Express secΦ in terms of tanΦ​
Sunny_sXe [5.5K]

Answer:

\sec\theta=\sqrt{1+\tan^2\theta}

Step-by-step explanation:

The trigonometric identity is :

\sec^2\theta-\tan^2\theta=1\\\\or\\\\\sec^2\theta=1+\tan^2\theta

We need to express secθ in terms of tanθ.

The above equation becomes,

\sec\theta=\sqrt{1+\tan^2\theta}

Hence, this is the required solution.

Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of th
Lapatulllka [165]

Answer:

\frac{3}{5}th part of the bottle will be drunk by the calf.

Step-by-step explanation:

Part of the bottle fed by the piglet = \frac{1}{5}

Milk left in the bottle = 1 - \frac{1}{5}

                                  = \frac{5-1}{5}

                                  = \frac{4}{5}

Milk drunk by the calf = \frac{3}{4}th of the left part

                                     = \frac{3}{4}\times \frac{4}{5}

                                     = \frac{3}{5}th part of the bottle

Therefore, \frac{3}{5}th part of the bottle will be drunk by the calf.

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

(\frac{2^1(2)^3}{4}^2)\\\\= (\frac{\frac{2(2^3)}{2} }{4})^2 \\\\= (\frac{1(2^3)}{4}) ^2\\\\= ( \frac{(1)(8)}{4} )^2\\\\= (\frac{8}{4})^2\\ \\= 2^2\\= 4

So the answer is : = 4
