Answer:
Step-by-step explanation:
we are given two temperature
4 degrees and -10 degrees
since it says to figure out the changed
substract
remove parentheses and change its sign
simplify addition:
and we are done!
The derivative of a function, found by using the power rule, is a graph with roots (x-intercepts) that are the same as the x-coordinates of the turning points of the said function;
This means that since the graph f(x) in the question shows us that the x-coordinates of the two turning points (A and B) are -2 and 6, we can determine that:
f'(x) = n(x + 2)(x - 6)
because if this was set to 0, the solutions would be x = -2 and x = 6;
The variable n represents the constant that could very well be 1 but we cannot assume so because of the limited information given;
This variable n would not change the solutions, but it will different for two functions that are the same in almost every respect (i.e. they will have the same x-coordinates of their turning points and roots) except that one is more vertically stretched than the other.
In any case, all you need to worry about for this question is drawing a u-shaped curve that crosses the x-axis at -2 and 6;
Don't worry about where it crosses the y-axis or how low it dips, just make all these things moderate as they cannot be deduced from the information given;
Its lowest point will be at x = 2 as the curve should be symmetric so just make sure the bottom of the curve is around that point.
Hope this helps.
1.
-2(a + 6) = -2 · a - 2 · 6 = -2a - 12
2.
-22:
whole numbers
rational numbers
integers
3.
6 · (b - p) = 6(b - p)
4.
[5(14 - 2)²]/2 = (5 · 12²)/2 = (5 · 144)/2 = 720/2 = 360
5.
u + xy
u = 18; x = 10; y = 8, subtitute
18 + 10 · 8 = 18 + 80 = 98
6.
A = 479 ft²;
a - length of a side
A = a²
therefore
a² = 479 ⇒ a = √479 ⇒ a ≈ 21.886 ⇒ 22 (ft)
7.
(7 + 5) + 4 · 13 - 2 = 12 + 52 - 2 = 64 - 2 = 62
