Particle x moves along the positive x-axis so that it's position at time t is less than equal to 0 is given by x(t)= 5t^3 - 9t^2 + 7. Is particle x moving toward the right at time t=1?

Step-by-step explanation:

Given the position of the particle expressed using the expression;

x(t)= 5t^3 - 9t^2 + 7 where;

x moves along the positive x-axis

when t = 1

x(1) = 5(1)^3 - 9(1)^2 + 7

x(1) = 5 - 9 + 7

x(1) = -4 + 7

x(1) = 3

Since the position of the particle is positive at t = 1, hence the particle is moving towards the right at time t = 1

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
