Evaluate: 29 + 1/7x when x = -1/2
= 29 + 1/7(-1/2)
= 29 + (-1/14)
= 28.93
W to the fourth power is different than to the second power. So if you combine like terms which is 5w to the fourth power and -25w to the fourth power to get you to -20w to the fourth power and then add the 30w to the second power so that is -20w to the fourth power plus 30w to the fourth power.
Answer:
Your choice is correct.
Step-by-step explanation:
The amplitude (multiplier of sin( )) is half the diameter, so is 17.5. The midline (value added to the sine function) is the difference between the maximum (50) and the amplitude (17.5), so is 50-17.5 = 32.5. All choices have the correct frequency.
The function will look like ...
f(t) = 17.5·sin(2πt/5) +32.5 . . . . . as you have marked
12.2 ft because the Pythagorean theorem ( a^2 +b^2 = c^2) given this c is square root of 149 which is 12.2
