What is more important, π or e? Why?
Svetradugi [14.3K]
Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.

Hope this helps, have a great day.

Line L is Parallel to Line M. Find the value of x and y (pls help asap)
LenaWriter [7]

Answer:

x = 9 and y = 13

Step-by-step explanation:

10x - 17 and 8x + 1 are Alternate Exterior angles so they equal the same.

So we are going make them equal each other.

10x - 17 = 8x + 1 ( plus 17 on both sides)

10x = 8x + 18 (subtract 8x on both sides)

2x = 18 (divide by 2)

x = 9

PLUG IN 8(9) + 1 = 73 so...

6y + 29 + 73 = 180  (two angle next to each other have to equal 180)

6y + 102 = 180 ( subtract 102 on both sides)

6y = 68 (divide by 6 on both sides)

y = 13

PLUG IN

6(13) + 29 = 107

53 pts!! The function f(x)= 7^x+1 is transformed to function g through a horizontal compression by a factor of 3. What is the eq
e-lub [12.9K]

The value of k will be 3 if the function is transformed by compression factor of 3

Step-by-step explanation:

The horizontal stretch or compression for a function f(x) is given by  g = f(bx) where b is a constant. If b> 0 then the graph of function is compressed.

As it is given in the question that he function is transformed by a compression factor of 3.

Given function

f(x) = 7^x+1\\To\ transform\\g = f(bx)\\g = 7^{3x}+1

The value of k will be 3 if the function is transformed by compression factor of 3
