Answer:
x ∈ {-0.465, 1.014}
Step-by-step explanation:
The equation can be cast in the form f(x) = 0, and solved easily using a graphing calculator. That shows x ≈ -0.465 and x ≈ 1.014. The same calculator can iterate the roots to full calculator precision.
__
The equation can be made a quadratic by the substitution ...
z = e^(2x)
Then we have ...
Answer:
its the one on the bottom
Step-by-step explanation:
We are trying to find the number that when added to 19, gives us less than 42. We can set up this simple inequality:
19 + x < 42
Now, subtract 19 from both sides:
x < 23
Our number can be anything less than 23.
The answer is 10. because median means middle so 10 is the middle #.
By the looks of it the hieght is 7 and base is 6 so
A= 1/2(6)(7)
A= 1/2(42)
A= 21
