If two objects travel through space along two different curves, it's often important to know whether they will collide. (Will a

missile hit its moving target? Will two aircraft collide?) The curves might intersect, but we need to know whether the objects are in the same position at the same time. Suppose the trajectories of two particles are given by the vector functions for t 0. Do the particles collide? If they collide find t. If not enter NONE.
r1(t) = t^2, 8t − 15, t^2
r2(t) = 11t − 30, t^2, 13t − 40

Answer:

Step-by-step explanation:

r_1(t) = < t^2 , 8t-15,t^2> \\ \\ r_2(t) = < 11t-30, \ t^2 , \  13t-40>  \\ \\  at \  r_1 = r_2 \\ \\  t^2 = 11t - 30 , \ \ \ \ \ \  \ \ \ \ \ \  8t - 15 = t^2 , \ \ \  \ \ \  \ \ \  t^2 = 13t -40  \\ \\  t^2 - 11t + 30\ \ \   \ \ \   \ \ \  \ \ \  t^2 -8t + 15 , \ \ \  \ \ \  \ \ \  \ \ \ t^2 -13t + 40 \\ \\ t^2 -8t-3t + 30=0 \ \ \ \ \ \ t^2 - 2t -4t + 15=0  \ \ \ \ \ \  t^2 - 1t - 13t + 40 =0

(t-6)(t-5)  \ \ \ \ \ \ \ \ \ \ \ (t-5)(t-3)  \ \ \ \ \ \ \ \ \ \ \ (t-5)(t-8)

10 2/6 - 7 5/6 i know its prob easy but i need help
miv72 [106K]

Answer: 2 1/3

Explanation:

10 2/6 - 7 5/6

You can make both a fraction by multiplying the denominator by the whole number, and then adding the numerator to that number, and keeping the denominator the same. So, 10*6 = 60 and 60 + 2 = 62 and you keep the denominator as 6, which would make 62/6

7*6 = 42 and 42 + 5 = 47 so 7 5/6 becomes 47/6

10 2/6 is equivalent to 62/6

7 5/6 is equivalent to 47/6

This just makes it easier to look at.

Now you just work through the equation.

62/6 - 47/6 = 15/6

15/6 = 2 3/6 = 2 1/3

If the blue radius below is perpendicular to the green chord and the segment BC is 7.6 units long, what is the length of the cho
galina1969 [7]

Answer:

The correct answer is A. 15.2 units

Step-by-step explanation:

The segment AB is congruent to the segment BC  eg AB≅BC Why?

We can prove it with the triangle congruent theorem, postulate side-side-angle

We are watching triangle ΔABO and triangle ΔCBO, they are congruent

first element side OB=OB - common side

second element side OA=OC=r - radius of the circle

third element angle ∡ABO≅∡CBO=90°

According to the postulate side-side-angle we can conclude that triangles

ΔABO≅ΔCBO (triangles are congruent)

If they are congruent all of their elements are also congruent and therefore also

side AB=BC  => AB+BC=AC,  which is chord  => 7.6+7.6=15.2 units

AC= 15.2 units ( chord )

Good luck!!!

Does(3, 6)make the inequality x + y ≤ 9 true?
maw [93]
If you would like to know if (3, 6) is a solution to the inequality x + y <= 9, you can calculate this using the following steps:

(3, 6) ... x = 3, y = 6
x + y <= 9
3 + 6 <= 9
9 <= 9

Result: (3, 6) is a solution to the inequality x + y <= 9.
