x + 2) + (4x - 5) + (4x - 5) = 134 cm

combine like terms:

14x - 6 = 134

add 6 to each side of the equation:

14x = 140

divide both sides by 14:

x = 10

Composition function rule (f○g)(x) = f(g(x))
<em><u /></em><u>Given the separate functions</u>: $f(x)=2x+1$ and $g(x)=x^2$

$(f\circ g)(-5)\rightarrow\text{ Composition Function Rule}\rightarrow f(g(-5))=2((5)^2)+1$
$\rightarrow2(25)+1=50+1=51$
