Answer:
B
Step-by-step explanation:
Given a sinusoidal function in the form f(x) = A Sin (Bx + C), we can say that:
A is the amplitude (if A is negative, the Amplitude is still the positive)
Period is
To get phase shift, we set Bx + C = 0 and solve for x.
Now, the function given is f(t) = -5 Sin (7t -1)
Hence, amplitude is 5
period is
and, phase shift is:
7t - 1 = 0
7t = 1
t = 1/7
Answer choice B is right.
Answer:
shaded area = 601 mm²
Step-by-step explanation:
Area of rectangle = Length * Breadth
Area of first section = 12 * 16 = 192 mm²
Area of 2nd middle section = 8 * ( 16 - 10 ) = 48 mm²
Area of the bottom section = 19 * 19 = 361 mm²
Area of total therefore = 192 mm² + 48 mm² + 361 mm²
= 601 mm²
Distance = rate (speed) x time
d = (6km/h)(2.33 hrs) (needed to convert 2h 20 mins to hours)
d = 13.98 km
