Answer:
x=20
Step-by-step explanation:
inverse operation
add 7 to both sides
x=20
Answer:
"As the x-values go to positive infinity, the function's values go to positive infinity."
Step-by-step explanation:
End-Behavior of a fucntion is basically what happens to the function when x goes to positive infinity and when x goes to negative infinity.
In this function, we can say:
- as we move to the right (x increases), the value of the function (y-value) increases towards positive infinity.
- Also,
- as we move to the left (x decreases), the value of the function (y-value) decreases towards negative infinity.
From the answer choices, we take the last one -- "As the x-values go to positive infinity, the function's values go to positive infinity."
* Note, this is a cubic function
Answer:
3 * 10^6 if the answer is 3.64 * 10^6, you really ought to argue the meaning of estimate with your instructor.
Step-by-step explanation:
This is a very valuable question. Put your calculator away when you answer it. Using a calculator is sort of cheating.
1.3 * 10^3 roughly is roughly 1 * 10^3
2.8*10^3 hours is roughly 3 * 10^3
Forget the powers for now and just work with the 1 and 3
1*3 equals 3.
10^3 * 10^3 = 10^6 when the base of two numbers is the same (10 in this case) then the powers are added.
10^(3 + 3) = 10^6
So the answer is roughly 3*10^6
Now you can take out your calculator and get the answer.
1.3*10^3 * 2.8 * 10^3 = 3.64 * 10 ^ 6
Notice that the estimate (done in my head) is close enough to tell you what the answer should be. On a test, that's a very handy skill.
To convert this you divide the speed by 60 since there's 60 minutes in an hour
125/60 = 2.0833....
Since you round the answer would be
2.1 miles per minute
<span>s=1/2at^2
2s = at^2
t^2 = 2s/a
t = + square root (2s/a) and </span>t = - square root (2s/a)
or
+ square root (2sa)
t = ------------------------------
a
and
- square root (2sa)
t = ------------------------------
a
