14 days = 2 weeks so
14 times 3 = 42
Answer:
50
Step-by-step explanation:
35 - 12 + 13 + 39 - 25 = 50
√z = 13 - 8
√z = 5
z = 5²
z = 25
In this case the z can be any number, however z cannot be less than 0 and that is the restriction. (for example; √-1 = irrational number, cannot be solved.)
Answer:
Use the Pythagorean theorem for right triangles to solve this
a^2 + b^2 = c^2 where 'a' and 'b' are the legs of the triangle and 'c' is the hypotenuse
so:
8^2 + b^2 = 17^2 solve for the second leg, b
64 + b^2 = 289
b^2 = 289 - 64= 225
b = 15
(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).)
