If Tanø =a/b Find the value of sinø+cosø/sinø-cosø

inysia [295]

Answer:

$\frac{b+a}{b-a}$

Step-by-step explanation:

Tan θ = $\frac{perpendicular}{base}$ = $\frac{b}{a}$

So, Perpendicular = b, base = a

Finding hypotenuse by Pythagorean Theorem:

$c^2 = a^2+b^2$

=> So, hypotenuse = c

Sin θ = $\frac{perpendicular}{hypotenuse}= \frac{b}{c}$

Cos θ = $\frac{base}{hypotenuse}= \frac{a}{c}$

So, Now finding $\frac{sin\theta+cos\theta}{sin\theta-cos\theta}$

=> $\frac{b}{c} + \frac{a}{c}$ ÷ $\frac{b}{c} - \frac{a}{c}$

=> $\frac{b+a}{c}$ ÷ $\frac{b-a}{c}$

=> $\frac{b+a}{c} * \frac{c}{b-a}$

=> $\frac{b+a}{b-a}$

Given the following equation where A = Area of a rectangle and w = width of the rectangle, what value of 'w' would maximize the

Papessa [141]

Answer:

the second option : w should be 25 units

Step-by-step explanation:

the area of the rectangle is length×width = L×W

the perimeter of a rectangle = 2L + 2W

now, we know that the perimeter is 100 units.

and we have to find the best length of W, that will then define L (to keep the 100 units of perimeter) and maximizes the area of the rectangle.

in other words, what is the maximum area of a rectangle with perimeter of 100 (and what are the corresponding side lengths)?

now, w = 625 is impossible. that side alone would be bigger than the whole perimeter.

W = 0 would render the whole rectangle to a flat line with L = 50 because of

100 = 2L + 2W = 2L + 0 = 2L

L = 50

and A = L×W = 50×0 = 0

an area of 0 is for sure not the largest possible area.

w = 50 would cause L = 0

100 = 2L + 2W = 2L + 2×50 = 2L + 100

0 = 2L

L = 0

and with L = 0 the same thing happens as with W = 0 : a flat line with 0 area.

so, the only remaining useful answer is W = 25

100 = 2L + 2W = 2L + 2×25 = 2L + 50

50 = 2L

L = 25

A = L×W = 25×25 = 625 units²

and indeed, the maximum area for a given perimeter is achieved by arranging the sides to create a square.

dmitriy555 [2]

The option first “shift right 1 unit, reflect over the y-axis, and then vertically stretch by a factor of 3” is correct.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a function f(x) = x

The above function represents a linear function.

As we can see in the graph of a function g(x)

f(x) = x

First shift right 1 unit

f(x) = x -1

Then reflect over y-axis

f(x) = -x - 1

Then stretch by a factor of 3

f(x) = -3x - 1

Thus, the option first “shift right 1 unit, reflect over the y-axis, and then vertically stretch by a factor of 3” is correct.
