The smallest positive solution of tan bx = 2 is x = 0.3. Determine the general solution of tan bx = 2.
Contact [7]

The general solution of tan(b·x) = 2, given that the smallest positive solution is x = 0.3, is presented as follows;

\mathbf{ x =0.3 +  \dfrac{n \cdot \pi}{b}}

The given smallest positive solution of tan (b·x) = 2 is x = 0.3

The general solution of tan (b·x + c) = m, is given as follows;

\mathbf{x = \dfrac{\alpha  - c}{b}  + n \cdot \dfrac{\pi}{b}}

α = arctan(m) = x₀

The minimum positive value of the general solution is therefore presented as follows;

x_{min \ positive} = \dfrac{\alpha  - c}{b}  + 0 \times \dfrac{\pi}{b} = \dfrac{\alpha  - c}{b}

\mathbf{x_{min \ positive} = \dfrac{\alpha  - c}{b}}

In the given function, tan (b·x), we therefore, have;

c = 0, m = 2,  \dfrac{\alpha  - c}{b} = 0.3

The general solution of tan(b·x) = 2, is therefore;

\mathbf{x =0.3 +  \dfrac{n \cdot \pi}{b}}

fathers age is 5 times the sons age. if the sum of their ages is 60 yearsm what willbe their ages after 5 years.? step by step p
Vlada [557]

Step-by-step explanation:

let father's age be f yr old and son age be s yr old

f = 5s -(1)

f + s = 60 -(2)

sub (1) into (2):

5s + s = 60

6s = 60

s = 10

f = 60 - 10 = 50

in 5 yr time, father age = 50 + 5 = 55

son age = 10 + 5 = 15

Quick !<br> The perimeter of the rectangle below is 118 units. Find the length of side AD.
NARA [144]

Answer:

24

Step-by-step explanation:

the perimeter is all sides added up

therefore to solve for "z"

3z + 3z + 4z + 3 + 4z + 3 = 118

simplify

14z + 6 = 118

isolate z by first subtracting 6 from both sides and then dividing by 14 for both sides

z=8

plug z into side CB as AD and CB are congruent
