Answer:
D No. as there are only 12 bolts longer than 1inch.
Mr. Slivka needs 16 bolts of greater than 1 measure, and there are only 12.
Step-by-step explanation:
We cannot include 1 inch data as this is not over 1 inch like the 1inch 2/8 and 1inch 4/8 etc. the greater measures of over 1 inch count to 12.
We know they are greater as they do not have a negative sign next to the added fraction of 1 2/8 or 1 4/8.
Here, the focus of the parabola is (2,0) and directrix is x=−2.
So, equation of parabola will be y2=4ax
Here,a=2.So, Equation becomes,
y2=4∗2x⇒y2=8x, which is the required equation of parabola.

Answer:
the first one
Step-by-step explanation:
magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
