Answer:
Option C
Step-by-step explanation:
WE are given a graph of exponential function and asked to find out of four functions which function the graph represents.
We find that any function of the form
passes through (0,1) for all a
Hence we cannot distinguish any thing from the point
Let us consider when x=1
Then first function will have point as (1,2.4)
II funciton (1,0.31)
III function (1,0.45)
IV funciton (1,1.8)
From the graph given we find that the point of y is less than 1. Hence it can be either II or III
Consider x=-1
Then II function has point as (-1,3.225) and III function has point as (-1,2.222)
From the graph we find that the graph satsified only the point (-1,2.2222)
Hence OPtion III is right
Answer:
Arrow C.
Step-by-step explanation:
Out of three arrows, nearest arrow from the origin will be the best arrow.
Ordered pair for arrow A → (-5, 4)
Distance between A and bullseye = 
= 
= 
= 6.40 units
Ordered pair for arrow B → (5, -5)
Distance between B and bullseye = 
= 
= 7.1 units
Ordered pair for arrow C → (-2, -6)
Distance between C and the bullseye = 
= 
= 6.32 units
Distance between C and the bullseye is the shortest.
Therefore, arrow C will be the best arrow.
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
Answer:
-2.5 = x
Step-by-step explanation:
Multiply by what's in the parentheses by 2.
6x - 1 = 4x - 6
Add 6 to both sides of equation.
6x + 5 = 4x
Subtract 6x from both sides.
5 = -2x
Divide both sides by -2.
-2.5 = x
Ok so for C. yes you can change the mode and median but not the mean. You can do so because depending on where the coins land it can change the mode and the median can be different because the number are mixed meaning the numbers could have more larger or smaller numbers. Ok now for part D. Yes you can on purpose because you can always change the numbers to equal a reasonable median. In doing so you may change the mode though.
