Answer:

secant and cosecant have no zeroes.

Step-by-step explanation:

We have in total 6 trignometric functions as

sine, cosine, tangent, cosecant, secant, or cotangent.

Of these we have

sin is 0 for all multiples of pi

cosec = 1/sin  cannot be zero since sine value is always finite lies between -1 and 1.

Similarly sec = 1/cos  cannot be zero since cosine value is always finite lies between -1 and 1.

cotangent can be 0 for odd multiples of pi/2

Hence answer is only

secant and cosecant

1 1/2 = 3 /2

3 / 4 = 3 / 4

Multiply Across:

3 * 3 = 9

2 * 4 = 8

= 9 / 8

How many solutions are there to the equation below?<br> 8x + 47 = 8(x + 5)
qaws [65]

Answer:

there are 0 solutions to the equation

Step-by-step explanation:

To know how many solutions are in the problem, we have to solve for x and see what result we have left. According to the result, we will know how many solutions there are

8x + 47 = 8(x + 5)

8x + 47 = 8*x + 8*5

8x + 47 = 8x + 40

8x - 8x = 40 - 47

0 = -7

As we can see we are left with an equality that is not fulfilled, this means that there is no solution to the problem, at least in the field of real numbers
