What you must do in this case is to find the roots of the polynomial.
We have then:
x ^ 2 + 20x + 100 = 36
Rewriting:
x ^ 2 + 20x + 64 = 0
The values of the roots are:
x1 = -4
x2 = -16
Remember that the values of the roots are what make the polinome zero
Answer:
x1 = -4
x2 = -16
It is given that the mountain climber's change in elevation over an 8-hour period is −248 feet. Therefore, to find the average change in elevation per hour for that time period all that we need to do is divide the total change in elevation by the the time taken.
Therefore, average change=
feet
Therefore, the first option is the correct option.
Base from the given that <span>tan X =sin X / cos X. so the answer to the question what is tan ( 90 - A) is:
first let X = 90 - A
substituting from the given that
</span>tan X =sin X / cos X
tan ( 90 - A) = sin ( 90 - A) / cos ( 90 - A)
i hope this can help with your question. feel free to ask frther clarifications
