The value of cos theta is 2/√29

<h3>Trigonometry identity</h3>

A trigonometry identity are expressions expressed as cosine, tangent, sine.

Given the following trigonometry identity

cot theta = 2/5

1/tan theta = 2/5

tan theta = 5/2

Determine the hypotenuse

hyp² =5^2 + 2^2

hyp² = 25 + 4

hyp = √29

Determine the value of cos theta

cos theta= adj/hyp

cos theta= 2/√29

Hence the value of cos theta is 2/√29

Which value of x is a solution of the inequality? ​
Levart [38]
Hello, and thank you for posting your question here on brainly.

A correct answer to this can be B. x = 3 look at the work provided below. 

Subtract 5 from both sides, to remove it.

3x + 5 ≤ 14 ==> 3x ≤ 9

Divide both sides by 3, to remove it.

3x ≤ 9 ===> x ≤ 9/3

Solve 9/3.

x ≤ 9/3 ===> x ≤ 3

Hope this helps! ☺♥

To find an inverse function first replace f(x) with y

f(x) = 8*sqrt(x)
y = 8*sqrt(x)

Then, simply switch the places of the x and y.

x = 8sqrt(y)

Now solve for the new y by squaring both sides (to get rid of the root)

x^2 = 64y

divide to get

y = x^2/64. This is the inverse function or option C.
