Answer:

  85°

Step-by-step explanation:

Each of the isosceles triangles PAB and QBC has interior base angles of ...

  (180° -80°)/2 = 50°

Then angle PBC is 90° -50° = 40°.

Segments PB and QB are the same length, so triangle PBQ is an isosceles right triangle. This means angle BPQ is 45°. Angle QEB is the sum of the remote interior angles of ∆BEP, so is 45° +40° = 85°.

The acute angle between PQ and BC is 85°.

Parabola passes through the points (0,5), (1,4), and (2,5). What function does the graph represent?
AfilCa [17]

Answer:

x^2 - 2x + 5 = 0.

Step-by-step explanation:

The (0, 5) is the point where the parabola passes through the y axis (where x = 0), so we can write the equation as

y = ax^2 + bx + 5   where a and b are constants to be found.

Also, since (1, 4) and (2, 5) are points on the curve, substituting, we have the system:

a(1)^2 + 1b + 5 = 4

a(2)^2 + 2b + 5 = 5

Simplify these 2 equations:

a  + b  =  -1  .................(1)

4a + 2b = 0..................(2)

Multiply the first equation by -2:

-2a - 2b = 2 .................(3)

Add (2) + (3):

2a = 2

a = 1.

Substitute a = 1 into (2):-

4*1 + 2b = 0

2b = -4

b = -2.

Other than on a coordinate grid, how else can you describe the location of a point or object? Is one way better than the other?
KIM [24]

Answer:

Understanding a concept like the coordinate plane often means putting the abstract terminology and descriptions into a real-world setting. Mathematics describes the real world, but often it isn’t clear how the concepts translate to real life. Coordinate planes range from being abstract representations of other variables to spatial coordinates that are easy to find real-world examples of. To use a coordinate plane in real life, simply choose what type of system you’re going to use and define the directions they go in. However, you need to consider a few more complicated ideas to get the most out of it.
