At which value will the graph of y=tanx have a zero? Please explain the correct answer!
Rina8888 [55]

Answer: None of the above are correct.


Step-by-step explanation:

Given function: y=\tan x

We know that the value of tan x =0 at x=0.

Also, At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{3}=\sqrt{3}

At\ x=\frac{\pi}{2},\ \tan\frac{\pi}{2}=\infty

At\ x=\frac{\pi}{3},\ \tan\frac{\pi}{4}=1

Hence, the only option is correct is "None of the above are correct".

A new shopping mall is gaining in popularity every day since it open the number of shoppers is 20% more than the numbers of shop
erastovalidia [21]

Answer: the number of shoppers on the first day is 125

Step-by-step explanation:

The number of shoppers is 20% more than the numbers of shoppers the day before. It means that the number of shoppers is increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of term in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

r = 1 + 20/100 = 1.2

n = 4(first 4 days)

S4 = 671

Therefore, the expression for the first 4 days is

671 = (a × 1.2^(4) - 1)/1.2 - 1

671 = (a × 1.2^(4) - 1)/0.2

671 = 1.0736a/0.2

671 = 5.368a

a = 671/5.368

a = 125

Solve for a please show all your work
o-na [289]
Z = -b - a + 1

subtract 1
1z - 1 = -1b - 1a ( 1z is the same as z, same goes for b and a)

add -1b
1b - 1z - 1 = -1a

then we remove -1 by dividing it.
-1b -(-1z) + 1

Answer: -1b -(-1z) + 1 = A

A negative minus a negative is a positive, so the answer might as well be....
-1b + 1z + 1 = A
