She used 3/8 of the cheese. Since she used 1/2 <em>of</em> 3/4, you multiply 3/4 times 1/2. If you multiply straight across, the answer should be 3/8. If you need further explanation, just ask! Hope this helps! =D :D
Answer: B 1/m
Step-by-step explanation:
Answer:
D. The equation has a variable multiplied by itself. A squared variable.
Step-by-step explanation:
A quadratic equation will always start with a term being squared. For example, + 5x + 7 = 44. Another example would be + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!
(d) The particle moves in the positive direction when its velocity has a positive sign. You know the particle is at rest when and , and because the velocity function is continuous, you need only check the sign of for values on the intervals (0, 3) and (3, 6).
We have, for instance and , which means the particle is moving the positive direction for , or the interval (3, 6).
(e) The total distance traveled is obtained by integrating the absolute value of the velocity function over the given interval:
which follows from the definition of absolute value. In particular, if is negative, then .
The total distance traveled is then 4 ft.
(g) Acceleration is the rate of change of velocity, so is the derivative of :
Compute the acceleration at seconds:
(In case you need to know, for part (i), the particle is speeding up when the acceleration is positive. So this is done the same way as part (d).)
The answer should be 3 :)
