Answer:
148
Step-by-step explanation:
Average = sum of numbers /total numbers
let x = 5th number
123.2 = (118+ 128 + 124,+ 98 + x) / 5
123.2 = (468 + x) / 5
Multiply both sides by 5
616 = 468 + x
x = 148
Answer:
Distance: 12.04159458 or 12.0
Midpoint: (2.5, 1)
Step-by-step explanation:
I used the Distance and the Midpoint Formulas.
Answer:
First, a absolute value function is something like:
y = f(x) = IxI
remember how this work:
if x ≥ 0, IxI = x
if x ≤ 0, IxI = -x
Notice that I0I = 0.
And the range of this function is all the possible values of y.
For example for the parent function IxI, the range will be all the positive reals and the zero.
First, if A is the value of the vertex of the absolute function, then we know that A is the maximum or the minimum value of the function.
Now, if the arms of the graph open up, then we know that A is the minimum of the function, and the range will be:
y ≥ A
Or all the real values equal to or larger than A.
if the arms of the graph open downwards, then A is the maximum of the function, and we have that the range is:
y ≤ A
Or "All the real values equal to or smaller than A"
We can create two points.
30 feet below the surface of the water 10 seconds after he entered the water
100 feet below the surface after 40 seconds
So we have (10, 30) and (40, 100)
Plug this values into the slope formula:
m = y2-y1/x2-x1
m = (100 - 30)/(40 - 10)
m = 70/30
m = 2 1/3
