Make the indicated trigonometric substitution in the given algebraic expression and simplify(x-25)/x = Sin y0
Strike441 [17]

Answer:

x = 25 /(1 − sin(y )) and y ≠ π/2  +2πn

Step-by-step explanation:

Let's solve and simplify for x,

(x − 25 )/ x  = sin(y)

Let's multiply both sides by x

((x − 25 )/x) *x= sin(y)*x

Then,

x − 25 = sin(y) * x

Let's add 25 to both sides

x − 25 + 25 = sin(y) * x + 25

If simplify again,

x = sin(y) * x + 25

Then we need subtract sin y x from both sides

x − sin(y) * x = sin (y)* x + 25 − sin (y)* x

It will equal:

x − sin (y)* x = 25

Factor x−sin(y) x: x(1−sin(y) ), then we get:

x (1 − sin(y)) = 25

Finally we need divide both sides by 1 − sin(y) ; y ≠π /2 + 2πn

And it will give us this equation:

x = 25 /(1 − sin(y )) and y ≠ π/2  +2πn

What is 0.4(0.3x-1)=2+0.75x ?
Andrews [41]
1st disribute .4 through the parentheses.

.4 (.3x-1)=2+.75x
.12x-.4=2+.75x

subtract .12x from each side

-.4 = 2 + .63x

subtract 2 from each side

-2.4 = .63x

Divide each side by .63

-3.81 = x

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
baherus [9]

Answer:

The answer is 1/4 probability because in the first scenario, 4 of the men could he chosen and there are 16 total options.

In the second scenario, there are 2 slots for the men and 8 total slots. This means they have a 1/4 chance of being chosen.

hope this help :>
