Using the binomial theorem, expand the expression (4 + y) to the power of 4

Answers

Answer:

When raised to the power of 4, the binomial (4 + y) expands to:

[tex]y^4 + 16y^3 + 96y^2 + 256y + 256[/tex]

Step-by-step explanation:

[tex](4 + y)^4 \\= (y^2 + 8y + 16)^2\\= y^4 + 8y^3 + 16y^2 + 8y^3 + 64y^2 + 128y + 16y^2 + 128y + 256\\= y^4 + 16y^3 + 96y^2 + 256y + 256[/tex]

Solve the system of equations. − 3 x + 2 y = 56 − 5 x − 2 y = 24 −3x+2y=56 −5x−2y=24

Answers

Step-by-step explanation:

-3x + 2y = 56

+ (-5x - 2y = 24)

=> -8x = 80, x = -10.

Therefore -3(-10) + 2y = 56, 30 + 2y = 56, y = 13.

Hence x = -10 and y = 13.

Answer:

x = -10 and y = 13.

Answers

9514 1404 393

Answer:

A: x = -1 and y = 3

B: x = 12 and y = 16

Step-by-step explanation:

In each case, you can add the opposite of the constant to find the variable.

Equation A

(x +yi) +(4 -7i) = (3 -4i)

(x +yi) +(4 -7i) -(4 -7i) = (3 -4i) -(4 -7i) . . . . . add -(4-7i) to both sides

x +yi = (3 -4) +(-4-(-7))i = -1 +3i

x = -1 and y = 3

Equation B

(x +yi) -(-6 +14i) = (18 +2i)

(x +yi) -(-6 +14i) +(-6 +14i) = (18 +2i) +(-6 +14i) . . . . . add (-6 +14i) to both sides

x + yi = (18 -6) +(2 +14)i = 12 +16i

x = 12 and y = 16

Answer:

In equation A: x=-1 and y=3

In equation B: x=12 and y=16

I give 20! Find the surface area. And without explanation please, I don’t have enough time.

Answers

Answer:

816 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.

✔️Surface area of the larger rectangular prism:

Area = L*W*H = 20*5*6 = 600 cm²

✔️surface area of the smaller rectangular prism:

Area = L*W*H = 12*4*6 = 288 cm²

✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.

Area = L*W = 12*6 = 72 cm²

Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².

5x+4y=-34 and y=3x

Answers

Answer:

x = -2 ; y = -6

Step-by-step explanation:

Let y = 3x be eqn.1

So putting eqn.1 in 5x + 4y = -34 gives ,

[tex]5x + 4y = - 34[/tex]

[tex] = > 5x + 4(3x) = - 34[/tex]

[tex] = > 5x + 12x = - 34[/tex]

[tex] = > 17x = - 34[/tex]

[tex] = > x = \frac{ - 34}{17} = - 2[/tex]

Putting the value of x in eqn.1 gives :-

[tex]y = 3x = 3 \times ( - 2) = - 6[/tex]

(c) Let f (x)= x3 , g(x)= x+5. Find (f •g)(x)
(d) Find the derivative of y = 3+ x^2+ x^3y^3.

Answers

Answer:

a) A-B = { 1 , 3, 5 }

b) The remainder is 50

c) f + g)(x) = x⁴+ 5x³

d) [tex]\frac{dy}{dx} = \frac{2x- y^3(3x^2)) }{ 1- x^3 3y^2}[/tex]

Step-by-step explanation:

Step(I):-

1) a)

Let A = { 1, 3, 5, 7 } and B = { 7 , 14 , 21 }

A - B = {1,3,5,7} - { 7,14,21}

A - B = { 1 , 3, 5}

Given f (x)=3x³−11x−48

x-1 ) 3 x³ - 11x -48 (- 3x²-3x -2

-3x³ +3x²

3x²-11x-48

-3x²+9x

2x -48

-2x +2

The remainder is 50

c) Given f(x) = x³ and g(x) = x + 5

(f. g)(x) = f(x) .g(x) = x³ . (x+5) = x³(x) + 5 x³ = x⁴+ 5x³

Given function y = 3 + x²+x³y³ ...(I)

By using derivative formulas

y = xⁿ

[tex]\frac{dy}{dx} = n x^{n-1}[/tex]

Apply d/dx ( UV) = U V¹ + V U¹

Differentiating equation (I) with respective to 'x' , we get

[tex]\frac{dy}{dx} = 0 + 2x + ( x^3 3y^2(\frac{dy}{dx} )+ y^3(3x^2))[/tex]

[tex]\frac{dy}{dx} - ( x^3 3y^2(\frac{dy}{dx} )= 2x- y^3(3x^2))[/tex]
