Algebra I Quadratics Review Guide for test 5/24

There will be a unit test (the last one!) on Friday.  It is very comprehensive of the whole unit; in other words, there is a lot of graphing and vocab on the test and  not just solving equations.

There are 8 questions, though some will have multiple parts.

5 Solving quadratic equations - you can use any method.  All will have real solutions.
6 on quadratic equation vocab -  vertex, roots, solutions, maximum/ minimum, parabola, standard form, quadratic equation, quadratic formula
1 graphing a quadratic
1 finding the vertex
1 putting a quadratic equation into standard form
1 reading a parabolic graph that matches a real world situation


Be able to:

solve:  (x+1)(x - 5) = 0

solve: x^2 +8x +7 = y

solve:  x^2 - 2x = 5

solve:  2x^2 - 11x + 5 = 0

solve:  4x^2 - 14 = 18   (yes that is a 14 and not a 14x)

graph:  y= 2x^2 - 8x + 7

what is the maximum value of y = -3x^2 +18x + 1?

Put the following into standard form:  y = (2x+3)(x - 6) + 2

If a golf ball is hit and its height is modeled by h = -16t^2 + 48t, when does it hit the ground?


ANSWERS:

2. x = -1, -7
3.  x = 1 +/- sq rt 6
4. x = 0.5, 5
5. x = +/- sq rt 8

vector/trig test review guide

The test for vectors is next Thursday 5/16/19.  There is some trigonometry on it as well.

The test is 8 questions, though like the last quiz there could be a and b parts to a few questions.


1 real world problem that will involve an oblique triangle.

2 drawing resultants after adding vectors (could involve scalar multiplication).
1 determining if a value is scalar or vector
1 putting a vector in component form and determining magnitude

1 naming coterminal angles
1 naming reference angles
1 where you're given 1 trig function ratio and are asked to find another
3 using right triangle trig or pythag or triangle sum to find missing info
4 finding the exact value of trig value at an angle (ex.  sine 60 dgs = )
1 solving a basic trig equation ( sin x = 1/2)
1 trig application involving angle of depression/ elevation (think planes landing)
2 involving the Pythagorean Identities
2  proving a mathematical truth using trig identities (prove: (tan x) (cos x) =  sin x
1 trig application on using a 2 variable equation (think a bouncy spring)
