Answer:

Should be sin(40)=x/19

Explanation:

Sine is used for opposite over hypotenuse. In this case the opposite is X since X is on the opposite side of the degree. 19 is the hypotenuse as it is opposite of the 90 degrees.

Tan is for opposite/ adjacent. Adjacent is in this case the side without anything written on it.

Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function

Ivahew [28]

Answer:

y = 45/x

Step-by-step explanation:

Here, we want to write an inverse relationship

for an inverse relationship, the product of both variables will be equal to the constant term

Let us have the constant term as k

Thus, we have it that;

xy = k

9 * 5 = k

k = 45

So the inverse function is;

xy = 45

or y = 45/x

if y is a function of x, we can have it as;

f(x) = 45/x

1) g=-y+c/x, solve for X

Sindrei [870]

Answer:

the solution $x = \frac{c}{g-y}$

Step-by-step explanation:

Step 1:-

Given problem $g=\frac{-y+c}{x}$

here l.cm is x

$g = \frac{x y+c}{x}$

cross multiplication we get ,

$g x = x y +c$

Step 2:-

subtracting x y on both sides , we get

$g x - x y = c$

taking common 'x' we get,

$x(g-y) = c$

Final answer:-

$x = \frac{c}{g-y}$
