1 hour = 60 minutes/300 minutes (set up a ratio problem)
5 hours
Answer:
a) The domain is the set of the possible values of x.
In the graph, we can see that x goes from - 4 to 4
So the domain is: D = x∈ {-4, 4)
b) The zeros are the points where the graph cuts the x-axis.
Those values are:
x = -2
x = 0
x = 2.
c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.
in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.
in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.
in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
General formula of the parabola in vertex form is
f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.
f(x) = (x + 5)²- 28
h= -5, k = -28,
so (-5, -28) is a vertex of the given parabola.
Answer is A.
Answer:
(cos π/4, sin π/4) or approx. (0.707, 0.707)
Step-by-step explanation:
The length of the blue ray is 1. That's the same for any ray drawn inside the circle.
Then a = cos π/4 and b = sin π/4.
The cartesian coordinates of the point (a, b) are
(cos π/4, sin π/4) or approx. (0.707, 0.707)
Step-by-step explanation:
<em>6 x 10 ^ 5 = 600,000</em>
<em>2 x 10 ^ 3 = 2,000</em>
<em>You can either subtract 600,000 and 2,000 (598,000) or if you mean by exponents, then 10 ^ 1.</em>
