(3q) find the amplitude and period of f(t)= -tan.0t

option b

amplitude none ; period 5π/2

Step-by-step explanation:

Given in the question a function,

f(t)=-tan(0.4t)

The tangent function does not have an amplitude because it has no maximum or minimum value. The period of a tangent function, y=atan(bx),is the distance between any two consecutive vertical asymptotes.

Period = π/|b|

           = π/2/5

           = 5π/2

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
