Simplify the problem: Sin theta Sec Theta

kherson [118]

Answer:

$\tan \theta$

Step-by-step explanation:

We have to simplify the following expression as given by

$\sin \theta \times \sec \theta$

= $\frac{\sin \theta}{\cos \theta}$

= $\tan \theta$ ( Answer )

Because, we know that $\sec \theta =\frac{1}{\cos \theta}$ and $\tan \theta = \frac{\sin \theta}{\cos \theta}$

If we consider $\sin \theta = \frac{Perpendicular}{Hypotenuse}$ and $\sec \theta = \frac{Hypotenuse}{Base}$ ,

then $\sin \theta \times \sec \theta = \frac{Perpendicular}{Hypotenuse}\times \frac{Hypotenuse}{Base} = \frac{Perpendicular}{Base}= \tan \theta$

What is the inverse of the equation y=x²-4, x≤ 0

Lina20 [59]

The inverse of the equation y = x² - 4, x≤ 0 is $y = \sqrt{x + 4$

<h3>How to determine the inverse of the equation?</h3>

The equation is given as:

y = x² - 4, x≤ 0

Swap the x and y values

x = y² - 4

Add 4 to both sides

y² = x + 4

Take the square root of both sides

$y = \sqrt{x + 4$

Hence, the inverse of the equation y = x² - 4, x≤ 0 is $y = \sqrt{x + 4$

Miss white wants to buy 5 value meals at mels dinner what is a reasonable total for he purchase

bagirrra123 [75]

Answer:

Step-by-step explanation:

Here you're being asked to recall your own experience in paying for "value meals." How much have you paid per meal?

If each meal costs $6.50, then 5 would cost $13.00 before tax, and

(1.07)(5)($13.00), or $69.55 total.

Note that there's not just one possible total cost, and that we don't know much about this situation but must insert reasonable values, such as a $6.50 per meal unit cost and a 7% tax rate.
