Answer:
The costs of the plan are $0.15 per minute and a monthly fee of $39
Step-by-step explanation:
Let
x ----> the number of minutes used
y ----> is the total cost
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to

we have the ordered pairs
(100,54) and (660, 138)
substitute


step 2
Find the equation of the line in point slope form

we have

substitute

step 3
Convert to slope intercept form
Isolate the variable y

therefore
The costs of the plan are $0.15 per minute and a monthly fee of $39
Using a graph tool
see the attached figure
the answer is the option
<span>a 90° clockwise rotation</span>
Answer:
2 roots.
Step-by-step explanation:
The roots are the same things as the x-intercepts. From -4 to 3, there are two times when the polynomial intersects the x-axis. So, there are 2 roots.
Hope this helps!
Answer:
c) is the correct one
Step-by-step explanation:
a) Is not true in the case of a videogame, because the outcome of your strategy depends on what your opponent does, therefore, your strategy effectiveness might depend on mind games and execution. Unintuitively, knowing all possible cases doesnt give you a good representation of reality.
b) Maybe the researcher experiment involves goats, but a doubt that the video game relates with goats at all.
c) After you experiment multiple times with anything, you may obtain concrete deductions on what is happening according on the results you obtain from those experiments.
