A turntable rotates counterclockwise at 78 rpm. A speck of dust on the turntable is at an initial angular position of 0.45 radia

SashulF [63]

Answer:

Displacement will be 11 revolution and 1.02π radian

Step-by-step explanation:

We have given that initial angular position = 0.45 radian

Angular speed $\omega =78rpm=\frac{2\times \pi\times 78}{60}=8.164rad/sec$

Time is given as t = 8.8 sec

So angular displacement in 8.8 sec

$\Theta =8.8\times \times 8.164=71.8432radian$

As he has already covered 0.45 radian

So total angular displacement = 0.45 + 71.8432 = 72.2932 radian

We know that 1 revolution = 2π = 2×3.14 = 6.28 radian

So 11 revolution = 11×6.28 = 69.08 radian

Left dispalcement = 72.2932 - 69.08 = 3.2132 radian = 1.02π radian

If f(x) = 2x + 3 and g(x) = 3x - 9, find (f + g)(x).

coldgirl [10]

Answer:

5x-6

Step-by-step explanation:

f(x) = 2x + 3

g(x) = 3x - 9

f(x) + g(x) = 2x + 3 + 3x-9

= 5x-6
