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
