The answer is C, 18 buses.
60 minutes = 1 hour. 60 divided by 10 = 6. 6 x 3 = 18.
Classifying pairs of angles...
Vertical Angles
Vertical angles are formed by two intersecting lines. They are a pair of angles that are across from one another and always have the same degree measurement.
Adjacent Angles
Adjacent angles are a pair of angles that share a side and a vertex but do not overlap.
Complementary angles
Complementary angles are a pair of angles that add up to 90o. Placing complementary angles together forms a right angle.
Supplementary angles
Supplementary angles are a pair of angles that add up to 180o. Placing supplementary angles together forms a straight line.
Corresponding angles
Corresponding angles are formed when a pair of parallel lines is
intersected by a third line (also called a transversal line). They are a
pair of angles that are at corresponding positions but are not adjacent
angles. Corresponding angles are on the same side of the transversal
line and always have the same degree measurement.
Alternate Interior Angles
Alternate interior angles are formed when there exists a transversal. They are the
angles on opposite sides of the transversal, but inside the two lines the transversal
intersects. Alternate interior angles are congruent to each other if (and only if)
the two lines intersected by the transversal are parallel.
An easy way of identifying alternate interior angles is by drawing the letter "Z"
(forwards and backwards) on the lines as shown below.
Alternate Exterior AnglesSimilar to alternate interior angles, alternate exterior angles are also congruent
to each other if (and only if) the two lines intersected by the transversal are
parallel. These angles are on opposite sides of the transversal, but outside the
two lines the transversal intersects.
The arrow are pointing to the right, so the numbers on the left are inout values (X) and the numbers on the right are output numbers (Y)
-3 points to 4 so you have (-3,4)
-1 points to 5 for (-1,5)
0 points to 7 for (0,7)
2 points to 2 for (2,2)
5 points to 7 for (5,7)
The 3rd answer has all these combinations.
Please use " ^ " to indicate exponentiation: F(x) = 5 + 3x − x^2. One way to determine the range of a quadratic function, such as this function is, is to find the vertex. The y-value of the vertex is the max or the min of the function.
In this case, we have f(x) = -x^2 + 3x + 5, and the associated coefficients are a = -1, b = 3 and c = 5. The axis of symmetry is x = -b/[2a].
Here, the equation of the axis of symmetry is x = -3/[2*-1), or x = 3/2.
Find the corresponding y value by subbing 3/2 for x in f(x) = -x^2 + 3x + 5:
f(3/2) = -(3/2)^2 + 3(3/2) + 5 = -9/4 + 9/2 + 20/4, or 9./4.
Thus, the vertex, representing a maximum, is (3/2, 29/4).
The range is (-infinity, 29/4].
