F(n)=2n+4 g(n) = 4n - 2 Find f (g(2))

Mathematics

Answer: f(g(2))=16

Step-by-step explanation:

Given the function f(n):

f(n)=2n+4

And the function g(n):

g(n) = 4n - 2

The first step we can apply is to find g(2). To do it, we need to substitute n=2 into the function and then we must evalute. Then, this is:

g(2) = 4(2) - 2\\\\g(2) =8 - 2\\\\g(2)= 6

Finally, in order to find f (g(2)) we need to substitute g(2) found above, into the function f(n) and then we must evaluate.

So, we get:

f(g(2))=2(6)+4\\\\f(g(2))=12+4\\\\f(g(2))=16

M=7,r=8, t=2 ; mr/t = what
galina1969 [7]

Answer:

Step-by-step explanation:

Plug in the corresponding numbers to the corresponding variables. Note that:

m = 7

r = 8

t = 2

mr/t = (7 * 8)/2

(7 * (8/2)) = 7 * 4 = 28

28 is your answer.

Given that sine of theta = 21/29, what is the value of cosine of theta, for 0° < theta < 90°?
fenix001 [56]

If the value of θ is 46.4°. Then the value of the cosine of θ will be 20/29.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The value of sine of θ is 21/29.

Then the value of θ will be

sin θ = 21/29

     θ = sin⁻¹(21 / 29)

     θ = 46.4°

Then the value of the cosine of θ will be

cos θ = cos 46.4°

cos θ = 20/29
