For the answer to the question above asking to r<span>esolve the car's velocity vector (in 2-space) into components if the car is traveling in each of the following directions. The units are km/hr, but
</span>east: 60i + 0j
<span>south: 0i - 60j </span>
<span>SE: (30√2)i - (30√2)j </span>
<span>NW: (-30√2)i + (30√2) </span>you do not need to enter units.
Answer:
Can I see the sign?
Step-by-step explanation:
Answer: (x - 2)² + (y - 14)² = 1
Step-by-step explanation:
<u>Concept:</u>
Here, we need to know the idea of the circle formula.
Circle formula: (x - h)² + (y - k)² = r²
Center = (h, k)
Radius = r
If you are still confused, please refer to the attachment below for a graphical explanation.
<u>Solve:</u>
Center = (2, 14)
Radius = 1
<em>Given formula</em>
(x - h)² + (y - k)² = r²
<em>Substitute the value into the formula</em>
(x - 2)² + (y - 14)² = (1)²
<em>Simplify</em>
(x - 2)² + (y - 14)² = 1
Hope this helps!! :)
Please let me know if you have any questions
I think your right,It would be 81.6.
Hope this helps. :D
In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
