A particle, moving in a straight line, passes through a fixed point O. Its velocity v ms^-1, t seconds after passing
through O, is given by v = cos 3t + sin 3t.

a) Find the value of t when the particle is first instantaneously at rest.

b) Find the acceleration of the particle when t = π

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

Ineed no it anyone can see this
