f(x)=secxcscx

let secx=g(x)

let cscx=h(x)

therefore, using leibnitz rule,

f'(x)=g'(x)*h(x)+h'(x)*g(x)

    Since derivative of secx=secxtanx

    and derivative of cscx=-cscxcotx,

f'(x)=secxtanxcscx -cscxcotxsecx

     =1/cosx*sinx/cosx*1/sinx - 1/sinx*cosx/sinx*1/cosx

     =1/cos^2x-1/sin^2x

     =(sin^2x-cos^2x)/sin^2xcos^2x / Option1

The value of f'(x) is (sin^2x - cos^2x)/sin^2x cos^2x. Thus, option A is correct.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given;

f(x) = secx cscx

let secx = g(x)

let cscx = h(x)

Using Leibnitz rule,

f'(x) = g'(x)h(x) + h'(x)g(x)

Since the derivative of secx = secx tanx

derivative of cscx = -cscx cotx,

f'(x) = secx tanx cscx - cscx cotx secx

f'(x) = 1/cosx sinx/cosx 1/sinx - 1/sinx cosx/sinx 1/cosx

f'(x)  =1/cos^2x - 1/sin^2x

f'(x) = (sin^2x - cos^2x)/sin^2x cos^2x

Thus, option A is correct.

Answer:

the 3rd answer is the one which can actually form a proper plot off of that sentence

Answer:

The 3rd choice

Cinderella we know is the name of a princess in a story not a plot.

"In the woods" doesn't completely describe a plot.

so the answer is "The big bad wolf wants to eat the pigs, so he blows down their houses."

Answer:

So, the sum of the 3 angles in a triangle is 180.

What you would do is:

180= 73+6x-4+7x+7.

Then, you add the common coefficients:

180=76+13x

Then you subtract:

104=13x

Then you divide:

x=8.

Then substitute the x value into the A value to get 44, meaning that C is the correct answer.

Answer:

x = 180 - 89 = 91

y=3x2−2x+2

Step-by-step explanation:

Standard form of equation of a parabola is [tex]y=ax^2+bx+c[/tex]

As it passes through points (−2,18), (0,2) and (4,42), each of these points satisfies the equation of parabola and hence

18=a⋅4+b⋅(−2)+c or 4a−2b+c=18 ........(A)

2=c ........(B)

and 42=a⋅16+b⋅4+c or 16a+4b+c=42 ........(C)

Now putting (B) in (A) and (C), we get

4a−2b=16 or 2a−b=8 and .........(1)

16a+4b=40 or 4a+b=10 .........(2)

Adding (1) and (2), we get 6a=18 or a=3

and hence b=2⋅3−8=−2

Hence equation of parabola is [tex]y=3x^2 -2x+2[/tex] and it appears as shown below

$100

Step-by-step explanation:

$500 x [tex](1-40-40[/tex]%[tex])\\[/tex]

= $500 x 20%

= $100

$ 100 is for Mia expected.

Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.

Given the following data:

To find how much Mia is expected to sell her tablet:

First of all, we would determine the depreciation for the two year.

[tex]Two \;years = 0.4(2) = 0.8[/tex]

The depreciation cost:

[tex]500[/tex] × [tex]0.8 = 400[/tex]

Now, we would solve for the selling price by using the formula:

[tex]Selling\;price = Cost\;price - Depreciation\;cost\\\\Selling\;price = 500 - 400[/tex]

Selling price = $100

Therefore, Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.

Step-by-step explanation:

To find the midpoint of two given points add X1 and X2 together, then divide by 2 to get the X value of the midpoint and do the same thing for the Y value. That will get you B. From there you can see to get from point A to point C you add 10 to the x value and add 2 to the y value. Because C is the midpoint just double what you had to add to get point D (add 20 to x and add 4 to y)

Answer:

If PQRS is a parallelogram, then — PQ ≅ — RS and — QR ≅— SP . If a quadrilateral is a parallelogram, then its opposite angles are congruent. If PQRS is a parallelogram, then ∠P ≅ ∠R and ∠Q ≅ ∠S.

PQ=RS and PQ||RS implies PQRS is a parallelogram by showing that the diagonals bisect each other at O.

A quadrilateral with opposite sides equal and parallel but the angles are not right angle is called parallelogram.

Given that PQ=RS and PQ||RS .

Draw the parallelogram PQRS as in figure

To prove: PQRS is a parallelogram.

Construction: Join PS and QS as diagonals.

From the ΔORS and ΔOPQ,

PQ=RS (Given)

∠SOR=∠POQ   (opposite angles)

∠PQO=∠OSR  (since PQ=RS and PR is a traversal)

∴ΔOQS≅ΔOPQ

Hence, Op=OR and OQ=OS

Therefore , the diagonal of quadrilateral PQRS bisects each other.

Hence the given quadrilateral PQRS is a parallelogram.
