Answer:
Step-by-step explanation:
Options a and d are right.
The given function is of the above form
![y=acosb(x-p)+k](https://tex.z-dn.net/?f=y%3Dacosb%28x-p%29%2Bk)
We have here a=1/4 :b=1 : p = -pi/3: and k=-1
Hence we have an amplitude of 1/4, horizontal shift of pi/3 to the right,vertical shift of 1 unit down and vertical shrink of 1/4
Hence the correct choices would be
1) It has amplitude 1/4
d) Horizontal shift of pi/3 to the left
Other options are false

Answer:
Angle T = 79°
Step-by-step explanation:
From the question given above, the following data were obtained:
Side opposite U (u) = 2.7 cm
Side opposite S (s) = 3.9 cm
Side opposite T (t) = 4.3 cm
Angle T =?
The value of angle T can be obtained by using cosine rule as illustrated below:
t²= s² + u² – 2suCosT
4.3² = 3.9² + 2.7² – 2 × 3.9 × 2.7 × Cos T
18.49 = 15.21 + 7.29 – 21.06 × CosT
18.49 = 22.5 – 21.06 × CosT
Rearrange
21.06 × Cos T= 22.5 – 18.49
21.06 × Cos T = 4.01
Divide both side by 21.06
Cos T = 4.01 / 21.06
Cos T = 0.1904
Take the inverse of Cos
T = Cos¯¹ 0.1904
T = 79°
