Step-by-step EXPLANATION:

MAKE me the BRAINLIST

ANSWER: pls mark me as a brainliest friend pls, I have GIVEN step by step explanation.

Step-by-step explanation:

Step 1 : value of A = ║1221 ║ = - 1221

Value of f(x) = (1 + x) (1 - x)

Step 2 : as we don’t have the simplified value of f(x), we have to simplify it

f(x) = (1 + x) (1 - x)

⇒ ( a + b ) ( a - b ) =

So, (1 + x) (1 - x) = -

= 1 -

So, f(x) = 1 -

Step 3 : now we have to FIND the value of “ f ”.

f(x) = 1 -

= f = 1 -

= f = 1 - x

Step 4 : we have found the value of both A and f. Now we have to find the value of f(a).

F(a) = f × a

F × a = ( 1 - x ) ( - 1221 )

= (1 × - 1221) ( -x × -1221 )

= (- 1221) ( 1221 x )

= - 1490841 x

Therefore, the value of f(a) is “ - 1490841 x ”.

Hope it’s useful friend…

Answer:  

Given:

A Cubic POLYNOMIAL is given as shown

Having Factors ( z-1 ) and ( z + 3 )

To Find:

The VALUE of m and n in the given cubic Polynomial

Solution:

( z-1 ) and ( z+3 ) are the factors of P(x)

Then z = 1 and z = -3 must be it's zeros

Putting z = 1 in P(x)

-------(1)

---------(3)

Similarly putting z = ( -3 ) in p(x)

---------(4)

HELLO

Have a GREAT DAY AHEAD

Let the COST of 1- Kg of a goods be = Rs 100. If he earns a profit of 30%, he should sell the goods weighing 1- Kg (1000- g) for Rs 130.

Since he is a dishonest shopkeeper, he SELLS 900- g (0.9- Kg) of his goods as 1- kg for Rs 130.

So the ACTUAL profit percentage is

= (130–90)/90 x 100

= 40/90 x 100

= 44.44%

I HOPE this will HELP to SOLVE your PROBLEM.

EXPLANATION.

Equation of tangent and equation of NORMAL to the giving curve to the.

⇒ x²/a² + y²/b² = 1.  at (a cosθ, B sinθ).

As we know that,

⇒ x²/a² + y²/b² = 1.

Differentiate w.r.t x, we get.

⇒ 2x/a² + 2y/b². (dy/dx) = 0.

⇒ 2y/b². (dy/dx) = - 2x/a².

⇒ dy/dx = (-2x/a²)/(2y/b²).

⇒ dy/dx = (-2x/a²) x (b²/2y).

⇒ dy/dx = -xb²/ya².

PUT the value of (a cosθ, b sinθ) in the equation, we get.

⇒ dy/dx = -(a cosθ) x b²/(b sinθ) x a².

⇒ dy/dx = (- bcosθ)/(a sinθ).

As we know that,

FORMULA of equation of tangent.

⇒ (y - y₁) = m(x - x₁).

Put the value in the equation, we get.

⇒ (y - b sinθ) = (- bcosθ)/(a sinθ) (x - a cosθ).

⇒ (a sinθ)(y - b sinθ) = (- bcosθ)(x - a cosθ).

⇒ (a sinθ)y - absin²θ = (- bcosθ)x + abcos²θ.

⇒ ay sinθ + bx cosθ = abcos²θ + absin²θ.

⇒ ay sinθ + bx cosθ = ab.

⇒ bx cosθ + ay sinθ = ab.

⇒ (bx cosθ)/ab + (ay sinθ)/ab = 1.

⇒ x/a cosθ + y/b sinθ = 1.

As we know that,

Formula of equation of normal.

⇒ (y - y₁) = -1/m(x - x₁).

⇒ (y - b sinθ) = (a sinθ)/(b cosθ) (x - a cosθ).

⇒ (b cosθ)(y - b sinθ) = (a sinθ)(x - a cosθ).

⇒ by cosθ - b²sinθ.cosθ = AX sinθ - a²sinθ.cosθ.

⇒ ax sinθ - by cosθ = (a² - b²) sinθ.cosθ.

⇒ (ax sinθ)/(sinθ.cosθ) - (by cosθ)/(sinθ.cosθ) = (a² - b²).

⇒ (ax)/cosθ - (by)/sinθ) = (a² - b²).

⇒ ax secθ - by cosecθ = (a² - b²).

Step-by-step EXPLANATION:

here is your ANSWER of your QUESTION HOPE it will HELP you

GIVEN :-

The area of a TRAPEZIUM is 34 cm square and it's height is 4 cm one of the parallel sides of the trapezium is 10 cm

To FIND :-

Other parallel SIDE

Solution :-

We know that

⇒ Area = 1/2 × (a + b) × h

Let the other parallel side be b

⇒ 34 = 1/2 × (10 + b) × 4

⇒ 34 = 2(10 + b)

⇒ 34 = 20 + 2b

⇒ 34 - 20 = 2b

⇒ 14 = 2b

⇒ 14/2 = b

⇒ 7 = b

∴ Other parallel side​ is 7 cm
