Absolute value is simply the non-negative version of the number regardless of its symbol

So for the absolute value of 20? the answer is just 20.

For reference, the absolute value of -20 is also just 20.

Hope the explanation helps :)

Answer:

20

Step-by-step explanation: The absolute value is the distance from zero. Meaning, the absolute value always has to be positive. if you had |-20|, the absolute value would be 20 because from zero, the distance is 20.

xenn [34]

Answer:

23

Step-by-step explanation:

find 10% = 4

quadruple it = 16

half 10% = 2

half it again = 1

2.5% = 1

40% = 16

1 + 16 = 17

take 17 off of 40 = 23

What are the x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2π? (1 point) a x = 3 p
Ratling [72]

x-coordinates for the maximum points in any  function  f(x) by f'(x) =0 would be  x = π/2 and x= 3π/2.

<h3>How to obtain the maximum value of a function?</h3>

To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

we want to find x-coordinates for the maximum points in any  function  f(x) by f'(x) =0

Given f(x)= 4cos(2x -π)

f'(x) = 0\\- 4sin(2x -\pi ) =0\\\\sin (2x -\pi ) =0 \\2x -\pi  = k\pi ...  k in Z

In general  x=(k+1)\pi /2

from x = 0 to x = 2π :

when k =0  then  x = π/2

when k =1  then x= π

when k =2  then x= 3π/2

when k =3  then x=2π

Thus, X-coordinates of maximum points are  x = π/2 and x= 3π/2

The Zigzag River is 114 miles longer than twice the Petite River. If the Petite River is 46 miles long, how long is the Zigzag R
emmasim [6.3K]
Z = 114 + 2p
p = 46

Plug in 46 for 'p' in the first equation.

z = 114 + 2p

z = 114 + 2(46)

Multiply:

z = 114 + 92

Add:

z = 206

So the Zigzag river is 206 miles long.
