Answer:
2(20-64)
Step-by-step explanation:
4*10-64*2
40-128
2(20-64)
0.668 is the greatest.
If you have trouble because they have different place values, you can just and a "0" and the end of the decimals and they will still have the same value. Just make sure to change it back before writing your final answer.
Answer:
37,400
Step-by-step explanation:
Whatever the number 10 is being squared by, you just move the decimal right if it is a positive number. In this case, it is 10 to the 4th power.
If you move the decimal in 3.74 four times to the right, you will get 37,400.
Answer:
y = (x + 1)(x - 0.586) ( x - 3.414)
Step-by-step explanation:
I sure wouldn't recommend doing this by trial and error.
I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.
y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2
are the listed roots.
The square root is
y = (x + 1)(x - 0.586) ( x - 3.414)
Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2
you get 4 just as you should. Amazing that we have tools that do that sort of thing.
Answer:
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
Step-by-step explanation:
In simple terms, the domain of a graphed function refers to all the possible x-values while the range refers to all the possible y-values. Therefore, based on the graph the answer would be.
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
This is because x is in a slope and extends infinitely both to the left and to the right, therefore having all possible values. The y-axis starts at and includes the value 2 and all values less than 2. A black filled in dot in a graph indicates that the value is included.
