Answer:
The required function is f(x)=4sinx-1.
Step-by-step explanation:
The standard sine function is defined as
....(1)
Where a is amplitude, period is , c is phase shift and d is midline.
It is given that the maximum value is 3 and the minimum value is -5. Amplitude is half of difference between minimum and maximum.
The value of a is 4.
The period is 2π.
Midline is average of maximum and minimum.
Substitute a=4, b=1, c=0 and d=1 in equation (1).
Therefore the required function is f(x)=4sinx-1.
Answer:
Step-by-step explanation:
4 1/2 = 18/4
3 3/4 = 15/4
15/4 + 18/4 = 8 1/4 or 33/4
33/4 * 1.6/1 = 52.8/4 = 13.2
When assuming 1 mile equals 1.6 kilometers, Suzanne ran 13.2 kilometers in all.
0.25 or 1/4 or 25% or 25/100
4x+y=-9
4(k)+3=-9
4k=-12
k=-3
