Use Desmos to graph all three absolute value functions on the same xy-plane.

The function y = |x| looks like the letter V where both lines meet at the origin.

I would recommend Desmos but |x| makes a parabola (which kinda looks like a V or U) and the number to the right would change where parabola is located on the graph. The point where it curves would be a y=1 and y=-2

Whats the mean for this data? round to 2 decimals places
kolbaska11 [484]

Answer:

1992.38

Step-by-step explanation:

The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.

Sum:

1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56

Divide:

There are 12 numbers, so divide 23908.56 by 12:

23908.56 / 12 = 1992.38

The average is thus 1992.38.

Point E is the midpoint of AB and point F is the midpoint of CD .
Gwar [14]

Answer:

# AB is bisected by CD

# AE = 1/2 AB

# CE + EF = FD

Step-by-step explanation:

* Lets talk about the mid point

- The mid-point of a segment is divided the segment into two

  equal parts

- The figure has line segment AB

- E is the mid-point of AB

∴ E divides the line segment AB into two equal parts

∴ AE = EB

∴ AE = 1/2 AB ⇒ (1)

- Any line passes through the point E will bisects the line segment AB

∴ AB is bisected by CD ⇒ (2)

∵ F is the mid-point of CD

∴ F divides the line segment CD into two equal parts

∴ CF = FD

∵ Point E lies on CF

∴ CE + EF = CF

∵ CF = FD

∴ CE + EF = FD ⇒ (3)

* There are three statements must be true (1) , (2) , (3)

# AB is bisected by CD

# AE = 1/2 AB

# CE + EF = FD

A rowing team rowing with the current traveled 36 km in 3 h. Rowing against the current, the team rowed 12 km in the same amount
alex41 [277]

Answer:

  • team: 8 kph
  • current: 4 kph

Step-by-step explanation:

The downstream speed is ...

  speed = distance / time

  speed = 36 km/(3 h) = 12 km/h

The upstream speed is ...

  12 km/(3 h) = 4 km/h

__

If b and c represent the speeds of the boat and current, respectively, then we have ...

  b + c = 12

  b - c = 4

Adding these gives ...

  2b = 16

  b = 8

  c = b -4 = 4

The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
