Answer:
? = 7.2
Step-by-step explanation:
Remark
Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.
Formula
a^2 + b^2 = c^2
Givens
c = 12
a = 9.6
b = ?
Solution
c^2 - a^2 = b^2
144 - 92.16 = b^2
b^2 = 51.84 Take the square root of both sides
sqrt(b^2) = sqrt(51.84)
b = 7.2
when does it hit the ground? check the picture below.
at that moment, the velocity is -32(3).
The correct answer is B. Reflection across the line y = -x followed by a rotation 180° counterclockwise about the origin.
Factors of -48 that add up to 2
-6 and 8
So these are the factors (x + 8)(x - 6)
If you have any of those as th option, it is the answer.
Since it is a vector of <1090,0> from the red car and a vector of <0,790> from the blue car, adding them up gets a vector of <1090,790>, resulting in a final point of (1090, 790)
Hope this helps!
