Distribute: 5(2x + 3)

gtnhenbr [62]

Answer:
3(2x - 5) =

WHY?
Distributive property.
You should multiply the outer number to each of the values inside ( and ). So that's 3 multiplied by 2x and 3 multiplied by 5. That's 6x-15.

Select all of the expressions that are undefined. csc(0) sec(0) csc(pi/2) sec(pi/2) csc(pi) sec(pi)

Softa [21]

Answer:

The answer is "undefined, 1, undefined, undefined, and -1".

Step-by-step explanation:

Finding expression:

$i) \csc(0) = \ cosec 0^{\circ} \\\\= \frac{1}{sin 0^{\circ}}\\\\= \frac{1}{0} \ \\\\$ undefined

$ii) \csc (\frac{\pi}{2})\\\\= cosec \frac{\pi}{2}\\\\= cosec \ 90^{\circ}\\\\= \frac{1}{\sin \ 90^{\circ}}\\\\= \frac{1}{1} \\\\=1\\$

$iii) \sec \frac{\pi}{2} \\\\= sec \ 90^{\circ}\\\\= \frac{1}{\cos 90^{\circ}}\\\\= \frac{1}{0} \\$ undefined

$iv) \csc(pi)\\\\= \ cosec (180^{\circ})\\\\= \frac{1}{\sin 180^{\circ}}\\\\= \frac{1}{0}\\$ undefined

$v) sec (\pi) \\\\=\frac{1}{\cos 180^{\circ}}\\\\= \frac{1}{-1}\\\\= -1$

Why does the series not exist?

Ber [7]

Step-by-step explanation:

(7n − 5) / (2n + 5) approaches 7/2 as n approaches infinity. However, this is an alternating series. So the function is fluctuating between -7/2 and +7/2. So the limit does not exist.
