Answer:
- 4x + 36
Step-by-step explanation:
( - 6)² = ( - 6)( - 6)
Each term in the second factor is multiplied by each term in the firs t factor, that is
( - 6) - 6( - 6)
Distribute both parenthesis
= - 2x - 2x + 36 ← collect like terms
= - 4x + 36
Answer:
Step-by-step explanation:
(10 + 5)/2 = 15/2
(2 - 7)/2= -5/2
(15/2, -5/2)
The correct answer would be A. x=20/3 because it is proportional.<span />
Answer with Step-by-step explanation:
We know that the components of velocity are obtained from position as
Using the given values we obtain
Similarly
The the velocity function can be written as
The components of acceleration are obatined from the components of velocity as
Using the given values we obtain
Similarly
The the acceleration function can be written as
Thus at time 't=1' the velocity function becomes
Thus the component of acceleration in the direction of the given vector can be found by taking the dot product of the 2 vectors
Thus we get
Similarly the dot product is obtained for acceleration as
