x + 33° = 180° (It's forming a linear pair that's why the sum is 180°.)
x = 180° - 33°
x = 147°
Answer:
t = .64sec and t = 1.56sec
Step-by-step explanation:
This is motion that is modeled by a parabola. The nature of a parabola is symmtrical about some vetical line. That means that if there is an x value where y = 3, for example, when the object is traveling upwards, it will come down after it reaches its max height and be at that same y = 3 height, just at a later time. By this, I mean that you will have 2 times where the height is 7. Besides that, this is a second degree polynomial, so we are expecting 2 values of t.
We are asked to find these 2 times when the height, h, is 7. So we will fill in a 7 for h and factor to solve for t:
To factor this quadratic, we need to get everything on one side of the equals sign and set it equal to 0:
Factor this however your teacher has instructed you to factor quadratics (my guess is that you're probably using the quadratic formula) to get t values of:
t = .64 sec and t = 1.56 sec
Answer:
all work is pictured and shown
B.
I think B will make more B make more sense because you say he gets 75 a week.
Answer:
X'(6,-5)
Y'(7,1)
Z'(4,0)
Step-by-step explanation:
First, the reflection across the x-axis. The rule for reflection across the x-axis is:
(x,y) -> (x,-y)
Next the translation. This is easy, simply add 9 to all x values, and 2 to all y values.
