Answer:
Option A. is the correct option.
Step-by-step explanation:
We have to get the simplified form of sin (.6x)-sin(.4x)
As we know the identity sinA- sinB = 2 cos(A+B)/2.sin(A-B)/2
We apply the identity in the given expression
sin(.6x)-sin(.4x) = 2 cos(.6x + .4x)/2.sin(.6x - .4x)/2
= 2 cos(x/2).sin(0.2x/2) = 2 cos(0.5x).sin(0.1x)
Therefore option A is the correct option.
Answer:
∞
Step-by-step explanation:
In many instances, the term "amplitude" is used to refer to half the range. The range of any tangent function is (-∞, ∞), so its amplitude is ∞ regardless of any multiplier or offset.

Perhaps you're expected to say the absolute value of the coefficient of the trig function. In that case, the "amplitude" is 4/5.
Answer:
£37.80
Step-by-step explanation:
To find the sale price of a jacket during a 30% off sale, first subtract 0.30 from 1.00, obtaining 0.70, and then multiply the regular price (£54) by 0.70:
0.70(£54) = £37.80
Answer:
32
Step-by-step explanation:
32 is the constant of proportionality. Its represents thr average number of miles per gallon.
Volume=[(4πr^3)/3]/2=[(4π(70)^3)/3]/2 is approximately 718378 ft^3
