Answer:

8x^4+9x^3+4x-1

Step-by-step explanation:

(6x^3 – 5x^2 + 3x – 5) + (8x^4 + 3x^3 + 5x^2 + x + 4)

Group like terms

8x^4+6x^3+3x^3-5x^2+5x^2+3x+x-5+4

8x^4+9x^3+4x-1

Answer:

\left(6x^3-5x^2+3x-5\right)+\left(8x^4+3x^3+5x^2+x+4\right)

Combine like terms

=8x^4+6x^3+3x^3-5x^2+5x^2+3x+x-5+4

Add: -5x²+5x²=0

=8x^4+6x^3+3x^3+3x+x-5+4

Now add 6x³+3x³=9x³

=8x^4+9x^3+3x+x-5+4

Add like terms 3x +x=4x

=8x^4+9x^3+4x-5+4

Now add -5+4=-1

=8x^4+9x^3+4x-1

Solve x^2+4x+8. What is the vertex?
LenKa [72]

Answer:

(-2,4)

Step-by-step explanation:

Well to start with there is a vertex formula which is -\frac{b}{2a} =h\\, f(h)

Your initial equation is x^2+4x+8 where ax^2+bx+c. So you would plug in your numbers -\frac{4}{2(1)}=-\frac{4}{2} =-2 we know know that h=-2 so plug in h in f(-2) which would be (-2)^2+4(-2)+8 = 4-8+8 = 4 which would make the vertex (-2,4)

A particle moves along line segments from the origin to the points (2, 0, 0), (2, 5, 1), (0, 5, 1), and back to the origin under
kondaur [170]

A particle moves along line segments from the origin to the points, work done is mathematically given as

W=184.5units

<h3>What is the solution of an equation that matches the model.?</h3>

Considering line segments from (0,0,0)origin to (2,0,0) , (2,5,1) and (0,5,1) under the infulence of force

Generally,  the equation for force is mathematically given as

F = z2i + 5xyj + 2y2k

Therefore, Considering u*v

u * v = (u_1j+u_2j+u_3k) * (v_1i+v_2j+v_3k)

u* v = u_1v_1(i * i) + u_1v_2(i * j)+u_1v_3(i * k) + u_2v_1(j * i) + u_2v_2(j * j)+u_2_3(j* k) + u_3v_1(k * i) + u_3v_2(k * j)+u_3v_3(k * k)

Where

i * i = j *j=k * k=0

Hence

u* v = u_1v_2k-u_1v_3j-u_2v_1k+u_2v_3i +u_3v_1j - u_3v_2i

u = (u_1,u_2,u_3) = (0,5,1)\\\\v = (v_1,v_2,v_3) = (-3,0,0)

The normal equation formed

-2y + 15z = 0

z= (1/5)y

Considering the level surface and differential surface area

h(x,y,z) = -y + 5z =0

dS = |grad(h)| dA

In terms of the x and y coordinates of (2,0,0) and (2,5,1) and (0,5,1), we can state that the ranges are 0 to 3 and 5 respectively we have

0 \leq x \leq 2 \ and \ 0 \leq y \leq 5

Using strokes theorem to evaluate

F = z2i + 5xyj + 2y2k

curl \ F = 4yi+2zj+5yk = (4y,2z,5y)

curl \ F * nds= \frac{1}{5}(-2z + 25y)\ dy \ dx

In conclusion, The work done is

W=\int _CF *dr

\int _C F * dr = \int \int curl \ F * n ds

\int _C F *dr = \frac{123}{2}\int_0^3 \ dx

\int _C F * dr = \frac{123*3}{2}

W= 184.5units
