3days=3chapters so he would have to read for 8 days
Answer:
There isn't one.
Step-by-step explanation:
The square root of a negative number is imaginary. There is no real number that is the square root of -3.24.
Try graphing y=x^3. It crosses the x-axis at (0,0), and this point represents the one and only real root.
Every form of a cubic function has a graph that crosses the x-axis in 1 or 3 places.
Thus, the correct answers to this particular problem are B and C.
Additionally, certain cubic function forms have graphs that cross the x-axis in one unique place, but which touch (but do not cross) the x-axis. Here you have one unique real root plus one repeated (duplicated) real root, for a total of 3 roots.
Using these facts, decide which of the four given answers are correct.
Answer:
14i^2
Step-by-step explanation:
Answer:
300tan43 - 300tan40
Step-by-step explanation:
Use tangent to find the height of the building:
tan40 = b/300
b = 300tan40
The use tangent to find the height to the top of the antenna:
tan43 = a/300
a = 300tan43
The antenna height = a - b
